I'm running a clean install of 12.04.02 (i.e., direct from the 12.04.02 install disk, not upgraded from 12.04.01). All packages are up to date. My hardware includes a Gigabyte GA-Z77-HD3 with a Sandy Bridge Celeron, and I'm using the on-board Intel HD graphics.
I keep getting GPU lockups. They're not the "false" ones often reported. The error message (copied by hand because Apport won't let me copy from the UI) is:
Under "package", it says "xserver-xorg-video-intel (not installed)". Further down, it tells me to upgrade or install that package. But when I try to do so, I get this error:Code:
[sandybridge-gt1] GPU lockup IPEHR: 0x23002000 IPEHR: 0x0b140001
I don't understand what that means, or why I'm getting a crash report from a package that isn't even installed. What should I do next?Code:
kevin@aphrodite:~$ sudo apt-get install xserver-xorg-video-intel
