FAIL msg. on boot of the PC

Postby 1byte » 2017-12-10 17:41

I am trying to establish what is it that failed on boot, but when I switch to console: Ctrl + Alt + F1
I can only see msg. that are on the screen:

Starting Avahi mDNS/DNS-SD Stack
Starting Network Manager
[ OK ] Started System Logging Service
[ OK ] Started Login Service
.....................................
[ OK ] Started Update UTMP about System Runlevel Changes


Debian GNU/Linux 9 MyLaptop tty1

MyLaptop login:

So when I log in and try Shift + PageUp nothing works and I can NOT scroll to the message that appeared early on in the process of booting up ...

When looking at "sudo dmesg" there is nothing indication there "in red" that there is a problem with something ...


Is there any way to check what process was it that FAILED early on during the boot process?

it's not necessarily in red, and it usually contains keywords like "fail(ed)" or error, sometimes also warning.

Nothing indicating FAIL in dmesg ..

Is there any way to view "ALL" the messages (below is example)that scroll past the screen on startup,
to establish what has failed?

Starting Avahi mDNS/DNS-SD Stack
Starting Network Manager
[ OK ] Started System Logging Service
[ OK ] Started Login Service

looks like systemd messages, so
Code: Select all
journalctl -b
should do it.
