The man page for XF86Config says that it supports discrete values but it
generates an error. The commented out lines below break and the
uncommented versions work:
HorizSync 37.5 - 63.7
# HorizSync 37.5, 37.88, 37.90, 46.875, 48.08, 56.48, 60.023, 63.7
# VertRefresh 60, 60.317, 70, 70.069, 72.187, 72.81, 75, 86.906
I have attached the resulting output for using discrete values to bug 21631
(attachment 6112 [details]).
XF86Config is the config file for XFree86-Servers-3.3.6. You've filed this
bug against XFree86 (4.0.2), and are saying it is a bug with XFree86 4.
While this may be true, more likely you've just put the data in the wrong
config file. XFree86's config file is XF86Config-4.
Can you please clarify what version you're using, perhaps attach the config
file, and your XServer output logs?
I am not seeing this after upgrading to XFree86 4.0.2.
