I have Plasma 5.25.5 installed on Arch. My problem is Google Chrome does not inhibit screensaver when watching videos/streams.

From Chromium sources it seems like 3 types of inhibitors are supported: https://chromium.googlesource.com/chrom ... r_linux.cc

• org.gnome.SessionManager
• org.freedesktop.PowerManagement
• org.freedesktop.ScreenSaver

From PowerDevil sources it seems like org.freedesktop.PowerManagement should be supported in Plasma: https://github.com/KDE/powerdevil/blob/ ... gement.cpp

However it's not showing up in busctl output. Is it disabled? Is there a configuration I need to change or a package I need to install?

I did verify that org.freedesktop.login1 connection is present and systemd-inhibit works correctly. But sadly Chrome cannot use that.
