Request to allow xfce4-screensaver at least as an alternative to
light-locker.

In the meantime, XFCE has removed configuration support for light-locker. This means that an installation of trixie with
XFCE-Desktop installs light-locker, but this package is no longer configurable via the graphical UI of XFCE. The desktop
is locked after 5 minutes of inactivity without the possibility to change this behavior in the XFCE configuration UI.
This is very annoying.

Instead, the xfce4-screensaver package is now supported in the XFCE configuration UI. The package task-xfce-desktop
should therefore no longer recommend light-locker, but xfce4-screensaver instead so that xfce4-screensaver is installed
together with the XFCE desktop.

If possible, this change should be made before the release of trixie.

Users installing Trixie XFCE are running into exactly the issue Ulrich
Gaiser describes.

In addition, there is an 11 year old bug in light-locker:

Users are running into this bug after installing Trixie XFCE

xfce4-screensaver does not have this bug: another good reason to remove
the light-locker recommend.

Hello,
I did an install of xfce with the daily netinst image to test this change to tasksel. I ended up with both light-locker and xfce4-screensaver installed. I think this may be because the control file for xfce4-session lists light-locker first in the screensavers it recommends but I am not sure.

tasksel does no longer pull light-locker in by its package dependencies for xfce, so there must be some other Depend/Recommend, most likely from an xfce metapackage.

Does Power Manager function as intended in 4.20?

xfce4-session recommends light-locker, but also xfce4-screensaver:

rec: light-locker
    simple screen locker for lightDM display manager
or xfce4-screensaver
    screen saver and locker that is integrated with the xfce4 desktop
or xscreensaver
    Screensaver daemon and frontend for X11
or mate-screensaver
    MATE screen saver and locker

Would it cause light-locker to be installed if task-xfce-desktop is no
longer pulling light-locker?

I already identified xfce4-session being the reason possibly, and just tested
this on freshly installed sid with a console-only installation (without any
desktop):
installing xfce4-session there pulls in light-locker.
So this issue needs to be fixed in xfce4-session now.
Reassigning.

Thanks.

Would it be possible to bump up the severity level because this bug
means that Power Manager is basically broken in a fresh install of
Debian Trixie XFCE.

XFCE 4.20 dropped light-locker, so power manager has no control over
screen blanking, and suspend fails after screen lock with default
settings due to a long standing bug in light-locker.
