I have a similar but different problem. When I lock my screen and come back, often times the screen will wake back up, but the dialog that normally appears to unlock the screen never appears. Sometimes I can go into virtual console and kill the screen saver daemon, and get back to my desktop, but it doesn't always work.
This is with the open source driver, and it's been a problem for quite a few releases for me. I'm trying the fireglx driver next, I seem to remember having other problems with that one in the past, but I'm desparate. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/800140 Title: radeon: [drm:drm_mode_getfb] *ERROR* invalid framebuffer id To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/800140/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
