I just wanted to confirm that I have this bug with the missing
redraw/refresh of the screen also.
I got a IBM x40, output from `lspci`:
00:02.0 VGA compatible controller: Intel Corporation 82852/855GM
Integrated Graphics Device (rev 02)
I noticed too that the possibility for the bug to occur is much bigger
the longer you wait until you resume. I have tried to suspend and resume
many times in a row... nothing happens. But often when I suspend at work
when I resume 15min or 2 hours later this happens.
I good example is when I resume my laptop the only thing I can see is
the text field for my password, the rest is just black. When I enter it
I can see my desktop, but the background of the icons from gnome-power-
manager and NetworkManager in my Notification Area is now black instead
of the same color as the panel.
If I try scroll on a web page in firefox I can see some flickering in
the top and bottom of the visible part of the homepage within the
browser, but mostly the page appears to not scroll (only the flickering
and the scrollbar actually moving indicates that I'm trying to scroll).
When I choose to quit to restart my laptop (so far the only way I found
to get it all working again), I can't see any of the buttons in the
"Quit..."-dialog. When I hover the mouse over Suspend, Hibernate or
Restart, the buttons will appear (but nothing else). When I use tab to
jump between the selected button I can make all the buttons appear.
Don't know why the buttons redraw differently.
I'll give POST_VIDEO a spin... and I'll be back if it doesn't work ;)
Is POST_VIDEO considered a fix or just a workaround until the bug is
actually fixed?
Is there anything else I can do?
