dual screen dpi bug in radon or Xorg?

[Bernd Schubert]

Hi all,

xdpyinfo reports:

screen #0:
  dimensions:    3520x1200 pixels (410x310 millimeters)
  resolution:    218x98 dots per inch
  depths (7):    24, 1, 4, 8, 15, 16, 32


Well, I have two screens... So the dimension in pixels is right, but in 
millimeters it is only the dimension of one screen...

Therefore the resolution is completely wrong, which just causes me some pain 
with xmgrace....


Thanks,
Bernd
