Not sure what happened. Had dual monitors working (compiz wasn't). Got compiz working. Yippee!

Then all of a sudden, my external monitor just stopped coming on when booting up. In the ATI Catalyst CC, the "2" monitor is greyed out.

output of xrandr -q:

I can post the xorg.conf if needed.

Anyone else have this happen? What other settings are there to look at?
