Just a followup:
First, thanks to both Colin W. and Brian K. for their ideas and scripts
-- they put me on the right track, and got things working for me
initially.
The real "duh" moment came to me this afternoon when I remembered that
the DISPLAY environmental variable is set to "hostname:0.0" -- I could
simply test for the hostname in the DISPLAY value from within my
.xsession file to determine what set of defaults to use.
So now in my .xsession, I test for the appropriate hostname and set a
few environmental variables, which are then accessed by other setup
files to set up my desktop on this smaller display.
Thanks for all the pointers!
