In the XF86Config file look for (e.g.):

Section "Screen"
   Driver          "SVGA"
   Device          "Primary Card"
   Monitor         "Primary Monitor"
   DefaultColorDepth 32
   SubSection "Display"
      Depth        8
      Modes        "1280x1024" "1024x768" "800x600" "640x480" "320x240"
   EndSubSection            

The order of the modes is the way they come up. I.E. 1280x1024 is the
default.

Try using XF86Setup.  It has an option that allows you to pick the color
depth and resolution that X will start up in.

1. Changing default screen resolution for "xdm"

Hi,

I have been able to install and get xdm running.  My question now is:

How do I change the default screen resolution?

The default appears to be 640x480 and I would like it to default to 1024x768
resolution.

I have tried reordering the choices in the XF86Config file but it does seem to
help.

Any suggestions would be greatly appreciated!!!

Please e-mail suggestions to JSlater(at)Qualcomm(dot)com.

Thanks in advance for the help!
