The originally reported "[TTM] Failed to expire sync object before buffer eviction" smell like a kernel issue too, and probably one that's fixed in upstream kernel. They don't show up when I boot into today's kernel.org's 3.11.0-rc7 (commit a8787645e14ce), and are probably fixed by recent drm/noveau changes since 3.11.0-rc6
My original issue seems to have gone away when I realised that box was using lightdm, not gdm, and lightdm is no longer supported. If I see problems when reverting to ubuntu standard kernel, while keeping gdb, I'll re-raise against kernel. So this is just Fabio's issue -- apologies for conflating the two when "failed to expire sync" seen -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1208207 Title: driver crash Status in “xserver-xorg-video-nouveau” package in Ubuntu: Confirmed Bug description: Hallo It works well till greeter and the firsts minute of the session, then became instable and then crash, mouse mouving but graphic garbled. tty works ProblemType: Bug DistroRelease: Ubuntu 13.10 Package: xserver-xorg-video-nouveau 1:1.0.8-0ubuntu1.1 ProcVersionSignature: Ubuntu 3.10.0-6.17-generic 3.10.3 Uname: Linux 3.10.0-6-generic x86_64 ApportVersion: 2.12-0ubuntu2 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' Date: Mon Aug 5 00:49:20 2013 DistUpgraded: Fresh install DistroCodename: saucy DistroVariant: ubuntu ExtraDebuggingInterest: Yes, including running git bisection searches GraphicsCard: NVIDIA Corporation C51G [GeForce 6100] [10de:0242] (rev a2) (prog-if 00 [VGA controller]) Subsystem: ASRock Incorporation Device [1849:0242] InstallationDate: Installed on 2013-08-04 (0 days ago) InstallationMedia: UbuntuKylin 13.10 "Saucy Salamander" - Alpha amd64 (20130803) Lsusb: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 002: ID 046d:c050 Logitech, Inc.
