xorg log 

Hi.

I experience quite frequent freezes of the system since I've switched over to
nouveau... :(

This system here runs Debian unstable on AMD64, the GPU is a G86 [GeForce 8400M
G].

Symptom is that X suddenly freezes (although the system seems to keep running
in the back). Mouse continues to work, keyboard doesn't although SysRq is
possible to some extent (well sync/umount/boot).
Going back to console does not work.

I've attached an Xorg.log (although this didn't contain any errors).


Also some kernel log messages, collected from various events:

In this case, it apparently just killed my window manager, falling back to
metacity, and I could somehow cleanly reboot the system

(was just doing some libreoffice stuff,... so there shouldn't have been any 3D
problems included!?)



There usually follows some filesystem corruption from this...
Which makes the whole thing barely usable.


Not sure whether this is related, but I had some severe problems of freezing
nouveau, which seemed to be related with the system going out of main memory.
(Had several VirtualBox VMs started,...) This was quite easily reproduceable.



Any ideas? Or is there at least some way to certainly kill nouveau/X and go
back to a working console?


If you need further data, please tell me which.


Cheers,
Chris.

Hi Christoph

Would you mind removing the following package in order to establish if it's
related/triggers the issue

libgl1-mesa-dri-experimental

Note that by doing so your compositing manager will/should fallback to software
rendering (you will not have any 3d/GL hardware acceleration) thus your desktop
experience is not going to be as smooth

For future reference would you mind attaching the whole log (dmesg) rather than
pasting fragments of it in the report

Can you please take a look at our Bugs [1] and FAQ [2] section to eliminite one
of the most common root cause

Cheers
Emil

Hi.

>Would you mind removing the following package in order to

>libgl1-mesa-dri-experimental
I feared you'd ask this ^^...
Well I can give it a try, of course I'll loose compiz, which I'm particularly
used to... might very well happen that it doesn't happen without this.

>For future reference would you mind attaching the whole log (dmesg)
>rather than pasting fragments of it in the report
ok,.. that was just a huge mess... and apart for the usual log messages
detection the card/etc. there was not DRI related output at all.


I just hat the same(?) issue on a nother machine, with basically the same
software config but a G94 (Geforce 9600 GT) with two monitors attached.
But this time,.. no output to the logs at all. Neither xorg.log, nor kernel
log.
And even the SysRq messages made it into the syslog before the system rebooted.
This particular system shows also a very easily reproducable bug, but I'll
report that in a spearate bug report.


>Can you please take a look at our Bugs [1] and FAQ [2]
>section to eliminite one of the most common root cause
I've actually read them,.. but honestly,... some things you suggest there are
rather "difficult" (and I've studied computer science) for end users to do...
especially using git head for everything is quite an effort, especially when
you want to keep rather in sync with your distro.


Cheers,
Chris.

Oh btw: isn't it somehow possible to add functionallity if nouveau detects some
longer lasting lockup, that it kills itself,.. going back to some basic graphic
mode? Magic-sysrq + g seem to not work :(

This still persists basically.

Now with:
Linux 3.2.12
libgl1-mesa-dri/libgl1-mesa-glx 7.11.2-1
libdrm-nouveau1a 2.4.32-1
xserver-xorg-video-nouveau 1:0.0.16+g


One thing I've noticed:
It's possible to see the problems approaching (even when not looking at the
kernel output)...
The screen starts to flicker (especially when switching virtual desktops, due
to the compiz animation stuff) in some areas,.. if you then continue to work it
will usually freeze.
I've also noticed that closing windows (e.g. some terminals) usually helps then
and also stops the flickering.

When the freeze however happens, one has now usually a few seconds time to
Ctrl+Alt+F1 to the console and Ctrl+Alt+Enf or ACPI Power Button Event.
Thereby you at least shut down cleanly though still loosing all your work.

:-(

Hello,

I have the same problem: X freezes, mouse is working, keyboard does (mostly)
not work. But: I can still switch to console with Ctrl+Alt+F1 or sth like that. 

In my syslog i find messages like that:

Apr 25 14:27:05 foo kernel: [1390386.065164] [drm] nouveau 0000:0f:00.0: fail

My solution is then normally to restart gdm, then its working again (for some
time). Its absolutely not reproducable, for me its totally random occurance.

Some of my system settings:

I try to give any information you need! Thx for any help!

Does this still happen with recent software (kernel 3.11, mesa 9.2,
xf86-video-nouveau 1.0.9)? If so, please post fresh dmesg/xorg logs.
