How do they compete? As I said, the implementations appear to be
implemented on top of the same underlying functionality. The problem
with providing both vendor and ACPI functionality comes when both use
different mechanisms for changing the backlight and so can get out of
sync with each other. Are there any machines supported by toshiba_acpi
where this is the case?
