** Description changed: + [Copycat - A blackscreen can also appear due to a bug in the NVidia + Graphics Driver. (goto bug #573101)] + [Problem] 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] 1 Uninstall gnome-screensaver (see bug #555870 - something gnome-screensaver does is triggering this X bug) [Workaround] 2 Blindfold: Unlock session by typing password, then press <Alt>-<F2> (call "Run ..." dialog), then type "xgamma -gamma 1.0" and hit <Enter> [Workaround] 3 Update gnome-screensaver to 2.30.0-0ubuntu2 or higher (yet in proposed repo). Those versions are compiled with disabled "fade on lock".
