I'm experiencing similar problems with an Radeon HD 6700 graphics card: After resuming, I see the mouse pointer, but the unlock screen does not appear. In fact, it seems to be rather invisible but still active, as I am able to enter my password and unlock the screen blindly.
Switching to an text console, playing with xrandr and switching back results in screen corruption. Killing the X server with sysrq-k brings back an lightdm login screen (but obviously kills my session). -- 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
