This is my first foray into Linux so I am not really sure what to do/where to look.

As the title says, after logging in to my user account, the system will hang on a black screen for approximately 30 seconds before finally getting to the desktop. I am assuming this is way to long, since I can get into windows in approximately 10 seconds from hitting the power button.

I am using a dual boot setup on an Acer Aspire A515-54g laptop on an SSD. The install is clean, Ubuntu has been installed and the automatic updates applied. Nothing else.

systemd-analyze blame shows:

systemd-analyze output:

Startup finished in 2.722s (firmware) + 1.049s (loader) + 1.803s (kernel) + 24.247s (userspace) = 29.821s

  • I don’t find 18.04 to be particularly fast to boot with gnome. I much prefer LXQt. Have a look here “askubuntu.com/questions/1166486/…“ Could be systemd is waiting for network connections.

  • Try "systemd-analyze critical-chain". That will show you which components are impacting total boot time. The components with the largest +nn.nn numbers are the ones worth looking at. My Acer Aspire E1-572 returns about 13.6 seconds in response to a simple systemd-analyze. That's a less capable laptop than yours but it is running Arch and LXQt. "systemd-analyze plot > file.svg gives a complete graphical representation.
