My video card has worked fine with recent builds of the f23 nvidia304xx driver from rpmfusion, but an update two days ago left me with black screens (two - VGA and HDMI). I have a thread on the rpmfusion list, but here may now be more appropriate.
I have removed the nvidia packages, and nouveau gives me the full plasma window with taskbar etc, but after a few seconds that is replaced by featureless black screens with a mouse arrow that moves - from one screen to the other - but does nothing else.
Ctrl/Alt/F2 lets me view Xorg.0.log - on both screens - and all looks harmless until, about 80 seconds after the last NOUVEAU message, about HDMI max frequency, I get
AIGLX: Suspending AIGLX clients for VT switch NOUVEAU(0): NVLeaveVT is called
It now looks as if this is just recording the switch to tty2
Switching between Ctrl/Alt/F2 and Ctrl/Alt/F1 adds more instances of it but I still don't get a working GUI
Ideas?
