Thanks for the work!  I think John (Cc-ed) is going to update dependencies for
Hyprland in next mesa-updates, so the libdrm patch will likely be picked by
them.

In terms of ‘hyprland’ and ‘xdg-desktop-portal-hyprland’, these two packages in
my channel are made ready for upstreaming to Guix (but not their dependencies).

hyprland:

xdg-desktop-portal-hyprland:

libinput 1.24.0 is currently available in core-updates:

I didn't take a closer look at cairo update, but yes, this may require some
work, at least to be able to finish its tests.

hwdata with a pkg-config file is in core-updates too:

The main issue with hyprpm (plugin manager distributed with Hyprland, depends on
tomlplusplus, I removed it in my definition) is that it shells out to download
and build Hyprland and its plugins, making it work out of the box needs some
effort, and shipping yet another package manager is not what we want.

Hyprland plugins are not hard to package, we just need a loading mechanism.
Adding a search path may be a solution, but this requires some work and is
better done in upstream.

At least for me to accept hyprpm, it should work either out of the box (without
requiring users to install any extra package), or keep only the plugin loading
functionality.


Thanks
