Problem Description

Disabling the internal LCD (e.g. when using an external Monitor) doesn't seem to work reliable.

  • i810switch doesn't have any effect. After disabling the LCD it is still on (but the status display of i810switch claims that is is switched off).
  • i855crt doesn't seem to allow to change the state of the internal LCD.
  • "echo lcd_disable >/proc/acpi/ibm/video" works, but "echo lcd_enable >/proc/acpi/ibm/video" doesn't work - so I can't enable it anymore after disabling it. (the strange thing is that when i switch to a console with ctrl-alt-f1 the LCD display is used for it, so there must be some way to enable it but I can't find out how to control this when using X). I've tried this with version 0.8 and version 0.11 of the "IBM ThinkPad ACPI Extras" driver.
