Public bug reported:
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
