Needs to be reported to the Desktop Environment (e.g. XFCE) developers?

Per a discussion with XFCE developers in https://gitlab.xfce.org/xfce/xfce4-power-manager/-/issues/260, xfce-power-manager (Version 4.20) no longer controls any applications that use the screensaver/screen lock.

light-locker is one of those screensaver/screen lock applications that is installed automatically in Kali. Killing this process and disabling it at startup seems to be the only way to stop the automatic lock-out at 10 minutes.

With xfce-power-manager version 4.20 no longer controlling applications like light-locker, should this be removed from automatic install?

I've attempted to use xfce-screensaver instead, but it appears it has issues with PAM as I'm not able to login after the screen locks (separate issue, I know).

Just noticed this there:

Per Kali Bug Tracker, https://bugs.kali.org/view.php?id=9060, they suggested contacting the Desktop Environment developer.

As you can see i'm having "Reporter" permissions like you and obviously not part of the Kali team ;-)

That may be a tad confusing with a name like"kali-bugreport", no?

Names are irrelevant, eg. the existing user "kali-rick" is unlikely a kali member. Only the the status matters, "Developer", "Manager" or "Administrator" are Kali team members :-)

Above text of me is also ending with "(e.g. XFCE) developers?" so a question not a suggestion :-)

Relevant to this?

Links are more symptoms of the underlying cause. Consumers of the xfce4-power-manager packages (such as Kali) need to update their code, as XFCE Devs have removed the link to control the power saver feature. Anyone using xfce4-power-manager will have this issue, e.g. Kali, Debian, etc. In terms of Kali, xfce4-power-manager controlled this, but when XFCE removed this component, it no longer works in Kali.

IIUC Debian (would arrive in Kali afterwards) would only need to make sure that if xfce4-power-managrr is installed the light-locker is getting deinstalled and xfce4-screensaver is installed as https://xfce.org/about/tour mentions:

Lock screen management was massively simplified and "Light Locker" was dropped. "lock-on-sleep" is now synchronized with xfce4-session and xfce4-screensaver.

Screen locking settings are now only handled by xfce4-screensaver to avoid conflicts. A button to open xfce4-screensaver-preferences was added.

Then xfce4-screensaver should be the standard automatic install from Kali packages, and not "Light Locker", right?

Also, xfce4-screensaver has it's own login screen after locking (not lightdm), which for some reason has issues authenticating:

Then xfce4-screensaver should be the standard automatic install from Kali packages, and not "Light Locker", right?

IIUC yes, but from Debian packages which Kali is then inheriting from (Don't think that Kali is maintaining this package on their own).

which for some reason has issues authenticating

Another issue for the XFCE or Debian bug tracker?
