           Summary: nouveau reports DPI correctly in Xorg.0.log, but value
                    reported by X incorrect
           Product: xorg
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: minor
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
        ReportedBy: bjt23-HmMyXyqgL2CVc3sceRu5cw@public.gmane.org
         QAContact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org


A bit odd:

$ grep -E 'DPI|dimensions' /var/log/Xorg.0.log
(**) NOUVEAU(0): Display dimensions: (290, 180) mm
(**) NOUVEAU(0): DPI set to (112, 112)

290mm x 180mm and 112x112 DPI are indeed correct (1280x800, 13.3" widescreen),
however:

$ xdpyinfo | grep -E 'dimensions|resolution'
  dimensions:    1280x800 pixels (338x211 millimeters)
  resolution:    96x96 dots per inch

X appears to be getting bogus data, which screws up font sizing.

I'm on a MacBook Pro 13" with GeForce 9400M (NVac).  Using nouveau-drm from the
kernel tree with git rev eeec3a1ecd703d3a32fe223274d2a77686030d78 (built out of
tree for kernel 2.6.32-gentoo-r2), and xf86-video-nouveau git rev
2630a1553d560ce2c7391bc103d4a543f7d3d0da.

If there's any more data or info I can provide, please let me know.
