UserLAnd/Debian Linux

Here is an update on my testing with UserLAnd on a Galaxy Note8. UserLAnd is spawned from work on GNURoot Debian that creates Linux containers which can be accessed from your phone via an VNC viewer. bVNC Viewer also runs on DeX (windowed or full screen) and if this all sounds vaguely familiar, it is! This is how Samsung’s Linux on DeX works.

On starting, you are provided options to create containers for Debian Linux, Ubuntu Linux and smaller Debian containers to run individual applications like games and Firefox. Double-clicking on Debian will load a base image onto your phone’s internal memory which only has the basic X Windows GUI and a terminal. You can then manually install a GUI desktop of your choice e.g. LXDE or Xfce4 + suite of applications. I preferred the look and feel of LXDE but couldn’t get any GUI to work with the Ubuntu image.

In short, it works and is perfectly usable on my Note8 either in DeX windowed or full screen mode although not particularly quick at RW operations (loading GIMP/Libre Office/installing packages). Scrolling is stuttery but mouse and keyboard input is good.

Good bits

Network connection dependent on how the Android host is connected (4G, WiFi or Ethernet).

Can access internal memory, SD Card and any USB drives connected to DeX dock.

Can access Samba network shares.

Proper desktop OS for file management and Office use.

Manually installed Synaptic Package Manager.

Real multi-tasking - Android apps still run in background e.g. music player and can be used side by side in windowed environment.

bVNC works really well in phone mode + Note8 stylus!

Not so good bits

bVNC not optimised for DeX e.g. mouse pointer offset when in windowed mode (fine in full screen), annoying window edge scrolling. At least it runs in DeX unlike RealVNC!

No sound (they are working on it).

Can't access NTFS drives (only what Android host can see/connect to).

Network panel not working (doubtful it can connect to an AD domain if Android host can’t).

Not all Debian ARM64 packages work e.g. VLC.

Not able to change default 1920 x 1200 screen resolution (missing Randr extension = Monitor Setting panel not working).

Mouse back/forward/middle buttons not recognised.

Dragging and dropping files between folders/windows is laggy - hold mouse over destination for 2 sec to be sure OS has caught up. Better with Ctrl + C/X/V.

Realistically, SnapDragon 835/Exynos 8895 Octa is probably not good enough for a professional experience (UserLAnd at least). Going through this exercise, I kinda understand what Samsung needs to do with the LoD beta; this is about developing/optimising the Linux ARM64 image and improving the Android API support.
[Samsung Galaxy S8+ Accessories] SC07 TP2:
UserLAnd has a Firefox Browser image that will create a lightweight Debian Linux container with Firefox (no further set-up) that you can use for those 'difficult' web pages. Not slick enough as your daily browser unless you own a S9+/Note9 but that'll give you a desktop class browser on DeX.

hey

just bought a pc monitor lg 21:9 ultrawide 34' 2560x1080p

is there any way to force this resulotion? it runs on 1920x1080p now i need 2560x1080p

anybody?
[Samsung Galaxy S8+ Accessories] pimikiel:
DeX displays only in 16:9. You can only stretch to 21:9 using display menu. IMO this looks awful.
[Samsung Galaxy S8+ Accessories] SmilerOnline:
This is available on the S9 running the Android Pie beta :)

So I assume that the option will be available for other devices soon too! :)
[Samsung Galaxy S8+ Accessories] SmilerOnline:
*NEWS UPDATE*

Wine now fixed in DeX mode.

Now you can run Windows apps in DeX! :)

v3.21 and above:

https://dl.winehq.org/wine-builds/android/
[Samsung Galaxy S8+ Accessories] Diaconescu_Tiberiu:
How? (Linux n00b here) I thought we can run only apps designed for arm64.

Can we run any .exe...or?

LE: Ive installed the arm.apk ... nothing happens...im looking at a black screen !?
[Samsung Galaxy S8+ Accessories] SC07 TP2:
Big caveat is that it runs only Windows RT (ARM) applications on our Samsungs and not the x86 ones we know and love(?). Situation is much like Linux on DeX (runs ARM64 stuff only).

Well, this is not strictly true but you need to run a emulator within Wine to get it to work. Nevertheless, very interesting things we can do on our phones nowadays including full speed emulations of older OSes like AmigaOS and GameBoys/Segas, etc. I think someone even wrote a Windows 98 emulator!

Here is a list of Windows programs re-compiled to work in an ARM environment for use with Wine.
[Samsung Galaxy S8+ Accessories] pimikiel:
That's exiting, I cant wait for Pie on S8.
[Samsung Galaxy S8+ Accessories] SmilerOnline:
There is a project to run Windows x86_64 apps on Android too called Wine Hangover.

I don't have the time right now, but if someone can compile it it should now work on Android 8+ as it is built on the new Wine with Android 8+ fixes!

*Note 9 Pie Beta DeX*

Hey guys, so here is a screenshot of DeX in Android Pie.

Honestly I think that the UI in DeX has not been well thought out, and it seems that DeX was an afterthought in this version of Android.

It's still usable, but it ain't gonna win any design awards in my opinion.

[IMG="DeX Pie"]https://i.imgur.com/RFi8gDf.jpg[/IMG]
[Samsung Galaxy S8+ Accessories] StardustGeass:
That looks... horrendous to me..

Well, looks are subjective things, but I really think that this layout is simply worse than before..

On the other hand, if they manage to reduce DeX crashes and multistar working correctly, I'd be sold.

The problems with apps sometimes doesn't work with keyboard and have to open/close other apps to make it work again is just plain annoying, and multistar update doesn't fix it for me at all.
[Samsung Galaxy S8+ Accessories] SmilerOnline:
Multistar doesn't work in Android P DeX either...

The DeX framework team have only gone and broken more things to be honest...
[Samsung Galaxy S8+ Accessories] StardustGeass:
That is the more reason to wait jumping to android pie for me then... since I really use DeX function a lot..

Also jeez, I really hoped Samsung made their own DeX laptop... I really think it's the time.. I'll be liking them better make one next year instead of delivering a Tab S5 or such.
[Samsung Galaxy S8+ Accessories] SmilerOnline:
Parts of the UI are not even visible or are in no way connected to the design style used throughout the rest of the device...

Honestly they need a UI engineer that pays attention to what they are doing...

*DeX Pie News update*

The DeX framework team have broken many of the components enabling developers to have more control over how their app is displayed within DeX including window size, position, etc.

Game launcher now fails to launch fullscreen because of these changes from the framework team.

Accessibility services are explicitly disabled when switching in and out of DeX, note: they already broken these services on Android 8.1.0 on the Note 9, but now it also affects S9 (Pie) users too, so only DeX experienced devs could find a way to fix this.

The level of control over the app window and sub-windows positions may be a cause for concern for many developers such as Adobe who will be bringing Photoshop to DeX soon I believe, this could cause the sub windows to display at incorrect sizes and screen coordinates, making toolbox windows useless in DeX.

It seems that the framework team have been rushing to meet deadlines and have not tested their changes at all...
[Samsung Galaxy S8+ Accessories] SC07 TP2:
This is all very concerning, particularly as these issues have been present from the Android 8.1.0 build released in November that have yet to be sorted, let alone in Android Pie. Along with the UI bugs, it seems to indicate either a development team capacity issue at Samsung (in the run-up to releasing Pie) or a downgrading in priority of DeX in the road map and QC process of both 8.1 and Pie. Hopefully it will be attended to in the release candidate.

Do the hot keys to manually position/resize the windows (and the app launch options within DeX Hub) still work in Pie?

Dex mvoip.

Hi there,

I'm looking for a solution to use Dex to call through my provider MVoiP but with the ethernet connection. VoWifi is running perfectly on Wi-Fi and VoLTE over data connection but none of them are working from my S8 in the Dex on ethernet.

I've installed a Renovate ICE 14.1 / TWRP / Xposed and Fake Wi-fi to try to trick the phone service but this is not working. Everytime I get "Switch off flight mode, to make the call" !!

Do you have any idea? VoWifi or VoLTE are simple IPSEC vpn tunnel to the provider, it should work on ethernet easily !

Thx

yA
[Samsung Galaxy S8+ Accessories] SmilerOnline:
The window position issue doesn't appear to affect non-DeX optimised apps, but if an app like Desktop Hub has a background service then it needs a parameter to avoid that service being killed when entering/exiting DeX, this also affects the UI positioning, so when the main app is closed, the start menu will launch in a location close to the main apps previous position. This also affects window sizes, so the main app may launch slightly off the edge of the screen in a fullscreen sized UI. I will try to get in touch with Samsung to see if they can fix this before the Pue release
[Samsung Galaxy S8+ Accessories] SmilerOnline:
This requires the app developer to add support for ethernet. Many devs will make the mistake of assuming that only wifi or cellular data is possible on phones and this causes your issues. A good developer will use the provided Android API's to determine if the connection has a data limit like many cellular connections or not like many wifi connections, but you still find that many will just assume that wifi is the only option that has no data limit.

But the point is that because of their assumptions, ethernet just gets completely ignored and they don't detect it within their apps...
[Samsung Galaxy S8+ Accessories] branmuffin82:
Okay, has anyone ACTUALLY been able to get WQHD/ 1440p in Dex? I went out and bought the Dex pad specifically because it says it supports WQHD. I'm using the included charger and hdmi cable and connected it to a 4k monitor and STILL it does NOT work. This is beyond frustrating since Samsung's own website claims that it DOES support WQHD. Does anyone have the final word on this? I have seen anecdotal stories of people being able to get 1440p, but most people are NOT able to get it. What is going on with this?
[Samsung Galaxy S8+ Accessories] p33l05:
After 1.5yrs of using DeX and reading various posts, researching.. I've never seen a definitive answer to this or managed to get it working in WQHD
[Samsung Galaxy S8+ Accessories] branmuffin82:
That's pretty much the same conclusion I've come to. Reading the Samsung forums, it seems like no one over there knows the answer either. If their expensive dock won't run at WQHD, there's literally no reason to even buy it. I can just use any run-of-the-mill usb c to hdmi dongle on Amazon for $20.
[Samsung Galaxy S8+ Accessories] SC07 TP2:
The DeX hardware and display software is capable of running in WQHD and other custom resolutions/screen ratios (Samsung Galaxy Tab S4 is a 16:10 screen) so the limitation is the Samsung Experience software. SmilerOnline runs a custom desktop resolution but it involves software contortions using ADB which causes problems on undocking the phone.

Why Samsung have chosen not to complete their software implementation to enable screen resolution changing is the real question. Given basic things are currently broken in Android Pie's DeX implementation, the signs aren't good at the moment.
[Samsung Galaxy S8+ Accessories] HerpToTheDerp:
Yes, I was able to get it working on my old 4k monitor just fine. Right now I'm on an S9 with the Pie beta and now I'm running UWQHD and it works like a charm. Especially with Citrix.
[Samsung Galaxy S8+ Accessories] branmuffin82:
Wow, thanks for the reply. You are the first person to actually offer evidence that it does work. Clearly this is just a software limitation then. So maybe it will officially be supported in Android Pie.
[Samsung Galaxy S8+ Accessories] SC07 TP2:
Outstanding! I'll start saving up for a new Samsung LS34J550WQUXEN 34-Inch LED Monitor this year :D
[Samsung Galaxy S8+ Accessories] HerpToTheDerp:
I was able to get QHD working before Pie was even out actually. Obviously I'm using something completely different now but it had worked then.

On another note. With the inclusion of ultrawide support Dex is almost business ready. The last thing that Dex really needs is laptop support which should be all said and done once the Mirabook is released.

*NEW DeX OPTIMISED BROWSER*

I've developed a DeX optimised browser with the simple name 'Desktop Browser'.

At the moment it is in a VERY early preview state so do expect bugs, but it is designed to try and provide an experience more inline with a typical desktop browser and less of an upscaled phone browser.

I will be busy throughout January so I will be putting this project on hold for a few weeks, but hopefully we will see some useful feedback during that time for me to work out what features/bugs need prioritising first when I get the chance to work on the new desktop browser.

[Samsung Galaxy S8+ Accessories] SC07 TP2:
I see what you are doing here (attached)...

The thing that bugs me about the Android browsers that run on DeX is the tall DeX blank window titlebar, Tab and Address (URL) panels reducing the visible web page area. Desktop Browser has moved the tabs into the window titlebar. Is there any plans to shrink them further vertically (smaller font size) as befitting a mouse-driven GUI?
[Samsung Galaxy S8+ Accessories] SmilerOnline:
I could try, but I use a touch screen monitor for DeX (though I haven't yet tested Desktop Browser on it) so I was hoping to still enable it to be fully functional in touch mode. I may add a setting to adjust their height for this reason in later releases

I tried to add all common keyboard shortcuts to the browser. But I did forget one of the biggest changes that I wanted to make...

As I have full control over this browser window I want to use that power to detect the 'Shift+Space's key combo and automatically inject a space key press into the webpage so that you can do your work without having to go back and check for missing spaces.

The reason for the browser user agent being set to Chrome for Windows is to increase desktop mode optimisations in websites without the common mistakes that we see in Samsung internet showing a mobile UI on pages such as Facebook.

The tabs are currently fixed to three as I want to provide a way to allow your YouTube videos to continue when you switch tabs, as I find it annoying in Android browsers when I have to pause the video when switching tabs, though the current solution doesn't (yet) support dynamic adding and removing tabs. The browser does support multi window to extend your available tabs though, although this is still not quite as polished as I want it to be.

The bookmarks bar is a premium feature just to give me incentive to continue developing this browser long term. As I don't use your data or do any deals with search engines this is the only income from the app.

The mobile experience is barely optimised.

For now it kind of works but I wouldn't suggest it's better than any other mobile browser.

The design of the browser follows similar design standards to multiple browsers built for other desktop operating systems.

The overriding of the title bar may cause the app to break on other desktop devices as no testing has been done on those, hence that it says it's a DeX exclusive browser.
[Samsung Galaxy S8+ Accessories] SC07 TP2:
Interesting... As an aside, can you tell us what make and model of touch screen you are using that works with our Samsung DeX enabled phones, please? How does the display's touch interface connect - via USB or Bluetooth? Any lag from touch input to app response?

I've always fancied a large format touch screen that I can mirror the phone's screen for touchscreen games (ala Surface table, Surface Studio folded flat or Wacom Cintiq) but didn't want to take a risk of buying one and it didn't work.
[Samsung Galaxy S8+ Accessories] SmilerOnline:
Kenowa 15.6 inch portable touch screen (USB-C connection required for touch support, though it does also support video only mode over HDMI).

I often find that when its connected via USB-C, it continues to start and stop charging the phone causing the phone screen to wake.

It also requires a separate USB-C power adapter, though any USB-A to USB-C cable seems to provide enough power so I stuck a slim power bank on the back to provide power to the display (which also passes power over to the phone as I mentioned).

*Desktop Browser update*

If you have the Shift+Space filter enabled in Desktop Hub, the latest update will send a call to apps such as Desktop Browser to enable it to insert a space when you press shift+space.

The reason this is not built into the browser alone is because it would require another heavy backend service just to handle one basic function.

Also added find in page support (ctrl+f to open or click the overflow menu icon to see the 'find in page' button).
[Samsung Galaxy S8+ Accessories] pommejaune:
Hello SmilerOnline, thx for the feedback. I know that this issue is related to development. I've tried to exchange with the dev guys developping the Orange phone app replacement but they are not opened at all. :silly:

What do you think, is it only related to the dialer app? I'm currently checking theses ones, addappt, Exdialer, Metro, Simpler or Truecaller. I always get "Turn off flight mode to make this call"

You are far closer than me to this world, do you an idea how to tackle this issue??
[Samsung Galaxy S8+ Accessories] SmilerOnline:
To fix these apps I would neded access to their code.

Google provided developers with tools to handle network connection properly, and any good developer will use them, but you still get some developers who think that they know better and do this kind of stuff, assuming that mobile phones will never have an ethernet connection.

I would like to see the DeX framework team add an option to simulate a wifi connection when ethernet is connected, so all apps think that they are connected to WiFi, but technically you are connected to ethernet.
[Samsung Galaxy S8+ Accessories] editcue:
That's a very excited improvement . Dose it support 3840x2160 resolution?
[Samsung Galaxy S8+ Accessories] HerpToTheDerp:
There is no native support for 4k resolution. Only the ones in my screenshot are supported as of the latest update.
[Samsung Galaxy S8+ Accessories] orelsi:
Hey guys,

Have there been any developments about the TV/monitor screen ratio issues? There are some TVs that do not have the required options to change the aspect ratio (despite being FULL HD, for example), so the Dex bottom bar and side icons fall outside of the borders without a way to fix it from the TV. The Samsung help pages have only this text "If the screen ratio is incorrect, adjust the screen ratio from the menu of the connected TV or monitor." The fault is not with the phone or Dex, it is strictly with the TV's lacking the options, but it is extremely frustrating. I was hoping for a way to fix it via software from the phone, but nothing came out.

Has there been anything new on this front?
[Samsung Galaxy S8+ Accessories] SmilerOnline:
No, I don't think that they want to use a software fix on the phone as DeX is designed to be connected to different displays continuously and setting the over scan values in DeX would cause other displays to show black outlines.

So generally it works best just to fix the issue on the display itself.

POE for the DEX

Hello,

I'm trying to use my POE switch to power up the DEX.

I've been using a POE splitter with a 5.5 DC cable to USB-C but this is not working.

The plitter is a Trendnet 104GS with a 9V 2A splitter.

Any idea? Wrong cable? Why is DEX not POE compatible?

Thx
[Samsung Galaxy S8+ Accessories] SC07 TP2:
The DeX docking station (I don't know about the DeX Pad or USB-C to HDMI docks) is notoriously sensitive to the power supply that is plugged into it. There are a lot of (fake?) Samsung Fast Adaptive Charging units out there that DeX just won't work with for example. According to the Trendnet 104GS specification, it can put out the minumum 9V 1.57A but I guess something inside the DeX Dock isn't happy with the supplied electricity.
[Samsung Galaxy S8+ Accessories] SmilerOnline:
Always be sure to look for USB-PD (Power Delivery) to ensure that it will have the power capacity to charge anything.
[Samsung Galaxy S8+ Accessories] undertaker2k14:
Seems Dex on my Note 9 is not working because of security policy about USB host storage any ideas? Used to work before...using Dex Pad my Tab S4 works without issues. Anyone else getting 'Security Policy Prevents use of USB Host storage' and/or Dex issues with the Note 9 while on samsung device insights? I am on latest Nov 1 patch here in the US.
[Samsung Galaxy S8+ Accessories] pommejaune:
Hello, the original Samsung power supply adaptor is providing 9 V (1,67 A) and 5 V (2 A)

The output of the trendnet is providing 5 V (2 A), 7.5 V (2 A), 9 V (1.7 A), 12 V (1.2 A).

Now the POE Trendnet and the carble are working with the S8 directly. This is charging. I suppose that this is using 5 V in this case.

When the DEX is connected the Trendnet LED is switching off. How is the DC 9V wired on the USB-C ? Maybe this is the question or I would need more power.

Desktop Browser coming on leaps and bounds in usability over past three weeks which is really encouraging. :good: It is very quick as well. Not bold enough to adopt as my daily driver yet.

How wary must you be about development suggestions that appear to copy/are implemented features in other browsers e.g. clear, paste and go for URLs copied into the clipboard from other apps?
