Re: [foxboro] D-style Sun box loses video

Duc,

You could try deleting /dev/fb*  and then shutdown / halt / boot -r

I think the video drivers are only re-built when they are not there.

(Ok, rename the files with the mv command if you don't want to delete)

Objet=A0: [foxboro] D-style Sun box loses video

Hi list,

Another day, another problem.

I have an AW51D (Sun Ultra 5) with dual-head video. Recently it lost the
video out from the primary video port, but in a peculiar way.

I can see all the POST messages (on white background) fine until the
Foxboro I/A signal kicks in (when the screen normally turns to the light
blue background), then I get nothing but a dark screen. The box would
continue to boot up fully and I can see the video signal on the
secondary display.

I pull the hard drive and put it into another Ultra 5 box, but the same
symptom persists, so I ruled out hardware problems and started to look
at corrupted graphic drivers or something along that line.

Searching the foxboro archive (from another problem of mine three years
ago, http://www.freelists.org/archives/foxboro/03-2003/msg00042.html)
led to inspecting the graphic driver in /dev/fb0, but that didn't shed
much light (it's there, and looks similar to that on an operational
box).

Searching Google for graphic problems with the Ultra 5 really didn't
help much as this problem rears its head when the display is switched to
the Foxboro graphic signal.

(Yes, I've tried 'boot -r'.)

Anybody experiences this same problem? Anybody knows how to fix it?
Thanks for any information.

Duc
