How to read start-up logs

What the title basically says. Is there a way to read the startup logs of my OS (running openSUSE tumbleweed)? There are some errors while starting my system but can't read them since they are scrolling too fast.

Have you tried a search engine?

Edit: I apologize, that was mean and pointless. 😬

This gives a detailed breakdown: https://www.suse.com/c/system-logs-understand-linux-system/
- Back to the old days of forum discourse? If you have nothing of value to add it's best to stay silent.
  
  Yeah you're right. I'm sorry. 🙈
- Have you tried putting vinegar on your eggs?
  
  Have you? Not being a dick here, it's legit delicious!

i dont know suse, but try "dmesg" or look at /var/log/messages (or maybe /var/log/syslog)... just poke around the log directory.
dmesg

You may need to run it as root
- Thank you.
journalctl, but I don't know the exact flags to provide. I think -k or -b?
- -b gets all logs for the current boot, -k shows kernel messages (what dmesg gives).
The dmesg command via either sudo or root can show a lot of that output. If your system did not have rsyslog or the syslog-ng packages installed any more then you'd only have systemd journal but you can, depending on your Linux distribution, install these logging applications. Back in the days when Linux users would not always use a graphical display manager, you could actually use shift and page up and page down to scroll through the kernel boot up messages.
- Thank you.
