tail -n 500 /var/log/messages immediately after restarting after crash
Immediately after the crash, I hit Ctrl+Alt+Backspace to kill X and go back to
the Gdm screen, and then login. After log in, I notice that gnome-shell starts
using Gallium on llvmpipe, where it had been using "Mobile Intel GM45 Graphics
Chipset" prior to crash. If I restart the computer, it starts to use the Intel
GM45 graphics again.
I have attached the last 500 lines of log from /var/log/messages immediately
after the crash. What happens at "Jul 6 11:21:08" as documented in the log
might be interesting. It starts to report problems like:
