           Summary: laptop with radeon igp320 works with LCD fails with
                    external monitor/projector
           Product: xorg
           Version: 6.7.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Driver/Radeon
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: erichey2 at comcast.net


I have an hp ze4630us laptop with radeon igp320 card running linux 2.6.7-rc2,
glibc 2.3.3.20040420 with nptl enabled, and xorg-x11-6.7.0. The laptop dual
boots with WinXP. X works normally when using only the LCD screen. When I cable
an external monitor or projector to the laptop (directly, no port replicator),
both the LCD and the external monitor work in character mode, but as soon as X
starts only the LCD continues to work. The monitor reports continually recycling
horizontal and vertical settings (no relationship to what is specified in
xorg.conf) but no screen image appears. If using a projector, a "no input"
signal is given and blue screen appears. If I boot WinXP, the external
monitor/projector work normally. I've tried using variable and fixed
horizontal/vertical settings including vertical 60hz (this is what WinXP uses).
I've tried omitting the extra radeon options. The external monitor/projector
will work with the vga driver but the image is too large to be useful. The LCD
screen works well with almost any horizontal/vertical setting.

I don't detect anything different in the X log when operating with or without
the external monitor. 

Here is my xorg.conf
