    Doesn't Dual Core work on 64 Intrepid?

    I've been using Ubuntu for a long time but I've only switched to 64 recently.
    I've noticed that the system monitor only lists my CPU as a whole instead of two cores.

    This is the output I get when running
    Code:
    sudo cat /proc/cpuinfo
    Code:
    processor	: 0
    vendor_id	: GenuineIntel
    cpu family	: 6

    clflush size	: 64

    power management:
    Is this normal because I'm using 64 or is there anything I can do to make the dual cores work?

    By the way the device I'm working on is an Asus laptop (M51VA-AS024C).

    There was not another section after that one that started with"processor :1"?

    Nope, that's the whole thing. But this is the output from an Intrepid 32 live cd that I'm posting from right now.

    Unless I've misunderstood something (which is possible) it is a dual core processor: http://ark.intel.com/cpu.aspx?groupID=35562
    Please correct me if I'm wrong.

    Thanks in advance.

    Yes the live cd confirms that OK no of cores 2, But how its only showing 1 core is a bit baffling?

    To make things more fun (read annoying) I've burned and tested a 64 live cd and it also reported two cores.
    That made me think that it might be a kernel update that screwed this but booting with the same kernel used on the cd didn't change anything.

    what kernel are you running?

    please post the output of:

    Code:
    uname -a

    Linux Zeus 2.6.27-11-generic #1 SMP Thu Jan 29 19:28:32 UTC 2009 x86_64 GNU/Linux
    The one I tried switching to was 2.26.27-7.
