             Bug #: 54044
           Summary: Xorg crashes on dual screen setup
    Classification: Unclassified
           Product: xorg
           Version: 7.6 (2010.12)
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: estellnb at elstel.org
         QAContact: xorg-team at lists.x.org


If I boot with my old setup (see attached xorg.conf) then Xorg crashes on
startup. That setup was still working with 1.7.7-14. Now with 7.6_1.12.3-1.2.3
I get a backtrace like attached. I have removed everything but the dual screen
setup from the xorg.conf (see Xorg.1.log, xorg-*-1-.conf) and Xorg is still
crashing which indicates that the dual screen setup may be at stake. 
  Fortunately it is not the dual screenery itself that makes Xorg crash. I can
boot in single screen mode without xorg.conf and then activate the second
screen via xrandr. This is a bit unhandy since I will have to configure KDE for
the second screen on every new boot by hand (i.e. plasma panel & icons) but
there is a way to get Xorg well up and running!
  Please have a look!
