The PGRAPH messages listed are harmless and do not cause your issues :)

Although there are a few things you can do

1. Find out which component did you update when the issue occurred
* The game, X, xf86-video-nouveau, mesa, kernel ?

2. Check if the software renderer produces the same result
* export LIBGL_ALWAYS_SOFTWARE=1 && savage...

3. Attach better logs
* http://nouveau.freedesktop.org/wiki/Bugs

Unfortunately I can't remember. I'd been using proprietary driver before today as I didn't get luck with nouveau.

Same result

> Same result

If X crashes while using the swrast (i.e. when LIBGL_ALWAYS_SOFTWARE is set), then the issue is not nouveau but mesa related.

If you're interested in getting this sorted you could track the package and commit that caused this :) Hint - seems like the package is mesa and/or xorg-server
Comment 4 Ilia Mirkin 2013-08-14 23:03:39 UTC
[  4863.494] (EE) Segmentation fault at address 0xde5

This is likely a simple null pointer dereference. Install the debug versions of the libraries (xf86-video-nouveau, mesa, X), and run X inside gdb (or just use gdb to look up where in the code it's dying based on the addresses it prints).

Not sure about the assertion that LIBGL_ALWAYS_SOFTWARE=1 + X crash = not a bug in nouveau. There's still the ddx...
