Here comes another "me too" message. I'm experiencing the same bug. Dell Studio 1558 (AMD Radeon HD standalone graphics adapter) with (K/X/L)ubuntu 12.04. I'm currently using proprietary drivers.
This bug had occurred on this machine before (I think in 11.04 or 11.10), but I figured it was a one-time bug. Now it's happening again for no discernible reason. Like others, it's happening when opening the laptop's lid (in my case to resume, though it sounds like it's not limited to resuming). Mouse is still at full brightness. I haven't tried logging off yet (my screen's still dimmed right now); I'm putting that off so I can save all my work. I don't think the card specifically is the issue (since it's affecting AMD and Nvidia chipsets alike), but I'm going to test things like compositing and what not to see if I can force some kind of workaround. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
