@ShayBox Could you have a look at this?

botiapa commented 3 years ago

In the meantime, @benpm could you post the output of xrandr --listactivemonitors

ShayBox commented 3 years ago

benpm commented 3 years ago

Here ya go @botiapa @ShayBox 

➜  ~ xrandr --listactivemonitors
Monitors: 2
 0: +*DP-2.8 1920/527x1080/296+1920+0  DP-2.8

Try the latest commit, I've never seen monitor names with periods

That seems to have fixed it, thanks!
