How to Configure XFree86
 

My display is off to the right, how do I configure XFree86 to correct that?

How do I decode the settings in XF86Config-4, especially the modes and resolution.

Re: How to Configure XFree86
 

Is it way off to the right or only a little bit? If it's only a little off-center, you can easily correct this with the monitor controls (well, usually). If the horizontal display is way out of whack, then you might need to tweak your XFree86 config file.

Did Mandrake and/or X correctly find you video adapter type and monitor type? Or did you have to select something ``close''?

also, you may want to check if you have a program called "xvidtune" which may be what you are looking for.

\edit
note that on my Debian setup this program can be found either at:
/usr/X11R6/bin/xvidtune or /usr/bin/X11/xvidtune
(vs. /usr/bin, etc.)

Thanks guys!

I believe the settings are right for adapter and monitor. I use xf86cfg to select the right settings, XF86Config-4 is as below. I also have a different set of settings in XF86Config??
Which is X using?
Can I choose refresh rates.

I use xvidtune to center the display, should work well.

to make it permanent:
set it up correctly, and press "show" (this should be run from an xterm or the like). now a line like "1024x768" # # ..... is shown on the terminal.
add this line to your XF86Config-4 (XF86Config is used for XFree 3.3.x and older)

under "Monitor"
ModeLine "1024x768"....

...from your file:

the largest possible (ie. hardware/vid card capable) resolution is started w/ default depth (again if possible)

did I misunderstand the question?
