One workaround is to use the User Switcher panel applet, instead of the Indicator Applet Session. For some reason, the Indicator Applet Session dims the display before switching; when you come back to that user's session, you either get a dimmed screen (which you can fix with "xgamma -gamma 1.0") or a completely black screen, which I've have to reboot from.
The User Switcher returns you to the main login screen, instead of the windowed user switch from Indicator Applet Session. -- [RS480] black screen after a few user switches https://bugs.launchpad.net/bugs/546578 You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xserver-xorg-driver-ati. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
