Crystal, thanks for the suggestion, but that didn't work either. However, I found a simpler way of doing it: Add the line
${exec_prefix}/bin/xrandr --size 1600x900 with whatever screen resolution you desire, to the file /etc/X11/xenodm/Xsetup_0 and restart xenodm. (Get acceptable resolutions using xrandr or lxrandr.)
