View Full Version : [ubuntu] Uninstalling screen driver from command line

July 21st, 2009, 06:32 PM

Long story cut short ...

- I installed kernel 2.6.30 on my desktop machine, as described in this thread here:


- This broke the machine - the login screen was messed up, and unusable.

- I wiped the install and re-installed from the CD.

- I re-installed the 2.6.30 kernel, and it worked fine. I was about 95% of the way through installing everything I wanted on the machine, when ...

- I installed the same screen driver as I had originally, re-booted, and the login screen was messed up again.

So now I have a machine which will boot to a command line, but won't boot fully into Ubuntu. Seemingly because there is a conflict between my screen driver and the 2.6.30 kernel.

The graphics card I have is on-board the motherboard, and it's an ATI Radeon HD 330 card, and I *think* the screen driver that was installed was a fglrx one. (It was selected automatically and listed as 'no enabled'. I clicked on 'enable this' and re-started, and the problems as described above re-started ... )

So, my question. How do I change back to the original screen driver from the command line? OR how do I change back to the original kernel from the command line? Either will do ...

Thanks, in advance, for any help anyone can offer. For what it's worth, when I ruined the first installation I posted this thread here:


Oh, the install is 9.04 Jaunty. And I'm a bit of a beginner (rarely venture out of "Absolute beginner talk", so please talk slowly ... thanks!)

boot to recovery mode; sign in as root; and then sudo apt-get remove the driver that caused the problem

Fab! Thanks - that sounds simple.

How do I know what driver it is? Is there any way I can get the system to display the screen driver it is using?

(That question may reveal just how much of a beginner I am. Apologies ... and thanks.)

Got it. It was this:

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

Thanks for your help.
