anyone know how to achieve 75hz specifically for 800x600 in xorg 7? my video drivers are already configured and its defaulting to 85hz for some reason. there are no modelines in the current xorg.conf. any ideas?

Think there are modes are called 800x600_75, 800x600_85, etc, at least with nvidias drivers, but probably with xorgs built-in drivers as well. You should check your xorg-logs (using startx -- -logverbose 6).

faustov, thanks for the suggestion but ive already tried that exact modeline. something is over-riding it. it still defaults to 85hz for all resolutions even when specified in ezquake-gl.glx command line (vid_displayfrequency). :-\

Not ur case?

Dude. You have to create the modelines you want. I made this one for you, so you can paste it in the right part of xorg.conf. Now, within your windows manager, like gnome or KDE, you have to pick the reslution@refrate that corresponds to that modeline. But that is not all, you also have to set your CMDline so it starts your ezQuake with the same resolution@refrate settings. That's the only way to make it work.

good luck

I think your wrong, you had to create modelines before. I have not created any of these nor the _60 or _85 ones I have either.

ive already created modelines for that particular resolution and they came out exactly like the ones you sent me, do i have to create modelines for EVERY resolution? mabey thats why its not working(?) either way i still dont see anything setting it to 85hz , why would it default to such a high rate? am i missing a secondary xorg.conf or something?
edit: also i have tried the gnome panel and it still only shows 85hz for each resolution. also the ezquake-gl.glx command line is as follows.
./ezquake-gl.glx -conwidth 512 -conheight 400 -width 800 -height 600 -noswapctrl -bpp 32 -heapsize 64000 -zone 4096 -norjscripts -noforcemaccel -noforcemparms +cfg_load daxdef +set vid_displayfrequency 75 +vid_vsync 0

here is the monitor section of my xorg.conf

Section "Monitor"
Identifier "Generic Monitor"

#originals
# HorizSync 28.0 - 51.0
#VertRefresh 43.0 - 60.0

HorizSync 30-96
VertRefresh 50-160
Option "DPMS"
Modeline "800x600_75.00" 48.91 800 840 920 1040 600 601 604 627 -HSync +Vsync
EndSection

heres how i got that modeline (as i assume you used the same method)

dacks@dacks-box:~$ gtf 800 600 75

# 800x600 @ 75.00 Hz (GTF) hsync: 47.02 kHz; pclk: 48.91 MHz
Modeline "800x600_75.00" 48.91 800 840 920 1040 600 601 604 627 -HSync +Vsync

dacks@dacks-box:~$

Ye and afaik u have to prepare a modeline for each resolution@refreshrate you want to use. At least that's how it is working for me. Also, the first line becomes default.

ahh the sweet taste of victory
apparently my modeline names were not matching up with my mode settings in the screen section.
this fixed it. thanks all for your help in solving this mystery.
