[Fixed] Fedora 39 keeps rebooting when left idle for a long time
[Fixed] Fedora 39 keeps rebooting when left idle for a long time
Edit: Fixed by this comment: https://lemm.ee/comment/8626267 Thanks!
Hi all, please help me figure out this weird issue I've been having. Any time I leave my laptop idle for a long time, when I come back to it, it's back to the log in screen as in the laptop rebooted.
I am not sure which logs I should be looking for to figure out the source of the problem.
Here's my system info:

Could also be going to sleep for power saving.
Ooh, I might actually be able to help here. Try disabling screen sleep in your power options and see if that fixes it. It took me a long time to narrow my issues down to that. I still don't know why it happens.
And definitely let me know if that fixes the issue for you. I'd love to know it's not just me and my laptop.
Seems to have fixed the issue, it didn't reboot overnight. Thanks!
I'd look if there's an updated BIOS version for your system, ACPI issues like that are usually a non-compliant subsytem in the firmware.
Thanks, I had screen sleep set to 10 minutes. Hibernation has been off since a long time. I will let you know by tomorrow if this fixed it.
Without sounding rude, are you sure it's at the login screen and not the unlock screen?
not rude. yeah it's a login screen as when I input my password all apps that I was using are closed, blank new session.
OK, thanks.
I guess it's worth confirming if it's been a logout or a reboot as well. If you open a terminal and type "uptime" does the time match when you booted up or after you left it alone for a while?
Check the output of:
dmesg -Tand have a look through:/var/log/messagesI would be focussing on errors, warnings and/or terms like "reboot, shutdown, logout, timeout, idle, etc." to try to narrow it down what is happening and when.
If it really has rebooted, it could be some graphics driver issue causing it to freeze up. I had stuff like that on Nvidia graphics back in the day. Linux will reboot itself after a while if it freezes.
I have had the same issue in the past.
It might come from going into hibernation. Since you have an nvidia card it's where the error is most likely.
Without more info this is a good best guess. However, Instead of the graphics card I would suspect an undersized swap space to support hibernation.
Yes, agreed with the other comment. Did you check uptime command ? In your system info it shows Uptime : 22 mins. In a terminal you can also type
uptimeorwIs it possible that you're on a different TTY? The login screen used in Fedora has some problems with using the correct TTY if you don't use auto-login. If this happens again, try cycling through them, maybe your old session is still there.
