Ubuntu Crashing: Trying to Determing Cause

ae flag
Jesse C.

Last night Ubuntu effectively crashed on me. I was running the following applications:

  • Firefox
  • VSCodum
  • Citrix Browser
  • Zoom
  • Signal
  • Terminal

Specifics:

  • Three monitor setup; during the event, I couldn't move my mouse from the left screen to the middle and right screen; it was as if it were "stuck" at the border.
  • Apps were non responsive, but then I could occasionally hear others in the zoom call-re the zoom call, I wouldn't hear someone for a while, and then they would speed up really fast-newly assembled PC (two days ago)
    • very, very careful during assembly
    • 8 cores
    • 32 GB ram
    • liquid cooling-MSI bios shoes all hardware is functioning as designed. CPU temps are constantly low.
  • fully upgraded (sudo apt upgrade)
  • full updated (sudo apt update)
  • no details in /var/crash

This has only happened ONE time. I've been watching my system resources carefully and haven't seen a heavy strain on CPU or memory.

/var/log/syslog had this information. I've tried to summarize it:

Welcome to AskUbuntu! Could you [edit] your question to include the version of Ubuntu you're running and perhaps some specifics about which hardware is in your machine? This may make it easier for someone to identify a possible issue.

Since the logs mention "nouveau", I would guess this error has something to do with GPU and the nouveau video driver? Considering that the nouveau driver is an open-source and reverse engineered driver, it shouldn't be all that surprising if some issues pop up once in a while.

I've seen similar on my laptop with an AMD CPU/GPU. The common factor is Zoom. It's a resource pig, and will happily cause weird GPU issues and hang the entire desktop. Seen it many times. Not a lot you can do about it.

*nods* zoom had been banned where I work for the same reason.

I'd try installing the proprietary NVIDIA drivers and see if that clears things up. It looks like the Nouveau NVIDIA driver is throwing a tantrum. And if you're using an NVIDIA 3060 card, you probably want the additional features the proprietary driver comes with - your card is essentially crippled with the Nouveau driver. You should be able to find the good drivers for your card by opening "Software & Updates" in the application menu, then clicking "Additional Drivers".

Okay, I'd like to pick y'all's brain a little bit more while you're here. I tried installing the latest video driver for my GEForce 3060. It worked, with the exception of it being unable to detect my other two monitors. So, I reverted back to nouveau. Does anyone else have suggestions?

@ArrayBolt3 Sorry, I didn't see your comment until I had already posted mine. Maybe you can provide some guidance. Please read my most recent post. I was sure to run sudo apt update and sudo apt upgrade AFTER installing the Nvidia proprietary driver. Still wouldn't detect my other monitors.

@JesseC. Try searching for "Display" in the application menu. This should pull up a button that lets you configure your displays. See if you need to enable or otherwise move around the other two displays.

@ArrayBolt3 Okay, I just got home. I believe I checked that before, but perhaps I missed something. I'm following some steps found here as well. I'll let you know what happens: https://askubuntu.com/questions/1431915/second-monitor-not-detected-in-ubuntu-22-04

Okay, I believe this may've resolved the issue. This is assuming that the open-source Nouveau display driver was the primary cause of the problem of course.

Initially, I attempted to use the NVIDIA open kernel driver (530) at the top of list this, but despite my best efforts - disabling secure boot, cycling the monitors, ensuring all was updated - my two side monitors were not being detected.

But then after attempting the other open kernel NVIDIA driver version, I decided that I'd shoot from the hip and try the 530 metapackage - it worked! All three of my monitors are working, and I was able to keep secure boot enabled.

It remains to be seen if Zoom will be a significant chugger in the future, but as of right now memory and CPU are showing very low usage. Thanks everyone!

Warm Regards, Jesse

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.
