Odd. That's VPE. You should have one... maybe not. Nothing to worry
about though. (Especially odd that it's showing up multiple times --
are you trying to use xvmc?)
At the moment I'm trying nothing, its the default installation, i didn't
change something.
Where do I have to look to find it out?
Meh. Like I said, don't worry about it. On closer inspection, it's
most likely the nv31_mpeg_tile_prog function. Although why it's
getting addresses of 0... I don't know. (And also why it's getting
run, I don't know either. Something must be starting up either xvmc or
vdpau, the latter of which won't work for your card.)
Ok, if that is not my problem, so that doesn't matter.
Well, if compiz/something else *crashes* (i.e.
segfault/sigbus/whatever), it's likely there's a log of it. Perhaps
look in .xsession-errors, or run it inside gdb? Or are you saying that
you get a hard hang? Can you ssh into the machine when that happens?
Hm. I don't really know, i installed the ssh server not so i can test this.
but the last 'crash', the xserver was not possible to work on it any more,
just seeing horizontal stripes instead of a picture, let me go back to the
console and dmesg gives now additional:
[29361.912198] nouveau E[ PFIFO][0000:00:0d.0] CACHE_ERROR - ch 1

[29361.912206] nouveau E[ PGRAPH][0000:00:0d.0] ERROR nsource:

see the full dmesg:

After that i made a reboot, because a 'sudo service lightdm restart'
does something strange: I have an additional LightDM User there, which
is not there after reboot.... - but thats another problem. :)
