           Summary: Using RanrR radeonhd driver passes wrong resolution
                    information to applications
           Product: xorg
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)

         Component: Driver/radeonhd

Xorg.log file without a configuration file

If I configure the radeon driver to use RandR, some applications like GDM and
the GNOME panel don't occupy the full screen but a fraction of it.

Looking at the log file I see:

(II) RADEONHD(0): Output VGA_1 disconnected
(II) RADEONHD(0): Output TV_SVIDEO disconnected
(II) RADEONHD(0): Output DVI-D_1 connected
(II) RADEONHD(0): Output DVI-D_2 connected
(II) RADEONHD(0): Output DVI-D_1 using initial mode 1280x800
(II) RADEONHD(0): Output DVI-D_2 using initial mode 1680x1050

It's a RS690 as the log says.  It's integrated in the motherboard.  Physically
the motherboard has two display connectors, one VGA, one DVI.  The monitor is
connected to the DVI output.  The monitor resolution, as seen in the log file
is 1680x1050.

Problem: GDM behaves as if the display resolution was set to 1280x800. 
Furthermore, the output of xdpyinfo says the display resolution is in fact
1680x1050, but xrandr reports only up to 1280x800.  Initially the GNOME panels
are only 1280 pixels wide and the lower one is located at the "edge" of the 800
pixel tall display, but I can drag it to the lower edge of the monitor and it
will expand to occupy the full 1680 pixels.

If I disable RandR using the NoRandR option, everything behaves ok.

Is this a problem in the radeonhd driver or a problem in GNOME?

The problem is easy to reproduce for me, I can provide more information on
request.
