I have an Ultra 60 with 2 ffb2+ frame buffers (model # X3670A) and 2
Viewsonic VE170b flat panel monitors. I am running Solaris 9 with the
latest patch cluster and am trying this using the CDE window manager.
The monitor cables are identical as well. (I am using VGA adapters)

The problem:

When the X server starts, the primary screen /dev/ffb0 comes up under a
lower resolution then /dev/ffb1, even though everything is identical. If
I explicitly change the resolution of ffb0 after the X server is already
running ('ffbconfig -dev /dev/ffb0 -res 1280x1024x67 now') the screen
changes resolution and the window manager shrinks and looks distorted.
However, if I log out and then immediately log back in, viola, it is
perfect. Both screens are at 1280x1024x67. If I reboot or restart the
Xserver, I am back to square one.

Here is what prtdiag lists the frame buffers as:

0 UPA 113 29 FFB, Double Buffered
SUNW,501-4788
0 UPA 113 30 FFB, Double Buffered SUNW,501-4788

I created /etc/dt/config/Xconfig and /etc/dt/config/Xservers. In
Xconfig, I changed the following:

Dtlogin.servers: /etc/dt/config/Xservers

Here is what Xservers conintains:

:0 Local local_uid@console root /usr/openwin/bin/Xsun :0 -nobanner
+xinerama -dev /dev/ffb0 -dev /dev/ffb1

I have made sure both ffb devices have the exact same settings.

ffbconfig -dev /dev/ffb0 -res 1280x1024x67
ffbconfig -dev /dev/ffb1 -res 1280x1024x67

Next I removed the +xinerama setting and started X with two different
screens. I then ran xdpyinfo on each screen and the output was identical
with the exception of the different screen number and etc.. (basically
did 'xdpyinfo > screen0' and 'xdpyinfo > screen1' and then 'diff screen0
screen1')

Even with both cards set to defaults, here is what I get:

ffbconfig -dev /dev/ffb0 -defaults
ffbconfig -dev /dev/ffb1 -defaults

ffbconfig -dev /dev/ffb0 -propts
--- OpenWindows Configuration for /dev/ffb0 ---

Now here is the part that I do not understand. When I set each board to
it's defaults and then examine the supported resolutions, they differ.

hurley:~ #ffbconfig -dev /dev/ffb0 -res ?

1280x1024x67 *
1280x1024x76 *
1280x1024x85 *


Can anyone shed some lights on my dilema? Do I have a faulty frame
buffer? I know the resolution I am trying works find on both monitors.

Thanks for any help, sorry this was so long.

Obviously, the frame buffers do not get/have the same information
about your monitors, as is made evident by the ffbconfig
output. The asterisks indicate resolutions not supported by
the monitors. ffb0 is listed as only capable of 1152x900x66, whereas
ffb1 shows the more reasonable 1280x1024x60 (plus the lower
resolutions). Try to run ffbconfig with the -prconf option to
see what the monitor type is (I guess that for ffb0 it's
"Unknown", which would make it default to a Sun 19" FF monitor
with one one resolution possible).

Take care

Here is the output of those commands, you were correct, it thinks one is
a Sun monitor and one as Unkown. Why would it do this? They are both the
same monitors, same video boards, same cables. How can I correct this?

Also, one thing different. The vga adapters for the video cards are
different brands, one is from Sun I believe and the other from some 3rd
party. Could this be an issue? Doesn't make sense, as I believe there is
no 'logic' in the adapter, just merely copper connections, or am I wrong?

As the Xsun man page states, you need to specify the +xinerama flag
to enable xinerama.

Yes, I know, it does not work under Solaris 9 with my config. The
screens flicker black then white and then I am dropped to a console login.

I have tried placing the +xinerama option in several different places
after the /Xsun above and same thing. I saw some posts on google where
people said the positioning of the +xinerama option sometimes mattered,
as in one guy claimed the -core should go before.

Anyway, I think the problem is related to the system thinking the two
monitors are different.
