Bug Description
Up-to-date Lucid with radeon driver. After switching user a few times (usually between 3 and 5 times), the screen goes black with only the mouse cursor visible after entering the user's password. VTs are also completely black. Restarting gdm fixes the issue, and nothing odd appears in XOrg.0.log when the black screen occurs. It also happens with KMS disabled. It also happens with compiz disabled for all users.
WORKAROUND: Uninstall gnome-screensaver (see bug #555870 - something gnome-screensaver does is triggering this X bug).
WORKAROUND: Blindfold: Unlock session by typing password, then press <Alt>-<F2> (call "Run ..." dialog), then type "xgamma -gamma 1.0" and hit <Enter>
WORKAROUND: Update gnome-screensaver to 2.30.0-0ubuntu2 or higher (yet in proposed repo). Those versions are compiled with disabled "fade on lock".

I have experienced the same thing on a fully updated Lucid with an ATI Radeon Xpress 200m video card. I can switch from the primary user to a secondary user just fine, however, attempting to return leaves me with a black screen and only a mouse.
