X.Org horizontal screen position setting

[Alex]

Hi all,
I recently attached my Kubuntu machine to a new monitor, and ran
dpkg-reconfigure xserver-xorg to configure X server for the new monitor..
The screen size and refresh rate is now working fine, but there is a problem
with the horizontal position of the display, leading to a a black strip down
the left of the screen, and the right side of applications being cut off.
I can fix this by adjusting the horizontal position in the monitor menu
(settings buttons on the monitor) but this since this monitor on a KVM this
will cause a problem with the windows and MAC machines using the monitor.

I'm sure this must be a setting somewhere in the X config files. I have
looked throught /etc/X11/xorg.conf , /etc/X11/startx and other files as
well as man pages but can't see anything. Google turns up nothing.
Does anyone have any idea where this settiing might be?
Thanks in advance.

Alex.

Hi Alex,
I have seen this from time to time and it's usually been the refresh rate
being off a bit one way or the other. On breezy you can often fix it in
the System > Preferences > Screen Resolution applet. If that doesn't allow
you to change the rate, at least you should be able to check that it's
using what your monitor suggests.

You could try the utility xvidtune, and change the settings to centre X.
Note the settings, and write them into your xorg.conf file.
