Just an fyi: If the vga connected monitor is an lcd panel, they're known to sometimes hold onto a few frames to control overdrive ... If the difference in lag between the external screen and the laptop panel is big, that could be it.
Otherwise I don't think our scanout hw introduces an entire frame of lag, and X doesn't pageflip with multiple outputs, so that's no the 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/946311 Title: only external screen is working with asus zenbook ux31e [eDP1] To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/946311/+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
