Monitors default to "none"

Describe the bug Brightness Controller crashes

warning: output None not found; ignoring
xrandr: Need crtc to set gamma on.
Traceback (most recent call last):

The monitor/output shown appears to be correct. If I reselect the same monitor that is already shown, the program works as expected. It seems like this is just an issue with it defaulting to None.

To Reproduce Steps to reproduce the behavior:

1. Open Brightness Controller
2. Adjust brightness slider

Expected behavior Brightness slider adjustment doesn't cause crash.
