Lock up problem (lemmy.world)

Hi guys, been having a problem for a week now in fedora 43.

After half an hour of light use, my kde keyboard starts crashing at regular intervals, the taskbar is unresponsive, and the shutdown greeter will crash if i try to restart or shut down. I have to power cycle the system to turn it off, not the best.

Looking for anyone also experiencing the problem has not yielded any hits, so I'm posting here ๐Ÿ˜…

Thus far i have tried: -Restarting -Disabling Firefox video decoding (closest fix i could find in searches) -Rolling back to my previous Friday backups

The issue persists ๐Ÿ˜“

I don't know enough about Linux to troubleshoot the problem effectively ๐Ÿ˜…

The command needs to be run after you crash. It's showing the logs of the last time you boot (That's the "-b -1") which is why you're seeing yesterday's log.

I don't see anything crazy in this output.

You can change the options to trawl the logs if you like. type in "man journalctl" and you'll get a man page entry explaining what each of the options and how to use them.

    Well, it's not a hard crash. I lose functionality on my taskbar, and can't run any programs ๐Ÿ˜“

    Can't even shut down ๐Ÿ˜…

    When it happens can you swap to a different tty by pressing CTRL-ALT-F2 after things stop responding? If you get a terminal with a login screen then that means your desktop environment is hanging, not your computer.

    Nothing happens. I thought i might have had the wrong hotkeys and had to double check

    Then I would check the ram to make sure it's ok. Download memtest86+ load it on a thumbdrive and boot from that. Then run the memtests. It will tell you if your memory modules are fucked or not.

    The tests may take some time to run so go grab a beer while you wait.

    Memtest just finished. Everything is fine

    My next test would be trying to a live installation in order to see if it's hardware related or software.

    Boot into a live cd (I would use one that is the same distro as you already have) and do what you normally do. See if the machine locks up. If it doesn't then you've probably got some broken setting or program crashing your machine. If it does crash then some other hardware is causing the issue. You'd have to start taking out each piece of hardware out of the system to see if your crash is still there or not.
