Kernel log.

Ubuntu 14.04.2 with 3.19.2 mainline kernel and utopic graphics stack.

I had been plugging my Acer C720 into monitor already couple times during the
day before this happened. Connected laptop to monitor again. Gave xrandr
command to turn on hdmi and turn off lcd. X restarted. Realized later on that
there were traces in kernels and X servers log.
