x log

I am unable to make the dual monitor setup work. One screen is attached over
HDMI, the other over DVI. Individually they both work fine. Once I attach the
second screen (DVI), it does not get signal and the HDMI screen shows both
screens in some weird squeezed format next to each other.

Depending on the settings in display preferences, I get various other weird
results when the desktop gets uncontrollable (does not react to mouse clicks
and keyboard events) so I have to restart the machine. After restart only the
HDMI screen appears, it shows content normally according to single screen
setup.
