Default Bug-Report for external CRT on laptop

The system is a SuSE 9.1 based kernel 2.6.6 with ACPI and the latest Nvidia-closed-source driver. When starting the laptop with BIOS-setting regarding displays set to AUTO it will select the external CRT for the startup messages. When starting X, X will crash, showing an empty screen. In the log you will find an oops of the nvidia-module (see below).
If the display-mode in the BIOS is set to both, the startup will be shown on both displays - but X starts on the internal display only.
Using "TwinView" Option does not change this behaviour.
The hotkey-display-switch does not function - I think it is only thought of working with APM?
When will we see an ACPI-suspendable version of the nvidia-module.

Cheers hartwig :-(

No, just checked. Also a reboot did only show the text-console on the external display.
When X started, I found out, that it did a

So X actually did not start, when booted with external CRT connected...

On the other hand I noticed, that ACPI debug showed me <4>[ACPI Debug] String: Length 0x1E, " ---- Ctrl+Alt+F5 switch ---- "
<4>[ACPI Debug] String: Length 0x0D, " SMI routine "
when I pressed the Fn+F5-display-switch-combination...

So maybe not all hope is gone, for the future.

Cheers :-/
