Subject: ACPI Toshiba-extras LCD backlight control not working anymore?
Date: Fri, 18 Oct 2002 15:28:38 -0700 [thread overview]
Message-ID: <200210181528.38731.EricAltendorf@orst.edu> (raw)
I can see the brightness levels:
[eric@localhost eric]$ cat /proc/acpi/toshiba/lcd
brightness: 5
brightness_levels: 8
but I cannot change them. Values echoed to the file are silently
ignored.
This used to work many versions ago (maybe 2.5.25, I don't recall).
It hasn't worked since 2.5.38, at least. Anyone know what happened?
Eric
