Attempt to upgrade to Raring Kernel "broke" graphics system

Asked by Jaime Cruz

Running 12.04.2 Precise with the Quantal kernel. Since 12.04.3 was announced with the Raring Kernel, I thought I'd update (I'll NEVER learn).

I used the following command:
sudo apt-get install --install-recommends xserver-xorg-lts-raring

After the reboot I immediately noticed I lost the wireless driver and was unable to get it reinstalled. Since I had the wired connectivity, I didn't really mind. However, as soon as I tried showing a movie trailer from http://trailers.apple.com/trailers/ my system locked up SOLID. No keyboard, no mouse, no alternative but to hit the "BRB" (Big Red Button).

I'd seen this before and it was related to the AMD Radeon Driver I was using, so I went to the proprietary drivers selection and selected the standard (not "experimental") driver and rebooted. That didn't help, I got the same problem.

So, deciding to cut my losses, I rebooted from my prior Quantal kernel. I got my wireless connectivity back, but I was still getting the screen lockup from the Apple site. When I checked the available drivers, I now don't even see the "standard" driver anymore. Just three "experimental" builds and one called "post release updates." Seeing no other option, I installed and activated that one (according to Catalyst, it is "Driver Packaging Version 9.01-121018a-148764E-ATI") however I'm still seeing the lock-up problem.

Worse, when the screen blanks (due to inactivity) I cannot get it back. Moving the mouse or touching the keyboard does NOTHING. ALL of this worked before I STUPIDLY tried to update the kernel. I've since removed the 3.8 kernel and all of its supporting files but that hasn't helped. How can I get my system back to the way it was???

try reinstalling the proprietary video driver package. It will make dkms rerun and may help

Okay, I ran the sudo dpkg command and after the reboot reran the dpkg -l | grep fglrx command and came up with:

rc fglrx 2:8.960-0ubuntu1.1 Video driver for the AMD graphics accelerators
ii fglrx-amdcccle-updates 2:12.104-0ubuntu0.0.1 Catalyst Control Center for the AMD graphics accelerators
ii fglrx-updates 2:12.104-0ubuntu0.0.1 Video driver for the AMD graphics accelerators

However, when I went to the Apple site I linked in my OP, as soon as the video (ANY video) loaded, the system locked up solid again... :-(

sudo apt-get --reinstall install fglrx

Reboot to test.

I tried that, and it "sorta" worked... BUT I can now only boot into the Unity 2D interface. Ideas?

EUREKA! While awaiting a response, I decided to try installing driver updates from the "Additional Drivers" tool. I first tried the post release updates and that locked up when I tried the Apple site. I then decided to try the "experimental" drivers to see how those worked out. Second time was the charm! I can view the Apple videos again and everything else seems to work as well.

I think I've learned my lesson regarding kernel updates. "If it works, DON'T FIX IT!!"

Thanks again for your assistance.
