Here on a PowerMac G5 with a NVIDIA GeForce 6600LE graphics ca=
rd, most things
run pretty well except for some of the things I wanted to run on the machine
resulted in nouveau GPU lock-ups, and consequently a glitched display
(artifacts only).
When trying to start GDM, SDDM, or Plasma Desktop on the machine, the displ=
ay
locks up, and I was able to salvage an error message as follows:
[drm] nouveau 0000:0a:00.0: GPU lockup - switching to software fbcon
After a minute or two, the display responds again, but only showing a black
background with several randomly colored pixels, and some white blocks.
However, this graphics card runs LightDM, XFCE, MATE... and most other
applications without such error and lock-ups. I was able to workaround the
issue by using the nouveau.noaccel=3D1 kernel parameter (except in the case=
of
GDM, it returned with the same error), but that simply beats the purpose of
owning a graphics card.
However, even with the noaccel parameter in place, I was still experiencing=
bad
coloring issues, as reported here:
https://bugs.freedesktop.org/show_bug.c=
gi?id=3D98630.
----------
Some version info:
- Linux Kernel 4.8.6 (with 4K paging in case you are wondering)
- Mesa 13.0.0
- Xorg Server 1.18.4
----------
P.S.
I tried on with a Quadro FX4500, which simply shows the lock up error whene=
ver
attempting to start X. But I couldn't make sure if it's a hardware issue or
not, as the card sparked on the first power up, that's why I have already
returned it...
