Ubuntu 20.04.1 / Caffeine Indicator does not appear in status bar

Question

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

Answer 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)

Answer 2

press Super and type extensions, then find caffeine there and go to its setting and enable show on top panel
