Hi David,

>From a terminal in an x-session, you can start a program called
"glxinfo" and search the output for error messages. Running "glxinfo"
usually unveils errors related to graphics and rendering.

You can get a decent text terminal by pressing Ctrl+Alt+F2 from a
running x-session. Log in.
Run "aptitude search compiz beryl | grep ^i" to see if there are any
components of compiz/beryl installed. If there's no output, you can be
certain that neither compiz nor beryl are installed.
Pressing Alt+F7 brings you back to X.

I haven't been in contact with compiz/beryl, so what comes next is guessing:
Is there perhabs a setting in /etc/X11/xorg.conf that's not
corresponding to your system (Driver, module, frequencies)?
Is there perhabs a /etc/defaul/compiz|beryl.conf ?
