Public bug reported:
Ubuntu screen freezes randomly. It seems that only screen freeze, but
system behind continue to work, including mouse. Using ctrl + alt + F1
and ctrl + alt + F7 resolves problem.
Freeze happen also if I use other than xorg driver. I tried all
available nvidia driver configurations.
I don't find relation between low or high cpu load.
