           Summary: xf86-video-ati / radeon 6.7.194 breaks mode detection
                    when docked (regression: works in 6.7.192)
           Product: xorg
           Version: 7.3
          Platform: x86 (IA32)
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: high
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: sofar at foo-projects.org
         QAContact: xorg-team at lists.x.org


When docked, the 6.7.194 driver enables the wrong mode for the panel when the
lid is closed at startup. the driver enables mode 1400x1050 on the external
panel, while the panel supports maximum of 1280x1024. xrandr lists the correct
modes at all times.

This worked fine with xf86-video-ati 6.7.192

The laptop is a lenovo t43 with 1400x1050 screen, when docked it is connected
to a 1280x1024 HP1740 17". This setup always worked fine until now throughout
xorg 6.8 -> 7.3, except for the last update of the ati/radeon driver.
