I have installed flatpak to install gimp on Ubuntu 16.04:

flatpak install https://flathub.org/repo/appstream/org.gimp.GIMP.flatpakref

After the installation was done I couldn't find any application on my system, it also did not appear on my Desktop. Where to look for it?

UPDATE: Searching for gimp did not give me the right result, anyway by searching for GNU Image Manipulation Program gave me the right result

In short: Reboot or log out and log in after installing the flatpak package to see flatpak apps in the launcher.

Explanation:

Flatpak collects all .desktop files of system-wide installed applications in /var/lib/flatpak/exports/share/applications and of per-user applications in ~/.local/share/flatpak/exports/share/applications.[1]

Application launchers search for apps in $XDG_DATA_HOME directory (default ~/.local/share) and $XDG_DATA_DIRS colon-separated list (default /usr/local/share/:/usr/share/).[2][3]

flatpak Ubuntu package installs /etc/profile.d/flatpak.sh script that adds the aforementioned flatpak export directories to XDG_DATA_DIRS on startup. And just running the script after install won't help, it has to be done before the desktop starts because it reads that environment variable only when starting.

To run Gimp:

flatpak run org.gimp.GIMP "$@"

But AFAIK there is a desktop file somewhere, I have a ~/.local/share/applications/org.gimp.GIMP.desktop with:

The real installation is in /var/lib/flatpak/app/org.gimp.GIMP/

If you are used to "native" Gimp, be aware of some restrictions:

  • the "recent files" are not shared with other apps in the system
  • the /tmp directory as seen by Gimp is remapped to a directory specific to flatpak, so you cannot share files through that (which is unfortunately required for some apps, such as web browsers)
  • the Python runtime is specific to Gimp
  • the Gimp profile is buried in ~/.var/app/org.gimp.GIMP/config/GIMP/2.10/
  • you may want to use Edit>Preferences>Folders to setup folders in more "visible" directories for your brushes, patterns, scripts and plugins
  • compatibility with the popular plugins (GMIC, resynthesize...) isn't clear. It seems this requires flatpak versions.

To make Flatpak applications available in CLI, you can use a simple script like:

#!/bin/bash

Put file in /usr/local/libexec/flatpak-runner and then


symlink for instance /usr/local/bin/spotify and /usr/local/bin/gimp


to ../libexec/flatpak-runner


declare -A pkgs


pkgs=(
 [spotify]=com.spotify.Client
 [gimp]=org.gimp.GIMP
)


cmd=basename $0
args=$@


flatpak run --command="$cmd" ${pkgs[$cmd]} $args
