Comment 40 for bug 750437

Okay, I've not tested this long enough but I decided to give the drivers absolute latest drivers a shot, ie amd-driver-installer-12-6-x86.x86_64.run ie:

[ 12.508] (II) fglrx(0): Kernel Module Version Information:
[ 12.508] (II) fglrx(0): Name: fglrx
[ 12.508] (II) fglrx(0): Version: 8.98.2
[ 12.508] (II) fglrx(0): Date: Jun 11 2012
[ 12.508] (II) fglrx(0): Desc: AMD FireGL DRM kernel module
[ 12.508] (II) fglrx(0): Kernel Module version matches driver.
[ 12.508] (II) fglrx(0): Kernel Module Build Time Information:
[ 12.508] (II) fglrx(0): Build-Kernel UTS_RELEASE: 3.2.0-26-generic
[ 12.508] (II) fglrx(0): Build-Kernel MODVERSIONS: no
[ 12.508] (II) fglrx(0): Build-Kernel __SMP__: yes
[ 12.508] (II) fglrx(0): Build-Kernel PAGE_SIZE: 0x1000

$ ls /var/lib/dkms/fglrx/
8.980 kernel-3.2.0-26-generic-x86_64

You'll want to follow that: https://help.ubuntu.com/community/BinaryDriverHowto/ATI#Manually_installing_Catalyst_12.6 to manually install them. You needn't uninstall the old ones first, just run buildpkg command and it will give you 3 .deb files to install.

I noticed after doing this I see:

$ fglrxinfo
display: :0 screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: ASUS EAH5450 Series
OpenGL version string: 4.2.11733 Compatibility Profile Context

instead of:

$ fglrxinfo
display: :0 screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: ATI Mobility Radeon HD 5000 Series
OpenGL version string: 4.2.11627 Compatibility Profile Contex

Also I think the kernel panics have stopped, others might want to test this to confirm? perhaps then we could have our packages version bumped or something in backports.
