Bug Description
In 14.04 using kernel 3.13 the special function buttons of this HP Compaq nx6310 laptop used to work correctly. I could increase or decrease brightness, invoke the battery settings (mostly useless but it worked), switch to an external display or enter sleep mode. The key functions are invoked using Fn + the key with the designated function as listed below.
Fn + F3 - Sleep - button/sleep SBTN 00000080 00000000 K
Fn + F4 - Switch to external display - video/switchmode VMOD 00000080 00000000
Fn + F8 - Battery information - button/battery BAT 00000080 00000000 K
Fn + F9 - Brightness down - video/brightnes
Fn + F10 - Brightness up - video/brightnessup BRTUP 00000086 00000000
I went through the troubleshooting steps described at https:/
Using xbacklight I can still change the brightness in 14.10, if that information is of any help.
