Ubuntu 20.04.1 / Caffeine Indicator does not appear in status bar

  • 772

I recently updated from Ubuntu 18.04.4 to 20.04.1. Although Caffeine Indicator is listed in the Startup Applications ...

Screenshot of Startup Applications

... it does not automatically appear in the top status bar after I log-in. This worked in the former Ubuntu version.
Is there something I can do about it?

Environment

  • Caffeine Indicator version: 2.9.4
  • Window manager: Gnome 3.36.3
  • Desktop environment: ubuntu-wayland
  • Linux distribution: Ubuntu 20.04.1

Analysis

Starting the application from the shell produces the following output:

$ caffeine-indicator 
/usr/bin/caffeine-indicator:184: PyGIDeprecationWarning: Since version 3.11,
    calling threads_init is no longer needed. 
    See: https://wiki.gnome.org/PyGObject/Threading
  GObject.threads_init()
/usr/bin/caffeine-indicator:106: DeprecationWarning: 
    AyatanaAppIndicator3.Indicator.set_icon is deprecated
  self.AppInd.set_icon(icon_name)

When I activate it then this is output:

INFO:root:caffeine-indicator is inhibiting desktop idleness

  1. The caffeine package includes three commands: caffeine,caffeinate and caffeine-indicator.

    The caffeine is what is responsible for preventing idle, but it only runs in the background. You need to run the caffeine-indicator to control it form topbar.

    Having both of those in the startup apps (one entry for /usr/bin/caffeine and one for /usr/bin/caffeine-indicator) works for me.

    I'm on 20.04 and I've installed caffeine 2.9.4-2 using sudo apt install caffeine (the same as apt-get, btw)
