Sorry for the delay in follow-up: Yes, the patch when cherry-picked into a recentish mainline kernel shows noticable improvement. Subjectively, it still feels a little "chunky" when starting up (I think the login manager and gnome 3 both seem to issue a large number of xrandr requests), but night and day compared to the previous succession of stalls.
w.r.t. bug 29536? I can't say whether it's a dupe or not. i specifically wasn't getting the periodic stalls every 10-30s. But perhaps the other reporter had something that was doing xrandr requests with that frequency whereas for me it was only during log-in. -- 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/855124 Title: XRANDR operations very slow unless (phantom) HDMI1 disabled To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/855124/+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
