It is also unresponsive to mouse input for me. Perhaps mouse/trackpad/touch support was not added anyways, since you would need to rewrite a few things since you wouldn't be able to fall back on xinput.

For mouse input you can do this (adapt to your theme/config):

rofi -me-select-entry 'MousePrimary' -me-accept-entry '!MousePrimary' -theme ~/.config/rofi/appmenu.rasi -show drun -show-icons

For me this works better than the default with a mouse, i.e. click selects and release accepts. This works the same with trackpad for me (under Hyprland).

However, I came here because touch screen also isn't working. I checked with wev and saw that I get wl_touch: down and wl_touch: up events, which is of course distinctly different from a mouse button event (touchpad with tap generates the same event as MousePrimary click). So I guess we need to be able to configure the correct event for touch screen (i.e. wl_touch) as a keysym in the config. The big question is how?

(Ideally something semantically clear as rofi -me-select-entry 'TouchDown' -me-accept-entry 'TouchUp' ?)

EDIT: I took a quick look at the source, and noticed that input events are handled by libnkutils, which doesn't appear to have specific "modern" libinput support, i.e. things seem to be handled at the level of key-presses and pointer/button events. That could mean that to make touch screen work, one would additionally need something like https://github.com/libts/tslib and/or modify/overhaul the input handling in some other way?
