I have a Dell Inspiron M5010 and I am unable to change my backlight brightness with the F-Keys and it also does not work with gnome brightness widget.
I am able to change backlight brightness manually on the terminal with
$ sudo -s
$ cd /sys/devices/virtual/backlight/dell_backlight
$ ls -la
insgesamt 0
drwxr-xr-x 3 root root 0 2012-04-06 13:03 .
drwxr-xr-x 3 root root 0 2012-04-06 13:03 ..
-r--r--r-- 1 root root 4096 2012-04-06 13:17 actual_brightness
-rw-r--r-- 1 root root 4096 2012-04-06 13:17 bl_power
-rw-r--r-- 1 root root 4096 2012-04-06 13:03 brightness
-r--r--r-- 1 root root 4096 2012-04-06 13:03 max_brightness
drwxr-xr-x 2 root root 0 2012-04-06 13:17 power
lrwxrwxrwx 1 root root 0 2012-04-06 13:03 subsystem -> ../../../../class/backlight
-rw-r--r-- 1 root root 4096 2012-04-06 13:03 uevent
$ echo 8 > brightness
Can I configure gnome power manager to use the right files somehow?
