I'm running a triple monitor (2VGA, 1S-Video) setup off of two nvidia cards in Mint 11. Screen0 is working perfectly. Screen1 and Screen2 don't have window decoration, and clicking the "Show Desktop" button gives the message "Your window manager does not support the show desktop button, or you are not running a window manager."
CompizConfig Settings Manager recognizes all three screens in the upper-left dropdown box, but changes made with it set to Screen1 or Screen2 happen in Screen0.
I have tried adding
Option "AddARGBGLXVisuals" "True"
to the driver sections in xorg.conf, as that seemed to fix it when I was running the nvidia drivers and none of the screens were getting window decoration, but no dice. All of the panels and windows looked like some weird amalgamation of my theme settings and what appeared to be some sort of Windows95 inspired backup theme, and I still didn't have any window decoration.
Currently using the nouveau driver, and a modified xorg.conf file from nvidia-settings.
