Description Mohammad K. 2024-12-01 11:58:15 UTC 
SUMMARY

When I login into my system with two monitors connected (one built-in laptop and one external), I only see one brightness slider for the external monitor in applet. To solve it, I have to unplug and re-connect the external monitor to be able to change brightness of both screens.  

STEPS TO REPRODUCE
1. Connect an external monitor to laptop
2. Restart system and login
3. Open screen brightness applet

OBSERVED RESULT
You only see brightness slider for the external monitor

EXPECTED RESULT
I should have two brightness sliders.

Also, I guess users should be able to change the brightness from system settings!
