Lock up problem
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 😅
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 😓
I don't know enough about Linux to troubleshoot the problem effectively 😅
Sounds like a memory leak to me. To test my theory you could open a memory monitor on your first clean boot (from Terminal you could use the "top" tool). Sort by memory consumption in top. Then note what the largest consumers of RAM are. Check again after about 10 min, and then another 10 min later. Do you see a process that is increasing that you wouldn't expect to be?
I thought the same thing, but couldn't find anything new or unexpected in sysmon 😓
Sat at low cpu and gpu usage.
Run a memory test, I was having issues like this that turned out to be some RAM that passed self-tests but failed during certain kinds of writes.
Been running a memtest for two hours. Hopefully done soon 😅
Memtest just finished, everything is fine 😅
What does “journalctl -b -1 -e | less” say when you run it after a crash? Like the last 20 lines.
Also when it crashes can you get to a different tty by pressing ctrl-alt-F2 or is the system completely locked?
I will try these out and report back
Here's what I got from that command. Everything below the "Shutting down" command. Lookint through what it provided... there is a LOT in that search that I don't understand. It looks like it recorded it from last night (when I had not experienced the issue) instead of just now. ::: spoiler results
::: 😅 sorry if I grabbed too much
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 😓
Can't even shut down 😅
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
Haha, yup! Been running them for 2 hours already 😅
Just to close out this thread...
The diagnostics didn't reveal anything problematic.
I reinstalled fedora.
Problem is gone. If it returns, I'll post a reply here.
I an having a similar problem. Linux mint.
