Hi everybody,

I have a problem with the displaysize/DPI after upgrade to debian xorg 7.3+10.
The DisplaySize in xorg.conf is ignored. In Xorg.log I first find the lines

after xf86InitialConfiguration
(**) RADEON(0): Display dimensions: (305, 229) mm
(**) RADEON(0): DPI set to (133, 133)

which is taken from the DisplaySize directive of xorg.conf and is correct.
But later on almost at the end of the log:

(II) RADEON(0): Setting screen physical size to 423 x 317

which is the wrong size. xdpyinfo shows

screen #0:
  dimensions:    1600x1200 pixels (423x317 millimeters)
  resolution:    96x96 dots per inch

I tried also
Option          "IgnoreEDID"    "on"
and/or
Option          "NoDDC"

but neither of them has an effect.

Can any body help before I commit a bug report?

Best Regards

Pezhman
