[ltp] switching display

Thank you!

The affected Thinkpad is a T20, Kernel 2.6.24.3

        modprobe ibm_acpi

produces "/proc/acpi/video" and "/proc/acpi/ibm" with many entries on my  
T20; on my T40 I see only "/proc/acpi/ibm".

        cd /proc/acpi/ibm
        echo auto_enabled > video
        echo crt_enabled  > video
        echo lcd_disabled > video

switches the LCD off, and now I can again switch with "fn f7".

I'll look for the "auto" status the next time the machine won't switch.


Viele Gruesse!
Helmut
