Sun's Sbus framebuffers are able to detect what frequencies and
resolutions the monitor is able to run at. This is done through
the use of several pins on the card connector.

The most likely reason why a non-Sun monitor is not working
with one of our framebuffers is because the monitor is not
correctly reporting the resolutions it can handle, so the
framebuffer is using a default scan rate/resolution which
the monitor cannot handle.



Resolution: Top

A video cable needs to be fashioned up to report the resolution(s)
the monitor supports. The SRDB article entitled "Sun Class B Monitor
Connector (13W3) Pinout information" will be of some use here.

The pinout specifies that pins 3, 4, 8 & 9 return the information
about the resolutions the monitor supports. The pins need to be
connected following the guidelines in the table below.

As an example, to tell the framebuffer that the monitor supports
a resolution of 1280x1024 at 76 Hertz, pins 3 & 9 should be
connected to pin 4, and pin 8 should be left unconnected.


Sense Pin (Resolution) Allocation

Code Scan Rate Pin 3 Pin 8 Pin 9
Sense 2 Sense 1 Sense 0
-------------------------------------------------------------------
7 No Monitor N/C N/C N/C

6 1152x900 76Hz N/C N/C Sreturn

5 Reserved N/C Sreturn N/C

4 1152x900 76Hz N/C Sreturn Sreturn

3 1152x900 66Hz Sreturn N/C N/C

2 1280x1024 76Hz Sreturn N/C Sreturn

1 1600x1280 76Hz Sreturn Sreturn N/C

0 Reserved Sreturn Sreturn Sreturn
-------------------------------------------------------------------
Sreturn = Logic ground, Pin 4
N/C = Not Connected

Also take a look at this thread which may be helpful (if you get a dumb terminal, you might be able to change to whatever your monitor is trying to use)

dbus-monitor

dbus-monitor(1) 					      General Commands Manual						   dbus-monitor(1)

NAME

       dbus-monitor - debug probe to print message bus messages

SYNOPSIS

       dbus-monitor [--system | --session | --address ADDRESS] [--profile | --monitor] [watch expressions]

DESCRIPTION

       The  dbus-monitor command is used to monitor messages going through a D-Bus message bus.  See http://www.freedesktop.org/software/dbus/ for
       more information about the big picture.

       There are two well-known message buses: the systemwide message bus (installed  on  many	systems  as  the  "messagebus"	service)  and  the
       per-user-login-session  message	bus (started each time a user logs in).  The --system and --session options direct dbus-monitor to monitor
       the system or session buses respectively.  If neither is specified, dbus-monitor monitors the session bus.

       dbus-monitor has two different output modes, the 'classic'-style monitoring mode and profiling mode. The profiling format is a compact for-
       mat  with a single line per message and microsecond-resolution timing information. The --profile and --monitor options select the profiling
       and monitoring output format respectively. If neither is specified, dbus-monitor uses the monitoring output format.

       In order to get dbus-monitor to see the messages you are interested in, you should specify a set of watch expressions as you  would  expect
       to be passed to the dbus_bus_add_match function.

       The message bus configuration may keep dbus-monitor from seeing all messages, especially if you run the monitor as a non-root user.

OPTIONS

       --system
	      Monitor the system message bus.

       --session
	      Monitor the session message bus.	(This is the default.)

       --address ADDRESS
	      Monitor an arbitrary message bus given at ADDRESS.

       --profile
	      Use the profiling output format.

       --monitor
	      Use the monitoring output format.  (This is the default.)

EXAMPLE

       Here is an example of using dbus-monitor to watch for the gnome typing monitor to say things

	 dbus-monitor "type='signal',sender='org.gnome.TypingMonitor',interface='org.gnome.TypingMonitor'"

AUTHOR

       dbus-monitor was written by Philip Blundell.  The profiling output mode was added by Olli Salli.

BUGS

       Please send bug reports to the D-Bus mailing list or bug tracker, see http://www.freedesktop.org/software/dbus/
