cant set monitor refresh rate (RH 9)


please help.... if i cant change this refresh im going to have a seizure.

Ive searched a bunch of forums, but no fixes...

I got an appropriate modeline from a website and included the following in the monitor section of the XF86Config

Modeline "1280x1024" 185.64 1280 1376 1600 2024 1024 1024 1028 1079

Ive pasted the contents of the file here.... please help. what am i doing wrong? The RedHat display setting app allows me to set horizontal and vertical ranges, but not actually choose one specific setting.

Im using 1280x1024, RedHat version 9.

A V-freq: 85.00 Hz with the same monitor on my XP box works fine, but i can tell its not going to that on the linux box.

Thanks in advance.

Josh

Okay, what is your log output from XFree86? ( /var/log/XFree86.0.log )

The problem could be that the i810 chipset can't support 1280x1024x24 at 85Hz

ive never looked in this log, but it sounds like what youre saying might be right on the $.

in the log here, it attempts to use 85 Hz for all the resolutions. Does this mean that my only solution might be to use a different (lower) resoultion?

i appreciate your help.

Could be try dropping the resolution or the depth. The integrated graphics chip might be able to use 16bit at 85Hz. Or as you said drop the resolution too 1024x768.

I'm currently on 60 for my 1280x1024 but for games I drop to 1024x768, which brings me up too 85.

I've had exactly the same problem on my last Mandrake box with an old CRT. It turned out it was the monitor so I broke it with obsene delight.
