Dear Maintainer,

ukui-screensaver-backend unconditionally creates an interface for
org.kde.kglobalaccel, including when running in the LightDM greeter
session.

Creating the QDBusInterface is enough to activate
org.kde.kglobalaccel, even before any global shortcut operation is
performed.

In the greeter session this starts plasma-kglobalaccel5.service. The
service cannot connect to the display and exits, after which systemd
restarts it repeatedly until the start limit is reached.

Typical log output includes:

systemd: Starting plasma-kglobalaccel5.service…
kglobalaccel5: qt.qpa.xcb: could not connect to display
systemd: plasma-kglobalaccel5.service: Main process exited
systemd: Scheduled restart job

This happens on every boot and may leave multiple core dumps behind.

Global shortcut blocking is not needed in the greeter session, since it
runs in its own LightDM display session.

Expected result:

When running in greeter mode, ukui-screensaver should not activate or
contact org.kde.kglobalaccel.

This is separate from the ukui-session-manager issue about the missing
display environment in the simpleDesk activation environment. That
issue affects services which legitimately need display access, while
this issue is that kglobalaccel should not be started by the greeter in
the first place.

Regards,

Changes:
 ukui-screensaver (4.20.0.5-1) unstable; urgency=medium
 .
   [ zhangpan ]
   * New upstream bugfix-only release.
   * Fix KglobalAccelHelper talking to org.kde.kglobalaccel in the
     lightdm greeter: constructing QDBusInterface already triggers
     service activation, and the systemd user instance in the greeter
     has no DISPLAY, so the KF5 kglobalaccel5 daemon aborted with
     SIGABRT five times on every boot.(Closes: #1148106)
   * Fix the lock/login screen staying in English when the user has
     no explicitly set language: fall back to the system language
     when the user language is empty or its translation file is
     missing, both at startup and on current-user
     changes.(Closes: #1148505)
   * Hide the lightdm-xsession, kylin-wlcom and ubuntu entries from
     the session switcher list on the login screen.
   * Drop the leftover no-op preinst maintainer script.
   * Install the LoadCustomPlugin example into /usr/share/doc.
   * Bump debhelper compatibility level to 14.
