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.
