    Problem:
    I seem to be having a great time with version 5 with all of the new features and power that it offers. I am however having a small issue. I currently run a 2009 dual quad core Nehalem Mac Pro with 12 GBs of RAM. I use 3 24" Apple Cinema Displays, and 2 Dell 18.5 Inch LCDs all connected.

    The problem I have is specifically with Linux 3d Acceleration, (Mint and Ubuntu). When I enable 3d Acceleration everything works great until I move the Linux VM to any display other than the main display. When I do the vm screen goes black. If I resize it I see for a split second that it the video is vertically flipped upside down, and then it immediately goes black again.

    If I drag it back to the main display it and quickly resize it everything is fine again.If I disable 3D support and reboot the linux vm, it works just fine when I drag it to a secondary display.

    Shutdown VM.

    Configure VM->Hardware->Video for more memory and try again.

    I have been having the exact same problem, I have 3 24 inch monitors and obuntu does work on the main screen enabling 3d but if I change it to a another screen changes stops working. The whole windows goes upside down the only way to fix it it's by not using the 3d, but takes all the fun from obuntu.

    I have exactly the same problem. 3 monitors and with ubuntu 9,10 I can not turn 3D acceleration on when I move the VM to my 2nd monitor.
    The second and third monitor are connected to a GeForce 7300 GT and the main monitor is connected to a Geforce 8800 GT.
    When I use Linux Mint and I use full screen view, set to use all monitors, I can turn the 3D acceleration on but I have to turn the fancy 3D options off in Linux Mint or the 2 monitors on my 7300 turn white.
