Xorg.log

Good morning,

I am using Debian testing nouveau driver and since an upgrade in nouveau driver
I am not able anymore to use it. Everything was working fine with Debian
nouveau driver 1:0.0.15+git20100329+7858345-5. Since I have upgraded to version
1:0.0.16+git20101210+8bb8231-2 or 1:0.0.16+git20110411+8378443-1 coupled with
kernel 2.6.38-3 on amd64 it is crashing in less than 10 seconds after the first
xterm is launched.

I am using 2 monitors. As soon as I place a window (xterm) on the secondary
monitor, the display becomes corrupted (2 monitors display the same image), the
mouse can move but everything else is frozen. I can use the SysRq key to
Sync,Unmount and Reboot.

I am using the following card:

You can try playing with WrappedFB (man nouveau), AFAIK it *does*
resolve similar issue on another Debian box.

Another option is to change/enable/disable xft fonts inside xterm.

How do you configure your dial head setup - xrandr of xorg.conf ?

Cheers

Funny, I also experienced corrupted second monitor after doing the same
upgrade. But not frozen graphics. Well I think it froze only once, and after
some time, so it was not easily reproducible.

After updating to latest git of everything (kernel, drm, ddx), I still got the
same corruption, and not a single gpu lockup. I just found one combination of
xrandr commands that would crash X every time, but no big deal.

Anyway as Emil said, I found many workarounds to my problem (if it's the
same)
:
- use wrappedfb in xorg.conf (which was the default before the upgrade)
- use xft to render fonts
- don't run xrandr settings before the wm

So I am curious to know how this would work for you.

I have been plagued with ?this bug for about a month; every time I loaded a
libreoffice component (calc or writer), the system lost track of the dual
screens, often putting a copy of the first screen up, then after a few more
seconds stopped accepting input from keyboard or mouse clicks (though pointer
moved I think). I don't know if SysRq worked because I use the box next door
to
reboot via ssh.

I'm using debian unstable amd-64 with nouveau 1:0.0.16+git20110411+8378443-1
and  a nVidia G98|GeForce 8400GS. I used a 3 line xrandr script in my bin
directory to enable dual screen after kde finished booting.

Thanks for the hints; the addtion of a minimal xorg.conf with wrappedfb in it
seems to have solved the issues for me.

(In reply to comment #2)

You are right. I created a simple xorg.conf file with WrappedFB set to
"on" and
it solved the problem.

> Another option is to change/enable/disable xft fonts inside xterm.
I haven't tried it as the first solution was working fine.
> How do you configure your dial head setup - xrandr of xorg.conf ?
I did not have any xorg.conf. The dual-head configuration was set up by gnome
using the "Screen" preferences. I believe it is relying on xrandr.

Many thanks for your help,

Antoine

It appears that this bug report has laid dormant for quite a while. Sorry we
haven't gotten to it. Since we fix bugs all the time, chances are pretty
good
that your issue has been fixed with the latest software. Please give it a shot.
(Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git
versions.) If upgrading to the latest isn't an option for you, your
distro's
bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs
that haven't seen updates since 2011. If the original issue remains, please
make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/
for what we need to see, and re-open this one.

Thanks,

The Nouveau Team
