My fix for this was to modify the X11R3 xdm to run the script Xsetup around
the time that the login widget was being displayed.  That is, in the
routine ManageSession, it loads the resource database and exec's
a shell to run 'Xsetup'.  After the greet widget exits, the login
resources are unloaded and all of the children of the exec'ed shell
are killed.  The normal session processing is done thereafter.

This not only allows setting of the root background when the greeting
widget is displayed, but it also allows the running of "safe" clients on the
login screen - a clock or mailbox status display.
