I tried disabled extmod in my xorg.conf, but with or without it, if I login (with compiz enabled) and switch to a text console and back, then I'm stuck on a blank screen and need a remote gdm restart doing.
In any case I find that a remote kill of the compiz.real process will unlock the vt lock and recover things pretty much (apart from compiz.real being dead stops doing its work)

username 11919 11894 3 21:24 ? 00:00:01 /usr/bin/ compiz. real --ignore- desktop- hints --replace ccp
kill -9 11919
in my case recovered it.
So the bug is in compiz.real, maybe?
I did an strace on compiz as I switched to a text console and back again
