Ok.

Went to try this, as I’ve never done it before. I’m on Pop_!OS Cosmic (Ubuntu 24.04 variant).

This command in a CLI opens GIMP: flatpak run org.gimp.GIMP

This is the Settings page:

In ART, I get this:

Any idea what am I doing that is wrong?

thanks

HI,
In my environment, GIMP: flatpak version and ART: official binary.

Did you install your ART through flatpak?

Yes.

I tried using following starting option with ART flatpak version to communicate with GIMP, however they are all failed.

--socket=system-bus
--socket=session-bus

It seems that it is impossible to start GIMP from ART flatpak version.

The following works for me, I’m using Fedora Silverblue 48, both ART and GIMP are flatpaks, in terminal do:

flatpak override --user --talk-name=org.freedesktop.Flatpak us.pixls.art.ART

Then for external editor input:

"flatpak-spawn --host flatpak run org.gimp.GIMP"

Thank you very much for your useful information.
In my environment (Kubuntu 24.04), I can start GIMP from ART flatpak version!
