How to run live log on second screen during application freeze/crash

Hi, I have an application more specific a game that crashes my whole system right after start (total freeze, with frozen screen and after a few minutes the system reboots). I would like to debug this in some way, so I would like to display some system messages or logs on my second screen, that way I hope to catch something what causes the crash.
What command would you or could I run on a console on the second screen to maybe catch the reason for the crash? Btw. It is probably Nvidia driver related.

@oliver_gtze Hi run journalctl -f to follow the log. Do you have another system you could ssh from, then can watch that way…

Ok I will try that, thank you
