From when I reboot my Ubuntu 18.04 until I see the login screen it takes about 2 minutes. It seems that booting the kernel is not the problem. The following is the result of running systemd-analyze time.
Startup finished in 2.898s (kernel) + 10.392s (userspace) = 13.291s graphical.target reached after 10.386s in userspace
My guess is that this has something to do with gdm. Here is a few lines of my /var/log/syslog right after a reboot.

The most obvious delay here is before It prints Inserted module 'lp' which is about 50 sec. I'd appreciate if someone could help me with this.
