This is worse than I originally thought. It happens when using GNOME's menu to switch user in addition to the Ctrl + Alt + FX keys. The kernel does not crash as I can continue communicating with the computer over the network. This makes a multi user desktop unusable in any practical way. For that reason I am bumping the severity. I believe this bug is triggered during KMS switching. This has been mentioned on test list a few days ago. Happens for me with an up-to-date F18, too. Sometimes the switch to virtual console succeeds, in other cases the screen turns black, monitor loses signal, and repeated attempts to switch back and forth don't fix that. [...] Xorg.0.log only mentions: [ 2100.836] (II) AIGLX: Suspending AIGLX clients for VT switch [ 2101.371] (II) AIGLX: Resuming AIGLX clients after VT switch There is a flood of log messages afterwards (this block of lines a few times per second): Dec 21 19:11:11 noname kernel: [ 2101.372110] [drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation -35!

Created attachment 654748 [details] Xorg log Description of problem: There are normally two users logged into GNOME 3 simultaneously. Switching between these two users using Ctrl + Alt + FX will sometimes cause the display to go black. When this happens, the monitor displays "no signal going to sleep". It appears as there is no video signal. This does not happen with every switch, but frequently enough to happen daily. Once this occurs, I am unable to recover the video without a restart.
