Ubuntu Netbook 10.10 installs but to a desktop version, citing a lack of unity driver

Asked by richard shaw on 2011-02-15

I installed Ubuntu 10.10 netbook onto my girlfriends advent kc500. It installed fine but said there was no unity driver. The desktop version is what it loads to, and it works fine apart from crashing a bit too much. The resolution is stuck at a max of 800 x 600 which makes things a bit tricky to use. I'm guessing the graphics drivers are not working correctly in some way, but I'm at a loss as how to update fix the issue. I just tried live booting from USB to the latest version to see if that helped but the same process happened. I've seen a similar question but that said to log off and to choose the unity option as opposed to the desktop version, but that option is not available as far as I can see. It doesn't show any laptop specific options in the settings menus ( monitor option) and I can't find any updates on the Internet to the graphics card (SIS Mirage3).

add this code:

Save the new file and close gedit, reboot to test. If you get no desktop, reboot, hold shift and select recovery mode, then select root and run:

mv /etc/X11/xorg.conf /etc/X11/xorg.conf_old; reboot

Then you will be back where you are
