Just some more information to get that thing down.

I've used the latest git and started without the external monitor attached and
Xorg -logverbose 7.

With RROutputOrder set to PANEL:

(II) RADEONHD(0): Output PANEL connected
(II) RADEONHD(0): Output VGA_1 disconnected
(II) RADEONHD(0): Output DVI-D_1 disconnected
(II) RADEONHD(0): Output PANEL using initial mode 1400x1050
(II) RADEONHD(0): RandR 1.2 support enabled
(==) RADEONHD(0): RGB weight 888
(==) RADEONHD(0): Default visual is TrueColor
(==) RADEONHD(0): Using gamma correction (1.0, 1.0, 1.0)
(II) RADEONHD(0): FUNCTION: RHDGetVirtualFromConfig
(II) RADEONHD(0): FUNCTION: DxFBValid: CRTC 1
(II) RADEONHD(0): FUNCTION: DxFBValid: CRTC 2
(II) RADEONHD(0): Using 1400x1400 Framebuffer with 1408 pitch
(II) RADEONHD(0): ScanoutBuffer at offset 0x00008000 (size = 0x00785000)
(**) RADEONHD(0): Display dimensions: (290, 210) mm
(**) RADEONHD(0): DPI set to (122, 169)

And in the second try without the RROutputOrder:
(II) RADEONHD(0): Output VGA_1 disconnected
(II) RADEONHD(0): Output PANEL connected
(II) RADEONHD(0): Output DVI-D_1 disconnected
(II) RADEONHD(0): Output PANEL using initial mode 1400x1050
(II) RADEONHD(0): RandR 1.2 support enabled
(==) RADEONHD(0): RGB weight 888
(==) RADEONHD(0): Default visual is TrueColor
(==) RADEONHD(0): Using gamma correction (1.0, 1.0, 1.0)
(II) RADEONHD(0): FUNCTION: RHDGetVirtualFromConfig
(II) RADEONHD(0): FUNCTION: DxFBValid: CRTC 1
(II) RADEONHD(0): FUNCTION: DxFBValid: CRTC 2
(II) RADEONHD(0): Using 1400x1400 Framebuffer with 1408 pitch
(II) RADEONHD(0): ScanoutBuffer at offset 0x00008000 (size = 0x00785000)
(==) RADEONHD(0): DPI set to (96, 96)


The strange difference is the dpi calculation:
With the RROutputOrder: DPI set to (122, 169)
Without: DPI set to (96, 96)

Shouldn't there be no difference when no additional screen is attached?

Thanks for help.
