Red Hat Bugzilla – Bug 213593
Suspend not re-initializing i855GM or i945GM properly
Last modified: 2007-11-30 17:11:47 EST
On my Sony Vaio PCG-TR3AP3, suspend-to-RAM was working fine on FC6test3 but it
no longer works on FC6 final. When the laptop resumes from being suspended, the
screen turns white with irregular dark borders, and it gradually fades into
white. (I've seen this weird "feature" of X on a number of machines with
wrongly-configured X servers... what is this anyway?) I will attach three
photos of the screen as it progresses towards white. (Sorry for the poor photo
Everything but X seems to come up fine, and pressing the power button initiates
a shutdown etc.

PS fading to white takes something on the order of 10 seconds or so. I don't
think this is a chipset thing, I have seen it on nVidia chipsets too. The
chipset on this laptop is an i855GM.
I've got a Dell XPS M1210 with Intel 945GM graphics and while I don't get the
white screen, I don't get any video on resume. System resumes fine and I can hit
the power button for a clean shutdown but I don't get video. Switching to a
virtual console doesn't show anything either but after hitting the power button,
I do get virtual console output while the laptop shuts down.
Changing the summary, I realized I put i810 rather than i845GM in the first
place, and as the 855 is related to the 945, I put that in there too...
PS I would like to help fix this problem, but I actually need to sell this
laptop in about a week. I am willing to try anything before then to help
diagnose and fix the problem, if any knowledgeable kernel/X hacker can point me
in the right direction before then. In about a week's time I won't be able to
do any hands-on debugging. Sorry, I didn't know I was selling the laptop when I
filed the bug.
