A week or two ago, My ubuntu laptop (ASUS X556U) has started to experience a 10-30 second delay before reaching the first purple screen (GRUB loaded). I think this is happening since a package update in the last weeks.
The output of
systemd-analyze time is
Startup finished in 5.633s (firmware) + 2.423s (loader) + 3.604s (kernel) + 15.727s (userspace) = 27.388s graphical.target reached after 15.350s in userspace
so the loading time of Linux are good/fast enough for me.
How can I regain my usual boot time¿?
