It's theoretically possible to change this; Gala (the elementary OS window manager) can be extended by plugins. There even is a plugin changing the Alt+Tab behaviour called gala-alternative-alt-tab.

You can take a look at Tom's (the developer) document, which describes the plugins future features and functionality.

However, as the GitHub page points out, this is alpha software, so there is no package available via repositories and as the last commit was in April, it may not even work at all. Tom has been very busy the past months and this plugin isn't his top priority. So take this information with a grain of salt - It is not recommended to install it on your system.


WinFast TV2000 jak zainstalować w elementary

Since elementary OS is based on Ubuntu, you may find the process listed on the Ubuntu Forum helpful. HOWTO: Winfast TV2000 XP Series card on Ubuntu. The steps are simple. First, you may need to uninstall the tvtime package, not sure. Then:

sudo rmmod bt878
sudo rmmod tuner
sudo rmmod bttv
sudo modprobe bttv card=34 tuner=43
sudo apt-get install tvtime

You might need to unmute a channel or two in alsamixer.


Yes, they both work great on elementary. I'm using the beta of Firefox Quantum without issue and both the stable and dev version of Chrome. Again, they both run great.

You can download Firefox from the App Center. To install Chrome you can either install via:

wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
sudo dpkg -i --force-depends google-chrome-stable_current_amd64.deb
sudo apt-get install -f

or manually download the .deb file from the Chrome website and then in elementary install Eddy from the App Center to install the deb file.

But honestly if you're trying to install this on a 2007 machine you might have some issues unless you go with something really lightweight. I would recommend Xubuntu or Lubuntu. Something that runs a lighter desktop.


Curated apps are advertised in AppCenter's home page when you open the app and they are listed first in any category listing before non-curated apps, as you seem to have discovered by your comment.


At this point if you don't have really done any kind of customization, you might just reinstall the OS without the encryption.


How to Check if Your elementary System Is 32-bit or 64-bit

Elementary is 64 bit only and has been for a while. However, you can check your CPU's abilities with:
sudo lshw -class processor

That will give you a bunch of information about your CPU. You can look specifically for:

width: 64 bits

rebooted and it worked


How do I install the drivers for my Nvidia GTX 970?


Thanks for your feedback... :) Well, I think I sort of fixed it at least temporarily in the meantime; seems the Bluetooth component in some way was (per software?) disabled via rfkill which I "fixed" - but I have no idea how that happened. It's working again, now, and I hope it will stay that way. :)


Ruby on Rails on elementary OS, uglifier error when starting server

Actually having meteor installed doesn't count as having nodejs installed. nodejs is required for uglifier package, so simple: apt install nodejs resolves the issue.


Are we allowed to use the documentation stylesheets?

Legal

Yes, you can re-use the styles found here. MIT grants you usage rights for pretty much everything. What you cannot do is use the "elementary" name or logomark in such a way as to suggest endorsement.

Ethical

Whether or not it is in the "spirit" of elementary to share this work depends on what you are doing with it. Providing a template for use by other developers with better documentation is a noble enough cause, but the true elementary spirit would be making sure that it works consistently and works well.


dconf-editor is working as it should.

Though it seems it is not posssible to change time format in wingpanel anymore using dconf-editor anymore.

On my (freshly installed) system there is only an option to show week numbers.

Also elementary-tweaks does not show an option to change the time format, see https://github.com/elementary-tweaks/elementary-tweaks.


Monitor resolution too high and not saving

what graphics card do you have, which version of ElementaryOS are you running

You can use the following command in the terminal to decide which graphics card you have

sudo lspci|grep VGA

To me it seems like a driver issue so the answer about it depends on the card and driver you are using.


How to connect to Elementary using X2GO?

As per x2go Client's "Desktop Environment Compatibility" page, Elementary OS's "Pantheon" shell (of the Gnome Desktop Environment) is officially not supported.  You could open a new bug report with "wishlist" severity, following the instructions here.  It won't be easy to support Pantheon, because there's already other rather difficult problems blocking x2go client's support of the newest Gnome versions.

Another option might be to install a second desktop environment (such as XFCE, or LXDE, which x2go client fully supports) on your Elementary OS box, alongside Pantheon.  But that would be a kludge, and I wouldn't be surprised if you encountered many problems and annoyances, because XFCE and LXDE wouldn't use Elementary's "switchboard" technology.  Elementary OS strongly assumes you'll use Pantheon, and only Pantheon.  You can't choose between DE's at the lightdm login screen, for instance.

If x2go is crucial for you right now, consider switching to a Linux distro such as LXLE, which uses LXDE from the get-go.  Just like Elementary, LXLE is designed to be very lightweight.


How to use maya calendar as to-do application

Maya is currently not designed to support this. According to elementary guidelines it also should not support this: they adhere the principle of apps doing one thing, and doing that in a great way. Calendars are not todo lists, so there are other apps better suited for this purpose. I.e. Go For It is a very nice app for this.


Remove OnlyShowin=Pantheon from the .desktop file. I didn't have to add OnlyShowin=Pantheon to get my .desktop file to show in Slingshot.


After changing your keyboard settings, do in terminal:

setxkbmap -query

You should see the options you have chosen,e.g:

    setxkbmap -query
rules:      evdev
model:      pc105
layout:     de
variant:    mac
options:    terminate:ctrl_alt_bksp

You can try setting this command:

setxkbmap -model pc105 -layout pl -option 'lv3:lwin_switch'

with your options. I'm not sure if this is going to be permanent, try it out.

If it's not permanent, there are 2 options:

changing /etc/default/keyboard:

in terminal:

sudo nano /etc/default/keyboard

A text-file will be opened where you can write your input. This should be loaded upon startup.

putting your command in Startup-Aplications:

Go to System-Settings->Applications and add a new Startup-Apllication with your command above, eg:

setxkbmap -model pc105 -layout pl -option 'lv3:lwin_switch'

EDIT:
you can see all the possible layouts and options in this file: /usr/share/X11/xkb/rules/base.lst

Setting up OS X-style multi touch gestures on elementary OS

In the show notes of the first episode of simply elementary they covered the basic setup of a configuration file of touchegg. Their comments on the script are as follows:

  It’s a very basic configuration that allows you to switch between workspaces and view the multitasking view with three-finger swipes. It is very similar to the default Mac OS X gestures if you are used to them. Note: It assumes that you use natural scrolling (the system default), otherwise the left/right swipe directions might feel backward to you. If you prefer the swipe directions to be reversed you can always modify the file to change the behavior.

You can download the configuration file from the Dropbox of Nathan Dyer here.
I know this only answer part of your questions, but I hope it will help you on your way. Maybe by studying the configuration file you can figure out how to set up the rest you want.


You can use Super + space to open and hide the menu too.


I need help in doing the partitions for the installation process

First of all you need to create a new partition on your os drive. You can shrink your Windows partition using the Disks Management Tool that comes on Windows.
Then just leave the empty space you want for elementary. You need 10 GiB at least, but I'd recommend to have 30 Gib or more to have some extra space to install programs.

Now Reboot, then plug your elementary OS bootlable USB and install it. You can also go into advanced settings on Windows 8-10 and select "reboot and boot from usb".

After that, when you reach the partitioning stage you should be able to format that empty space and create a new Ext4 partition. Just set it as / so that elementary OS is installed there. If you have less than 8 Gib of RAM you should also create a SWAP partition of the same size as your RAM.


Yes, this is a known issue. Not sure will it be resolved or not since the elementary team is working on developing its own application centre for the next release.


Unable to install on Dell with Killer WiFi

I currently have 2 DELL with Killer wifi card and they have always works with the version of elementary OS 5.0 and 5.1 and with kernel 4.X and the new 5.X ( 5.0.0-37-generic for elementary OS Hera)

I think you did not check the option
install third party software for graphics and wifi hardware and additional media formats during the window Update and other software

If you want update your Kernel in elementary Hera you can do that with this command

$ sudo apt install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04


How to enable automatic login after installing elementary OS Loki

You can try to do so using command line. Here's the help page. In particular you need to use,

sudo nano /etc/lightdm/lightdm.conf

and thereafter, add the following lines,

[SeatDefaults]
autologin-user=<YOUR USERNAME>
autologin-user-timeout=0
user-session=ubuntu
greeter-session=unity-greeter

This is slightly different than what's mentioned in help page since that's for older release.

Edit - Here's another answer.


You have two options. You can run the app from the terminal as long as you add an ampersand at the end of your command. This will prevent webstorm from closing from the terminal.

Or, option two and the most practical is to create a .desktop file which will create a launch icon in the Slingshot menu.

Here is an example file:

[Desktop Entry]
Version=x.y
Name=Webstorm
Comment=This is my comment
Exec=/home/user/Documents/webstorm.sh <--- enter the full path to you app
Icon=/home/user/Pictures/icon.png <-- optional but nice to have
Terminal=false
Type=Application
Categories=Utility;Application;

Name the file whatever with a .desktop extension and place it in ~/.local/share/applications


Requires installation of untrusted packages in elementary OS

Option 1:

To solve this install y-ppa-manager.To install open terminal and run:

sudo add-apt-repository ppa:webupd8team/y-ppa-manager
sudo apt-get update
sudo apt-get install y-ppa-manager

Now run y-ppa-manager from terminal.

When main y-ppa-manager window openend,click on Advanced

From the advaced list--> click on Try to import all missing GPG keys then click OK.

Option 2:

Open Software and Updates, change download from to  : Main Server ,then try again.

Option 3:

Open terminal and run the following commands:

sudo apt-get clean
cd /var/lib/apt
sudo mv lists lists.old
sudo mkdir -p lists/partial
sudo apt-get clean
sudo apt-get update

Is it possible to install a more up-to-date kernel in Freya?

System Recovery

If you are now unable to boot, press (or tap) Shift while booting (right after BIOS post screen) to show the GRUB menu. You can choose an older kernel to boot into from the recovery options menu item.

Install 3.19 Kernel

sudo apt-get install linux-generic-lts-vivid

The above command will install the backported 3.19 kernel from the LTS Enablement Stack. You may have more luck with that one. It installed flawlessly for me in any case. See this answer for instructions for installing other kernel versions.

Troubleshooting

Alternatively you could boot to a recovery mode console (from GRUB) and examine your logs for clues as to why it is stalling on boot. Especially the following...

less /var/log/kern.log (Shows Kernel messages)

less /var/log/Xorg.0.log (X server logs)

less /var/log/syslog (Overarching system log)


Run the following commands to remove the driver

sudo apt-get purge fglrx*
sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
sudo reconfigure xserver-xorg

After running the commands reboot your computer.

WARNING : These commands might destroy your system


External monitor resolution on Macbook Pro is not permanent, reverts to original when lightdm is restarted

I had pretty much the same problem with display on an external monitor - display was fitted badly; I hardly could see wingpanel or plank.

I solved it with changing config file in /boot/ directory.

In this file you need to find disable_overscan and change it's value to 1.
Then a bit further down you'll find

overscan_bottom=48
overscan_left=48
overscan_right=48
overscan_top=48

you can change these values to fit your display into monitor.

Then save it  and restart computer. It should be fine after few times. :)


In system settings, choose Applications
Click on startup tab
In the left bottom corner you will see a '+' button, click it
You will find a box to type in a custom command, type in the conky there.


Turning on NVIDIA propritary driver on Macbook Pro makes it hang on reboot

I had the same laptop and I tried to make it work with Ubuntu back then, but I guess your case is very similar.
AFAIK there is no way to get automated graphics switching to work as it is an Apple-designed hardware-based graphics switching solution which differs greatly from Nvidia's Optimus (that means bumblebee won't work).

I essentially boils down to two choices:

Leave your setup as is (intel driver)
Boot in non-EFI mode so that the MBP EFI will automatically switch to the Nvidia card (you won´t be able to use the power-efficient intel card that way untill reboot) by following the answer I outlined here


ASUS ZenBook Pro UX550VE Can't Install OS, Goes Straight to TTY1 and Can't Use sudo Commands

How to create an app menu item to run TeamSpeak3 installed app

If you want to save or modify a file or folder as root you can open Files as root, right-click in Files and open Files as Administrator.

Also you can to open Scratch with sudo and save your file teamspeak.desktop in /usr/share/applications/ folder.

sudo scratch-text-editor

Of course if you want to create just a entry in the menu without be root, you can put your own .desktop files in "~/.local/share/applications/". It's more safe.


I usually leave some unallocated space and then boot the installation usb. In there there's an option to manually edit the partitions and such so I just create a new ext4 partition and set it to / (which is the root directory).

If you have less than 8gb of ram then it's a good practice to leave 4gb or so to create a swap partition. You can do it at the same time you create your root partition.

If you don't want to mess with this, there's an option called "install elementary alongside of windows" that should do the same. However in the past I had issues with it so i'm not sure if it works now.


How to run multiple command sequentially?

You can make shell scripts to achieve this. A shell script usually starts with #!/bin/bash. Let's say you want to execute sudo apt update and ls but you don't want to type it every time. So a shell script for that is,

#!/bin/bash
sudo apt update
ls

Save it with ".sh" extension and execute sudo chmod +x file_name.sh to give the file executable permission. Then you can execute the script by ./file_name.sh.
Take a look here, described well in this answer at askubuntu.


Touchpad sensibility is too high in Loki?

I just posted a solution for another question that might help you for this as well on:

Way to enable vertical two-finger scrolling, but not horizontal?

I removed the libinput drivers for the touchpad and installed the synaptic drivers instead I did:

sudo apt-get remove xserver-xorg-input-libinput libinput-tools

This removes libinput touchpad driver. Then install synaptics:

sudo apt-get install xserver-xorg-input-all xserver-xorg-input-evdev xserver-xorg-input-synaptics

Then restart.

This also allowed me to change Two Finger Horizontal scrolling and add palm detection (see above link) and also made the touchpad less sensitive.

I have not tested this extensively, but seems to work so far, use at your own risk. You could always remove the synaptics packages and reinstall the libinput ones if needed.

How can I reduce the space between icons on wingpanel?

I was able to adjust mine.  Not sure if an update will affect it but now that i know where it is at i can reset it back to my liking should an update change it.

First, open files as an administrator.  Do this by right clicking files and selecting open as administrator.  Then you will have to select the root file system folder on the left hand side.  from there, here is the path to the file you will change.

usr/share/themes/elementary/gt-k3.0

The file you are going to change is named apps.css. I opened it with code by right clicking and selecting code from the "open with" selection.

NOTE: If there are lock symbols on the files and folders than you are not in as an administrator. You will not to be able to save your changes unless you are an administrator.

Once into the file, scroll most of the way down until you see:

composited-indicator {
    padding: 0 6px;
}

.composited-indicator > revealer label,
.composited-indicator > revealer image,
.composited-indicator > revealer spinner {

the line that says:

padding 0 6px;

Is the one that you will modify. Change the 6 to a 2. It should then look like:

composited-indicator {
    padding: 0 2px;
}

.composited-indicator > revealer label,
.composited-indicator > revealer image,
.composited-indicator > revealer spinner {

Once done exit and restart your system.

Elementary OS Hera not detecting my speakers

You may check this question and its answer, it may help your problem: Low Audio Volume Elementary OS 5.1.3 Hera


You should be fine! The minimum system specs are:

Intel i3 or comparable dual-core 64-bit processor
1 GB of system memory (RAM)
15 GB of disk space
Internet access

The Pentium D is 64-bit, which is the only hard processor limitation. 4GB of RAM is of course way over the minimum specs. You can always boot into the live DVD to be sure, but you should be fine.

YouTube has a video of someone installing elementary OS Loki on a Sony Vaio, and everything seemed to go pretty smoothly.


Enhancement Request: Readable Terminal Color Schema

I have yet to try this, but if one installs 'elementary tweaks' from the CLI, then navigate to 'settings -> Tweaks -> Terminal', one should be able to select a colour theme.
EDIT:
I tried out 'elementary tweaks'. Firstly, one is required to install a repository in order to access a Personal Package Archive (PPA), from which, to install 'elementary-tweaks'. Taking these first steps is at one's own discretion; the software is not part of Ubuntu's official distribution. Taking those steps, one will find the installation in 'System Settings -> Personal -> tweaks'. Clicking on 'Terminal' in the sidebar reveals options available to modify the Terminal, one of which is to change the background colour.
An alternative is Gogh, found at http://mayccoll.github.io/Gogh/ (note the hypertext protocol is not current, i.e., secure). However, it provides many colour themes to choose from and is simple to implement.
The issue you are experiencing, where there is a block of Green and text within it being difficult to read, cannot be changed to any great extent; through careful choice of theme, you should find one that has good contrast and readability.

How do I create a simple SMB file share?

You need to install samba server and make some edits in its config file:

sudo apt-get install samba samba-common

After that you have to edit the file /etc/samba/smb.conf

Just add the following (of course for requirements) to the end of the file:

[SharedFolder1]
   comment = My shared folder
   read only = yes
   path = /home/user/samba/shared_folder1
   browsable = yes
   guest ok = yes

After that you have to (re-)start the samba server:

sudo service samba restart

If the samba daemon does not automatically start on system start, type the following command:

sudo sysv-rc-conf samba on

Edit: For Loki and Juno (Ubuntu 16.04 / 18.04) the commands are:

sudo systemctl start / stop smbd for start / stop the server and sudo systemctl enable / disable smbd for autostart the daemon.

The displayed name in Windows will be "SharedFolder1".

Note: In the example above everyone has access to the folder without a password (guest ok = yes) but only in read-only mode (read-only = yes). Maybe this can also help you.

Is elementary OS performance suitable for Games and Steam?

Because this is a subjective question I’m sure you will get different opinions here (especially as it is an elementary OS User forum).  Firstly elementary is stable (I have similar specifications to you) and the drivers are supported.

I spend much of my time helping Windows user transition to Linux (specifically elementary) and there are clues in your question that you might not be ready.  Steam OS will work great with your GTX but will not play your old Windows catalogue.  Do some additional research and check out linux applications like "Wine" and "Play on Linux" to confirm your older games will play.

If there is other Windows software your rely on I also suggest you check out alternativeto.net to see if there is a Linux equivalent.  If it was not for your legacy software my suggestion would have been to jump right in especially with your programming skills.  I made the decision 9 years ago, I use elementary OS everyday and my kids use Steam on it.


How to show the debug window of Netflix in Firefox (Ctrl + Alt + Shift + D)

Ctrl + Alt + Shift + Q is working fine to me. Firefox 83 and Netflix 1080p extension.


Try running im-config in a terminal, then continue until you can select the ibus option. (this will allow to use ibus as imput method). when finished, add ibus-daemon -drx to startup applications then restart your session and you should be able to use all the configuration you have made about ibus.

i recomend you to disable the app-laucher shortcut in order to use the switching shortcut for ibus.

My eOS desktop was ruined by installing a GNOME screensaver.

Re-installed eOS and problem solved.


So after doing some research. It seems you need to upgrade the linux-firmware and the kernel.

Connect your machine to a LAN network and run the Update Manager to get the newest upgrades, or simply just upgrade these packages.

  sudo apt-get install --install-recommends linux-generic-lts-xenial
  xserver-xorg-core-lts-xenial xserver-xorg-lts-xenial
  xserver-xorg-video-all-lts-xenial xserver-xorg-input-all-lts-xenial
  libwayland-egl1-mesa-lts-xenial

Then download the newest linux-firmware

http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.157_all.deb

Install the package and restart Elementary. Hopefully that should work.


Light background for Files with dark theme

AMD driver installer not showing any text

After a little help from my friend I fixed this by:

Going to System Settings -> Languages & Region
And clicking on a popup there saying "The language pack isn't fully installed" or something similar, and installed it.
Then I applied it to login screen and all users using the button on the bottom of the screen.
Restart the system.


From what you describe, your problem is with the scaling factor of your UI. This might be due to the resolution the system is detecting.

To fix it:

Install Tweak Tool (works in elementary).

sudo apt-get install gnome-tweak-tool

Run Tweak Tool (gnome-tweak-tool).
Find the Window scaling option under "Windows".

From here, you can adjust the scaling factor, until it looks as you would expect. Be careful not to set it to too low of a value!


You need to install the relevant libraries in 32-bit.

For example, "sudo apt-get install libglu1-mesa:i386" should get rid of the "libGLU.so.1 => not found".

With some effort I'm sure you can find the packages for the other libraries.

How to delete desktop pictures in usr/share/backgrounds?

Fred,

Here is one method for changing the login screen for Elementary OS - Juno.

Save a picture of your choice in ~/Pictures
For simplicity sake, my login picture will be called Login.jpg (restricting the filename of your picture to a single word followed by .jpg makes this easier, but that is not a necessity).
open Terminal via Applications -> Terminal (or Win+T)
Type: cd /usr/share/backgrounds
Type: sudo rm elementaryos-default
NOTE: Enter your login password when prompted.
Type: sudo cp ~/Pictures/Login.jpg Login.jpg
Type: sudo ln -s Login.jpg elementaryos-default
Type: ls -al (check all folder privileges - everything should look identical)
Deleting a picture in this directory can be accomplished with sudo rm pictureName.jpg Where pictureName is replaced with the filename of what you want to delete.
Reboot

Disclaimer: Using sudo gives you carte blanche (read: total control) over your system.  Allow me to cite Ben Parker's words of wisdom:
"With great power comes great responsibility."

Good luck.

Why a whole operating system and not just a DE?

elementary develops an OS rather than just a DE for a few reasons.

elementary OS is advertised as a replacement for Windows and macOS.
Distributing elementary OS as a whole OS makes it easier to improve all aspects of the user experience (UX).
elementary is able to focus development on a single codebase.

1. A replacement for Windows and macOS
The primary target market of elementary OS is people who are not already using open source software or Linux-based OSes. It is much easier for elementary to provide a whole OS than to steer potential users to download a completely different OS and then install something on top of it, or to rely on third-party OS distributors to package up and ship (potentially modified) versions of elementary software on top of their OSes.
2. Improving all aspects of the UX
By developing and distributing elementary OS, elementary can improve more than just the "userland" (i.e. non-low-level) aspects of the user experience. For example, in the previous version, Luna, elementary OS included tweaks to the OS that made it preload frequently-used applications, making the OS and application start times faster across the board.
If, in the future, an even more low-level improvement would speed up the OS boot time, improve security, etc., elementary OS is free to make those improvements. elementary sees the user experience as starting as soon as the device powers on, not just once a user has logged in.
3. Focusing on a single codebase
elementary can focus its somewhat limited development power and resources on a single codebase: elementary OS. If elementary software was designed primarily to be used on top of other OSes, it would mean every change to the codebase would need to be tested in a variety of implementations on other OSes. It would also mean elementary would likely need to either choose a third-party OS to cater to as the reference implementation, or develop a standalone OS anyway to use as a test case.

That said, elementary definitely isn't opposed to third-parties packaging its desktop environment (Pantheon) for use elsewhere, and there are people actively doing that. :)


this sounds like a driver issue, do you know which wireless chip you have
I'll give you and update on what to do based on that

I'll know how to help you after that


Notification appearing without icon for python script

This is my first time answering something on stack exchange.
I found your post while trying to figure out the same problem.
Finally found the answer on this site http://www.devdungeon.com/content/desktop-notifications-python-libnotify

I realize you are using subprocess but i also tried it and had the same problem. The code below may need some tweaking for subprocess to work.

I initially thought that i had to somehow set the image using Gtk.Image, several googles seems to lead to that, and it came down to setting the pixbuf and then setting the icon from there. This is my first time doing a script in Python and Gtk.

Anyway, the answer from the site is below.
I followed exactly the same and managed to show my png file in the notification.

# This time import the GdkPixbuf module
from gi.repository import Notify, GdkPixbuf

Notify.init("Test App")
notification = Notify.Notification.new("Alert!")

# Use GdkPixbuf to create the proper image type
image = GdkPixbuf.Pixbuf.new_from_file("/home/NanoDano/test.png")

# Use the GdkPixbuf image
notification.set_icon_from_pixbuf(image)
notification.set_image_from_pixbuf(image)

notification.show()


elementary 6.0 (Odin) daily (20210312) cannot be installed on VirtualBox (disk disabled)

The issue was related to the fact that the disk was too small.
Probably something like 15 GB would work. I made it 20 GB and so the disk could be selected and installation continue.
Filled in this issue for tracking and solving it.


If you have Intel Graphics that was a bug and it was solved already so doing sudo apt update && sudo apt full-upgrade is going to fix it.

To check your boot time you can use systemd-analyze.
To know what is making your boot time slow, use instead systemd-analyze critical-chain. The ones that appear in red are holding up your boot.

Lastly you can use systemd-analyze plot > boot to create a file inside your home directory and check all packages involved in your boot.

NOTE: This only works on Loki or newer.


Dual boot elementary OS on SSD and Windows 10 on separate HDD?

You could simply install windows on your extra HDD. And keep booting from your SDD. Than just do sudo update-grub. To make grub detect your new windows installation. Next time your startup, you can select windows in your boot menu.


Windows 7 does not boot after installing ElementaryOS 5.1

From the linux system (Not the Live CD), try running:
sudo update-grub

You might need to manually mount the (Windows) partition before running that command, I had mixed results in the past. But 99.99% of the time, it founds the windows partition (if it's there) and add the grub entry.


System Settings > Keyboard > Shortcuts [  shortcut not working ]

You need xbindkeys and dconf-editor.
Here's your solution.


How to create a custom keyboard shortcut to center window in screen and resize to specific size

You can get the requested functionality using wmctrl. For example, the following command moves the active window to position X:400, Y:300, and resizes it to 800x500 px.
wmctrl -r :ACTIVE: -e 0,400,300,800,500

To bind it to a key, just go to Settings > Keyboard > Shortcuts and create a custom shortcut with the command.
Check the man pages for more info about wmctrl.


The automated fix as shared in below link made all the media keys work in my installation of Loki on C720.  There are a few additional fixes included, you might want to adjust the script where you find necessary.

Unfortunately your question is not clear but I will answer it as per my understanding. I guess you are installing applications with apt-get install command. To fix the issue of "the package not fully installed or deleted." You need to follow these steps.

sudo apt-get update
sudo apt-get install -f

The 2nd command should install the dependent packages that you missed in earlier installation.


I do not have an AMD graphics card installed, however I found this post that details AMD, Nvidia and Intel graphics.

How do I mount encrypted root LVM volumes for editing or recovery?

Boot using separate media such as the Elementary OS installer's
"Try Elementary OS" option
Unlock the root partition: cryptsetup luksOpen /dev/sda5 root_crypt
Verify the LVM group name - it should be 'elementary-vg': vgscan
Activate the volume: vgchange -ay elementary-vg
Mount the decrypted, activated LVM volume: mount /dev/mapper/elementary--vg-root /mnt/
Work with files as needed


How can I add / renew CA cert's which pantheon-files is using?

Get the CA which is missing. In my case:go to lets encrypt web site (or any other missing CA cert site). Copy the CA in PEM format (the format that has ----BEGIN CERTIFICATE---- in it) into /usr/local/share/ca-certificates and name it with a .crt file extension.

Then run sudo update-ca-certificates

You can verify if this worked by looking for the certificate that you just added in /etc/ssl/certs/ca-certificates.crt/


Disable search as you type in pantheon files

There isn't a way of doing this - other than installing an older version of Files.

This behaviour (i.e. only one search mode) was introduce at r2445 following bug report https://bugs.launchpad.net/pantheon-files/+bug/1604300.

However, only the first part of the intended changes have been released; the second part is still awaiting review.  The second part will fix the sorting of the search results such that the first result, selected by default, will be the same as what you would have got with the old search by typing (current folder only, starting with search term).

Hopefully this will remove any need to be able to disable the new behaviour (it is unlikely any such new options/settings would be accepted into elementaryos).


You can install pavucontrol, more informations here

The next steps work for me:

Open a terminal
type alsamixer
with the card HDA ATI SB with chip Realtek ALC892, turn auto-mute to disabled.
After that i'd install Pulse Audio Volume control.

$ sudo apt install pavucontrol

Open it Pulse Audio Volume Control
In Configuration tab you can see the ATI HDMI Digital Setereo and Internal Audio.
Select to Internal Audio: Stereo Analog Duplex (Estéreo analógico duplex).
In Pulse Audio Volume, select Ouput devices, and for Internal Analog Stereo select: analg headphones.

Important: You must have installed the ATI drivers first. D Atonaltzin

After booting from disk no wifi access appears only ethernet wired

In Terminal: nm-connection-editor. Add your new connection and also make it default: click Edit > General tab > check "Automatically connect to this network when it is available". Also, for the Ethernet connection which is present from the start: Edit > General tab > uncheck "Automatically connect to this network when it is available". Then connect to your newly added connection.


How can I find the source code that relates to keyboard settings UIs

In this case, there is a separate project in Launchpad: https://launchpad.net/switchboard-plug-keyboard.

Also of interest to anyone else starting out like I am is this google doc on building large-scale Ubuntu derivatives. The doc is here: https://docs.google.com/document/d/1RPPF14h1Sw2gQjGTuZjUIlNHnGrafS8ekhFjJM9MT00/edit

In terms of how the various components of the distro hang together - they each are packaged and built individually, the main build distro simply has a pointer to each package. So you could remove the package from the distro by removing a line of code. A user could then install the package separately themselves (please someone correct me if I have this wrong).


How to disable built-in wifi and use only USB wifi card?

We can simply blacklist the modules which we do not want to use.
To blacklist the module of your wireless card :

1. sudo vi /etc/modprobe.d/blacklist.conf (If you can not find it you can create one).

2. Comment the module name with a # in the beginning of the line:

#blacklist wlan0
3. Save, run sudo update-initramfs -u and reboot
To remove a module manually without rebooting :

sudo modprobe -r wlan0

Looses effect after reboot.

To load the module again:

sudo modprobe wlan0

To check the modules were loaded or not :

sudo lsmod

I found the answer from here. This worked for me, however if you have other problem regarding this you can check the link. It has tons of answer.

Apple Airpods Bluetooth Paring not working

I may add to your problem, since it seems like bluetooth in general is crap for me. Airpods never work, but also my ps4 controller, and many other devices that normally should connect seemlessly on any other desktop.


Only a quarter of the screen is shown during elementary OS installation

There are many issues with this model, but you may complete the install process by using the live option.

Create a bootable usb drive using Unetbootin.
Boot into the usb flash drive.
Select the live option: "Try Elementary OS without installing".
Select the install icon from the dock and complete the install process.


Cannot find indicator-synapse config file

I do searches differently, perhaps run "sudo updatedb" then follow with "sudo locate config.json"
This should locate the file if it was generated.


Thanks to Paul, I was able to find the setting to use the "Classic Theme":

Unfortunately, my OCD could not handle the slight difference shown between the title bar and the tab bar in the screenshot above.

That's when I installed the Freya Theme for Google:

I prefer this one because it is perfect.

I could link to this, but I need at least 10 repuation to post more than 2 links, and I am the worst.


As in, I have to authenticate every single system action. Mounting
  drives, updating repositories in appcenter, etc, all need another
  entry of my password

That is normal or seems to me. Let's say you want to update the repositories, you opened up Terminal(terminal) then executed sudo apt update and its for your password! Why? Because you used sudo which is gives you super user privilege(root). And if you perform another sudo task right after it usually won't ask for password. The whole 'security' in Linux distributions have been taken seriously so, this is okay and this is how it's good.

If you want to login as root and do stuff, execute sudo su.


Responsiveness delay in menu, most apps and right clicking

Solved it. Well, basically with some tough love.

I purged a LOT (but not critical stuff) of my ~./config and ~./local directories and I also purged my ~./mozilla directory. My gut tells me the culprit was a combination of the group of these configs.

Some things to note - I use a dedicated home partition. So this means when I did a clean install using the same dedicated home, the problem persisted.

After cleaning out what I described above (and understanding what data would be gone and what would not), things worked just fine.


How can I get rid of "The update information is outdated." warning?

Using one or more PPAs that don't work might cause this problem sometimes. Run

sudo apt-get update

to check which PPAs are causing the error and remove them if necessary.


That's most likely because for better or worse, Elementary/Pantheon defaults to hiding indicators that haven't been whitelisted.

You can correct this issue, and get indicator functionality back in general by following these instructions on GitHub. Basically install this package and then reboot.

No WIFI on Initial Installation - VERY Novice User

I was sitting around refreshing this page waiting for an answer and then I was just like well why don’t I just go ahead and try the possible solution I mapped out? So I downloaded a newer firmware from that location, fired up Elementary, opened terminal, navigated to a folder where I had placed the .deb file* and then entered the sudo command. Something... happened, which looked promising. I rebooted and wifi worked!
Just answering this in case another novice user has this problem, or so that someone who knows that they’re doing can come on and scold me for doing something silly!

This is probably not necessary context for most users of this forum but as a terminal newbie I’m always confused when people are just like “enter whatever”


are you running a spinning disk or SSD ?

normally when a machine comes back from sleep (hibernation) it needs to read all the data that was saved to disk before you can have any KB input or the system works properly.

this same happens on PC and MAC if they go into hibernation.

hibernation is different to lets say screen off for example.

are able to provide more information on your setup specifically the HDD type and computer brand, MB type etc could also help.

are you using provider supplied drivers?

i would also recommend turning off "suspend" mode.

applications > power > suspend > never.

personally i'm not seeing this issue running with a VMware fusion VM.

for me the system suspends and then returns straight away.

this could come down to the standardised drivers for virtual machines etc + on SSD drive.

hopefully i can be of more assistance with additional info.

If I do a direct connection to my HP Officejet Pro L7590 via USB, the printer is immediately recognized as a scanner as well. So, contrary to HP's own documentation, this seems to be a limitation of libsane-hpaio when trying to use over a wired network. This is the only way I have managed to get this to work.


I'm not sure why I had to do this but I manually edited dconf to set the font. You can use the dconf-editor utility from that same package, or:
dconf write /io/elementary/terminal/settings/font '"Roboto Mono for Powerline 10"'

And yes, you need the strange double quoting, it uses GVariant format so it needs strings formatted like this.
My understanding was that fonts-powerline patched the fonts, but this works so I'm going to stop pursuing ghosts.


I would suggest that you look at the apt command
this should probably be used as "sudo apt install {the application}"

Launching a command in terminal from the app launcher

I've tried writing a script, changing the output, etc but the problem is (I believe) on elementary's terminal not waiting the command to end

Because I've changed the command using cat instead of curl (to test that thought), having curl output the website to a temp text, and got the same result with the command prompt

Also haven't tried another terminal to compare results

The solution I see could fit as a probable solution, is to write code in C, Python or w/e language you want...compile it and run it.

UPDATE

I've made my first Vala app just for this :P , I modified an example code with my knowledge of other languages and worked

https://github.com/rscm/wttr/blob/master/wttr

Just download the file and it will load the default url wttr.in in a webview. If you call the file with and argument like bydgoszcz will load that location. I didn't validate any input so don't send weird stuff

Summary:

./wttr is the same as curl wttr.in
./wttr bydgoszcz is the same as curl wttr.in/bydgoszcz

Tomorrow I'll upload the code in the repo if you want to modify it


How do I remove copy/paste touchpad controls from elementary OS Loki?

I also used the xmodmap solution, but this disables the middle mouse completely.
Another solution is installing the gnome-tweak-tool from the AppCenter and disabling Middle-click Paste:
https://askubuntu.com/a/872165/519324

I opened an issue for this. As of elementary OS 5 and 5.1, it has been resolved and there is now a toggle in System Settings → Mouse & Touchpad → Clicking called Middle click paste that can enable or disable this behavior.


driver update selection in new AppCenter - do I need two nvidia drivers (340 375)?

No, you don't need to and, in fact, you can't have multiple versions of a driver installed. You have an option to install other versions because the newest drivers do not always work best.

If you run into any problems with nvidia drivers you can install older versions and see how they work. A currently installed version will be replaced automatically.


Is it possible to uninstall the desktop?

If You Need a Server OS

It is possible to fully uninstall the GUI from the Terminal, but please be aware the elementary OS is not a server-targeted OS. If you need a server OS, I recommend Ubuntu Server. You'll get the same Debian/Ubuntu underpinnings tailored to a server environment. This is much better than trying to work backwards from a desktop-focused OS.

If You Need a TTY Temporarily

If you just need to access a full-screen Terminal without any GUI, you can switch to another TTY with the keyboard shortcut ctrl+alt/option+Fn where n is a number 1-6.

If You Really Are Sure You Want to Uninstall The GUI (Don't Do This)

Please be sure you really really really want to do this. This is probably a bad idea. It might be hard to recover. If you're 100% sure, open up a Terminal and enter the following:

sudo apt-get remove xserver-xorg

That should uninstall the X server (the thing that lets us display graphics). Please don't do this unless you are 100% sure this is what you want.


You can try to use QuickTile for this kind of thing.

afaik eOS doesn't have native support for this. There's a bounty for it here, as well.


A relevant issue on a similar topic, the middle mouse button:
https://github.com/elementary/default-settings/issues/5

You might want to start a discussion on whether this is expected behavior.

Snap run Spotify generating endless errors inside terminal

Looks like some other people are having this same issue with Google Chrome. This answer worked for one user:
https://unix.stackexchange.com/questions/473115/google-chrome-gpu-driver-issues-on-ubuntu-18-04


Spotify opens a new window when you click on the sound tray menu [Loki]

This application acts against common expectations, so I'd consider it a bug. Please subscribe to the bug report here so that the devs can ask for help testing solutions. If you want to give the open source devs some extra incentive, try putting a developer bounty on the task.


The short answer is yes, a GTK# application would be accepted into the AppCenter repositories assuming it met the rest of the review process (basically that it doesn't do anything questionably legal or mess with the system).

The other thing to be aware of is that it must be a GTK 3 interface, not GTK 2. I'm pretty sure that'll be the case by default with GTK# though.

However, the part where you're possibly making life more difficult for yourself is the fact that I don't think I've seen any C#/Mono/GTK# apps in the AppCenter yet, so there won't be any handy examples of how to set up your build tools and packaging files so that Houston (the build/testing server for AppCenter) can automatically build, test and publish your app.

It's not an insurmountable problem, I'm sure someone somewhere has packaged a GTK# application for debian based distros before, but you're less likely to get quick help and support as it's something that the elementary team will be more unfamiliar with.

Have you had a look at Vala (the language used for elementary OS itself and the included apps)? The syntax is incredibly similar to C# and you could consider tools like Glade or the nightly builds of GNOME builder via flatpak (that now include built in Glade) to design UIs. That said, I'd recommend at least trying to build UIs in code without a designer as it teaches you how things interact much quicker.

Hope that helps! Good luck with your app development, I hope to see some of your apps in the store in the future!

How do I download/install driver for HP Officejet 4655

You can find a similar question here. Have a look at sugestion 4. In the approved answer.


Wired will be turned off until you connect some network cable, or USB with a phone with thetering mode enabled.  If there is no wired network connected the "Advanced settings" will be disabled also because it is only for wired networks, so unless you have connected a network cable(or usb thetering device) they will remain disabled.

When you open the Network Properties box the first cathegory selected (look at the Devices list on left) is the Wired. Below Wired  should be a Wireless option, select it and you will see the available wi-fi networks.

Breadcrumbs bar in file dialog not working

There are known regressions/issues with the filechooser breadcrumbs.  See https://github.com/elementary/files/issues/1226 which matches your problem I think.  This will not be fixed in the next release - which is imminent but https://github.com/elementary/files/pull/1136 will be fixed.

Hopefully your issue will be fixed in the following release in about a months time.

A work around is to use the keyboard shortcut UpArrow to navigate to the parent directory.


PhpStorm: Dead keys not working (for ', ", etc)

I was able to fix this issue by executing ibus-setup in a terminal.

Source:
https://askubuntu.com/questions/774237/dead-keys-accents-stopped-working-after-upgrading-to-ubuntu-16-04

To fix it permanently you need to figure out how to start ibus-deamon on system startup (I haven't quite figured that one out yet).


I've had this happen to me a couple of times. Usually when I've been manually configuring partitions and made a mistake somewhere.

ls in grub will show you all the partitions on each hard drive that grub can find.

If you think you know what the boot partition is for elementary OS e.g (hd0, gpt4) then you can boot by telling grub where to load it's configfile:

configfile (hd0, gpt4)/boot/grub/grub.cfg

Maybe someone else can chime in about how to boot Windows.


Light terminal-based alternative to gdebi

After installing gedit text editor, in order to associate the deb files with an "application":

gedit ~/.local/share/applications/deb_install.desktop

with the lines:

[Desktop Entry]
Type=Application
Name=[Desktop Entry]
Icon=gdebi
MimeType=application/vnd.debian.binary-package;
Exec=pantheon-terminal -e "sudo dpkg -i %f"

Then, right click a deb file, select "Open with" - "Other application", and select "Install deb".


Apt repo add with human error, empty AppCenter

Open Files as administrator (Right click on the icon> New Window as Admin) and navigate to /etc/apt/ . Check the file sources.list and compare with this one. If it has the same entries then it's fine.

If the folder sources.list exist, delete it. Make sure you are deleting the folder and not the file with the same name!

Now go to the folder sources.list.d and check that you have a file called syncthing.list. If you do, then all good. Otherwise you'd need to execute again

echo "deb https://apt.syncthing.net/ syncthing stable" | sudo tee /etc/apt/sources.list.d/syncthing.list

Everything is back to normal now. If you don't get new updates it's because there aren't any


How to get my computer to turn off when the lid is closed

You can set your computer to shut down if you close the lid (and this separately for Plugged in and On Battery modes).

However I don't really understand how can you not have to restart the computer the next time you want to use it: if you power it off, you will have to power it on eventually if you want to use it again…

Unlock Settings / Power and set Shutdown as lid close action.

technicallyblue,

Welcome to the forum.  Ken Kinder's comment was spot on the mark.  I am running VBox  5.2.18_Ubuntu r123745 (with extension pack) on Juno -- no problems (so far).

However, your stated POSIX permissions on your /usr directory you stated were (751).  From the directory listing you gave they appear to be (777).  That does not match my fresh installation of Juno.

Performing a chmod on the entire /usr directory is not recommended.  I highly urge you to reset it to 755 as soon as possible. That command would be:

sudo chmod -R 755 /usr

You have already set the /usr and /usr/lib folder owner to root (which is the correct user).  After the chmod command has finished, I recommend a reboot.  After the reboot, completely uninstall virtualbox and all of its settings with the following command:

sudo apt purge virtualbox

Then you can reinstall Virtualbox the usual way (AppCenter or sudo apt install virtualbox).  Good luck!  If you continue to experience odd problems, it may be necessary to reinstall Juno.  However, don't jump through those hoops unless you are forced to do so...


I don't know if it is safe to update genetic kernel to 4.8

Side note: I also had a PC with a BIOS that did not allow booting from a USB. I downloaded PLOP boot manager, burned it to disc, booted from it, and was then able to access the the USB drive to boot from it.

Shortcut to change the pantheon-terminal font size

Shift +  Ctrl + + for increasing
Ctrl + - for decreasing font size.


So the hidpoint suggestion sent me on an oddessy of trying to install 32bit libraries to run it's xWindows install. BLEH.

I installed Solaar instead and the problem with my mouse buttons was resolved. I get the added benefit of seeing information about the unifying receiver in a graphic interface.

From your terminal

sudo apt-get update

sudo apt-get install solaar

I hope this provides you a better working solution.


Good news! I fixed this problem!

In the just moment, I had tried many ways to recover my OS including download other shells(I downloaded Gnome shell,actually, It doesn't work) and enter the recovery model when the OS start(It often locates under the item of OS and has two or more models).
Of course, the latter method worked, when you enter the recovery model you should select the 'dpkg' item and it seems only in this item you have write permission.  Before you modify some files the OS will ask one or two questions(Just input 'Yes'), then you can operate the OS as super user.

What I need to do is that

vi /etc/passwd

and change mine default bash to

/bin/bash

You should find your own username(It often in the end of the file).

At this time, this crash had been fixed. Just log out the recovery model and reboot.

Have fun with your recovery OS!

How to repair the system after an accidental deletion of the kernels?

sudo update-grub

Should fix your booting issue and:

sudo apt-get autoremove

Should remove older kernels and packages that are no longer used and free up some disk space.
Future updates will replace whatever it was you deleted but if your still having issues then:

sudo apt-get --fix-broken install


elementaryOS 5.1.7 Hera AppCenter and apt require password to install anything

There's a lot of content in this "question" so it's hard to fully understand what you're asking. It's often better to ask a succinct question if you want a succint answer, but I'll try and answer some of your points.
In summary, if you have forgotten your password, it's not just installing software you're going to struggle with. Changing certain settings will require a password. Unless you've enabled autologon, you'll need your password to log onto the system and unlock it. And if you have enabled autologon, you will be prompted for your password more frequently as a security measure.
In case it wasn't clear, the password you are being prompted for is the password you set when you installed elementary OS. This is the same password you log into the system with (unless you have enabled autologon).
Now, onto some of your other points:

in Files (app), right-click on the .deb file and select "open in AppCenter" : that option wasn't present, so I added it

This option intentionally doesn't exist since AppCenter does not support installing .deb files. So it's expected that it would do nothing.

AppCenter : Firefox, Fondo, Norka for example and all went nicely and requesting NO password

AppCenter generally prompts for a password for installing new applications. Installing new software onto a computer always carries some small amount of risk, so this acts as a confirmation that you have permission to do this on the computer and have thought about the implications. There are some specific circumstances where AppCenter won't prompt for a password for new installations, these are:

You have already recently given a correct password to AppCenter, it won't prompt again for a period of time.
You are installing a Flatpak application (e.g. from flathub.org). If you have installed an application from there in the past, other applications from Flathub will be available in AppCenter. These applications are considered slightly more secure, and are often only installed for your user account rather than all users on the system, so we don't prompt for a password here.

I read that elementary OS has in-built the "no-password required" concept to install stuff in order to avoid "authentication-fatigue" as they say

If you have read that there is no password required to install software somewhere, please inform the author of that source that this is incorrect. This is correct for updating software as updating software is usually better than not updating software from a security perspective, but installing new software will always require a password except in the cases mentioned above.
So to answer your question of how to install a .deb file, you are correct that you either need an application like Eddy (preferred) or Synaptic, or you can use the command line sudo apt install ./debfile.deb. However, all of these methods will require a password as installing a .deb file requires administrator permissions.

Eddy shows $5, so not Free, contrary to one answer

Any applications showing a price in AppCenter follow the elementary "pay what you want" model. The $5 is the price the developer has suggested they feel their application is worth. You can choose to pay any amount for it (including $0) if you wish.


2009 MacBook Pro running elementary OS Freya freezes shortly after waking from sleep mode

I think I may have found a solution to my problem, so I wanted to post the solution here in case anyone else is having the same freezing issues.

I found a similar post I made on a Deb forum over a year ago and the solution was given to me by user kc1di:

Try the nouveau.noaccel=1 parameter - hit tab at the boot command and the e type in:

nouveau.noaccel=1

after the kernel line that has quiet in it.

If that works for you you can make it permanent by editing the /etc/default/grub file. and making it look like this:

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet nouveau.noaccel=1"
GRUB_CMDLINE_LINUX=""

I tried this with elementary OS and all seems well.  The graphics when an application opens aren't as smooth/clean looking as before, but I've put my computer to sleep, woken it up, opened various apps many times now and it never seems to freeze anymore.  So far so good!

If at the time of creating folders with names in you native language the old ones weren't empty then you will end up with both of them. As far as I remember there is an info about it in dialog asking about creating the ones in your native language.


How do I move the dock to the right of screen on loki?

You can get the plank preferences by doing either Ctrl+right-click on the plank, or from a command line  plank --preferences.


You need some user account with root priviledges to assign root priviledges to your own account.

To check if you have any such account on your computer you can either check:

a) Switchboard > User accounts

b) checking the content of sudoers file in /etc/sudoers. However I see no way of checking it without sudo other than booting from liveCD and opening it from there.

This is not exactly an answer and should have been a comment. However I don't have enough reputation points to comment your question so I've been forced to polute it with fake answer. Thanks for understanding.


You can change the default shortcut editing the dconf. For example, to set it to Ctrl+Alt+L you can type:

gsettings set org.gnome.settings-daemon.plugins.media-keys screensaver "<Ctrl><Alt>l"


How to automatically disable touchpad when USB mouse connected

Edit - This works in Freya NOT Loki

Here is my solution for disabling the touchpad in elementary OS when attaching a USB mouse.

I created these instructions based on the following websites:
https://bbs.archlinux.org/viewtopic.php?id=188918

https://bbs.archlinux.org/viewtopic.php?id=170396

As well as the arch wiki on Synaptics touchpad, but I'm only allowed to paste 2 links.

Open a terminal by pressing the key combination: Super + T or by opening it from the Applications menu

Enter the following at the prompt to open Scratch as root:

sudo scratch-text-editor

Enter your password when asked.

Create a new file.

Paste the following into the new file:

SUBSYSTEM=="input", KERNEL=="mouse[0-9]*", ACTION=="add", ENV{DISPLAY}=":0", ENV{XAUTHORITY}="/home/$USERNAME$/.Xauthority", RUN+="/bin/sh -c '/usr/bin/synclient TouchpadOff=1; sleep 5; /usr/bin/killall -q syndaemon'"
SUBSYSTEM=="input", KERNEL=="mouse[0-9]*", ACTION=="remove", ENV{DISPLAY}=":0", ENV{XAUTHORITY}="/home/$USERNAME$/.Xauthority", RUN+="/bin/sh -c '/usr/bin/synclient TouchpadOff=0'"

* Replace $USERNAME$ in these 2 lines with your actual username. *

Click the save button
Click “Computer” in the left hand column of the dialogue box.
Navigate to the /etc/udev/rules.d folder
Type the name “01-touchpad.rules” as the name of the file and click Save
Close the file

This alone should enable and disable the touchpad when attaching or detaching a USB mouse.  This will not disable the touchpad at system startup if a USB mouse is attached.  To do this you can do the following:

Open a terminal
Enter the following at the prompt to open Scratch as root:

sudo scratch-text-editor

Enter your password when asked.

Create a new file and paste the following into it:

#!/bin/bash
lista=`xinput list | grep -i 'mouse'`
listb=`xinput list | grep -i 'transceiver' | grep -i 'pointer'`
listc=`xinput list | grep -i 'receiver' | grep -i 'pointer'`

if [ ${#lista} -eq 0 ] && [ ${#listb} -eq 0 ] && [ ${#listc} -eq 0 ]; then
    exec `synclient TouchpadOff=0`
    notify-send "No USB Mouse Detected" "Your Touchpad is Active"
else
    exec  `synclient TouchpadOff=1`
    notify-send "USB Mouse Detected" "Your Touchpad is Disabled"
    sleep 5
    killall -q syndaemon
fi

Click the Save button
Click "Computer" in the left column then navigate to /usr/local/bin
Type the name "mouse_detect.sh" for the filename and click Save

Open the "Files" application as an Administrator
If it is on your Plank, right click to find this option.  If it is not, then open "Files" from the application menu and right-click the icon on Plank when it opens to find the option.
Enter your password when asked.

Click "File System" in the left column and navigate to /usr/local/bin.  Your file "mouse_detect.sh" should be present.  Right click on this file and select "Properties"
Click on the "More" button and then click on each of the "Execute" buttons to ensure they are all highlighted.
Close Files

Now we need to create an autostart entry
Open "System Settings" and click "Applications"
Click "Startup" and click the "+" button in the lower left hand corner.
When the box opens up type "/usr/local/bin/mouse_detect.sh" in the lower box where it asks you to type a custom command.

Open "Files" and press CTRL-H to display hidden files and press Home in the left hand column
Navigate to the ~/.config/autostart

You should see a file like "custom-command0.desktop", open this in "Scratch" by right clicking and selecting Open With. (select Other Application if necessary)
You should see a line that says Exec=/usr/local/bin/mouse_detect.sh if you are in the right file
Add the following line line to the file:

X-GNOME-Autostart-Delay=8

You can also enter a custom name for the desktop file in the "Name" field and a custom comment in the "Comment" field.
Note: I had to remove the [en_CA] from my Name[en_CA] field for the name change to be visible in "Files".  You might have to do the same if you live outside the US.

If you go back to your startup applications, your custom Name and Comment should be visible and you can enable or disable the autorun of this script on startup by clicking on the toggle to the right of it.

That should do it.  If the startup script detects other wireless devices as a mouse and disables your touchpad when it shouldn't you can try changing the contents of the mouse_detect.sh file to:

#!/bin/bash
lista=`xinput list | grep -i 'mouse'`

if [ ${#lista} -eq 0 ]; then
    exec `synclient TouchpadOff=0`
    notify-send "No USB Mouse Detected" "Your Touchpad is Active"
else
    exec  `synclient TouchpadOff=1`
    notify-send "USB Mouse Detected" "Your Touchpad is Disabled"
    sleep 5
    killall -q syndaemon
fi

This has less chance of detecting wireless mice though, so only use it if the first one does not work for you.

Cannot install angular on elementary os!

From https://www.npmjs.com/package/@angular/cli#installation

Install Globablly
npm install -g @angular/cli
Install Locally
npm install @angular/cli

In Linux, every time you install something, when that something is Global means you need root access and when something is Local just with your user is enough

To translate that into commands
Global
sudo npm install -g @angular/cli
Local
npm install @angular/cli

Permission Denied
You can see what is the problem clearly in the log
npm ERR! Error: EACCES: permission denied, access '/usr/local/lib'

Probably the installer wants to write there but can's because only the root user can

You can install a newer version of Brasero from the GNOME3 Staging PPA. It works fine without errors.

In a terminal, type:

sudo apt-add-repository ppa:gnome3-team/gnome3-staging
sudo apt-get update
sudo apt-get install brasero
sudo add-apt-repository --remove ppa:gnome3-team/gnome3-staging

Please note that you won't be able to receive any new updates to Brasero after you install it. Also, doing an upgrade between these commands is not recommended and could lead to serious problems with your system (and possibly even break it).

Installing Elementary OS without USB drive or DVD

The only option that comes to my mind is using the UNetbootin Hard Disk Install Mode. You can find the details here on UNetbootin Sourceforge page. I would also refer you to this AskUbuntu question for step by step process.

I think the hard disk here can be an empty partition on hard disk on the mac book or a new partition on your external usb installation, if you don't want to mess with your mac book hard disk.

Latest UNetbootin can be installed via following commands,

sudo add-apt-repository ppa:gezakovacs/ppa
sudo apt-get update
sudo apt-get install unetbootin

Unable to boot to elementary OS from USB - macOS High Sierra

This may not be a traditional "I fixed it" answer, but it did solve the issue.

in macOS, go to the Apple App Store
Install Parallels Lite (It's free)
Install all the Linux distros you want. Including elementary OS. It works great.

Done.

After almost a week working on this issue... Parallels was a great 12 minute solution.

UberWriter does not support Ubuntu 16.04 (upon which elementary is based), thus the command to add the PPA fails.

From inside the project directory, install UberWriter with sudo python setup.py install.

Stuck on splash screen at boot on Acer Aspire E15

Here is the Solution:

Because you already installed elementary OS only the second step is important for you.

When you boot the live system, move your selection to 'Try elementary OS without installing', then press 'E' on your keyboard (for editing the boot options).
Move the cursor to the line where it says "Linux ....... splash screen" at the end of the line insert a space and then write 'modprobe.blacklist=dw_dmac,dw_dmac_core'.
Hit F10 for booting. Now install elementary OS and reboot.
Turn on your notebook and do all the updates (sudo apt-get update && sudo apt-get upgrade).
Next open a terminal and write 'sudo nano /etc/default/grub', go to the line where it says 'GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"' and change it to 'GRUB_CMDLINE_LINUX_DEFAULT="quiet splash modprobe.blacklist=dw_dmac,dw_dmac_core"'. On your keyboard press 'Control + X', then 'Y' and 'Enter' to save and exit. Now write 'sudo update-grub' in the terminal.

Reboot and you should be done!


How does one cycle through windows of the same application?

Edit: This is not the correct answer for the above question. When i wrote this i was thinking about tabs of an application and not windows. So, this answer works for cycling through tabs of an app.

Ctrl + PgUp/PgDn is the default keyboard shortcut to cycle through windows/tabs in an application.

In some applications if Ctrl + PgUp/PgDn doesn't work, try Ctrl + Shift + PgUp/PgDn

Here is a list of keyboard shortcuts in elementary: elementary os keyboard shortcuts

You can also refer to the answer to this question here, which is similar to yours.

Keyboard backlight is not working on Lenovo U330

Not sure about the U330, but it works fine on my Lenovo U31 running elementary OS 0.3.1 and prior to the 0.3.1 update. I think it is the F9 key that enables it on the U330. If you have Hotkey mode disabled in BIOS, you need to press Fn + F9 to turn on the backlight.

http://www.lenovo.com/shop/americas/content/user_guides/u330p_u430p_ug_english.pdf

"Note:If you changed the HotKey Mode from Enabled to Disabled
 in the BIOS setup utility, you will need to press the Fn key in combination with the appropriate hotkey"


I had the same problem I just use the menu key to get out of the hand cursor with the + sign I know it's not the best solution but it works for me .

Zoom (seminar software) keeps hanging (Elementary Hera)

The issue is indeed related to the kernel updates, and affects the Intel HD graphics card driver. There's a fix in the next kernel release (5.30-52): https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872001

The alternative is to roll back to 5.30-45 (https://www.reddit.com/r/linuxmint/comments/g9vxce/zoom_freezing_in_linux_kernel_greater_than_53045/)

To verify if you're affected by this, run journalctl -b | grep i915, and look for lines that say Resetting rcs0 for hang on rcs0 around the same time that you're attempting to use Zoom.

Volume of system gets muted automatically

Sounds to me like you need to check your headphone's volume settings.

Plug in your headphones.
Open the terminal, and run alsamixer. You will get something like this:

[

From here, find the option labelled "Headphones" and, if it reads "MM", press "M" to unmute them. You may also need to raise their volume by pressing the up arrow.

For good measure, ensure that automute is enabled as well (it most likely is, but still double check).


not sure if this is the same situation ... especially since I am trying to remember exactly what happened to me ...
First thing first ... I was running ubuntu at work ... ran a software update ... then all of a sudden i didnt have any network.

To get the network running (I need that for work) What I did was manually edit /etc/network/interfaces and configured it for my static IP address ...
it is not very complicated

auto eth0
iface eth0 inet static
address {your IP address here}
gateway {your ...}
netmask {your ...}
dns-nameservers {your ...} {... if multiple}

I think that was all I needed

after another software update (I think there was something "funky" about a Network Manager update) I was able to put it back that way it was and the network was working
the way it was/is

auto lo
iface lo inet loopback

see it that helps you out or at least points you to a solution that works for you ...


How to replace just close minimize window icons?

Copy the elementary theme and replace the icon files and set it as a new theme.

Edit:

Sorry i was on my iPod so i couldn't really tell you in all details.

Copy the elementary theme from /usr/share/icons/ to documents.

  [Icon Theme] Name=elementary

To

  [Icon Theme] Name=elementaryNewTheme

Change the folder to the same name.
Get the icons you would like to replace and replace the ones in the "elementaryNewTheme" folder. (you can use the search option of pantheon-files to make it easier)
Open pantheon with administrator (right click at the dock -> new window as admin)
now copy the "elementaryNewTheme" from /home/yourUserName/Documents/ to /usr/share/icons/
use elementary tweaks to change the icon pack to "elementaryNewTheme"
should do the trick.

Is it possible to swap the Alt keys of a MacBook keyboard?

You can use xmodmap for that. First find out the keycode(s) of the alt keys using "xev". If not installed, you should install the x11-utils package. So type

$ xev | grep keycode

in terminal, focus to the small window by clicking on it and look to the output in terminal.

Now press the ALT key(s).  You will see the keycode of the key and its name (e.g. keycode 64 and ALT_L for the left ALT key). Remember the displayed code and name. Let's assume that ALT-L has code 64 and ALT-R code 77. Now type in terminal:

$ xmodmap -e "keycode 77 = Alt_L"
$ xmodmap -e "keycode 64 = ALT_R"

Note: I don't know the "real name" for right Alt key, so the name in  second command will probably not be correct.

Now the behaviour of the keys should be changed. Try it.
This will only work until next reboot. If you want to make it permanently, you can add the two last commands to your ~/.bashrc.

Maybe it is not the simplest way, but it should work.


Where can I find the maximize icon file?

I know what you are looking for is another type of icons but I really don't know where to look. I tried to find them but nothing.

I messed up with usr/share/fonts, please help

Run these commands in a terminal will reverse the permission changes:
cd /usr/share/fonts
sudo find -type d -name '*' -exec chmod 755 {} \;
sudo find -type f -name '*' -exec chmod 644 {} \;
The first command makes sure you are in the right folder.
The second command changes the permissions of all the folders.
The third command changes the permissions of all the files.
I strongly suggest you backup the usr/share/fonts folder to safe place before attempting to changes it. I also strongly suggest you first run the second two commands without the -exec ..... part.  It will then just list the regular files that will be changed to the terminal and you can double check it is going to change the right ones.


To the first question, you can open a terminal and type:

killall appcenter

Now the reminder dessapears from Planck.

To the second question, you can try to show all the hidden startup applications. Open a terminal and type:

sudo sed -i 's/NoDisplay=true/NoDisplay=false/g' /etc/xdg/autostart/*.desktop

Then launch the Gnome session properties from terminal:

gnome-session-properties

Look for the appcenter launcher and uncheck it. It called:

appcenter -s

Update: I ultimately ended up installing Ubuntu, but I believe the steps I used to fix the problem would also work for elementary OS. Be sure to back up your data for the unlikely event that something goes wrong while doing these steps.
It's been a while since I've completed the steps, so follow these instructions at your own risk.
First, I used the "Intel Optane Memory and Storage Management" application to disable Intel Optane Memory system acceleration and reboot. (Forgetting this step will cause Windows to enter "automatic repair" mode on boot in AHCI mode.)
Then, launch msconfig and enable minimal Safe Mode on the boot tab.
Then boot into the BIOS configuration and set the SATA hard disk operation mode to AHCI mode.
Reboot (into safe mode), and then launch msconfig again, and disable Safe Mode on the boot tab.
Reboot one last time. Your Windows system should function as normal. At this point you can resume the normal process of installing elementary OS/Ubuntu, including resizing partitions, etc.
Note 1: I personally have not noticed a reduction in Windows speed from disabling the memory acceleration and switching the SATA operation mode from RAID to AHCI.
Note 2: If Windows has a problem booting, try temporarily switching the SATA operation mode back to RAID.
(Reference for switching Windows to AHCI mode: https://superuser.com/a/1359471).


Install elementary OS in dual boot with 'something else' option

Note : This can also be used to reinstall elementary OS. To reinstall skip the partition steps.

Partitoning :
Before using something else option allocate space to install elementary OS.
Open Gparted then select partiton you want to allocate for elementary OS.
Right click --> Delete.
Step1: Now right click on the partition --> New --> extended partition. and ext4 File system.

Step2 : Make Partitions for swap, /root and /home.
Now Right click on the /sda2 and select Resize/Move
Here -- sda2  extended
   sda5 format swap -
   sda6 format ext4 -
   sda7 format ext4 -

Note:

You can choose swap  size same as size of your RAM. Generally 4GB swap is enough.

20 GiB is enough for /root.
See system specifications, at least 15 GB of disk space needed.

/home is the filesystem for your user's files: documents, images, music and videos

Now your partition table similar to like this:

Installation:
Now start installing and then select something else option.

Now,
select /sda5 --> click on change button (at left corner) you will see popup like this:

Now click on drop down button select swap area.

Similarly for /sda6 and /sda7 select ext4 / and ext4 /home respectively.
Now click on Install Now


System Settings for Sound and Color are freezing

There is a change that's caused by the German translation.
I would recommend testing this again in the English language,

I now understand that the settings still freezed in english, so it's not a translation issue. I would recommend starting the System Settings from the terminal with debug enabled:

$ switchboard --debug

Hopefully that shows useful errors. You could then include that in your question and open issues in the specific switchboard plug repositories. (Switchboard is the System Settings application, every "page" is a "plug")

I would recommend starting with the sound plug, since that one is build and maintained by elementary OS.
Sound plug repository: https://github.com/elementary/switchboard-plug-sound

I'm actually not sure where the code lives for that color plug, seems like it's older, not following the regular elementary OS visual style. Maybe other people know more.

Update: I understand from Adam Bieńkowski that the color plug is part of the GNOME control center.
I think that code lives here: https://github.com/GNOME/gnome-control-center
And issues should probably be reported here: https://bugzilla.gnome.org
Probably to the project "gnome-control-center" and the component "Color":
https://bugzilla.gnome.org/buglist.cgi?quicksearch=component%3AColor%20product%3A%22gnome-control-center%22%20
(Damn that site makes me so happy elementary OS is on Github)

Update 2: This sounds a bit like: https://github.com/elementary/switchboard/issues/53


How to set wifi driver settings to prefer 5 GHz channel over 2.4 GHz

Run lshw -class network. Look at the logical name for your wireless card. Let that be denoted <wlan>. CD into a relevant directory, store your current wireless config: iwconfig <wlan> > current_wireless_config to restore settings later if need be.

Post the output to iwlist <wlan> channel here. You may wish to follow the advice in this answer: https://askubuntu.com/a/55748 or you may download linSSID from the app center and find a good open channel and frequency and set it as follows.

Turn your wifi off, then run:

sudo iwconfig <wlan> mode Managed
sudo iwconfig <wlan> freq <desired-freq>
sudo iwconfig <wlan> channel <desired-channel>

Make sure this is in agreement with your output from iwlist <wlan> scan or iwlist <wlan> channel and the frequency matches the corresponding channel. Reboot computer.

WARNING: According to man iwconfig under "freq/channel":

  When  using  Managed mode, most often the Access Point dictates the
  channel and the driver may refuse the setting of the frequency.

As per your discussion on askubuntu, Managed mode may be the best option you have. So try just that without changing the frequency or channel parameters and see how it goes.

Other parameters of your wireless interface may also be the culprit for your connectivity issues. To be sure, post the output to iwconfig <wlan> in your question.


How to delete Google Calendars in Maya (Loki 0.4)?

You can hover over the calendar name in the gear menu (top right) and a trash icon appears. However, there are two special system calendars (Birthdays&Anniversaries / Personal) that you cannot delete but  hide.


You have to install the package ibus-qt4.


As far as I know, it is possible to disable only magazines but it requires a lot more hacks.

The better choice is to use synaptic.

Installation:

Open terminal and run-

sudo apt-get install synaptic
