Installing Ubuntu on Viewsonic G-Tablet

Ubuntu runs fairly nice on the GTab. Find a video below to see it boot. Performance is not as smooth as Android, but I've already narrowed down some kernel tweaks to speed it up.

What works:
USB Devices
Wifi
Video (not accelerated)
Internal/external storage

What doesn't work (yet):
Touchscreen
Softkeys
Volume/Power buttons
Accelerometer
Camera
Audio (pulseaudio hangs, haven't investigated)

To get it working, I used a custom kernel with added support for various drivers, but otherwise pretty much the stock VS kernel. It gets the rootfs from the micro SD card, so it only requires a boot.img flash (so it doesn't destroy any user data or the Android system partition).

Code:
cd /media/sdcard
tar -xzvf /home/user/Desktop/karmic-rootfs.tar.gz

Install the boot-karmic update zip via ClockworkMod Recovery. ***MAKE SURE YOU HAVE A BACKUP boot update.zip (or grab one from Clemsyn's Kernel Corner)***

Insert the sd card and boot. You will see some yellowish/gold colored text quickly scrolling across the screen - this is normal. This should boot straight to a GDM login screen.

Wireless will work with wicd (not NetworkManager), and you should use a USB hub with a USB keyboard & mouse.
