Title:
blinking blanking monitor
Status in “xserver-xorg-video-intel” package in Ubuntu:
Invalid
Bug description:
lsb_release -rd on AMD 64bit PC with
apt-cache policy pkgname
N: Unable to locate package pkgname
My display sometimes comes up as Dell 17" 1289 x 1024 and sometimes,
after an update, as Unknown 1200 x 800. In the Dell Case there are
lower resolution options that also display the blanking behaviour. In
the Unknown case, there is no other option.
When the Display comes up as Dell, it randomly blanks outfor usually
short (< 1 min) random periods.
When the display comes up as Unknown, it dos never blanks out, except
to sleep.
While this is similar to Bug #1011732,
echo 0x4 | sudo tee /sys/module/drm/parameters/debug
followed by
dmesg > monitor-blank.dmesg
..did nothing to remedy the situation
