Hi All,
I have been fighting my nVidia resolution problems for a while and hope someone can answer a few questions.

My monitor is apparently not auto-detected and the xorg.conf has invalid data for it.
I managed to install the nVidia drivers for my GEForce 6100 and it gave me a long list of resolution options and 3D acceleration is working but the refresh rates appear to be incorrect.
When I select 1280x1024 it sets the refresh to 51 and my monitor only supports down to 56. Consequently I get a thin line of light at the top of the screen as the only output.

I edited the xorg.conf file to change my monitor frequencies to
Horizontal:30~79KHz
Vertical :56~75Hz
It does not seem to have had any impact so I assume there are settings for the nVidia driver that need tweaking or at least for the resolutions that Ubuntu (8.10 i386) offers me.

What file/section would I modify for the video resolution options?
What entries in xorg.conf would I setup to set the logon screen resolution? Currently I get the same thin line for video but after I enter my id/password it loads the desktop and changes to the desktop resolution.

I am close to getting this working, just have to alter the resolution/refresh rates to match what the monitor and video processor actually support.

Thanks.

You're on the right track. xorg is where you would configure it. Sintax is important though.
Post your xorg.conf.
Resolution on bootup is a pita (for me, anyway) so I disabled the graphic. I find it more entertaining to watch the terminal printout while it's booting anyway...
