Hertz problems!


Hello! I've got some problems configurating my xorg.conf.

What i want is to be able to run 1024x768@85hertz, 800x600@100hertz and 640x480@120hertz. I know that my monitor allows it because it works in windows perfectly!

I've filled in the correct HorzSync/VerticalRefresh values. (Hsync=31.0 - 72 and Vresfresh= 50.0 - 120) in the config. When i start fluxbox, it runs in 1024x768@85hertz (And thats what i want), but when i start a game (quakeworld) it goes to 800x600@85hertz.. And that's where i would like 100hertz. Is there a way to specifie a certain hertz for a certain mode?

your monitor support 100Hz but what about your graphics card. If it cannot go up to 100Hz then it just isn't going to happen

try setting it to 800 by 600 while in a normal window. See what it gives you for the refresh rate. it is possible that the game has a refresh rate built into it. in that case you should be looking in the prefrences for your game

have you checked the compatability of your card with your distro. I took a quick look in the HCL and did not find it. There are still not enough reviews in the HCL for it to be reliable.

but you can take a look at http://www.linuxcompatible.org/ . it may only be supported up to 85 Hz

after a bit more searching i found it here . It looks like it is compatable. However it states that you need the latest drivers. Have you tried updating the drivers?

Go to http://xtiming.sourceforge.net/cgi-bin/xtiming.pl. Then enter the monitor specs and your desire resolution at a desire refresh rate. Then copy and paste the modeline in the monitor section of either /etc/X11/XF86Config, /etc/X11/XF86Config-4, or /etc/X11/xorg.conf. Next if you are in runlevel 5 or 4, hit CTL+ALT+BKSPC or just exit out of X Window Server when running in runlevel 3. The first modeline for each resolution will be used first. If the first one is not correct, it will go to the next modeline.

No, the refresh rate and resolution is not dependent on the module (driver). It is dependent on the hardware by the RAMDAC. Though check the maximum settings you can use in the nVidia's readme file for Linux.
