I've removed the default GNOME keybinding to the Super key and I tried to rebind it using gsettings to its own key:
matt@hydrogen:~$ gsettings get org.gnome.settings-daemon.plugins.media-keys custom-keybindings ['/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/'] matt@hydrogen:~$ gsettings get org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/ binding '<Super>'
Setting it with gsettings works fine, but it doesn't work.
In the GNOME Settings GUI it shows up as "Disabled":
I've considered using xbindkeys, but this unfortunately doesn't support Wayland, which I am currently using. Obviously it seems like GNOME doesn't like me doing this, but are there any possible workarounds?
