I have a dual boot system with Ubuntu 16.04 and Win 7 but I only use Ubuntu for many years now. Suddenly, for a couple of weeks now, Ubuntu sometimes gets stuck on logo screen during boot process when I power on my laptop. After one or two restarts (with Alt+Ctrl+Del) it boots normally. I don't know if that happens on windows also because I always boot on Ubuntu at first and then I try on Windows.

How can I figure out if the problem is an Ubuntu issue or a laptop issue ?

Update 1

In order to find the boot messages of my previous reboot, I ran the following commands to create the journal folder:

sudo mkdir -p /var/log/journal
sudo systemd-tmpfiles --create --prefix /var/log/journal

After that I set Storage=persistent in /etc/systemd/journald.conf and then:

systemctl restart systemd-journald   

Thus, I ran:

journalctl -b1

which displayed a log file of 2149 lines which on one hand is above the limitation of 30000 characters and on the other hand it contains much personal information. Can I run a more issue-oriented command like:

journal -b1 | grep <something> 

in order to identify the error ?

Update 2

Finally I figure out that my boot get stuck because of the following error:

A start job is running for Hold until boot process finishes up (Xmin Xs/no limit)

I found solutions from the following related topics:

Cannot boot system due to start job running for hold

16.04 - boot stops at "A start job is running for Hold until boot process finishes up(time/no limit)

https://www.rffuste.com/2016/10/01/ubuntu-16-04-a-start-job-is-running-for-hold-until-boot-finishes-up-error/

but neither worked for me.

Any ideas ?

  • Have you tried logging boot messages? – Aryo Adhi May 13 '18 at 12:33
  • In ubuntu 16.04 doesn't exist /etc/default/bootlogd file. I tried journalctl -b0 SYSLOG_PID=1 command but it displays only the last boot process which is successful. – Gpetr May 13 '18 at 15:12
  • Finally I found the error. During the boot process it raises the following: A start job is running for Hold until boot process finishes up (Xmin Xs/no limit). I 'll update my question. – Gpetr May 19 '18 at 11:06
