I am also having the same issue (I have tested this with both Ubuntu 16.04 and Linux Mint 18. It did work with Windows 10.)
GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._gnome_2drr_2derror_2dquark.Code2: could not set the configuration for CRTC 65 When I try to enable a two external monitors in extended display. It does work as a mirrored display. If it helps I have a Lenova Ideapad Y580. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1409166 Title: Popup dialog "could not set the configuration for CRTC 65" steals keyboard, hinders login in 3-monitor configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1409166/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
