Public bug reported:
Binary package hint: xserver-xorg-video-intel
Hi,
after resuming from Suspend2RAM on a Dell Latitude D620 I get colorful
garbage on the screen and the output freezes. I still can shutdown the
notebook using the power button and login through ssh, but the screen is
not to revive (not with ctrl-alt-backspace either).
I think this behaviour is pretty new, I can't tell for sure but I think
I see this happening since the upgrade to 2:2.2.0+git20080107-1ubuntu1.
/var/log/Xorg.0.log (attached) shows the lines
(WW) intel(0): PRB0_CTL (0x0001f001) indicates ring buffer enabled
(WW) intel(0): PRB0_HEAD (0x00000000) and PRB0_TAIL (0x00000008) indicate ring
buffer not flushed
(WW) intel(0): Existing errors found in hardware state.
at the end
