Hi: For years I have run Fedora KDE with GeForce GT 710 and the
rpmfusion 470xx driver, using VGA and HDMI screens. A few weeks ago,
after some kde updates, I started seeing occasional brief pauses and
notifications of graphics resets in Kwin.
On the Fedora-kde list the suggestions are to change GPU hardware or go
to nouveau, with the benefit of a potential switch to Wayland.
I have tried to switch to nouveau using the rpmfusion nvidia howto
'Switching between nouveau/nvidia' but my grub menu no longer shows the
editable lines quoted. Editing /etc/default/grub instead, or with
nvidia and nouveau interchanged, loads nouveau but then unloads it and
leaves 470xx running as before. Log after one of the resets is:
[ 231.678] (II) NVIDIA(0): Setting mode "HDMI-0: nvidia-auto-select
@1360x768 +1680+0 {ViewPortIn=1360x768, ViewPortOut=1360x768+0+0},
VGA-0: nvidia-auto-select @1680x1050 +0+0 {ViewPortIn=1680x1050,
ViewPortOut=1680x1050+0+0}"
Help appreciated. Also an update of 470xx?
Thanks for the earlier history,
John P
It looks as if /etc/modprobe.d/nvidia.conf was the problem. It
blacklisted nouveau. Running now.
