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)
but neither worked for me.
Any ideas ?
