Thanks for respond!

Sorry, writing about "111x117" I meant "dpi", not just "pixels". I was away
from the OS and can not remembered the values exactly. Here is more accurate
info:

NVIDIA driver version 185.18.36

$ xdpyinfo:

name of display:    :0.0
version number:    11.0
vendor string:    The X.Org Foundation
vendor release number:    10604000
X.Org version: 1.6.4
[...]
screen #0:
  dimensions:    1366x768 pixels (313x171 millimeters)
  resolution:    111x114 dots per inch
  depths (7):    24, 1, 4, 8, 15, 16, 32

My Ubuntu version is 9.10

$ uname -ra
Linux localhost 2.6.31-16-generic #53-Ubuntu SMP Tue Dec 8 04:01:29 UTC 2009
i686 GNU/Linux

I think a correct string in xorg.conf may help a lot.
