- OK, here's the situation. I got a Sparcstation 10 running
- SunOS 4.1.3, and I need to get more than one monitor attached
- to the machine (initially just two). I have two Sun GX boards
- and they seem to install just fine (no errors on boot up, and
- they seem to be recognized by the OS).
- I know that the hardware configuration works because the
- whole setup works just fine with Openwindows by doing the
- command:
- `openwin -dev /dev/cgsix0 -dev /dev/cgsix1`
- everything comes up fine.
- However, if I try to start up the MIT X server (X11R4) along with
- Motif, only one monitor comes up and the other remains dark.
- Now for the really strange part. It won't work with two cgsix
- cards in slots 2 & 3. It won't work with two cgthree cards in slots
- 2 & 3. It won't work with a cgsix card in slot 2 and a cgthree
- card in slot 3. However, it WILL work with a cgthree card in slot
- 2 and a cgsix card in slot 3!
- Sun hasn't been much help as they really only support their
- Openwindows environment. I'd really like to know what's going
- on 'cause we're probably going to need at least one more monitor
- on a Sparc 10 by the time this is over, and the extra speed of the
- cgsix would be nice for our application.
- If anyone has any clue as to why this is behaving this way, I'd
- love to hear from you. Please E-mail any response and I'll post if
- there is any resolution.
- Thanks.
