I have a similar issue on my Thinkpad Edge 14 (Natty 32bit), when working in the Classic session.
Upon plugging in an external monitor [via HDMI], (or when booting with it plugged, after entering the session), the screen goes black (no mouse pointer either), with the external monitor picking no signal. When unplugging, the laptop has a non-functional black screen with a mouse pointer. The fix from [https://launchpad.net/~bryce/+archive/elderberry] did not help. [My symptoms match more closely those in duped #749817]. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
