Ubuntu 22.04: QSystemTrayIcon needs reboot to display after Gnome Shell Extension App Indicators is installed

  Kiến thức lập trình

Using Qt Framework on Ubuntu 22.04. The UI consists of a QSystemTrayIcon which is dependent on the installation of the App Indicator Gnome Shell Extension:

$ sudo apt install gnome-shell-extension-appindicator

QSystemTrayIcon can be seen but it requires a logout/login after installing gnome-shell-extension-appindicator. Is there a way to have gnome-shell-extension-appindicator take effect enabling the QSystemTrayIcon to display without having to logout and login back in?
