ASUS Zenbook variable boot time?

Hardware Support

I have Zorin 18 installed on an ASUS Zenbook 14, and the time it takes from cold boot, through the Zorin icon, logo, and to the login screen can vary widly. Sometimes it's 20 seconds, occasionally a minute, and just now it wouldn't boot past the logo until a hard power cycle, at which point it booted in <20s.

Are there any logs I can check to see what takes what amount of time to boot, and what might be causing it to vary (or in this case fail)?

systemd-analyze

systemd-analyze blame

systemd-analyze critical-chain

Interesting, thanks - I guess these are only for the last boot, and won't tell me what made it hang 2 boots previously...

Yes, so it is.
You could take a look at the app logs.

These commands gave @Nourpon me once to find out problems with previous boots:
"

  1. List Previous Boots
    Use the following command to see a list of previous boot sessions:
journalctl --list-boots
  1. View Specific Boot Logs
    After identifying the boot ID from the list, you can view the logs for that specific boot by executing:
journalctl -b #

Replace # with the boot ID you want to investigate.

Are Secure Boot and Fast Boot in BIOS disabled? Is Your BIOS in UEFI or Legacy Mode? Do You have Window installed, too?

But when You have it again, You can use it after that and post it here.
