    Re: my bootchart and long time!!

    It's always helpful if you describe your computer when you ask this kind of question.

    Is it a laptop? Laptops usually have slower hard drives than desktops. Are you running Kubuntu? Seventy-five seconds to boot Kubuntu on a computer which is a few years old, is pretty reasonable.

    Re: my bootchart and long time

    Your bootchart shows IO Waits and disk utilization at 100%, so it looks like you have a slow disk. How full is the disk? Any SMART errors?

    Code:
    df -h
    sudo smartctl -a /dev/sda
    You are also running Landscape, which is a network monitor. Do you need Landscape on this machine?

    Re: my bootchart and long time

    Your disk is not full. You are running a Seagate 7200 rpm Barracuda, which is a speedy fish.

    You have possibly a lot of corrected errors on this drive:

    195 Hardware_ECC_Recovered 0x001a 048 028 000 Old_age Always - 177788232

    If I read this correctly (and you will have to do some research on this particular drive), you are at 48% from 100% (brand new) of corrected errors.

    You have some uncorrectable errors on the drive (UNC) and an ATA error (which is the SATA Input/output layer). Change or reseat the cables. Clean the dust out of the electronics of the drive, and start backing up your data. It could be a simple as a loose cable, or a drive that is about to fail.
