Comment 11 for bug 98684

Well i have the same problem with my nvidia card (GeForce4 MX440) using restricted drivers and default in gutsy compiz-fusion. When I want to switch user, the screen goes to black and nothing happend. It seems that every thing is working in background - mpd is playing music. The only choice is to press ie. Ctrl+F1 (notice that screen is black) and press ctrl+alt+del to restart machine gently. Log's doesnt show anything interesting. Is there any solution for nvidia users?
I have tried to edit and set AlwaysRestartServer=true but this does not help!
