[Ubuntu-x-swat] [Bug 849782] Re: Screen jitters every so often, especially when laptop under load
FWIW, I closed the upstream bug because my laptop's monitor quality has degraded even further. I've reproduced the jittering on boot and in the console. I'm solidly convinced it's a hardware issue. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/849782 Title: Screen jitters every so often, especially when laptop under load To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/849782/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Yeah, it's a momentary event and the glitch at the 9-10s mark is it. I'm afraid I don't have any better recording technology to hand. I've tried running the logs that you indicate, both with kms debugging and without. Nothing new comes up while the glitch occurs.

[Ubuntu-x-swat] [Bug 849782] [NEW] Screen jitters every so often, especially when laptop under load
Public bug reported: I have a Lenovo X200 laptop, and I run Unity 3D. Every so often, since oneiric, my screen jitters. That is, it seems to jump up and down like it has a nervous twitch. I can't reproduce it exactly, but it seems more likely to happen when my system is under load. I've monitored .xsession-errors when the twitch happens, and nothing is dumped there. I've also checked /var/crash/, but none of the crashes there have times that match the twitch. Chris Halse Rogers suggested trying, echo 0 /sys/module/drm_kms_helper/parameters/poll, but that doesn't seem to correct the problem. In addition, unity_support_test crashed while filing this bug.
