Re: X server segfaults: GPU lockup - switching to software fbcon

The most suspicious message is, I think:
[    3.782463] [drm] nouveau 0000:01:00.0: GPU lockup - switching to software fbcon

Re: X server segfaults: GPU lockup - switching to software fbcon

I will be grateful for any clues. Thanks.

And I have a slight idea, that it happened after a systemd recent update (from 188 to the current one).

I am having this same issue. Has anyone found a solution yet, besides using the proprietary drivers?

Re: X server segfaults: GPU lockup - switching to software fbcon

Is a bug open for this issue ? I couldn't find it on the bug tracker ...

I just downgraded to kernel 3.4.6 to keep KMS and nouveau working.

EDIT: I finally found it: https://bugs.archlinux.org/task/30840
and its upstream report: https://bugs.freedesktop.org/show_bug.cgi?id=52244

Re: X server segfaults: GPU lockup - switching to software fbcon

The issue has been closed.
Solution : use kernel 3.6 or linux-nouveau-git if you need a 3.5 kernel (until linux-nouveau is updated accordingly)

For information, my gfx card is an nvidia gtx 560ti
