XnView Software

I have been using and enjoying XnView MP on Linux Mint for quite some time. I added the GIMP executable to the Configure Programs dialog quite some time ago and it works great. The Linux Mint repository is a bit behind on the GIMP version so I installed the latest Flatpak version of GIMP.

The problem I'm having is that I can't get it working in the Configure Programs dialog so I can use "Open With...".

The path being used by the Linux Mint start menu is '/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=gimp-2.10 --file-forwarding org.gimp.GIMP @@u %U @@' (without the single quotes).

I tried selecting the executable /usr/bin/flatpak and adding the rest to the Parameter field but that doesn't work. Any help would be appreciated.

This question is old, but it hasn’t been answered yet, so here is a workaround that works for me.

Create a bash script with the following command:
In XnView, configure a new "Open with" program that points to this script. The path to the script is sufficient. No additional arguments need to be provided.

I hope this helps.
