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¿?
I experienced a similar problem on my Lenovo X220 some weeks ago.
In my case, the problem was the default GRUB_TIMEOUT, which makes the system wait for 10 seconds before loading grub. You can check this answer for more info. I managed to regain the usual boot speed by lowering GRUB_TIMEOUT to 1 second.
To achieve that, edit Grub's configuration file /etc/default/grub, and change the value of GRUB_TIMEOUT around line 8 and set it to 1:
sudo nano /etc/default/grubGRUB_TIMEOUT=10 and change it to GRUB_TIMEOUT=1sudo update-grubThen you should be enjoying a fast boot again.
