Public bug reported: This machine is the newest Macbook Pro. When I plug in an external monitor (VGA or DVI), the system does one of two things:
- system freezes (mouse can be moved), but can be rescued with ctrl-alt-f1 and gdm restart - system hardlocks, SSH connections to the machine die ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: linux-image-2.6.38-8-generic 2.6.38-8.42 ProcVersionSignature: Ubuntu 2.6.38-8.42-generic 2.6.38.2 Uname: Linux 2.6.38-8-generic x86_64 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.23.
