[Pxc] Problem

[Rob Deuel]

Back again.  Thanks to Chanop Silpa-Anan for various suggestions.
Here is what happened.  [This is in a terminal window on GNOME desktop.]
May be more than you want to know, but figured to show what I have tried.

Check environment for DISPLAY variable:
	DISPLAY=:0
Check display permission:
	xhost gives "access control enabled, only authorized clients can connect".
Change with:
	xhost + gives "access control disabled, clients can connect from any host".
Do pxc_load:
	get "Loading pxc200 device driver (./pxc.o).......done".
Do pxc_xgrab:
	get "./pxc_xgrab: couldn't open "/dev/pxc0pgm": invalid argument".
Do pxc_status:
	get "./pxc_status: /dev/pxc0ctl: Invalid argument".
Do pxc_live:
	get "./pxc_live: using /dev/pxc0pgm
	Error in startup script: couldn't open "/dev/pxc0pgm": invalid argument'
	while executing "open $devicefile r" (file "./pxc_live" line 58)

What else?
Thanks.
