xclock -d (digital) does not work well with -geometry.
In Openbox (my windowmanager) I was able to get around this by adding to ~/.config/openbox/rc.xml
<application class="XClock">
<position>
<x>3515</x>
<y>1038</y>
<monitor>1</monitor> <!-- 0 is primary, 1 is secondary -->
</position>
<focus>no</focus>
<decor>no</decor>
<desktop>all</desktop>
<layer>below</layer>
</application>
With settings in rc.xml starting in .xinitrc doesn’t work. Start in ~/.config/openbox/autostart.
xclock -d -chime -update 1 &
