Public bug reported:
I was using Ubuntu 8.04, and I upgraded to 8.10, then 9.04.
With 8.04, I was using sym links with the below xorg.conf file and it was
working fine. When I upgraded, I don't get dual monitors (one being the
extension of the other). I do however, get a mirrored screen (which I don't
want).
The display settings doesn't recognize the monitors at all (They are "unknown").
here is the xorg.conf:
# /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
