Fixing Remarkable's 'Screen Share' Screen in Yabai

1-minute read

Pretty niche post. If you are running yabai and using the Screen Share feature from remarkable, yabai won’t manage the window. It looks like it doesn’t manage Dialogs by default, which that screen is (see the "subrole": "AXDialog" part):

1

❮ sleep 3 && yabai -m query --windows --window

As per the docs above:

Even if a window is eligible for management, only standard windows (subset of a real window – e.g not dialogs) can be tiled unless a rule specifies the AXRole and AXSubrole filter with the manage=on property.

So we just need to add a rule to manage it automatically.

Add to your .yabairc:

1

yabai -m rule --add app="reMarkable" role="AXWindow" subrole="AXDialog" manage=on

And refresh by executing the config file (weird when you say it out loud huh?).
