Running OpenWindows on Multiple Monitors

1. To run multiple monitors with OpenWindows Version 3

1. Set up the OpenWindows Version 3 environment by typing the following command (use the actual pathname for /usr/local where OpenWindows Version 3 software is located):

   ---

   % setenv OPENWINHOME 
   [[/usr/local/openwin]]

   ---

2. Verify that a device file already exists for the desired frame buffer by typing:

   ---

   # ls -l /dev/fbs/cgsix1

   ---

   If the device file already exists, a message similar to the one shown below is displayed. If so, skip Steps 3, 4, and 5 and go to Step 6. If the "not found" message is displayed, continue to Step 3.

   ---

   crw-rw-rw- 1 root      67,   0 Jan 10 1991 /dev/fbs/cgsix1

   ---

3. Become superuser, halt the system, and perform a reconfiguration boot, as follows:

   ---

   # boot -r
   

   ---

   The system probes all of the attached hardware devices and creates the device file for the second frame buffer.

4. Verify the newly created file by typing:

   ---

   # ls -l /dev/fbs/cgsix1

   ---

   A message similar to the following is displayed, indicating that the device file was successfully created:

   ---

   crw-rw-rw- 1 root      67,   0 Jan 10 1991 /dev/fbs/cgsix1

   ---

5. Exit the superuser mode.

6. Specify the screens that you want to run by typing:

   ---

   % $OPENWINHOME/bin/openwin -dev /dev/fb -dev /dev/fbs/cgsix1

   ---

   ---

   Note -

   The order in which the devices are listed is important. The first device corresponds to the left screen; the second device corresponds to the right screen. The names of your devices (for example, /dev/fbs/cgsix1) may differ. Use the device file name that is appropriate for your system.
