>From your logs it looks like the problem is that something is probing the VGA output repeatedly, and you're the lucky owner of some hardware that flickers when probed (it's not uncommon).
You could check this by adding “drm_kms_helper.poll=0” on the kernel command line; that should disable polling on the VGA (and, indeed, all other) output. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/747069 Title: [natty beta-1] Screen flashes on and of every few seconds with nouveau driver _______________________________________________ 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
