SUMMARY
When changing brightness after installing powerdevil-ddcutil from AUR (because arch repo does not include it) I tried changing the brightness and noticed that it changes brightness for both monitors.

STEPS TO REPRODUCE
1. Install powerdevil with ddcutil support
2. Try changing brightness setting
3. Observe both monitors

OBSERVED RESULT
Brightness changes for both monitors.

EXPECTED RESULT
I would expect to have 1 slider for each monitor. Maybe moving this setting to display settings is the way?
