FWIW, I've got a Dell Monitor and bug #1020221 is reporting this issue on a ThinkPad, so I don't think it's exclusively an Apple-hardware problem. You might be correct that it's a somewhat unusual setup.

Let me know if there's anything I can contribute. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1248256 Title: [MacBookPro10,1] Plugging in displayport monitor causes kworker to take 100% CPU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1248256/+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
