You were right! I get the same problem with another monitor. What
can I do about the driver? I got my basic configuration file with
X -configure which obviously determined the necessary driver by itself. Would it help to upgrade xfree ?
Re: William Gallafent
I tried your less "challenging" parameters, however, again without success. Somehow the only mode which seems to work is "640x480" as long as I don't give HorizSync and VertRefresh values.
Interestingly I had a working display before installing Debian 3.0!
Thanks again to your replies! Christian.

These specifications are that of a multisync monitor, so it should sync to any default mode that XFree86 picks for it if you have filled in the HorizSync and VertRefresh appropriately in the XF86Config file. Other info on the web that I see confirms the specifications of:
HorizSync 30 - 121 VertRefresh 48 - 160
It sounds like you have a problem with the monitor or graphics
card or graphics card driver (most likely the later).
Do any modes work correctly?
You might want to try borrowing another monitor to see if you get the same problem on a different monitor. I would guess that you would, and that it's a driver problem.

I have a 21-inch Sony GDM-5402 monitor connected to my LINUX computer (ELSA Gloria XXL graphics card; 3Dlabs chipset pm2v). I recently installed a new LINUX version (Debian 3.0r2) with XFree Version 4.1.0.1. Unfortunately I'm not able to find a proper working configuration for my monitor. With the attached XF86Config-4 file I tried to leave finding of a proper configuration to the X-server. With this I only get a "640x480" screen mode. When I give the correct HorizSync and VertRefresh data in the monitor section the XServer also finds other modes (default "1280x1024") which, however, are nor working properly. I tried to calculate ModeLine parameters (e.g. http://xtiming.sourceforge.net) with the specifications given in the manual of the monitor, but also could not find a working configuration. Since I already spent too many hours with that problem I would be grateful if anybody would have some suggestions for me!
The monitor has the following specifications: - recommended resolution: 1600x1280 - deflection frequency: horizontal: 30 to 121kHz vertical: 48 to 160 Hz - Plug and Play: DDC1/2B/2Bi, GTF
The recommended horizontal and vertical timing conditions for the monitor are:
- horizontal sync width duty should be more than 4.8% of total horizontal time or 0.8microsec, whichever is larger.
- horizontal blanking width should be more than 2.3microsec
- vertical blanking width should be more than 450micorsec.
Thanks in advance! Christian.
