Ubuntu 20.04 LTS freezes randomly - Suspecting Nvidia

My Ubuntu 20.04.3 LTS freezes randomly, sometimes after 20 mins, sometimes after several hours.

This means I can't move the mouse nor do anything with my keyboard. If sound is playing it repeats in ~2 sec loop. No key-combination does anything; just a hard reboot with the PC power switch gets me to restart.

According to this post I have collected some Information, though I am a newbie to this things and can't make real sense of any of this:

Sorry if any of this is unrelated. I am suspecting my GPU is not working properly, because my programs run much more slowly than on my dual-boot Windows on the same system. Also, I get some libcudart and libcublas errors when running some of my programs, and these seem to be related to my GPU as far as I know?

Any suggestions on how to troubleshoot or resolve this issue?

EDIT: As requested I ran the commands dmesg,cat /var/log/syslog ,journalctl and this are the results:

github-files

cat ...

journalctl

(I couldn't paste all this code in here due to body limitation, so I put it on github)

You need to run a simple command called `dmesg` and post it all.

@Tyþë-Ø I did, as you suggested. I can't make any sense of the outcome though.

at least try `cat /var/log/syslog` and `journalctl`, this last one is long but necessary.

eli44

6/9/23, 3:54 PM

@Tyþë-Ø have done so. I added 2 new files to the github repo - for ```journalctl``` I added the last 8000 lines, because thats what got displayed in my terminal.. Am I looking for anything specific here? Do I need a certain time interval or does this help already? Thanks already!

To avoid confusion create separeted files for `cat /car/log/syslog` and `journalctl`. Where are those files?

eli44

@Tyþë-Ø I separated into different files, sorry about the confusion

Did you installed fake Spotify? Installed new theme or something special related to Desktop Enviroment, yours is GNOME right? How your internet adapter is operating, and when was the last time your computer crashed unexpectedly?

my Spotify should be legit.. it works fine and I installed it on purpose. I have GNOME, yes. Except I didn't install anything. I am using dual boot with win10 btw. The last time my computer crashed was I think 4 days ago, when I left it alone to run a long program. My internet is working totally fine..

I'll be giving the possible solutions:

Reinstall Gnome:

sudo apt-get update 
sudo apt-get install --reinstall systemd gnome-settings-daemon gnome-settings-daemon-common

I'll be updating...

okay, I have done so. Thank you so much for putting that work into my problem! I will get back to you if I have news, or if it seems to have worked

Alright, don't forget to mark as right answer if it worked.

so far, I haven't had any freezes (: hoping it will stay that way. Thanks for your help!

Based in your log errors this solve big part of the issue, if you still have problems open a new question.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
