Unhappy Xtreme Newbie: Higher CRT Refresh Rate


In windows, I run at 1024x768@100hz. I have only been able to get 1024x768@8?hz in linux. I've tried PCLinuxOS 9.2, Mandrake 9, Mandriva 2006, and Damn Small Linux 2.2 rc1. 8?hz really "hz" my eyes, know what I mean, which is the main reason I'm still stuck here in Windows

Is this a linux or a linux driver limitaion or something I don't know about? Has anyone else hit 100hz? I would even settle for a lower screen res at this point.

I sure do appreciate any kind of help from anyone on this matter.

Thanks for reading this.

You need to enter the modeline for the desired resolution and refresh rate in /etc/X11/xorg.conf Go to this web site: http://www.sh.nu/nvidia/gtf.php and enter the resolution and refresh rate you would like. Take the modeline it gives you and paste it in /etc/X11/xorg.conf in the Section "Monitor" just below the line starting with "VertRefresh" and above the line "EndSection". You also need to make sure you have the correct horizontal and vertical refresh rates for your monitor. The refresh rates should be listed in technical documentation for your make/model monitor.

Thanks. I did that (and bookmarked that website!).
I am running PCLinuxOS 9.2 as I type this. I used the Synaptic Software Manager to update my GeForce 5700LE drivers. What I did was change the hor and vert ranges from a Dell P990 (h30-96/ v48-120) to those of a Dell M990 (h30-96/ v50-160) and it worked. The P990 is capable of 1024x768@100hz but it's as though linux didn't believe it. Weird. Now I have to get Yet Another NVIDIA Configurator" to run w/o the Permissions error, but will be another post if necessary.
Thanks m_yates, for the help and the cool link.

Cool! This worked for me on my Dell 1280x800 60Hz; I was sitting with a slightly less 58Hz, I have not noticed the difference? Is there a way to detect the change??

Tah!

Look into the /var/log/Xorg.0.log file for a line like this.

Code:
Validated modes for display device CRT-0:
The next line should be the showing you the rate and resolution you are running at like this.
Code:
Default mode "1600x1200": 229.5 MHz, 106.2 kHz, 85.0 Hz
The end value is the refresh rate. Another way may be if your monitor has an OSD (on screen display) for its settings is to use that and go into the section for your current settings it will tell you there if it is supported not all monitors have this though.
