Unhappy GeForce4 MX440 at 1152x864

Hi,

I'm having trouble getting X to run at the resolution that I want, i.e. the res that I can run Win98 at: 1152x864x24 @ 75Hz.

I can get it running at 1024x768 no problem (doing so right now), but I'm having trouble getting any kind of modeline working for 1152x864.

The problem I'm getting is strange: if I run XFree86 from the command line I get the logo appearing normally, but when the grey hash comes up, I get this:

+-------------------------------------------------------------------------------+
|................................................. ................................|
|----------.................................................. .....................|
|..........-----------.................................................. ..........|
|.....................----------.................................................. |
etc., where .... is the grey hash, and ---- is the white of the nvidia logo.

Textually, what's happening is that the first row appears ok, the first 128 pixels (=1152/9) of the second row is displaying the logo buffer, pixels 128-256 of the third row the same, etc. and then it wraps around again. It's as if that the card or X or something is saying that the lines should be 1280 long and so should have 10 blocks of 128 instead of 9, but this is just my uneducated opinion. If I run startx to bring up KDE, then the bits of the logo that are left behind are still there, but the desktop itself is scrambled. The mouse cursor is unaffected by all this.

I have a generic no-brand monitor so I don't know the actual specs, but as I said earlier I have my target res running fine under Win98 so I didn't think this was a problem. If somebody knows of a util for Windows that will let me generate a modeline based on the current settings, this would be a greatly useful.

My specs:
AGP Leadtek GeForce4 MX440 - 64Mb DDR
1.0-4496, although I had this problem with an earlier version (4363)
LFS Distro running 2.4.20, XFree 4.3
Bios: 04.17.00.28.00
Pentium II-300

Sorry for the long winded message, but I've found nothing on the net relating to this problem, and I've gone through several modeline calculators and nothing has helped me.

Cheers,
Chris.
