Screen refresh rate...


Hi,

I am relatively new to linux... I am having trouble resetting the refresh rate for my video...

I downloaded RH8.0 and installed it on my pc, but I can't get the refresh rate to go higher than 60Hz... I would really like to get it over 70Hz so I don't get sick from the flicker.

I have looked into the default /etc/X11/XF86Config file looking for a modeline, but I don't see one.

Are there any suggestions on how I can change my refresh rate?


Here is some system info that might be useful (limiting?)...
Processor: AMD Athalon XP 1700+
MEM: 256 MB
Video Card: GeForce4 4200 Ti (64MB)
Resolution: 1280x1024

try this site, it might seem a bit of a hack to you, but it works very well. http://koala.ilog.fr/cgi-bin/nph-colas-modelines

I haven't tried the nvidia drivers yet... they didn't show anything keyed to redhat 8 so I wasn't sure if that would mess something up. Maybe I missed it... I'll go back and look.

The problem with the sites that generate modelines is that there doesn't appear to be anything in my XF86Config file resembling a modeline. Have they discarded this? How do I add one? I don't think I can just drop it in the file any-ol-place, right? Is there a quasi decent tutorial out there that might make a good newbie reference to fixing this file?

Also, I've seen XF86Config-4 files in previous distributions... but this one doesn't seem to have it. Is this a new thing?

Thanks!

XFree86-4.x.x and later read the info directly from your monitor and set up the highest supported refresh, go to the nvidia download page and get the latest kernel and glx files in .tar.gz format, install then as per the instructions in the README file in the glx package.

you need to add the mode lines, that's why it creates them for you. for example
Code:
EndSection

Section "Monitor"
    Identifier "Monitor0"
    VendorName "Monitor Vendor"
    ModelName  "Monitor Model"
    HorizSync  31.5-48.5
    VertRefresh 50-70

Modeline "800x600"      40.00    800  808  936 1012    600  601  605  668 +hsync +vsync
Modeline "640x480"      25.20    640  652  748  780    480  482  484  521 -hsync -vsync

EndSection
