THis log file shows the intel driver being loaded. Since I uninstalled the intel driver and have been running on VESA I have not had a single crash. Over a month now.
The log file attached is older (April) as I had saved it. I cannot revert to running the intel package right now as I have tasks running, but the log file is identical bar the date. ** Attachment added: "Old Xorg log." https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1367825/+attachment/4215884/+files/Xorg.1.log -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1367825 Title: Intel i915 video driver causing random crashes on i7 Z77 system Status in “xserver-xorg-video-intel” package in Ubuntu: Confirmed Bug description: Description: Ubuntu 14.04.1 LTS Release: 14.04 apt-cache policy xserver-xorg-video-intel xserver-xorg-video-intel: Installed: (none) Candidate: 2:2.99.910-0ubuntu1.1 System: Shuttle XPC SZ77R5 with 32 GB of memory installed (x4 8GB matched kit of sticks). Processor: Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz Kernel: 3.13.0-35-generic #62-Ubuntu SMP I am experiencng random lock-ups/crashes when using this system and the i915 video driver is active. This results in a fully corrupted screen and no ability to do anything. The only remedy is to restart the system by holding down the power button. I have tried a number of different ideas from different bug reports but they all seem to be different regarding the i915 driver. The screen corruption can be seen in the attached grab. My last resort to see if it was this driver being responsible was to remove it from the system and make use of the regular vesa drivers. I have been using the vesa driver for a week now with no further crashes. All memory sticks are confirmed as good. I have maxed out the memory running 8 different virtual machines to prove to myself there wasn't a bad stick of memory. Also memtest86+ does not show any faults. This problem has been apparent from kernel 3.2.x right up to not with 3.13.x installed. At various points I did test with kernels from Liquorix to see if the problem was resolved (or in the kernel at all). The crashes have happened in Gnome and KDE with different window managers which suggests it's related to xserver (driver). The crashes can come at any time under any kind of load. Sometimes just scrolling a window or entering some text. The only constant seems to be that something on the screen has to change. If left alone with no interaction the machine would run just fine. I have used it remotely with X forwarding without problem. This definitely seems to be an i915 issue, or something closely related to it. --- ApportVersion: 2.14.1-0ubuntu3.3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: crispy 3441 F.... pulseaudio CurrentDesktop: KDE DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=789ed600-1127-4ac3-9a63-1e8f187636f1 InstallationDate: Installed on 2013-01-06 (612 days ago) InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.5) IwConfig: vboxnet0 no wireless extensions. eth0 no wireless extensions. lo no wireless extensions.
