I'm on Ubuntu 14.04, and installed a .deb file I downloaded (so install happens through Software Center). (Almost) All went well, and the program icon appeared in the Dash.
When clicking it, nothing happens however. I can launch the program by typing its name in the commandline. I can also lock the program icon to the launcher once it runs, and launch it from there. That is however not what I want; I'd like to keep the launcher minimal.
This happens both with the Vivaldi browser and the Git Kraken tool. (So I guess it's not the program causing this.) Restarting does not solve the problem. Any hints appreciated.
