I had recently installed 8.04 and got Compiz and AWN working wonderfully however last night I plugged my laptop into the TV to watch a movie and the screens started distorting the image so I rebooted and disconnected the secondary monitor.

Now when I boot up Compiz and consequentially AWN stops working. I try starting Compiz up manually but I get this error in console:

alex@alex-laptop:/usr/bin$ sudo compiz
Checking for Xgl: not present.
