I just installed the nitrokey-app on Trisquel, which is an Ubuntu based distro. But whenever try to start the nitrokey-app from my terminal, i see the following message: Application started successfully. And then nothing happens.
I installed the nitrokey-app from the repository, following these instructions: Ubuntu | Nitrokey
Application icon should show up in tray bar. What window manager do you use? Latest GNOME (which may be bundled with your distribution) removes the tray bar altogether.
Another cause might be lack of communication with window manager due to running from console.
Could you start the application from within graphical menu?
Do you know which version of GNOME do you use?
To confirm whether App is running or not you may use pgrep:
$ pgrep -a nitrokey-app
7681 nitrokey-app
If there are no results then the App is not running.
Edit: we already have an open issue regarding GNOME and tray issues: #274. Please follow the updates there, if the app would appear to be running but without the tray.
besides installing the extension you have to enable it as well. Please start gnome-tweak-tool and enable it there. After that you may have to logout and login. This should work on every pure Gnome 3.26.
Well, it should work on every desktop environment which have a system tray Only the newest Gnome version (3.26) is known to have this issue. This is a design decision by the Gnome Project. All conservative DE should work though.
