Fullscreen one out of two monitors

[matthew-piziak]

When I am running Chromium in EXWM I can fullscreen YouTube across two monitors using YouTube's fullscreen button or F, and I can fullscreen Chromium itself across two monitors with Emacs's C-c C-f which runs exwm-layout-set-fullscreen.

Naturally there isn't much point in watching a YouTube video on one half each of two monitors. How can I tell EXWM to fullscreen something across one monitor only?

Note that the problem exists in tiling mode as well as floating mode.

Here is the same question as a StackExchange post:

What's the output of xrandr? Basically when an app is set to full screen EXWM would resize it into the size of its workspace. So it depends on how workspaces are placed.

Got it. I think I have a single workspace, that would explain it. Thank you!
