Solution 1437470.1 : How to display video on a T5220

Applies to:

Sun SPARC Enterprise T5220 Server - Version All Versions and later
Information in this document applies to any platform.

Goal

This document describes how to display video on the framebuffer of the T-series machines where the console is set to virtual-console:

% more eeprom.out
output-device=virtual-console
input-device=virtual-console

Solution

One has to decide if they want the console device to the the video or the ILOM.
In either case there must be a /dev/fb device.

If it does not exist this is done by creating /dev/fb as a link the the device that is linked to /dev/fbs/<>fb0.

If one wants the ILOM, then change the Xserver to start up on a device that is not the console.

# cp /usr/dt/config/Xservers /etc/dt/config/Xservers

One may have to create the directory /etc/dt/config and edit the only non-blank and uncommented line to: (the word "console" is changed to "none")

:0 Local local_uid@none root /usr/X11/bin/Xserver :0 -nobanner

Reboot the system and the CDE login should show up on the console if there is a keyboard and mouse attached to the system.

If one wants the video to be the console they still have to have a /dev/fb.
In the boot prom settings, change the following:

output-device=screen
input-device=keyboard

Reboot the machine and the console output should show up on the video.
