I'm using gutsy and it doesn't appear fixed to me... Though this might be a slightly different problem:

Log in as A, just like normal.
Switch user, log in as B
Log out B.

It should then go back to the A login, asking for the password, but instead the machine locks up hard, with no cursor visible. The screen is mostly black, but with white stippled squares, about half of which are blinking. Looks like some video corruption in a text mode. I have to power-off to get it to do anything.

This is on a thinkpad x60s, with the intel xorg driver. No desktop effects (they stopped working entirely a while ago... not sure why - I just get "desktop effects could not be enabled" when I try to turn them on, and a "No GLXFBConfig..." error in xsession-errors)
