Public bug reported: On either docking or undocking my X40, the laptop display is corrupted, and cannot be recovered. External VGA continues to function, but cursor is invisible.
To reproduce: * Either * Boot in dock, then hit Fn+F9 (ACPI undock) OR * Boot undocked, then dock - At this point the laptop LCD is corrupted (mostly black, some white lines that seem to move with the cursor), and there is no signal to the external VGA (dock connector, laptop connector is inaccessible in dock). * Next, hit Fn+F7 (ACPI video) - Now the external VGA fires up, at laptop display resolution (1024x768), however the cursor is invisible, but still functional (exactly as for Bug #614176) Bug still present in 2.6.35-23.35~pre201010220901, appeared sometime after 2.6.35-19.25~lucid1 ProblemType: Bug DistroRelease: Ubuntu 10.10 Package: linux-image-2.6.35-22-generic 2.6.35-22.35 Regression: Yes Reproducible: Yes ProcVersionSignature: Ubuntu 2.6.35-23.35~pre201010220901-generic 2.6.35.7 Uname: Linux 2.6.35-23-generic i686 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.23.
