    slow boot

    Hello,
    I've just installed kubuntu 18.10 on my old Macbook (MacBook "Core 2 Duo" 2.4 13" (White-08)) and everything is almost ok but the boot time.
    It is _very_ long, about 3 minutes. Something is wrong but I do not understand what.
    Can anybody help me identifying (and hopefully solving...) this problem?
    Here (https://pastebin.com/FhJn4zg8) is the output of the dmesg command just after the boot process.

    Thank you so much!

    Bye,

    Open a konsole and run systemd-analyze and systemd-analyze blame to get a better idea of what's going on.
    If you think Education is expensive, try ignorance.

    The difference between genius and stupidity is genius has limits.

            Are you booting with "quiet splash"?

            If so, or you don't know what that is, I suggest editing /etc/default/grub to remove those words, so that it has
            Code:
            GRUB_CMDLINE_LINUX_DEFAULT=""
            GRUB_CMDLINE_LINUX=""
            (To edit that file you can use kate; kate will ask for privilege when you save it.)
            Then, run sudo update-grub. Without "quiet splash" one sees what's happening during the boot, though it normally flashes past unreadably, especially with systemd. Even if there aren't errors, you might see it stall at something which would give a clue.
            Regards, John Little
