Brightness keys on Linux Mint for Acer E3-111

Enabling brightness control is moderately easy (I’m pretty sure they worked out of the box on slackware).

Go to codingtony/acer-brightness-linux-acpi and follow the instructions. Change /etc/acpi/events/acer-tm-brightness-down and /etc/acpi/events/acer-tm-brightness-up with the correct events:

event=video/brightnessdown BRTDN 00000087 00000000


event=video/brightnessup BRTUP 00000086 00000000

Restart acpid and the shortcuts should start working.
