    Fresh 18.04 64Bit Install - Slower Than Normal Boot Time?

    Hi,

    My previous motherboard died, so I bought a new different motherboard and installed it.
    I then did a fresh install of Kubuntu 18.04 64Bit LTS.
    Boot times seem slower than what I remember?

    System specs:
    - 750watt PSU
    - Gigabyte GA-970A-DS3P (rev. 2.0) Motherboard
    - AMD FX 3.5GHz 8-Core CPU
    - 32GB DDR3 RAM Memory
    - nVidia GeForce GTX 970 4GB GDDR5 GPU
    - Western Digital 1TB Hard Disk Drive

    Is there a log file somewhere where I can see why the OS is booting so slowly?
    Thanks!

    Jesse

    I had the same problem. The solution is here: https://askubuntu.com/questions/1030...n-ubuntu-18-04

      Hi,

      Which of those fixed the slow boot issue?
      I tried "noresume" boot perimeter but there was no improvement.
      Thanks!

        Well, since I can't attach an image file...
        1. Edit the file /etc/default/grub file so that the string noresume is included in the GRUB_CMDLINE_LINUX_DEFAULT line, for example:
        GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noresume"

        • Run this command to update GRUB:
          sudo update-grub

        • Reboot the computer


        My desktop load time went from about 60 seconds to about 10 seconds.

        I see you're using a HDD. You have my sympathies.

          Thanks for the reply, but I tried "noresume" already with no improvement in boot time.
          Any other ideas?
          Thanks!

            My boot time a is also abysmal, and has become more so over the past few LTS releases (the only ones I do). So since I boot once a day, ijust do something else until the computer decides it's ready.

            I recently bought a couple of SSDs, at least one of those will become my new boot drive. I suspect.hope for reduced boot time.

              I've got a couple computers here all running Kubuntu 18.04 64Bit LTS.
              (none except this one have the long boot time)

              I suspect the new motherboard I am running: Gigabyte GA-970A-DS3P (rev. 2.0).
              There is a problem with USB/NIC on this board with *ubuntu 18.04 which is solved by doing the following:
              1. Enable "iommu" in the BIOS and save and reboot
              2. In terminal, type: "sudo nano /etc/default/grub"
              3. Add: "iommu=soft" to end of: GRUB_CMDLINE_LINUX "..." and save changes
              4. Run "sudo update-grub" in terminal
              5. Reboot
              6. In BIOS, disable "iommu", save and reboot

              Hopefully someone knows how to fix this?
              Thanks!
