Xfree and different refresh rates.

[vash]

Alrite, here goes.

I've got Xfree 4.2+ running from Gentoo and its working quite well with the Nvidia driver. My main question is, how do you specify a different refresh rate for a different resolution? Under X, I am running 1600x1200@85hz. That resolution is just too high for most games, so I usually play at 1024x768. At 10x7, my monitor definitely support 120hz and I want to run X at that resolution.

Anyone?

In xf86config you can specify a min and max vertical refresh rate.
Re-run /usr/X11R6/bin/xf86config and when it asks for a vert refresh choose the option that allows you to input your own range.
Make sure of the numbers you use here as you can overdrive a monitor.
Once done do a nano -w /etc/X11/XF86Config and scroll down to the screens section.
You should see several resolution and color depth sections. Edit those for the min and max resolution you want to run.
Save the file and restart X. To change resolutions do a Cntrl+Alt and + ot -.

Been there, done that. I know the min and max's of my monitors range and those values are present in the xf86config file. When I run the desktop at 16x12, the refresh is exactly what I want: 85hz. But when I tried to play Quake3, the resolution is 1024x768 and at 85hz. I would really want 10x7 to be 120hz (which the monitor supports), but Xfree seems to stick with 85hz for all other resolutions (640x480x, 800x600, etc). There has to be a way to override what Xfree determines is the best for a specific resolution.
