Gecko/20100204 SUSE/3.5.8-0.1.1 Firefox/3.5.8

I'm actually running a stable 11.2 userspace.

I upgraded to 2.6.34-rc3-7 kernel from OBS compiled for 11.2

All seems to be well until a leave the machine long enough for the monitor to
go to sleep.

When I try to wake it up, the monitor displays an error that the input is out
of the frequency range.

I have a pretty basic monitor hooked up. A CMV CT-723A and it only goes to
1280x1024 or so resolution, so it may be that the kernel is setting too high of
a resolution after waking up.

I haven't tried, but I assume I could ssh into the box at that point and do
some trouble shooting.

The 2 times it has happened I just rebooted.

Reproducible: Always

Steps to Reproduce:
1. Boot
2. log into X (KDE 4.4)
3. walk away for a while
4. Try to wake up the display by moving mouse
