Public bug reported: Dual Screen not working on 14.04 when I log in today. Get error message:
Failed to apply configuration: %s GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._gnome_2drr_2derror_2dquark.Code2: could not set the configuration for CRTC 63 Yesterday I applied updates. Ubuntu software history shows these as: bsdutils(2.20.1-5.1ubuntu20.2,2.20.1-5.1ubuntu20.3) xserver-xorg-video-intel(2.99.910-0ubuntu1.2,2.99.910-0ubuntu1.3) Previous to this I have had no problems with dual screen on 14.04. Solved this by reverting back to the Nouveau driver rather than using the recommended proprietary driver under the Softwares &Updates>Additional Drivers link. The recommended nvidia proprietary driver (version 331.38) previously worked but doesn't work after the above Ubuntu updates. Graphics card used GeForce GT 540M. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1394189 Title: nvidia proprietary driver stopped working after ubuntu updates from 18 November 2014 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1394189/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
