Bug Description

I reported in #44075 that suspend/hibernate are
broken on a ThinkPad X30, but the bug got
reassigned and hasn't been addressed.
SAVE_VBE_STATE=false solves the problem, so
could you make acpi-support use that?

As it's being blamed on the X driver, perhaps it
should also be done for other systems. lspci
identifies the graphics as

Intel Corporation 82830 CGC [Chipset Graphics Controller]

Can anyone remember how exactly this was "fixed"? Because I have the same kind of problem on 8.04 and have for the last two years.

After every resume from sleep, the text console would be more and more corrupted, and eventually (perhaps after 5 resumes) I would have dirty black artifacts on the mouse cursor and scrolling problems under X, and the system would be unstable. If I hibernate at this stage instead of suspending, it normally restores the machine to functioning state, but wasted 5 minutes.

I found by trial and error that setting SAVE_VBE_STATE=false appears to have fixed the problem for me, and also made resuming much faster as an added bonus. I gather from bug #60882 that this causes problems on Fujitsu Lifebooks, so this probably isn't a global fix, but it seems at least to apply to Thinkpad X31 and X40.
