I am trying an experiment and getting dual monitors working on a system 
using two video cards. the video cards are the onboard S3 Savage and a 
S3 Virge PCI card. lspci yields:
00:05.0 VGA compatible controller: S3 Inc. 86c325 [ViRGE] (rev 06)
01:00.0 VGA compatible controller: S3 Inc. VT8375 [ProSavage8 KM266/KL266]

Trying the easy route I run
Xorg -configure

which I check and all seems ok, but when I try Xorg -config 
/root/xorg.conf.new screen 0 goes blank with a "-" in the upper left 
hand corner, and then nothing. I cannot even get another terminal screen 
using cntrl-alt-1, etc. I have to ssh into the system to reboot.

Now, if I comment out Screen 1 in the Screen Layout scetion X runs fine 
on Screen  0. Here is the xorg.conf that works.

Now, there is are a couple of warnings in the log file, but these are 
there no matter if screen 1 is enabled or not, i.e. screen 0 only and X 
running properly
(WW) AllowEmptyInput is on, devices using drivers 'kbd', 'mouse' or 
'vmmouse' will be disabled.
(WW) Disabling Mouse0
(WW) Disabling Keyboard0

Any help?
