Yes, you may be right. I just think that it's remarkable that it's the exact same display configuration that fails in (almost) the same way as the bug description. All other display configurations I've tried works fine, including mirror, dual and only internal.
What doesn't fit into the bug description is that I don't get the timeout where the display is reverted to the previous configuration. Maybe I'll try a newer kernel later. @Chris: So you don't get the same kind of errors in syslog as I get when you reproduce this bug? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/828623 Title: [Regression] gnome control centre does not allow you to disable the laptop screen while leaving an external DisplayPort connected screen working To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-control-center/+bug/828623/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
