Hello,

My understanding is that, in Blender, you set up the external image editor as "/var/lib/flatpak/app/org.gimp.GIMP/current/active/export/share/applications/org.gimp.GIMP.desktop". Is that what you meant?

If that's the case, I think it's not the right way to do. The .desktop files are just a way for Linux desktop environments (such as Gnome) to have information about programs that can be launched (such as the program title, its icon, the path to the binary to actually launch when the user clicks on the icon, etc.).

Try to open this .desktop file with a text editor. You should see something like:

[Desktop Entry] Version=1.0
Type=Application
Name=GNU Image Manipulation Program
(...)
Exec=gimp-2.10 %U
TryExec=gimp-2.10
(...)

In my case, what the desktop file is saying is to execute the command "gimp-2.10 %U" whenever I click on the Gimp icon.

In order to know where is located that `gimp-2.10` binary file, you can use the `which` command:

$ which gimp-2.10 /usr/bin/gimp-2.10

(yes, I'm using the version from a PPA, not the Flatpak version, so my path is for sure different from the one you're going to find.)

Hope this helps

Hello,

I have Linux Mint version 18.3 Cinnamon (64) bit

I'm using Blender 2.79b (Cycles)

I downloaded Gimp as a flatpack (2.10)

This is the path where Gimp.desktop is located:

/var/lib/flatpak/app/org.gimp.GIMP/current/active/export/share/applications/org.gimp.GIMP.desktop

However, when I use the function Edit Images Externally in Blender I get

the following error message:

Image editor could not be launched, please ensure that the path in User

Preferences > File is valid, and Blender has rights to launch it

Please note:

1. I've already saved the image to edit externally. 2. I verified the path where Gimp is located. 3. I accessed Gimp as root and changed all access values to: READ &
WRITE. The execute box is also checked.
4. I also saved the User Preferences in Blender.
I need this option for UV mapping which is very important in Blender. I
just need to give Blender

the right path and permission to launch the application.
Can anyone help?

Thanks

Also, just in case it matters, the flatpak Gimp has its own /tmp (in other words it doesn't see files in the system /tmp), so if Blender tries to start it on an image it put in the regular /tmp, it will fail.
