Comment 18 for bug 34590

I do not recommend the use of dougfractal's above script.

It rendered my system unusable, with Xorg broken, the ati driver package broken and no means of restoring it, with the backups all pointing to the destroyed ati driver.

I had to download xserver-xorg-video-all and xserver-xorg-video-ati onto a memory stick from my other computer, purge them on the laptop in terminal then use sudo dpkg -i to reinstate them.

Without another computer or a cable connection, and decent knowledge of terminal commands, you will not be able to recover your system, and may be forced to reinstall.

Just hold out for an appearance in Gutsy, or use Mepis.
