Ubuntu 19.10 - cannot run .desktop files
I believe all you have to do is right click on the .desktop
file on the Desktop, and click Allow Launching
.
which will show the application's icon and make it launchable.
For now I have switched back to 18.04. Hopefully by the next LTS release this is something that will have been worked out.
Allow Launching
option doesn't show if file already has execution permission set before you upgraded to new version. To resolve:
chmod 644 file_name.desktop
then right click on the file in the desktop, you will see allow launching.
