Thanks for all the answers I received. Now I know that to display an image in the background for
XDM, I should place this entry in the Xsetup_0 file:
xv -root -quit MYPIC
Now, the Xsession file controls the start process of a session for the system, and
.xsession files do the same if specified for any one user.
Next question then is, is there an equivalent to the .xsession file for Xsetup_0.
i.e. - what if I wanted to display one image for a default, but another for a specific user in the
background of XDM? Thanks
John
