Undying unconfigurable process

[xeruf]

I am observing some odd behavior the last weeks:

• way-displays is running
• sending a command to way-displays does not work, it says it is not running
• trying to make changes through a plain swaymsg command (swaymsg output \* scale 2) get reverted immediately by way-displays
• killing the running instance immediately pops up a new one (this one is now clear since it is a systemd service)

❯ way-displays -s SCALE '' 2
ERROR: way-displays not running, check $XDG_VTNR
❯ ps aux | grep way-displays

sending a command to way-displays does not work, it says it is not running

The client determines whether the server is running by looking for a pid at /tmp/way-displays.${XDG_VTNR}.pid. What do you see in your /tmp?

It then finds the socket to use by looking at ${XDG_RUNTIME_DIR}/way-displays.${XDG_VTNR}.sock. What's in your ${XDG_RUNTIME_DIR}?

I suspect that the XDG_VTNR is different for the service. Are you using a login manager that sets 2?

trying to make changes through a plain swaymsg command (swaymsg output * scale 2) get reverted immediately by way-displays

Working as intended. way-displays will react to changes and apply its configuration. Canonical case: display arrives, sway sets it to default resolution.

this one is now clear since it is a systemd service

That's pretty cool. Can you please share your setup as a recipe?

It's not by me but the fellow great manjaro-sway maintainer, see https://github.com/manjaro-sway/desktop-settings/blob/sway/community/sway/etc/systemd/user/way-displays.service :)

Seems to work fine again, I think I accidentally had two processes running as mentioned in #161
