xorg.0.log after resume
Comment 2 Matěj Cepl 2011-03-17 23:25:50 UTC 
Is this /var/log/Xorg.0.log from failed resume or from the correct one? If the latter, could we get the former and also could we get output of dmesg and /var/log/messages after the problem happens (from console or via ssh) and before you reboot?
Comment 3 Ben Skeggs 2011-03-30 22:53:34 UTC 
We still don't have the requested info and it's too late to do anything about it as an exception.  Moving to 6.2.
Comment 5 Ben Skeggs 2011-08-24 06:27:23 UTC 
Do you still see this issue with kernel-2.6.32-192.el6?
Comment 6 Martin Simon 2011-08-25 10:36:06 UTC 
I've reproduced that bug with latest kernel-2.6.32-192.el6l and nouveau xorg driver and got the same results. After resuming the laptop from suspend the screen stays blank. When I tried to dock the laptop to the docking station (with 2 screens connected), one of them woke up (while the laptop's screen still blank).
