Solaris Handbook for Sun Frame Buffers

Multiple Monitor Configuration

Sun Ultra Systems

To run more than one frame buffer, you need to modify your /etc/dt/config/Xservers file. Identify the device name for the frame buffers you are using. To do this:

  1. Become superuser and open the /etc/dt/config/Xservers file.


    # cd /etc/dt/config
    # vi Xservers

  2. Modify the file by adding the device locations for the applicable frame buffers being used.

The following example shows the Xservers configuration file modified for one Creator (ffb0) card and two Expert3D cards (ifb0 and ifb1):


:0 Local local_uid@console root /usr/openwin/bin/Xsun :0 -dev /dev/fbs/ffb0 

-dev /dev/fbs/ifb1 -dev /dev/fbs/ifb0 -nobanner

Sun SPARCstation SBus Systems

When the system is booted, it looks for the sbus-probe-list, which determines the order in which the SBus devices are addressed. For the SPARCstation 10, SBus address f is reserved for the CPU and should always be the first address in the sbus-probe-list.

To determine the system information and sbus-probe-list, type:


% eeprom
     .
     .
     .
sbus-probe-list=0123
     .
     .

The addressing numbers are 0, 1, 2, and 3. However, 0 is reserved for the CPU and should always be the first address in the sbus-probe-list for all SPARCstation systems except the SPARCstation 10 system.

The following system information and sbus-probe-list (starting with f) will be displayed if you have a SPARCstation 10 system:


% eeprom
     .
     .
     .
sbus-probe-list=f0123
     .
     .
