           Summary: radeon: xdpyinfo returns wrong screen size
           Product: xorg
           Version: 7.4
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: estellnb at gmail.com
         QAContact: xorg-team at lists.x.org


same as Bug 20409, just for radeon.:

> xdpyinfo | egrep "resolution|dimension"
  dimensions:    3840x1200 pixels (555x350 millimeters)
  resolution:    176x87 dots per inch
This is very nasty since programs like KWord which rely on xdpyinfo do not work
at all.

> xrandr -q|egrep "Screen| connected"
Screen 0: minimum 320 x 200, current 3840 x 1200, maximum 3840 x 1200
DVI-D_1 connected 1920x1200+1920+0 550mm x 344mm
PANEL connected 1920x1200+0+0 508mm x 317mm

> grep DisplaySize /etc/X11/xorg.conf
        DisplaySize  370 230
        DisplaySize  555 350
PANEL in deed: 370mm x 230mm

xdpyinfo should perhaps return the dpi value for the primary screen featuring
555x350mm:
3.4 x 3.4 dpmm =  87 x 87 dpi  (555 350)
5.1 x 5.2 dpmm = 132 x 133 dpi (370 230)

Consequently I would expect the following output:
> xdpyinfo | egrep "resolution"
  resolution:    87x87 dots per inch
and not:
  resolution:    176x87 dots per inch
