xbacklight, hoping that it would be able to control my brightness. When trying to change brightness, I was told "No outputs have backlight property". After looking around, I found that this has to do with my computer not having a
/sys/class/backlight folder. I know that this is the problem but don't know exactly how to fix it.
Not sure if its needed or not but here some system info from inxi:
System: Kernel: 3.16.0-57-generic x86_64 (64 bit, gcc: 4.8.2) Desktop: LXDE (Openbox 3.5.2) Distro: Ubuntu 14.04 trusty Machine: HP EliteBook 8460p CPU: Dual core Intel Core i5-2520M CPU Graphics: Advanced Micro Devices [AMD/ATI] Seymour [Radeon HD 6400M/7400M Series]
Does this have to do with drivers (perhaps Intel/AMD graphics drivers)?
