Booting to Black Screen with Fuzzy Lines

**jdorenbush** · July 19th, 2009

Running Ubuntu 9.04 64. Tried to install ATi driver today. After what seemed to be a successful install I rebooted only to end up stuck at a black screen with some fuzzy colored lines at the top portion of my screen.

It goes through a normal boot process, I see the Ubuntu splash loading screen, and right about the time I should be seeing my login window -- instead I get the black screen with fuzzy lines.

Update: More descriptive...
- Small red lines at the top 1/4 inch of my screen.
- About an inch thick green and purple lines 3/4 the way to the top of my screen.
- The screen blinks three or four times than just sits there, with the weird colored lines.

Any idea how to fix or just uninstall the driver? I've uninstalled/reinstalled xserver-xorg-video-ati and uninstalled xorg-driver-fglrx -- neither seemed to the fix the problem.

Boot into "recovery mode", select "drop to a shell", uninstall the driver in question

Thanks for the quick response. I'm at the shell. Any chance you can help with command to uninstall driver? I ran this:

Code:

sudo apt-get remove xorg-driver-fglrx

That apparently didn't work though. I am still having the problem.

This is the driver.

I believe the correct command would be "sudo dpkg-reconfigure xserver-xorg" (without the quotes)

I did uninstall it. At least I think I did. sudo apt-get remove xorg-driver-fglrx

I ran through that process too. No luck.

Thanks. I got it fixed. From that link I found https://wiki.ubuntu.com/X/Troublesho...thRadeonDriver

Just did all of the following:

Code:

  sudo /usr/share/ati/fglrx-uninstall.sh  # (if it exists)
  sudo apt-get remove --purge fglrx*
  sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon 
  sudo apt-get install xserver-xorg-video-ati
  sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
  dpkg-reconfigure xserver-xorg
