Comment 50 for bug 760632

Also reproducible on Lubuntu 11.04 in lxterm. Switching back and forth between a TTY (which will be just a black screen) and X coated with a little patience sugar will bring back interaction (just did it while writing this). Don't know if this is due to lxdm being more stable than gdm and kdm, or just my luck, but that's how it "works" in LXDE :) Doesn't seem to happen with other windows, though (Chromium or File Manager, although the latter may a resize corner that won't function). Strange that it's terminal related, across gnome-terminal, konsole, and lxterm...?!?!?!

Gonna try Szymon's workaround, thanks for that!

Hopefully the nvidia folks will have a proper fix soon.
