Compaq VX1 manual Backing Store and Save Unders, Current Graphics Resolution

3.2.4Backing Store and Save Unders

By default, backing store and save unders are enabled. If the default visual depth is changed to 16 or 24, it is recommended that backing store and save unders be disabled.

To disable these features, add the options "-bs-su" to the argument list in the X server’s configuration file. Refer to the example in Section 3.2.3.

3.3Configuring Graphics Resolution or Vertical Refresh Rate for Tru64 UNIX

There are two X server related files that can be used to configure or change characteristics of the X server. Systems by default use a file named "Xservers" to start and optionally pass startup configuration parameters to the Xserver.

3.3.1Current Graphics Resolution

The graphics Resolution and Refresh Rate is set at the default value, 1024x768 at 70Hz Refresh Rate. The graphics resolution of a running system can be obtained by executing the command /usr/sbin/sizer -gr. The Refresh Rate may be obtained from the X servers file /var/dt/Xservers.

3.3.2Changing the Resolution & Refresh Rate Using the Xservers File

The steps necessary to change the X servers graphics resolution differ depending on which X Windowing System is in use, XDM/Motif or the newer standard CDE (Common Desktop Environment). UNIX systems running version 4.0F, and G can use either the XDM/Motif or CDE GUIs.

If your system is running version 4.0F, or G, you must determine which GUI is in use for the system and then proceed to the appropriate section of this document, "How to Change the Resolution and Refresh Rate on XDM GUI" or "How to Change the Resolution and Refresh Rate on CDE GUI".

Systems running UNIX versions 5.0 or higher can use only the CDE GUI, so you may skip directly to "How to Change the Resolution and Refresh Rate on CDE GUI".
