Public bug reported: Binary package hint: xserver-xorg-video-intel
The 13" MacBook Pro (8,1) has an integrated Intel 3000 video card. As of Ubuntu Natty Narwhal 64bit+mac Nightly 2011.04.16, whenever I attempt to connect an external display using the supplied VGA adapter, the external display is properly detected by vendor, resolution and refresh rate. However, the screen is black and it claims that there is no input source. I can drag windows into that region, but the display is just not showing anything. You can see this behavior clearly by disabling compiz (Ubuntu classic, no effects). When compiz is enabled, you get additional problems. As soon as the display is recognized, the primary screen goes black. The only way to restore the primary screen is to disconnect the adapter, switch to the virtual terminal and restart gdm (sudo service gdm restart). Clearly compiz is interfering with the monitor detection process. Here are two references to threads further describing this issue: http://permalink.gmane.org/gmane.comp.freedesktop.xorg.drivers.intel/3513 http://ubuntuforums.org/showthread.php?t=1720933 ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: xorg 1:7.6+4ubuntu3 ProcVersionSignature: Ubuntu 2.6.38-8.42-generic 2.6.38.2 Uname: Linux 2.6.38-8-generic x86_64 Architecture: amd64 CompizPlugins: [core,bailer,detection,composite,opengl,decor,mousepoll,vpswitch,regex,animation,snap,expo,move,compiztoolbox,place,grid,imgpng,gnomecompat,wall,ezoom,workarounds,staticswitcher,resize,fade,unitymtgrabhandles,scale,session,unityshell] CompositorRunning: None DRM.card0.DP.1: status: disconnected enabled: disabled dpms: Off modes: edid-base64: DRM.card0.DP.2: status: disconnected enabled: disabled dpms: Off modes: edid-base64: DRM.card0.DP.3: status: disconnected enabled: disabled dpms: Off modes: edid-base64: DRM.card0.HDMI.A.1: status: disconnected enabled: disabled dpms: Off modes: edid-base64: DRM.card0.HDMI.A.2: status: disconnected enabled: disabled dpms: Off modes: edid-base64: DRM.card0.HDMI.A.3: status: disconnected enabled: disabled dpms: Off modes: edid-base64: DRM.card0.LVDS.1: status: connected enabled: enabled dpms: On modes: 1280x800 edid-base64: AP///////wAGEMWcAAAAABwTAQOAHRJ4CgAAAAAAAAAAUFQAAAABAQEBAQEBAQEBAQEBAQEBUhwAj1AgLjAwIDYAHrMQAAAYAAAAAQAGECAAAAAAAAAAAAogAAAA/gBMUDEzM1dYMy1UTEE0AAAA/gBDb2xvciBMQ0QKICAgAB0= DRM.card0.VGA.1: status: disconnected enabled: disabled dpms: Off modes: edid-base64: Date: Sat Apr 16 15:25:14 2011 DistUpgraded: Fresh install DistroCodename: natty DistroVariant: ubuntu GdmLog2: GraphicsCard: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Apple Computer Inc.
