How to change resolution of login screen (i.e. gdm)?
On my old (Fedora) system when I changed the system resolution it
changed it for everything, including the gnome login screen. This
doesn't seem to happen with Ubuntu, the login screen stays obstinately
at a rather low (and grotty) resolution and only when the user desktop
starts up does it switch to my normal 1600x1200.
Is there no way to avoid the resolution switch between logon and user
desktop?

System/Administration/Startup-Manager
If Startup-Manager isn't there, install via:
System/Administration/Synaptic Package Manager
You can do many things there including limiting the number of
kernels shown at boot (Advance tab). This was a question from
a different thread.

Not quite what I wanted (but very useful now I have installed it).
The Startup Manager allows one to set the graphics mode for the boot
loader display(s), grub, etc. What I want to do is to set the display
resolution for the gdm login screen, maybe there's a gdm configuration
utility.

Sorry, I thought the Startup-Manager settings carried over to the
GDM Login window.
There is a GDM config utility (System/Administration/Login Window)
but I don't see a resolution setting. I have not dug into it much
because I know some of the setting don't work. e.g.:
Set the clock to 24hr doesn't work.

Cool! That lets me select whether to use the -386 kernel or the -generic
kernel as default - thanks.
@Chris: use the following to set for your specific monitor:
gksu displayconfig-gtk
Log off and then log back in. Once you've done that:
gksu gedit /etc/X11/xorg.conf
and modify the "Virtual" settings this section to your proper screen
settings (1600 1200):
Test that first (logout/login), and then you may also wish to modify the
depth settings as well depending upon what grapic card you have - I've
found on certain Intel & ATI cards, setting to 16 instead of 24 enables
dri and speeds up my glxgears on those cards by a factor of about 2.

displayconfig-gtk isn't available for 8.10 as far as I can see.#

You didn't say you were running a beta version of Ubuntu.
*Please* put [Intrepid] in the subject line if you are using Intrepid so
that folks running standard released versions of Ubuntu do not waste
their time offering suggestions on something they may no have installed,
and so those that *do* have Intrepid installed can help instead.

The above didn't work (xorg.conf didn't parse) but the changes below
do it for me:-
Nothing else in xorg.conf is changed, all I have added is that
Modeline and Option.
This is an important issue I think with the new Xorg which has no
monitor settings in xorg.conf, if the resolution that it defaults to
is wrong (or not what the user wants) there appears to be no user
friendly way of changing it.
