I was having a problem with my screen resolution constantly changing on the fly while X was running with dual monitors.
Actually i am still having this problem but i think i figured out what was the trigger. It seems to happen only when my laptop starts to heat up when doing some CPU intensive tasks.
So i am wondering if there is such thing as a program that run in the background that tries to regulate heat or maybe the power management, that i could disable in order to get rid of the problem mentioned above. Maybe the unity equivalent of the gnome settings manager..
Thanks a lot for any help!
