Dear nouveau developers and users!
After many years of dealing with the blob in my kernel, I decided it was time
to move to an open source solution. With one of my machines, equipped with
9500GT it went almost flawlessly. I had to patch kernel to get GLXVBlank option
working (only because I used the latest and greatest 3.7-rc6), but that is all,
and I'm very happy with the result. Nouveau on that particular machine runs
really great!
But, after many hours of fighting I must ask for help with another machine,
which has 9600GT in it. I'm stuck on a very strange problem, where display
doesn't refresh (everything stops) until I move the mouse. Terminal with vmstat
1 in it stops refreshing, video stops, glxgears stops, everything. If I drag
mouse around frantically, screen refreshes normally.
Update:
- tried various kernel boot params (nohz=off, noacpi...) - didn't help
- tried putting known good 9500GT in - now that one won't work correctly
- tried booting older kernels to see if bug was introduced recently - nope
- tried upgrading libdrm & xserver-xorg-video-nouveau userspace parts -
didn't help (with mixed results, I also got some new errors :()
Finally, I concentrated on the specific X11 configuration I'm using
(should've done that earlier). I adapted it from the official
http://nouveau.freedesktop.org/wiki/MultiMonitorDesktop page, just
slightly simplified it, so I wasn't suspecting it until today.
I have two LCD's connected to the video card, one to DVI and the other
one to HDMI connector. They're configured as two X screens (:0.0 & :0.1)
one beside another (horizontally). And that part is what is causing
trouble. Having two screens! As soon as I comment out Screen 1
declaration in ServerLayout section, X becomes usable. But of course,
now I have only one screen and both monitors are displaying same content
which is not what I want.
I also noticed that I have /sys/class/drm/card0-HDMI-A-1, but I have to
use HDMI-1 (not HDMI-A-1) in the configuration, otherwise X segfaults. I
don't know if that's important.
Can anybody reproduce the bug? I'm attaching my full xorg.conf.
