Moving to Linux; this is a drm problem. This is fixed upstream, and should be in linux 3.2; Ben Skeggs has given me a list of the list of 13(!) (invasive!) commits that should fix this, but given kernel freeze is two days away this might not be appropriate for Oneiric.
Once git.kernel.org is back up I'll ask the kernel team to update the drm-next kernel build so you can check that it's actually fixed there. ** Package changed: mesa (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Mactel Support, which is the registrant for Mactel Support. https://bugs.launchpad.net/bugs/845137 Title: Second monitor doesn't work on MacBookAir3,1 with noveau driver (Experimental 3D support for NVIDIA cards) Status in Mactel Support: New Status in “linux” package in Ubuntu: Triaged Bug description: When plugging-in an external monitor on my MacBookAir3,1 using a Mini DisplayPort to DVI adapter my system freezes for a few seconds (screen doesn't update, can't type or move mouse, etc.) and the following errors are generated: Sep 8 16:41:55 Rico kernel: [22723.143036] [drm] nouveau 0000:02:00.0: plugged DP-1 Sep 8 16:41:55 Rico kernel: [22723.169853] [drm] nouveau 0000:02:00.0: unplugged DP-1 Sep 8 16:41:56 Rico kernel: [22723.589260] [drm] nouveau 0000:02:00.0: plugged DP-1 Sep 8 16:41:58 Rico kernel: [22725.770323] [drm] nouveau 0000:02:00.0: expected bit 16 == 0, got 0x01114000 Sep 8 16:42:06 Rico kernel: [22733.254017] [drm] nouveau 0000:02:00.0: unplugged DP-1 Sep 8 16:42:06 Rico kernel: [22733.565425] [drm] nouveau 0000:02:00.0: unplugged DP-1 Sep 8 16:42:06 Rico kernel: [22733.986777] [drm] nouveau 0000:02:00.0: plugged DP-1 Sep 8 16:42:08 Rico kernel: [22736.168598] [drm] nouveau 0000:02:00.0: expected bit 16 == 0, got 0x01114000 Sep 8 16:42:18 Rico kernel: [22745.373358] [drm] nouveau 0000:02:00.0: unplugged DP-1 Sep 8 16:42:18 Rico kernel: [22745.688777] [drm] nouveau 0000:02:00.0: unplugged DP-1 Sep 8 16:42:18 Rico kernel: [22746.107852] [drm] nouveau 0000:02:00.0: plugged DP-1 Sep 8 16:42:21 Rico kernel: [22748.289316] [drm] nouveau 0000:02:00.0: expected bit 16 == 0, got 0x01114000 Sep 8 16:42:26 Rico kernel: [22753.406729] [drm] nouveau 0000:02:00.0: unplugged DP-1 For as long as I keep the external monitor plugged-in the intermittent freezes and errors continue. In System Settings -> Displays clicking Detect Displays doesn't detect the external monitor. System recovers and acts normally when I unplug the external monitor. I had been using this monitor just fine daily for months with Natty and the nvidia proprietary drivers.
