    Default Multi-Monitor + DDD + Radeon = Xorg crash

    So this is a bit odd..

    I just installed DDD via Synaptic on my laptop for a little debugging that I need to do. Each time that I have tried running DDD, X has crashed shortly after the DDD logo was displayed. After some trial and error, I discovered that this only happens when I have a second monitor plugged into the HDMI port on my laptop, it functions as expected with only one monitor (LVDS). I'll test for this same crash when a VGA monitor is plugged in as soon as find a spare cable..

    This may be a bug in DDD, but I suspect it is in the graphics driver stack instead. Does anyone here have any ideas?

    Chipset: M76 (HD2600)
    Distro: Ubuntu 11.04
    Kernel: Stock - 2.6.38-10-generic x86_64
    libdrm: Xorg edgers - 2.4.26+git20110604.6dd804c5-0ubuntu0sarvatt~natty
    xserver: Xorg edgers - 1.10.1+git20110526.a8721393-0ubuntu0sarvatt~natty
    ddx: Xorg edgers - 6.14.99+git20110613.41eb1fbb-0ubuntu0sarvatt~natty
    mesa: Xorg edgers - 7.11.0+git20110614.7d488ade-0ubuntu0sarvatt~natty

    The Xorg log file only mentions 'ddxSigGiveUp: Closing log' with no other apparent errors.
