And amazingly I do have a workaround! Well, for AMD/ATI users at least. If you have the proprietary AMD drivers installed, open up the Catalyst Control Center and switch over to the "Color" screen. Tweak the "Gamma" setting (make sure "All(locked)" is selected under "Select Color Channel:") and the screen should pop back into full brightness. Hit the reset button for that slider (off to the right-end of it) and it should stick.
I'm not sure if this is applicable to Nvidia users, or users without proprietary drivers. Nvidia users should definitely try this if they have their proprietary drivers and have access to their equivalent of AMD's CCC (don't remember what it's called for Nvidia cards). Non- proprietary driver users should look into installing Redshift (run "sudo apt-get install gtk-redshift") to graphically tweak the gamma settings. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1015297 Title: Screen partially darkened after suspend and resume in Xubuntu Status in pm-utils: New Status in Xfce4 Power Manager: New Status in Xubuntu: New Status in “fglrx-installer” package in Ubuntu: Confirmed Bug description: 3 days ago after the most recent kernel update, my computer wouldn't start and got stuck on the screen reporting that it couldn't detect the hardware and start X. I reinstalled Ubuntu and the Xubuntu desktop, and somehow I am no longer getting that error, but now whenever I suspend and resume Xubuntu, the whole desktop is darkened as if there's a layer of semi-transparent black over everything. The mouse cursor is still completely white, so I know it's not a monitor brightness issue. If I suspend and resume again, it's twice as dark, as if there are now two semi-transparent black layers over the screen. When I restart or log out and back in again, it's back to normal until I suspend again. It doesn't happen every time I suspend--just most of the time. I have no idea what package this is actually a problem with. It may have something to do with XFCE. I tried killing and restarting metacity and that didn't help, and neither did killing the screensaver.
