Changing default resolution on XVR-100

Question

For the life of me I cannot find out how to fix this.
I have a XVR-100 installed in a V440. I am unable to administer it via our KVM because the default resolution is way to high. When I change it, it of course screws up the screen and I have to reboot. fbconfig is not setting my desired resolution as the default.

That resolution is unsupported for me. How do I tell oenwindows to use 1024x768 with a 60hz refresh?
Thanks

From the provided information, I cannot tell whether you are using the HD15 or the DVI port. Furthermore, it is somewhat unusual to be using pfb1 unless you have more than one XVR-100 installed.
By default, the system will probably be looking at /dev/fb. Let's get the Sun to redo the video devices (this will trigger a reboot). Do this as root:
rm -rf /dev/fbs; rm /dev/fb*; touch /reconfigure; init 6
Do not try to use devfsadm for this step! Do the reboot!
When the system comes up, you should have a newly discovered video tree with your XVR-100 as the default video card pointed at by /dev/fb. If you have multiple video cards then you have more complex commands, but I am going to move forward assuming the simple case of one video card using HD15. If you are using a DVI connection or have more video cards, make appropriate changes to the following (PS: I do not read these boards often so you cannot count on me responding to a follow-up).
Let's set the video mode first. Do this as root:
eeprom output-device=screen:r1024x768x60
fbconfig -res VESA_STD_1024x768x60 try nowThe screen will get distorted, but as long as you get a screen, agree to take the setting and reboot the system. When the system returns, you should have the lower resolution. This probably does not solve your (implied) color problem, though.
To fix the color we need to change the configuration DT configuration. I am assuming that you have no configuration for DT. These steps may obliterate an existing configuration.
mkdir -p /etc/dt/config
cp /usr/dt/config/Xservers /etc/dt/configModify the last non-blank line in /etc/dt/config/Xservers by appending this to the end:
-dev /dev/fb defdepth 24The modified line would look something like this:
   :0   Local local_uid@console root /usr/openwin/bin/Xsun :0 -nobanner -dev /dev/fb defdepth 24Reboot the system again and when it comes up, everything should be fine.
