Forcing KDM mouse pointer (cursor) size

[Ian Pilcher]

One of my displays is a large 2K screen.  It's presence causes Qt (both
4 and 5) to default to an oversized mouse pointer, which looks rather
ridiculous.

This is easily fixed in my Plasma session though the Cursor Theme in
system settings.

Does anyone know how to make an equivalent configuration change for KDM?

I'm not aware of any way to configure that for kdm (sddm can via 
CursorTheme=... key)

And as soon as sddm grows XDMCP support I'll be all over it.  :(

This turns out to be almost as simple as it is undocumented.  All that's
necessary to run kdm with XCURSOR_SIZE set to the desired value (24 in
my case).  The theme can be set with XCURSOR_THEME, if desired.

So I've used 'systemctl edit kdm' to create an override file
(/etc/systemd/system/kdm.service.d/override.conf):

[Service]
   Environment="FREETYPE_PROPERTIES=truetype:interpreter-version=35"
   Environment="XCURSOR_THEME=breeze_cursors"
   Environment="XCURSOR_SIZE=24"
