Doesn't detect Hydrapaper (flatpak)

[Lucki]

Does exec org.gabmus.hydrapaper in a terminal starts HydraPaper?

[DarkGhostHunter]

Nope, it doesn't, but flatpak run org.gambus.hydrapaper does. By the way, GNOME 46, not 40-

We're using GLib.find_program_in path() for which the application needs to be available in your $PATH. This should happen automatically though. Does /etc/profile.d/flatpak-bindir.sh exists?

If not, you can add the path manually by creating a file in your environment config directory:
$HOME/.config/environment.d/02-Flatpak.conf with the following content:

PATH=$PATH:$XDG_DATA_HOME/flatpak/exports/bin

If your $XDG_DATA_HOME is not set, replace that variable with $HOME/.local/share:

PATH=$PATH:$HOME/.local/share/flatpak/exports/bin

Re-login afterward.

Does /etc/profile.d/flatpak-bindir.sh exists?

nope.

... $HOME/.config/environment.d/02-Flatpak.conf

Nope either, the ../flatpak/exports/bin doesn't exist.

What does exists is /var/lib/flatpak/exports/bin.

Well then your Flatpaks are installed system-wide, just use that path then.
