Title:
vblank wait timed out on crtc 0 after screen lock on Dell Latitude
e6220
Status in linux package in Ubuntu:
Confirmed
Bug description:
After a screen lock, the screen hangs, with the attached stack dump in
dmesg.
I've seen multiple bug reports with similar effect, but the workaround
has been "video=SVIDEO-1:d" as boot parameters, but this does not
affect my case. Also, the other reports, such as
https://bugs.freedesktop.org/show_bug.cgi?id=93782, includes
'intel_tv_detect' which mine does not.
