@jacekpoz nice work on the change, but I have just been able to confirm that https://github.com/hyprwm/Hyprland/pull/3544 is now in working condition! Maybe you can give that commit a try (along with the config to make it work)? If it works for you too it may be best to close this PR.

I haven't tried that yet, I think it's a good idea to have this temporarily before that PR is merged - unless it's gonna get merged soon

tested f52580717e65d86dafd9cf458e15919950e0625a, didn't work with no config changes and upstream rot8

not sure if any config changes are needed, will try again today in the evening / tomorrow and read through all the comments and code

if there's any config needed please let me know, I'll retest

I had to explicitly map touch inputs to my output name, like this:

input {
    touchdevice {
        output = eDP-1
    }
    tablet {
        output = eDP-1
    }
}

sorry for the long response, that config does in fact work

closing, supported natively in hyprland now
