Trying to use nouveau in plasma and f23

[John Pilkington]

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?

The final two lines of dmesg are

show_signal_msg: 9 callbacks suppressed

plasmashell[1901]: segfault at 0 ip 00007fcabe9244a7 sp 00007ffd195bf9c0 
error 4 in nouveau_dri.so[7feabe49a000+8ce000]

These occur at 205s.  The HDMI max TDMS frequency message in Xorg.0.log 
was at 165s.

All messages copied manually from the screens.

What happens if you purge all of nouveau and NVidia drivers, leaving Xorg to
use its integral modesetting driver?

Thanks for the suggestion.  I wasn't hopeful, having tried removing the 
intel driver (with an old i915 chip) in *this* box running SL7, but 
tried it:

dmesg | grep segfault gives 7 lines:

sddm[xx]: segfault at 0 ip xxxx sp xxxx error 4 in libQT5Core.so.5.6.1[xxx]

or similar but with error 14 in sddm.

dnf history shows that 58 packages were updated on 10 Oct, but that 
would be with yumex-dnf and I can't find where it stores its history for 
non-GUI access.

I had previously tried the nvidia build from scrpms, which didn't 
install cleanly (rpm -i --force) but also pointed to libQT5Core.so.5.6.1

I have to update.  There were still nvidia*-libs packages installed.

Now the first 4 segfaults are in sddm, error 14, 15, 15, 14.  The ones 
after that are in sddm .... libQT5Core.so.5.6.1

SOLVED Trying to use nouveau in plasma and f23

[John Pilkington]

Further attempts to install xorg-x11-drv-nvidia-304xx once more failed 
to build the kmod.  After dnf remove-ing it and checking that rpm -qa | 
grep nvidia returned nothing, dnf install xorg-x11-drv-nouveau has 
brought back a working system.

Sorry for the noise.
