I missed the bit about xdpyinfo, never seen that program before.  I have:

screen #0:
  print screen:    no
  dimensions:    1440x900 pixels (373x231 millimeters)
  resolution:    98x99 dots per inch
  depths (7):    24, 1, 4, 8, 15, 16, 32
  root window id:    0x4c
  depth of root window:    24 planes
  number of colormaps:    minimum 1, maximum 1

The difference is in the "resolution" entry: Vince has 121x120, I have
98x99.  My text is all quite large, my icons larger.

What I really need to do is learn about X.  All of the docs I've found
have been for older versions or consist only of occult references to a
particular users' edge case.  It seems nobody's written a book about
xorg.  (Don't ask me to, I don't know enough to even write the
proposal! :-)

Does anyone have a recommendation for a decent user tutorial for X
troubleshooting?  I don't mean "run startx", I mean "this is the log
file and this is what the various entries mean" sort of
troubleshooting.

Thanks,
==ml
