hyprgrass: Unable to get gestures to work

Hi, I’ve been trying to configure my Surface Pro 4 to work with Hyprland. Saw this plugin and thought it might be handy for navigation, especially if I detach the keyboard. However, I can’t seem to get the plugin to respond at all.

I’ve tried installing via Hyprload as well as compiling manually and loading in my hyprland config with hyprctl plugin load /path/to/libhyprgrass.so. Interestingly, Hyprgrass doesn’t show up in the plugin list with hyprload plugin list if I’ve loaded it through Hyprload, which is what prompted me to try installing it manually, but does when manually executing the one compiled from source, though I don’t know if this is a quirk of Hyprload itself.

I don’t know if it’s anything to do with the way I configured it, although I’m fairly certain I’ve followed the readme to a T - my config is as follows:

gestures {
    workspace_swipe = true
    workspace_swipe_cancel_ratio = 0.15
}
plugin {
  touch_gestures {
  sensitivity = 4.0
  workspace_swipe_fingers = 3
  }
}

Current gesture bindings are:

bind = , edge:r:l, exec, notify-send "Hello there!"
bind = , swipe:1:d, exec, notify-send "Hello there!"
bind = , swipe:4:d, killactive

(I set it to execute notify-send as a way of testing, though I also tried the top 2 with just the standard workspace +1 command, but that doesn’t appear to have any effect either…)

Am I missing something?

I apologise in advance if I’ve made any rookie mistakes here. Still trying to wrap my head around Hyprland and everything associated with it!
