I'm not aware of any split config for Xorg, but that does look unusual -
particularly because no video driver is defined. I guess it must just pick the
first driver that works.
You could try just adding the metamodes line, though you might find
that you then
need to configure the monitor to have the right VertRefresh and
HorizSync, so I'd
give the 'Xorg -configure' option a go and see if that gives you a less bare
template. With any luck it'll fill in those options by querying the monitor.

How
do I get a Samsung SyncMaster 931BW to operate at 1440 x900 on 9.10? I
have tried setting up xorg.conf file but this does not work - must have
it set-up wrong it just causes the computer to plink at a text log-in
sign.
Re: low resolution after 9.10
installation
I used this
xorg.conf (got this from a forum)
Content of my xorg.conf - below: and lshw output below.

Sorry, forgot to add that you have no Intel 945G in your machine (you
have an SiS 771/671 PCIE VGA Display Adapter, so trying to use that
xorg.conf won't work anyway. Note: xorg.conf is not used in 9.10 by
default & will only be used if you add one.

Can you describe how it refuses to run, do you click on the
application and nothing happens?
If you're comfortable with the command line xrandr is a tool that will
allow you to change your screen resolution. 'man xrandr' for more
information.

The gnome screen resolution application is 'gnome-display-properties'
try running that in the terminal and posting the output. Don't install
anything if it asks you to.
If the graphical screen resolution application is broken then the next
step is to run 'xrandr' in the terminal, please post the output of
that command also.

xrandr thinks that your maximum resolution is 800x600, given the
monitor/video card combination you're using. You may need a different
monitor.
Can you run 'cvt 1024 768' in the terminal and post the output back?
Thanks.

Run 'cvt 1024 768'
Notice there's no X.
