SWAY desktop
OK Have Sway running just fine and am using it as my daily driver. What I'm missing is some way to prevent the display from sleeping when playing full-screen content. I adjusted the time-out in the sway config; however, that's not the way to prevent the display from sleeping with full-screen active. Any ideas? With Gnome, one uses caffeine, but extensions don't work with Sway. Thanks!
Are you using swayidle? It's supposed to automatically keep the screen on when there is full-screen video playing. It's the same in Gnome: you generally don't need caffeine if a full-screen video is going.
How are you playing videos? Maybe the player doesn't correctly implement the idle inhibit protocol. Or if you're using sway bindings to make the window fullscreen instead of using the app's own fullscreen mode then maybe the player doesn't know it's fullscreen, and doesn't set up the idle inhibit.
If you do want manual idle inhibit control, if you use Waybar it has an idle inhibitor module that mimics caffeine. If you don't use Waybar there is a little Python script you can run. Kill it when you want to stop inhibiting idle. actually wib looks like a better option
The 2 line stanza works from a14o. However, the site you linked has lots of useful information that I'll use to set up my waybar icons!
