Apparently the modesetting driver doesn't play well when trying to set the primary output (which does not seem to be supported by the driver).
In any case, we should really make sure to trap the XError and to ignore it when setting the primary output, instead of only ignoring the error when we look for the primary output. This solves the problem in libgnome-desktop. ** Also affects: gnome-desktop-3 (Ubuntu) Importance: Undecided Status: New ** Changed in: gnome-desktop-3 (Ubuntu) Assignee: (unassigned) => Alberto Milone (albertomilone) ** Changed in: gnome-settings-daemon (Ubuntu) Status: Triaged => Invalid ** Changed in: gnome-desktop-3 (Ubuntu) Status: New => In Progress ** Changed in: nvidia-graphics-drivers-319 (Ubuntu) Status: Triaged => Invalid ** Changed in: gnome-desktop-3 (Ubuntu) Importance: Undecided => High ** Changed in: gnome-settings-daemon (Ubuntu) Assignee: Alberto Milone (albertomilone) => (unassigned) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-modesetting in Ubuntu. https://bugs.launchpad.net/bugs/1224254 Title: xrandr Xerrors with the nvidia binary drivers (optimus) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-desktop-3/+bug/1224254/+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
