How to Determine which GUI is in Use

1.

Check the environment variable XLOGIN defined in the file /etc/rc.config.
Example (showing the CDE GUI being used):

# /usr/sbin/rcmgr get XLOGIN
cde
#

1. If the variable is defined to be "cde," then the default GUI is CDE. If the

variable is defined to be "xdm," then the default GUI is XDM/Motif.

How to Change the Resolution and Refresh Rate on XDM GUI

1. Log in to the system as "root".

2.

Make a backup copy of the file /usr/lib/X11/xdm/Xservers .
Example:

# cp /usr/lib/X11/xdm/Xservers /usr/lib/X11/xdm/Xservers.original

3. Edit the file

/usr/lib/X11/xdm/Xservers

and add the appropriate X

server Option, "-screen0" and or "-vsync0" to the line that starts the X
server. This line is generally the last line in the file Xservers.
Example line from the Xservers file used with XDM/Motif.

:0 local /usr/bin/X11/X

Or

:0 local /usr/bin/X11/X -nice -2

X server Options:

-screen[screen] WxH
Set screen (W)width and (H)height.
-vsync[screen] Hz
Set screen (Hz) Vertical refresh rate
