Bug#758990: xorg: probe fails to detect screen size

[Piviul <piviul@riminilug.it>]

Hi all, I have to add that there is no way to change screen size: xrandr
-dpi do nothing, setting DisplaySize in section Monitor in xorg.conf
neither and do nothing too setting dpi Option in Device section.

Please there is a workaround to set the correct display size or dpi
using samsung syncmaster T260 monitor?

Thanks a lot
