    On all systemd systems, all the system's logs are aggregated in "the journal."

    Although one could read the MAN pages for journalctl, I recommend the digitalocean article

    https://www.digitalocean.com/communi...e-systemd-logs

    I'd recommend a combination of the following commands
    - Invoke a previous boot (the session that crashed)
    - the last entries, however many entries you wish, similar to tail

    I haven't checked the following command, but should work to display the last 100 entries of the previous bootlog
    Code:
    journalctl -b -1 -n 100
    There are other ways you can extract entries by specifying error levels, specific processes, systemd services, etc as described in the article.

    Hi,

    There is a problem using: "journalctl -b -1 -n 100" in konsole:
    it truncates the information on the right?

    I am using KDE, but I don't see a log viewer app in Start menu?
    Any ideas?
    Thanks!

    Try with the konsole window maximized first.

    Or better, switch to a virtual terminal (ctrl-alt-f2), login, and execute the command from there.

    Hi,

    Came home to a frozen desktop again.
    I hard reset and booted into the OS and ran the suggested command in Konsole.

    Any ideas?
    Thanks!

    Hi,

    Just did a DuckDuckGo search and found this:
    https://github.com/kotelnik/plasma-a...itor/issues/41

    Is there something wrong with plasma-applet-thermal-monitor?
    Let me know, this is a mission-critical system so I need it to not freeze crash...

    That widget hasn't been updated for a while...

    There is reference to the error message you're seeing here: https://github.com/kotelnik/plasma-a...itor/issues/41

    ... but I don't know if fixing that will cure your freeze, could just be coincidental. It may be worth looking further back in the journal for any other errors...

    Hi,

    I disabled the temperature KDE Plasma widget.
    If it freeze crashes again, I will post new Konsole output.
    Hopefully we can fix this, thanks!
