I think the problem is that g-s-d assigns the first of the possible_crtcs without checking whether this crtc is already in use.
I guess g-s-d is assigning crtc 0 to VGA before unassigning it from LVDS. An additional check when assigning crtc would have made g-s-d assign crtc 1 instead. Note: outputs can share the same crtc in clone mode -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/791752 Title: Can not toggle Display to External only mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/791752/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
