Use 'sudo' instead, with 'gtab' as the password. To become root, use 'sudo su', then issue the 'passwd' command to set the password for the root user. The stock Ubuntu install does not set a root password by default, and I left it this way.
[G Tablet General] umar.ranjha:
I guess i figured the problem. Permission was set to 777. I have Untar the Karmic root file system and leave the Permissions as is and everything worked fine after that.

[G Tablet General] micrors4:
I am a bit new to linux and I don't understand how to mount the sdcard in terminal as well as transferring the files to the sdcard, so could someone create more detailed instructions on how to set up ubuntu on the tablet for those of us who are having trouble?

EDIT: Never mind it wouldn't mount it because the name of the sdcard had a space in it, I feel really dumb
[G Tablet General] joshua.lyon:
This would be awesome as a dual-boot setup with XBMC for when you want to use your tablet as a media player (either directly on screen or HDMI to your external display).

The Boxee Box was originally designed with the Tegra2 chip, but they swapped it out for the Intel CE4100 last minute due to problems with support for high-profile HD playback (reference).

On the other hand, it sounds like there has already been some work on XBMC Tegra2 Development over at the NVidia Tegra Developer Zone.

It's unfortunate to see it re-iterated so many places that h264 High Profile is such an issue for the Tegra2 SoC... and I'm surprised I haven't seen much feedback from NVidia on it (especially after the boxee incident).
[G Tablet General] crazy talk:
hope this hasn't been discussed, but will this work with standard Ubuntu programs? and will it work with external hardware through the USB port if the proper Linux drivers are in place? and do those drivers have to be Tegra2 specific?
[G Tablet General] NMCBR600:
In my tests, as long as the drivers are there they work. I hope they get the touch screen working.:)

I have Zpad and am using VegenTab b5.1 rom at the moment, I have my 16g external sdcard recognized as "sdcard2" and the internal one is "sdcard", I format the total 16g external one as ext3 and even give its label as sdcard (so when using it with usb card reader and in ubuntu it is shows as /media/sdcard), I untar the root file system and flashed the boot image attached.

It stuck at reboot. has it to do with /dev/block/mmcblk2p1 thing, could I hard code it to something else and how? could you pls give a bit hint... many thanks in advance.
[G Tablet General] TheTruth:
ive tried to get ubuntu 10.10 working with acceleration... but we will never have x11/xorg/xserver (latest abi) until nvidia or xorg support acceleration via a new driver... older versions of ubuntu do work with acceleration but no multitouch support... ive read that it is possible to use 10.10 but over an older kernel (and thus opengl and x11) but that defeats the purpose as multitouch would still be lacking...
[G Tablet General] NMCBR600:
Have you queried Nvida for any information? Also, could you provide any information on how your ubuntu kernel was built and how to update the existing kernel? I'd like to add additional devices to you're load.
[G Tablet General] famou:
I tried all your lab procedure, still no luck to do the same on Zpad, just to confirm, did you use the boot.img from the first post for your lab notes? this is not clear from the text...

could you please clarify a bit on mkbootimg, I guess each time you also do mkbootfs, and also could you pls elaborate a bit more on the last trick of "remove init from ramdisk", do you simply delete the init under ramdisk directory, what have you hardcoded as the name refers?

one more question pls by using console=tty0 I still cannot see the booting sequence message, it is still the picture then stuck. I also tried dev/mmcblk3p1 or dev/block/mmcblk2p1 etc

Thanks for guidance
[G Tablet General] vgrade:
Hi There,

Thanks for the feedback. See inline
[G Tablet General] famou:
Wired but when I download the VeganTab B5.1 boot image and after did the split_bootimg, I did not find the /sbin/init as used in your successful test, there is only a /sbin/adbd available, maybe I'm totally stupid, does this /sbin/init refer to the ramdisk's /sbin/init or the Ubuntu fs's /sbin/init?

So you have rebuilt the kernel with CONFIG_VT=1, did you use pershoot's kernel source?

Thanks in advance.
[G Tablet General] vgrade:
Remember my instructions are for a stock vega.

You should be able to extract the boot.img from your device.

The init is the one on the ramdisk not on the ubuntu fs.

I have not rebuilt the kernel as I don;t have the source for the vega. But its avaiable for the gtab i think.

Awesome, lets get some Natty Narwhal on this thing.
[G Tablet General] TheTruth:
really nothing useful in response to my post... as you say, unity 2d needs no acceleration to work well... but i wasnt talking about unity... i was talking about xorg and how all would like hardware acceleration and multitouch support - which will not happen until a driver from nvidia is working with the latest xorg used in 10.10 (1.8.something).

sooooo good idea for unity to speed up the interface while we have no hw acceleration ... but realize this has nothing to do with improving other capabilities : video playback, multitouch, games, etc... all which need hardware acceleration.

[G Tablet General] famou:
Learn it in a hard way :( just record my lesson for Zpad users, this is the way to make it happen:

1. Do a "nvflash FULL restore, using bekit's original image (Instructions)" this is the post title by roebeet, to really turn the zpad into stock g tablet, I notice the partition of the two stock roms are in fact different (different bct table)

2. Do as post one in this thread, it works, but at first start it wait unexpected long time before it goes on, after the booting message:"/tmp:waiting for (null)"...around 10 minutes in my case...have to be VERY patient. Now it's working. Thank everyone here!

hey anyone have luck getting the touchscreen to work? i tried installing the eGalaxTouch driver but unfortunately after running sh setup.sh as sudo and rebooting, the command "eGalaxTouch" returns an error:

/usr/bin/eGalaxTouch: 1: Syntax error: "(" unexpected

pretty noob w/ linux so not sure how to fix that/ what the deal is.

also, as i'm writing this from the tablet and searching is slow/etc, can someone PLEASE LINK ME A BACKUP boot.img (not sure if it matters but I was using the latest CM ROM) - I'd like to be able to switch back and forth... haven't tried it yet but i'm hoping clockwork can still be loaded the same way... and i can just apply a .zip to fix the boot.img?

gTabUbuntu

I'll be installing this later. It would be nice if the source for this project was available so I could tinker with it some. I've installed about every rom on my gTablet, restored it from two bricks. If I could get a stable Ubuntu with touch functionality on this tab, I'd be overjoyed. I need to have full OpenOffice functionality, plus media playing capabilities. I don't care if any of the other buttons work. If I can get a touch screen working, that's all I really need. The buttons on the side would just be additional inputs.
[G Tablet General] imadsen:
I've got it installed after a few hiccups.

Goals:

Need sound to work properly.

Need graphics acceleration (work nicely as it is, but not fast enough).

Need touchscreen capabilities.

Need Volume, Power, and Soft Keys functioning.

Also, the battery says it's discharging, but I know I have full power. Any ideas what might be causing that problem? Unfortunately, it seems development has slowed to practically a halt here, but I'm willing to pick it up again. I'm sure I can solve these problems with a little help. Just need a few pointers in the right direction.

I'm trying to figure out how to get a working boot image. I've compiled pershoots kernel, use mkbootimg to create a boot image that should boot from mmcblk2p1, but all I get is a black screen after the initial boot screen,. The boot image for karmac will only boot so far and stop as it cannot load the /dev to the root. I'm too use to building kernels for x86.
[G Tablet General] Triskite:
In regards to getting the touchscreen to work, it seems that the manufacturer is Sintek / Hanvon.

After spending a while trying to get touch working, I seem to have broken the tablet somehow. Tried factory reset with CWM and restoring an earlier image (actually, I tried several) to no avail. Re-applying the karmic-boot.zip boot.img and trying to boot Ubuntu doesn't work either:

"

Gave up waiting for root device.

ALERT! /dev/mmcblk2p1 does not exist. Dropping to a shell!

Any ideas?

I'm trying to get the new version of ubuntu that they have running on the vega to boot. The boot image is what is giving me problems.
[G Tablet General] imadsen:
The installation of Ubuntu for me was a long process. If you need to get back into Android, you'll need to reinstall an android bootloader, and a lot of roms don't seem to update that. I've been working 13 hr days this week, so my progress is really slow on this unfortunately.

Using System > Preference > Keyboard Shortcuts, I've discovered a few things. The only reason the power button doesn't work is because it's improperly recognized as F4 by default and the Suspend action has been disabled by default. The volume buttons are recognized and do work, but without audio enabled, they're useless. Soft keys aren't recognized at all, so I'll have to dig some more to get them functioning.
[G Tablet General] imadsen:
I took a look at that. Seems to me the driver is faulty or at least it's output isn't recognized yet.
[G Tablet General] NMCBR600:
Are you using karmac or the test releases of 11.04? I'm trying to get 11.04 running.
[G Tablet General] imadsen:
Looks like it's not recognizing your external miniSD card to boot into Ubuntu. If you want to factory reset it, you'll need to get the original vanilla distro I think or reinstall your bootloader. I haven't bothered trying any of that yet though, since I'm tinkering with Ubuntu right now. Seeing as I'm deploying to Iraq in a couple months though, unless I get Ubuntu running up-to-speed with touch and everything, I may switch back.
[G Tablet General] imadsen:
I've already got enough issues to work through before testing an alpha release. If I had the time to code everything from scratch, I would. I haven't ever messed much with kernel coding, so this is a bit of a leap for me, but a good learning process.
[G Tablet General] imadsen:
A company called Enac has a Linux/Android driver for the touchscreen, but it's for Kernel versions 2.6.38 and up. It seems more and more our best bet is a newer Kernel. Otherwise, with no keyboard or mouse, this device will be useless, and I can't bring a keyboard and mouse everywhere with me on the go. If I can get the native android driver to work in Ubuntu, the problem will be solved, but I have no clue where to start with that.

Edit: Thanks everyone for the help and support so far. I'm gonna throw as much extra time as I can into this project. But for tonight, I'm off to bed. Soon enough, I'll actually be able to put links up, and that'll really help things get moving faster. I plan on starting up subjects in related forums to see if I can get some more people involved that are already working on related projects.
[G Tablet General] Triskite:
Did you try the Enac driver even though it's for .38 +?

Somehow I completely lost the recovery (CWM) and such but I just reinstalled it, so not a big deal.

Pretty confused - none of my CWM backups restore properly. I've tried repartitioning, full factory wipe from CWM, wiping cache after restore, restoring system/data/cache after full format + install CM . zip, etc. No dice. wtf, mate.

Stuck on "Android" during boot, won't go past.

Was using CM7 Harmony

Well, I ran into a slight problem. Totally borked my device trying to switch back over to Android. If anyone can help me get back into Ubuntu or Android instead of sitting on my "Recovery key detected" screen, I'd be overjoyed.

Problem booting: "mounting /dev on /root/dev failed: Invalid Argument"

Problem booting: "mounting /dev on /root/dev failed: Invalid Argument"

I'm not sure what's up. I formatted the card as ext3. If I boot the viewsonic without the SD card in, I can get to its busybox ash shell. If I plug the sd card in then, I can mount it on the viewsonic:

cd root
mkdir foo
mnt /dev/mmcblk2pi foo
EXT3-fs: mounted filesystem with writeback data mode

So, I've got the right FS on there, and all the data seems to be intact.

Booting with the SD card in there, I get:

[8.4979] EXT3-fs: mounted filesystem with writeback data mode
begin: running /scripts/init-bottom
mount:mounting /dev on /root/dev failed: Invalid argument
...
[8.5918] Kernel panic - not syncing: Attempted to kill init!

I'm confused; "Invalid Argument" usually means "guy is using a filesystem that he didn't compile into his kernel", but I've verified that I can mount it in busybox, and the /scripts/local-premount step mounted the filesystem just fine.

Any advice?

[G Tablet General] NMCBR600:
The invalid message is common as it's trying to mount into the ram disk image which is read only. Are you using the karmac image or the one for natty? You did expand the file using sudo?

You can keep Android as your root OS and run Ubuntu sandboxed on top of it.

That being said, if I could get touchscreen support, sound, and wifi, I would install Ubuntu as the root OS on my gTab in a heartbeat and only flash back to Android if I absolutely needed to for some reason.

Ubuntu on VeganTab?

I've got a G-tab running VeganTab 2.2. Everything runs gorgeously; HD video, multitasking, etc. My Ipad friends looks at me playing non-mobile YouTube playlists in the background while I play angry birds and they totally freak out. THANK YOU XDA for helping with Vegan tab and making this, the hottest low-cost compact solid state computer on the market, more usable.

In any case, I have been unable to find an acceptable word processor (I've tried everything in Android), which is the main reason why I want to install Ubuntu. So I have two questions:

1. I get that there's no duel boot yet :((( and I've looked at

hxxp://hdfpga.blogspot.com/2011/02/ubuntu-on-tegra-2-tablet-android.html

and I think I could follow the instructions, but it involves installing Ubuntu over Zpad Clean 3.0; would the same instructions work for running Ubuntu over VeganTab 2.2?

2. An odd question, I know, and maybe not the right thread (it's my first post, so please, no preaching about appropriate posts): In Ubuntu, running OpenOffice, MS Word, or Celtx, does the right-click keyboard key work? This is NOT the right click mouse key; it's traditionally positioned near the Ctrl and Alt keys in the lower right, has a pic of an arrow cursor over a menu. I depend on this key in word processing. Not having it would be a deal-breaker. I've never used Ubuntu; my question is, on regular computer, when you run a word processor from it, is this key functional?

I'm about to take off for a 14 month backpacking stint in Latin America; I want to bring one light computer with me. I have two months to get my G Tab solidly running word processing and screenwriting software, or else I'm gonna have to just sell it and buy a Win 7 netbook. My G tab kicks every netbooks @#$ in so many ways; it would be a shame to give up on it. I think Ubuntu is my best shot...
