Problems with lcd/dvi switching with ibm-acpi

Problems with lcd/dvi switching with ibm-acpi

[Andrey Kislyuk]

Hello,

I'm having problems switching between my LCD and minidock throughput DVI 
on an IBM Thinkpad T40 using ibm-acpi. DVI always shows up as disabled, 
and commands like "echo dvi_enable > /proc/acpi/ibm/video" are always 
ignored (as opposed to commands for switching between LCD and analog 
HD15). The system does boot fine using DVI if DVI was the active display 
device at boot, but then it can't switch to LCD.

This is observed on kernel 2.6.11 and 12 and all recent verisons of 
ibm-acpi. I'm sure this isn't anything related to X since it doesn't 
work when booting into a rescue CD console, either.

Any suggestions?

Thanks,
-ak
