I switched to metacity ( metacity --replace ), then connected the second screen (yes, it works!).
When I try to get back to compiz (compiz --replace), then I get the following error:
xset q doesn't reveal the location of the log file. Using fallback /var/log/Xorg.0.log
Detected PCI ID for VGA:

Checking for non power of two support: present.

This probably sums up the problem quite well.
