To chime in here, as I mentioned above I have a newer Macbook (a MacBook7,1) and am still seeing this behavior running Oneiric with all the latest updates. More specifically:
1. I start my laptop with an external monitor connected. After I log in, the external monitor is still blank. 2. I run nvidia-settings and select X Server Display Configuration on the left. nvidia-settings shows both the laptop display and the external monitor. I select the external monitor and choose Configuration: TwinView. 3. I press Apply. The laptop display flashes briefly, but nothing else changes. The external monitor is still blank. 4. I press Apply a second time. Now I briefly see garbage on both displays. After a few seconds it goes away, and I see a dialog box on the external monitor asking me whether I want to accept the display change. I click OK. 5. Unfortunately, at this point Unity is no longer running (the sidebar and panel have vanished) and so I can't run any programs. I have to switch to a different terminal console and reboot. As a result, I can't use an external monitor with Ubuntu on this Macbook. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/845174 Title: Second monitor doesn't work on MacBookAir3,1 with nvidia-current driver To manage notifications about this bug go to: https://bugs.launchpad.net/mactel-support/+bug/845174/+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
