I had the same problem on Ubuntu 22.10, but managed to solve it. I don't know which of the following actions worked, so I list them all:
I copied the blender.desktop
file that is in the Blender tar archive into the ~/.local/share/applications
folder, changed the path for the executable and for the icon, and I set it as executable. This didn't launch Blender and in the right click menu there was no Allow launching option.
I added the line:
application/x-blender=blender.desktop
to the /usr/share/applications/defaults.list
file.
Using a terminal:
echo "application/x-blender=blender.desktop" | sudo tee -a /usr/share/applications/defaults.list
This did not work.
I copied the blender.desktop
file to the desktop: here with the right click there was an Allow launching option, and it launched Blender. It was possible to add Blender to the Favourites and then I moved the blender.desktop
file back to ~/.local/share/applications
.
After the above, even after eliminating everything I had done, Blender remained in the favorites and is present in the Applications overview. I don't know, maybe I missed some logout or restart.
Note that since the first versions of Ubuntu, I had never installed Blender this way. I was always creating a Programs
folder, unpacking the Blender tar/zip, renaming the folder as blender
and creating the launcher. With this method I could always update the Blender version by simply unzipping the new zip and renaming the new folder.
With Ubuntu 22.10 it was just a bit more complicated, but it was also late at night.
Hope this can help.
