Default 3 monitors (anyone good with xorg.conf?)
Okay, so I got an extra CRT monitor for 5 bucks and I have been having a little trouble setting it up. I have two nVidia cards (one AGP and one PCI) and the AGP one is currently handling my middle and leftmost monitors (using TwinView). I have edited my xorg.conf file a few times to attempt to get it to work, but X always fails to lauch. I was trying to use both Xinerama and TwinView so I could still have 3D acceleration. It will work according to this site (http://pwp.netcabo.pt/0150048402/lin...iple_Head.html) but it is hard to follow his example (he used 4 monitors). I would appreciate it if anyone could tell me what changes I need to make to the Xorg.conf file (please be specific, I am not too good with it). Here is my current one with 2 monitors:
Code:
# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

Aha! I got it working! I just manually edited my file, but thanks for that link, jake, I copied a bunch of parts from that xorg.conf file. Here is my end result, if anyone cares:
Code:

#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.

# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
