Open Source ATI Driver

I have messed up the graphics on my system. Right now it is so slow that even simple typing is falling behind.

Try to switch back to the open source ATI driver.

https://help.ubuntu.com/community/RadeonDriver

This driver only does 2D support for Xpress type cards.

My card type.

01:05.0 VGA compatible controller [0300]: ATI Technologies Inc RS485 [Radeon Xpress 1100 IGP] [1002:5975]


Removing the proprietary driver.

$ sudo apt-get remove --purge xorg-driver-fglrx

Verify that proprietary drive is removed

stan@stan-laptop:~$ glxinfo | grep vendor
server glx vendor string: SGI
client glx vendor string: SGI
OpenGL vendor string: Mesa project: www.mesa3d.org
stan@stan-laptop:~$

Make sure that the open source drive is installed

sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri

I also need the install CD

Media change: please insert the disc labeled
'Ubuntu 7.10 _Gutsy Gibbon_ - Release amd64 (20071016.1)'
in the drive '/cdrom/' and press enter
