You can consult ESR's howto at: http://en.tldp.org/HOWTO/XFree86-Video-Timings-HOWTO/ and other places on the net. Programs like gtf, which comes with XFree86 since version 4.3.0, can produce modelines for multisync monitors. Eg. $ gtf 800 600 90 # 800x600 @ 90.00 Hz (GTF) hsync: 56.88 kHz; pclk: 60.07 MHz Modeline "800x600_90.00" 60.07 800 840 928 1056 600 601 604 632 -HSync +Vsync But it won't match both horizontal and vertical sync contraints. It will only target a vertical refresh rate. As you can see, this one is nearly 57 kHz, while you have specified 54 kHz. BTW. 90 Hz is an odd refresh rate for a fixed frequency monitor, so I have a hard time believing that is an accurate specification. A monitor with a 54 kHz horizontal sync rate and a 90 Hz vertical sync rate wouldn't be able to do resolutions with more than 596 lines.
