Lacking resources to do full kernel commit bisect, "adjacent" kernels in the order of http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D
we have last good kernel v3.19.8-ckt9-vivid/ first bad kernel: v4.0-rc1-vivid/ kernels tested: 3.19.8ckt4 3.19.8ckt7 3.19.8ckt9 4.0.5 4.0rc1 4.1.2 4.2.1 4.2.5 4.3rc7 I take it all back... As I was working on my WebGL code just now it crashed again. I've attached my Xorg.2.log which clearly shows a problem: [ 1329.968] (WW) Falling back to old probe method for vesa [ 1332.117] (EE) intel(0): [drm] failed to set drm interface version: Permission denied [13]. [ 1332.117] (EE) intel(0): Failed to claim DRM device. [ 1332.117] (II) UnloadModule: "intel" [ 1332.117] (EE) Screen(s) found, but none have a usable configuration. [ 1332.117] (EE) Fatal server error: [ 1332.117] (EE) no screens found(EE) [ 1332.117] (EE) Please consult the The X.Org Foundation support at http://wiki.x.org for help. [ 1332.117] (EE) Please also check the log file at "/var/log/Xorg.2.log" for additional information. [ 1332.117] (EE) [ 1332.142] (EE) Server terminated with error (1). Closing log file. What's up with that permissions error? Also, why is it even getting such an error so late after running just fine for hours? ** Attachment added: "Xorg.2.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1509556/+attachment/4509620/+files/Xorg.2.log -- You received this bug notification because you are subscribed to the bug report. https://bugs.launchpad.net/bugs/1509556 Title: Kubuntu Wily upgrade screen glitch with 4.2 kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1509556/+subscriptions -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1509556 Title: Kubuntu Wily upgrade screen glitch with 4.2 kernel Status in linux package in Ubuntu: Incomplete Bug description: On recent update from 15.04 to 15.10, the new 4.2 kernel is associated with graphics instability after a few seconds of GUI use with mouse and keyboard making the GUI unusable. See another person's same experience with intel graphics here: askubuntu.com/questions/688649/kubuntu-wily-upgrade-screen-glitch Downgrading to the last 15.04 kernel solves my issue.
