Strange Dual Screen behaviour

trscookie · 02-23-2007, 05:15 AM

Hello all,

I am having the weirdest Dual screen issues; I have a Laptop a Toshiba Tecra M3 and I have another 17" LCD screen plugged into the laptop.

When its just the laptop monitor on its own the screen is nice and bright and you can see everything fine - all works well.

However when I have my LCD 17" monitor plugged into my laptop the laptop monitor is really really dark and you cant see much.

I have once seen the monitors working fine together but I rebooted the machine and it hasnt worked since?!?! This is my Xorg file:

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
