             Bug #: 50830
           Summary: GeForce 8500 GT Connectors Reversed
    Classification: Unclassified
           Product: xorg
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
        ReportedBy: kjwinchester-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org
         QAContact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org


I have noticed that the nouveau DRM kernel driver seems to get the
connectors reversed on my GeForce 8500 GT card.  My setup looks like:

8500GT----------VGA-----------Samsung 2043W (1680x1050)
          |______DVI_______LG L1920P (1280x1024)

but as far as the kernel is concerned, the Samsung monitor gets
detected via the DVI probing:

[    0.521009] [drm:drm_helper_probe_single_connector_modes],
[CONNECTOR:15:DVI-I-1] probed modes :
[    0.521015] [drm:drm_mode_debug_printmodeline], Modeline
21:"1680x1050" 60 119000 1680 1728 1760 1840 1050 1053 1059 1080 0x48
0x9

and the LG via the VGA probing:

[    0.551267] [drm:drm_helper_probe_single_connector_modes],
[CONNECTOR:17:VGA-1] probed modes :
[    0.551272] [drm:drm_mode_debug_printmodeline], Modeline
89:"1280x1024" 60 108000 1280 1328 1440 1688 1024 1025 1028 1066 0x48
0x5

I have used my xorg.conf configuration to re-reverse the monitor
definitions to get a working system, but should some quirk be added to
handle this particular card:

Are there any other details I can provide that could help?  Even if I
had to write the patch myself and test it, that would be fine by me
with a little advice.

Yes, your VBIOS has it backwards, so a quirk is probably needed.  Can you post
the "lspci -vn" output for your GPU.

Thanks.

I had to fudge the patch a bit because I applied it against mainline linux
rather than the nouveau tree, but it seems to work perfectly.  The new dmesg
shows the right monitors probed through the right connectors, and I was able to
switch my xorg configuration back to normal and everything still works.

Thanks alot!

Thanks for letting me know!  I've pushed this to nouveau git, it'll make its
way to Linus' tree in due time :)
