How to start Viber on system boot?
Go to startup applications -
Click on the Add button -
and fill out the fields in the following manner -
Name: Viber
Command: /opt/viber/Viber
Comment: Connect. Freely.
Alternatively, you can create a symbolic link between the .desktop file created by the method suggested by αғsнιη and /etc/xdg/autostart/ -
sudo ln -s /path/to/Viber.desktop /etc/xdg/autostart/
GUI method:
You can achieve what you want by going to the Startup Application Preferences from dash and create a NEW startup item. Just click on the Add button, which brings up an input dialog. In that dialog, you specify a name to call it, an optional comment blurb, and the command to execute(will be /opt/viber/Viber), which would be the path of Viber. When you're done, a new NAME.desktop file will appear in ~/.config/autostart.
CLI method:
or you can create that .desktop file by your hand. (Advanced users using this method)
Create a Viber.desktop file in ~/.config/autostart/ and copy&paste the the following content in it and save.
[Desktop Entry]
Type=Application
Exec=/opt/viber/Viber
Hidden=false
Name=Viber
X-GNOME-Autostart-enabled=true
You can create/edit Viber.desktop file by gedit ~/.config/autostart/Viber.desktop in Terminal.
Done. Logoff and login back to see the changes.
As documentation Desktop Entry Specification, the Startup Applications are .desktop files stored per-user in:
~/.config/autostart
And also globally, for all users, in:
/etc/xdg/autostart
(Note that in KDE it's stored in ~/.kde/Autostart directory.)
The enable/disable feature is provided by this attribute in each .desktop file:
X-GNOME-Autostart-enabled=true (or false)
If a user toggles enable/disable status of a given application (without deleting it) that was in the system folder, it is copied to the user directory and then the attribute X-GNOME-Autostart-enabled is changed. If a user deletes a given application from the list, the .desktop is copied to user folder with the Hidden=true attribute (or the file is simply deleted if it was present just in the user directory)
