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

[JeZ-l-Lee]

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.

[JeZ-l-Lee]

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.

[JeZ-l-Lee]

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!
