Problem Description
Problems with Intel chipsets
Disabling the internal LCD (e.g. when using an external Monitor) doesn't seem to work reliably.
- 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.
- With ibm-acpi,
# echo lcd_disable >/proc/acpi/ibm/videoworks, but# echo lcd_enable >/proc/acpi/ibm/videodoesn't work - so one can't enable it anymore after disabling it. (the strange thing is that when switching to a console with ctrlaltF1 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 in X). I've tried this with version 0.8 and version 0.11 of ibm-acpi.
Problems with ATI chipsets
- It is a known issue of xorgs radeon driver that FnF7 doesn't work.
