First of all. Thanks for Antergos, it is superb! No other distro has been this fast (tried Manjaro Openbox and it had lots of problems ) and because of the openbox I can modify it to look just the way I like! I have a few minor thinks that bug me but the big picture looks really good.
Anyway, this is not a minor thing. I have an ASUS n56dp laptop that has Radeon dual graphics with Radeon HD 7640G and Radeon HD 7730M. I just recently installed Antergos with Openbox. The problem is I can’t adjust the screen brightness in any way. With Mint installed I could adjust the brightness.
In /sys/class/backlight/ I have only radeon_bl0 folder, I can change the brightness value with echo “250 > /sys/class/backlight/acpi_video0/brightness”, but that won’t change the brightness of the screen. Trying to use xbacklight gives “No outputs have backlight property”.
I don’t know what to do next. Maybe installing the catalyst drivers could help? But I would not like to do that.
