Description Joshua Ginsberg 2004-09-13 21:28:43 EDT
I've been trying to configure a multiheaded setup for my new
workstation which has an onboard AGP i810 video controller and a PCI
Voodoo3 video controller. When I configured it in Multihead mode, when
X starts, the entire machine reboots. I tried configuring it for
singlehead using only the i810, and when X starts, the entire machine
reboots. I tried configuring it for singlehead using on the tdfx, and
when X starts, all is well.

The /var/log/Xorg.0.log file gives no information of any help. Running
Xorg -probeonly does not yield any error that would shed light on the
problem. I don't know what other debugging steps I can try.

I've tried upgrading to the latest Rawhide version of the server
( and the problem remains.

Please help! I need multiheaded for my work!

Okay, update.

Now the i810 doesn't crash the entire system -- it just blanks the 
screen with a white square as my mouse cursor, locks up the keyboard, 
crashes X, and won't give me control of my video anymore.

However, once I physically remove the tdfx hardware, all is well with 
the i810. It works just great.

Is it a memory conflict of some sort?

If 3Dfx video hardware is used in a multihead system, it must
be configured to be the "Primary" VGA device.  You need to go into
your BIOS CMOS settings and set the onboard video to be non-primary.

This is either a complex long standing bug in the tdfx driver, or
it is a 3Dfx BIOS bug.  Nobody has ever debugged the issue that
deep to draw any conclusions however.

Let us know if setting the 3Dfx to be the primary VGA device

Comment 3 Joshua Ginsberg 2004-09-14 03:21:45 EDT
In the examination of the problem above, the 3dfx acts as the primary
graphics adaptor. There is a BIOS setting for selecting PCI vs. AGP as
the primary, but it seems to have no affect. Console always appears on
the 3dfx card and /etc/X11/xorg.conf treats the tdfx device as the
primary device. The i810 device has BusID but tdfx device does not.
