> I've noticed that this is *not* happening in Unity or KDE. However, it *does* occur with both Xfce (known) and LXDE.
That indeed sounds related to 2D vs. 3D, but all of these desktops use a different window manager. So the bug could be anywhere between the Mesa and Linux layer. Alex mentioned that this could be a pm-utils bug. At least the original bug reporter is using fglrx, that should disable all pm-utils quirks. However, to make double sure that it's not that, can you please try the following: - Reboot your computer so that we are starting from a clean slate. - Open a terminal window. - Type "sync" and Enter - Type "echo mem | sudo tee /sys/power/state" and Enter; this should trigger a suspend - Wake the computer up again. Do you see the problem now? If so, please do the following: - Reboot your computer again. - Trigger a suspend by closing the lid or from the menu, etc. - Resume - Verify that you see the screen corruption now. - Attach /var/log/pm-utils.log Thanks! ** Changed in: pm-utils Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1015297 Title: Screen partially darkened after suspend and resume in Xubuntu To manage notifications about this bug go to: https://bugs.launchpad.net/pm-utils/+bug/1015297/+subscriptions _______________________________________________ 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
