Linux Mint 17 on Laptop Acer Aspire-E5-571G PART3

Automatic brightness control very very annoying, it dims down almost random, so you have to set it couple times...


To disable improper automatic brightness control, uncheck this:

To control brightness manually from 0% to 100% , install xbacklight

$ sudo apt-get install xbacklight

Don't know how to overwrite functional keys for brightness, so I made two new shortcuts for brightness control, with commands:

$ xbacklight -inc 5
$ xbacklight -dec 5

For non 60 fps videos, mplayer works pretty well with this config:

$ cat ~/.mplayer/config
# Write your default config options here!
