This might be fixed in the upcoming upstream 3.20 kernel - see http://lkml.iu.edu/hypermail/linux/kernel/1502.2/02418.html

I tried to adjust the brightness on my Toshiba Portege M100 by pressing Fn + F6/F7. Unfortunately nothing happened. "toshiba_acpi" is loaded and "acpi_listen" gives me the following on pressing Fn + F6/F7: # acpi_listen hkey VALD 00000000 00000140 hkey VALD 00000001 00000140 hkey VALD 00000000 00000141 hkey VALD 00000001 00000141 Running "acpid -d" gives me the following output by pressing Fn + F6/F7: # acpid -d acpid: received event "hkey VALD 00000000 00000140" acpid: rule from 4077[0:0] matched acpid: notifying client 4077[0:0] acpid: rule from 4021[105:106] matched acpid: notifying client 4021[105:106] acpid: 2 total rules matched acpid: completed event "hkey VALD 00000000 00000140" acpid: received event "hkey VALD 00000001 00000140" acpid: rule from 4077[0:0] matched acpid: notifying client 4077[0:0] acpid: rule from 4021[105:106] matched acpid: notifying client 4021[105:106] acpid: rule from /etc/acpi/events/tosh-video_brightnessdown matched acpid: executing action "/etc/acpi/video_brightnessdown.sh" BEGIN HANDLER MESSAGES END HANDLER MESSAGES acpid: action exited with status 0 acpid: 3 total rules matched acpid: completed event "hkey VALD 00000001 00000140" acpid: received event "hkey VALD 00000000 00000141" acpid: rule from 4077[0:0] matched acpid: notifying client 4077[0:0] acpid: rule from 4021[105:106] matched acpid: notifying client 4021[105:106] acpid: 2 total rules matched acpid: completed event "hkey VALD 00000000 00000141" acpid: received event "hkey VALD 00000001 00000141" acpid: rule from 4077[0:0] matched acpid: notifying client 4077[0:0] acpid: rule from 4021[105:106] matched acpid: notifying client 4021[105:106] acpid: 2 total rules matched acpid: completed event "hkey VALD 00000001 00000141" So my first guess was to add the keycode in "/etc/acpi/events" but my first dry run with: # /etc/acpi/video_brightnessdown.sh or # /etc/acpi/video_brightnessup.sh had no effect. Btw: changing the brightness with something like: % echo 'brightness: 1' > /proc/acpi/toshiba/lcd works but "Power Management Brightness Applet" does not get notified by that change. In contrast changing the brightness with the applet is very coarse. Instead of 8 brightness-levels it is only able to set three levels (0, 3 and 7). Nevertheless the main goal is to get the function keys running.
