4. Edit the file /etc/dt/config/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 CDE:
:0 Local local@console /usr/bin/X11/X :0 -screen0 1280x1024
X server Options:
Set screen (W)width and (H)height.
-screen[screen] WxH
Set screen (Hz) Vertical refresh rate
-vsync[screen] Hz
___________________________Note ____________________________
• These are device dependent X server options and not available for ALL graphics
options. See Table 3–1 for supported Resolutions and Refresh Rates.
• Both the Width and Height should be specified in the "-screen" option and not just
the Width. On some X server graphics devices setting ONLY the Width will cause
the X server to fail.
• The [screen] number need not be specified if only one screen exists or if the user
wants all screens to use the same values. The [screen] value is generally '0' as
shown in the example below.
Example:
-screen0 1280x1024
^
| [screen] value
• Anything added after the "-I" option will be ignored by the X server and passed on
to the DDX, Device Dependent X layer of the server. The "-screen" and or "-
vsync" option(s) should precede the "-I" option.

5. Restart the CDE GUI.
For DIGITAL UNIX V5.* systems use:
# /sbin/init.d/xlogin stop
# /sbin/init.d/xlogin start
Examples of Typical Resolution and Refresh Rate Settings Using CDE
