Description Dave Mitchell 2008-04-22 21:46:26 UTC 
Description of problem:

After resuming from a suspend, the screen is blank (although still backlit).

Version-Release number of selected component (if applicable):

xorg-x11-drv-i810-2.1.1-7.fc8

How reproducible:

Steps to Reproduce:
1.Suspend to memory
2.resume 

  
Actual results:

screen is blank

Expected results:

lock window

Additional info:

There is a workaround: doing Ctl-Alt-F1 then Ctl-Alt-F7 unblanks the screen;
this is not a full workaround however, as the console on Ctl-Alt-F1 remains
blank (no login prompt visible, but backlit)

I think I have the same problem here, with a laptop with an Intel 915 chipset,
with Fedora 9 preview. At first, the screen didn't turn back on, I had to add
the following line to /etc/pm/config.d/local:

DISPLAY_QUIRK_VBE_POST=true

Now, the backlit turns back on, but everything else is frozen. Ctrl-Alt-F1
doesn't work, I have to Alt-SysRq-S, U, B to reboot the notebook.

Changing version to '9' as part of upcoming Fedora 9 GA.

I haven't seen this problem on my F8 laptop for a couple of months now, so I assume a yum update at some point made the problem go away :-)
