           Summary: Dualhead on mobility 9200: 2nd display resolution
           Product: xorg
           Version: 6.8.1
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Driver/Radeon
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: nanophase at gmail.com


I succeeded to extend the desktop to my external TFT, but it's resolution is
being set to 640x480. Once I set the MetaModes option, the external tft remains
blank. Comment that line out, 640 again. It seems to me as a driver issue. If I
set Metamodes so that both displays use the same 1280x1024, it's a clone mode
but with a viewport of 1280x800 as it seems, I can scroll the screen on both
displays (laptop and external tft). Hoped I would have just black bars around on
the bigger screen..
So please advise, or point me to a tutorial or a sample config for such a
configuration. I already reported bugs in the radeon doc since following it not
only didn't help in this situation, but had mistakes making the X server not
even start. So I think that's not really up to date.

Thank you
attaching my config..
