I installed Xubuntu 24.04 from Xubuntu 22, but after installing caffeine (keeps desktop from locking) and trying to run the app it fails with following warning:

/usr/bin/caffeine:24: DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html
  import pkg_resources

I did skim over the details provided at the page referenced in the failed-to-run warning, but it appears the details are geared toward developers.

Caffeine ran fine in Xubuntu 22, so any ideas what I might be able to do to get it working in XXubuntuubu 24 ?

If you are running gnome, an alternative to caffeine (debian package) is caffeine (gnome extension). See the github link for screenshots:

It seems that the development of Caffeine has stopped for several years. A workaround is to use Stimulator.

You can install it from Flathub. Open a terminal and enter the commands one by one.

sudo apt install flatpak
flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
flatpak install flathub io.github.sigmasd.stimulator

I have a hot-key ( Whisker Menu > Keyboard > Application Shortcuts ) on my laptop bound to a script that toggles presentation mode ( Panel > Power Manager Plugin ):

Presentation Mode toggle

At some point after I upgraded to 24.04 I noticed it had stopped working. However, a few tweaks seem to have fixed it:

#!/bin/bash

notify(){
    # cf. https://github.com/vlevit/notify-send.sh/blob/v0.2/notify-send.sh
    notify-send.sh -R /tmp/presentation-mode "$1"
}


pmode(){
    xfconf-query -c xfce4-power-manager 

        -p /xfce4-power-manager/presentation-mode "$@"
}


case $(pmode) in
    true)
        pmode -s false
        xset s 600 600
        xset s blank
        xset s on
        xset dpms 120 300 600
        xset +dpms
        notify "Presentation mode disabled"
        ;;
    false|*)
        pmode -s true
        xset s 0 0
        xset s noblank
        xset s reset
        xset s off
        xset dpms 0 0 0
        xset dpms force on
        xset -dpms
        notify "Presentation mode enabled"
        ;;
esac

Some of the xset commands may be unnecessary.
