tjaalton and bryceh suggested bisecting using the packages built from mainline rather than building from scratch.
Using <http://kernel.ubuntu.com/~kernel-ppa/mainline/> v2.6.39-rc1-natty when the external monitor is plugged in will _only_ use the external monitor; the monitors control panel apparently cannot even detect the internal monitor. If I unplug the displayport cable the internal screen is stuck black. v2.6.39-rc4-natty seems to work correctly. rc2 apparently failed to build. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
