Xorg, refresh rates, modelines
GenuineAdvantage:
I can't seem to find a way to raise the monitor refresh rate in x server. I am trying to make it so the max refresh rates are 120Hz in 640x480 and 1024x768. and 85Hz at 1280x960 (and pretty much any above that). These are the max for each detected by windows for this monitor and they work. The monitor can handle it, 120Hz is the max up to 768 vertical. But I don't know if and how this can be done in x server running linux. I tried some modelines settings in xorg according to some instructions, but they didn't work too well. In fact 640x480@120 became available, but it wasn't the same as in windows. I can even tell because the center settings I had set in windows were not saved to the monitor and it just didn't seem right in the xserver version. Seems kind of complicated to me, though I've heard of people pulling it off to play Quake 3 a while back.
Let me just clear up what I've done so far since the beginning so I don't get the obvious, which I've already done. At the start I had only 60Hz and only 3 resolutions avaiable. When I ran the monitor detection ddcprobe and grep monitorrange, I put the appropriate settings in xorg. Since then I get 85Hz tops, which is good but the monitor can go up to 120Hz. Which also matches well with scrolling designed for 60Hz in the first place.
Any ideas?

xorgcfg?
Also, next time, tell us what distribution you're using, and what videocard.
H_TeXMeX_H:
And what drivers ... some drivers (experimental ATI Linux drivers) don't support the refresh rates that you might get with Window$.
GenuineAdvantage:
Sorry I was out of it. Yes, xorg.conf. The drivers are the official nVidia drivers 7667. The card is a Geforce 4 MX which even has TV OUT and is enabled. So I would be really surprised if the driver didn't support 120Hz properly, but I don't know it's possible. The distro I use, right now I'm in Ubuntu even if I multi boot others, and their setups for it was basically the same. But for the sake of argument let's stick with Ubuntu (5.10).
