Screen modes

[spamse]

Thanks for getting the Nvidia package sorted - I am finally running my
old Riva TNT card with the proper Nvidia drivers, and all is smooth.

Back on to what seems to be a common issue, screen resolutions. I have
followed previous instructions, but am still having difficulties. I
have modified my xorg.conf (see below) details to match the monitor's
spec (Dell ES-17), but the resolutions available do not match my
entries. Only the following are listed:

1024 x 768, 800 x 600, 640 x 480, 1152 x 864, 832 x 624
and refresh rates of 85/75/70/60/87

Why do these not match my xorg.conf, and where do the extra settings come from?
