Do you mean that your X won't start because the monitor / video card info needs to be changes?

If yes,

Find the specs for your monitor Refresh Rate and Horizontal Sync (use either the manual that came with your monitor or the manufacturer's website to get accurate information).

You also need to know what driver to use for your card...go here and see which driver matches with your card.

Edit the file:

/etc/X11/XF86Config-4 <--If it is there

or

/etc/X11/XF86Config <--If XF86Config-4 doesn't exist

and change the values for:

HorizSync
VertRefresh

to the values you got from a valid source for your monitor ... this is critical ... your monitor or video card (or both) can fry if you set these wrong! Here is an example for my NEC Multisync E1100:

HorizSync 31.0 - 82.0
VertRefresh 55.0 - 120.0

Also, in the video card section, find the line:

Driver "xxxxx"

and change it to the driver (from the link above) that matches your video card. {If your video card is a fairly new NVIDIA (>FX 5200) or ATI Radeon (>9700) you may need to install proprietary drivers from the applicable website to get it to work at all.}

Save the file and see if X works...

In the XF86Config file, look for this section:

Section "Screen"

change the default color depth to 16 or 24 vice 8 ... here is mine as an example:

CODE

Section "Screen"
       Identifier "Screen0"
       Device     "Videocard0"
       Monitor    "Monitor0"
       DefaultDepth     24
       SubSection "Display"
               Depth     24
               Modes    "1024x768" "800x600" "640x480"
       EndSubSection
EndSection
