Black screen on boot after installing ati drivers

Question

System: Xubuntu 12.10 x86

I installed the Ati drivers using the Software Center, everything apparently whent fine (no error messages).

After rebooting the system i get a black screen. The system responds to input (if i press the power down button it closes gracefully) but is completely unusable. From the boot menu i can decide to load the root terminal, but i have no idea of what to do in order to remove the drivers.

Following some guides i looked for:

• the Xorg.conf file in /etc/X11
• /usr/share/fglrx/fglrx-uninstall.sh
• /usr/share/ati/fglrx-uninstall.sh

But they were all missing. What steps can i take?

Solution 1

This is a known problem with ATI drivers on Ubuntu 12.10 (see https://bugs.launchpad.net/fglrx/+bug/1068661/+index?comments=all). I got my hybrid graphics system working by following the instructions below:

How do I get AMD/Intel Hybrid Graphics drivers to work?

If you don't want to compile drivers, installing the xserver-xorg-video-intel and one of the fglrx packages from this PPA should work:

Solution 2

I found the solution: i had to enable networking and then use:

sudo apt-get remove fglrx*

This seemed to fix things up.
