Comment 201 for bug 541511

It's escape, not shift. And you only need to do this if your GRUB
automatically goes right into the OS.

If you successfully are at the GRUB menu, select the second line,
"recovery mode" rather than the normal boot and select "failsafe
graphics mode" from the menu which eventually appears.

For now, we mark all automatically reported GPU lockups on i855 as duplicates of this unless there is a reason not to. There are some tests you may do to help upstream with this issue, and I will come back with instructions here. For those of you who know how to patch and compile a kernel you may look at comment #30 (and #6 for what kind of feedback they want) in the upstream bug report. Actually, if someone could volunteer to build an ubuntu-packaged kernel with this patch for others to test, that would be nice.
