Hi, I'm using a VGA adapter to connect my MacBook to a Thomson LCD TV. Sometimes when I plugin the cable in my laptop the system freezes and I have to manually reboot it. I'm using Mac Os X 10.5.7 (but I had the same problem with other releases) and the firmware of the adapter is already updated. Do you know if there is something I can do about it?

MacBook 13,3", Mac OS X (10.5.7)

    Are you connecting the VGA plug to the mini DisplayPort adapter while the latter is currently plugged into the MacBook? How about connecting the VGA cable to the mini DisplayPort first and _then_ trying to plug the mini DisplayPort adapter into the MacBook. The latter might work better for hot-plug detection.

    Thanks, but I'm already pluging the adapter to the MacBook after having connected the VGA cable with the adapter.

    I have the exact same problem. The crash occurs at random moments for me. Not necessarly during the connection. I use an DELL LCD panel.

    My vga adapter was firmware upgraded lately and I am running osx 10.5.7

    I have been having this problem for some time now. I'm going to perform a complete re-install of OS X this week and see if its an OS problem. My adapter worked fine originally, well I say fine, I still have the flashing monitor issues but all of a sudden it causes my system to completely hang now resulting in a grey screen.

    I will re-install and let you all know.

    Same problem here. When I plug in my secondary monitor (an HP w2207), OSX occasionally freezes and I have to hard-reboot it.
    However, it seems that only the graphics driver crashes, since I can still login to my machine via SSH.

    I have the same problem with my macbook when I plug it into my TV, it only happens sometimes, usually when I haven't restarted in a while. I have to manually turn off and turn on again, and then it works.

    Are there any solutions?

    Me too. I have had this problem for the last 9 months since I bought the Unibody MacBook. Every time I connect my external display I get a system freeze for about a minute (cannot move the mouse pointer etc.). Then about one time in 10 it completely crashes the machine and I have to forcibly restart it. All my software is up to date including the display port adapter.
    I can't believe Apple haven't got their act together and fixed this one in all this time. C'mon Apple, do something about it, given the number of people it seems to be affecting.

    Hi,

    +1 : same problem

    Screen : NEC LCD22WV
    Context : plug mini-displayport to VGA adapter (I always plug LCD VGA cable to the adapter, and then adapter to my macbook)
    System log during system crash (seems to be graphic crash only):
    Sep 15 14:13:02 x kernel[0]: PM notification cancel (pid 1936, Safari)
    Sep 15 14:13:02 x kernel[0]: IOPMrootDomain: idle cancel
    Sep 15 14:13:03 x kernel[0]: PM notification cancel (pid 1936, Safari)

    Sep 15 14:21:42 x com.apple.usbmuxd[15]: MuxClearPipeStall Can't clear pipe stall 1. Error: 0xe00002ed

    And then the normal reboot messages :

    Sep 15 14:23:59 localhost com.apple.launchctl.System[2]: fsck_hfs: Volume is journaled. No checking performed.
    Sep 15 14:23:59 localhost com.apple.launchctl.System[2]: fsck_hfs: Use the -f option to force checking.

    Sep 15 14:24:01 localhost com.apple.launchctl.System[2]: launchctl: Please convert the following to launchd: /etc/mach_init.d/pilotfish.plist
    ........


    This problem seems to be very common.
    No surprising : many users use mini display port, at work or at home, in order to use a large LCD screen.

    Last message is from one month now : is there any news, reporter bug number, or (I'm optimistic) a solution ?

    Thanks to any people replying.
    And
    Thanks to Apple to fix it very soon, as it's not acceptable to crash when you only plug a LCD display ...

    Smokey,

    I had a similar problem connecting to my TV via HDMI.

    I believe I had to adjust the screen settings for the external screen. You might need to use "recommended settings" for your external display.

    Good luck,
