I don't use any X resource settings, just the following startup file:

;---cut here---
;- Set up 8 bit display and allocate colors

device, retain=2, decomposed=0, pseudo=8
window, /free, /pixmap, colors = -5
wdelete, !d.window

;- Set graphics and widget font sizes

device, set_character_size=[6,9]
widget_control, default_font='7x13'

;- Ensure IDL 5 XMANAGER behavior is consistent with IDL 4

xmanager, catch=0
;---cut here---

This gives me consistent results on all Unix platforms. Set the
environment variable IDL_STARTUP to the full path and name of the
startup file. Note that if True Color mode is desired, replace
'pseudo=8' with 'true=24' in the the DEVICE keywords.

Cheers,
Liam.
