Bug#1092854: xfce4-power-manager: Power Manager screen 'lock screen is NOT set' in window 'System', but screen locks after set time.
This is really an issue with task-xfce-desktop, which recommends
light-locker.
XFCE 4.20 dropped light-locker in favour of xfce4-screensaver (which
was added to Trixie).
Users installing Trixie XFCE are running into this issue, and the
solution seems to be to uninstall light-locker and install
xfce4-screensaver.
