Title: XU 13.10 causing frequent laptop (acer 5620) hard lockups. Status in “xserver-xorg-video-intel” package in Ubuntu: New Bug description: since upgrading from LTS to XU 13.04 & then XU 13.10 the acer laptop is experiencing frequent hard lockups. one source of lockup has been GL screensaver, so I turned it off. Still the lockups happen Power management for AC is also off. The laptop does not run too hot, and the lid is up Is there a daemon that can catch the source of the lockups? I'm installing gnome system log viewer and are there log search terms to quickly find the trouble? I've checked the system with chkrootkit but it has a fatal flaw Checking `aliens'... /bin/egrep: /dev/.bootchart/proc/sysrq-trigger: Input/output error the same machine does not lock up under Linux Mint 15 MATE. kernel 3.8.0.xx Memory is tested often. 2GB Hard disk has no errors and is tested monthly System has been put through "crashme" and CPU intensive operations in order to raise tempurature, system remains stable. Most likely times of lockups are: - system left idle on AC and power manager is set to no suspend & GL screensaver activated (will lockup less often with no screensaver activated) - view webm or flash videos via browser and have more than ~ 800MB RAM usage - run glxgears full screen with some RAM usage resulting hard lockup shows venetian blinds effect on screen.
