Re: xbacklight on intel

Yeah, please file a bug. In the meantime, you can
add '/sys/class/backlight/fujitsu' to the list of backlight directories
in i830_lvds.c then rebuild your driver to make sure it'll work for
Here's that bug: https://bugs.freedesktop.org/show_bug.cgi?id=14706.
And I've attached the tiny patch against the intel driver that fixes this for me.
However, there is one little issue left. If I change the backlight using the hardware controlled function keys, xbacklight -get still returns what it had set itself previously. This seems to be because /sys/class/backlight/fujitsu-laptop contains one file called 'brightness' and one called 'actual_brightness'. 'actual_brightness' is read-only, and echoing a number to 'brightness' changes the backlight brightness as well as 'actual_brightness' properly. However, when changing the backlight through the function keys, only actual_brightness changes.
Thinking of it, this might be a bug of the fujitsu-laptop kernel module... not sure.
