dmesg

One or both monitors (ASUS much more often) continously blink once in 5-10
seconds. This happens only in linux and not in grub or windows. Second problem
is that monitor layout resets to mirrored from extended desktop when monitor
returns from powersaving to show lockscreen and I need to rerun xrandr. There
are some errors in dmesg, so it is attached. Log is from right after returning
from being AFK and giving lockscreen password. This bug is continuation to my
previous problem in Bug #102300.
