Xda-developers forum member CalcProgrammer1 is porting Ubuntu 11.10 Linux to run on the Archos 43 tablet with a 4.3 inch display. It also works on the original Archos 101 tablet with a 10 inch screen.
Most basic features are working, including the touchscreen, WiFi and Bluetooth. Screen rotation is also supported.
But CalcProgrammer1 is still working on hardware graphics acceleration and some other features.
While Android is designed specifically for mobile devices including phones and tablets, Ubuntu is a full-blown desktop operating system capable of running desktop apps such as LibreOffice, Firefox, and the VLC Media Player — all of which work on the Archos tablets.
The biggest problem with running Ubuntu on the Archos 43 is that the operating system isn’t really optimized for tiny tablet displays, so you’ll probably want to connect a keyboard and mouse rather than tapping tiny icons and menus with your fingers.
Both the 4.3 inch and 10 inch tablets feature 1 GHz TI OMAP 3 ARM Cortex-A8 single core processors with PowerVR SGX 530 graphics. They originally shipped with Android 2.2 Froyo software, and while Archos offered a few software updates with bug fixes and minor improvements, the company never released Android 2.3 or Android 4.0 for those tablets.
There are also several other members of the Archos Gen8 family including tablets with 2.8 inch, 3.2 inch, and 7 inch displays, but this particular build of Ubuntu hasn’t been configured to support those devices yet.
