Computer freezes randomly

Zorinhendrik · May 1, 2025, 7:08am

Hello dear friends, my computer freezes every now and then and I can't do anything.
The mouse doesn't move anymore
The explorer doesn't work
The browser doesn't work
The sound stutters
The only thing I can do is press the keys ctrl + alt + F4 to get a terminal in which I then give the command: reboot.

My system: Desktop computer
RAM = 64GB
Processor = Intel Xeon CPU E5-2690 v2 @ 3.00GHz x 20
Graphics = Nvidia GA106 Geforce RTX 3060
Total disk capacity = 10.0 TB
OS = Zorin OS 17.3 Core
Type OS system = 64-bit
Window system = X11

After restarting the computer works fine

Hi, I experienced this the other day and I only have 16 Gb RAM. Must check the Logs. Have you checked your event logs?

Open a terminal and enter:

less /var/log/syslog

or use the GUI Logs.

Zorinhendrik · May 1, 2025, 8:24am

Hi Swarfendor437,
I looked at the logs but it's all in English, I don't understand anything.
I also don't know the hour when the computer froze this morning.
As for the logs they are very long, it's full of data.

This is a log from GUI Logs

I see a lot of references to Virtualbox.
I'm going to remove that from the software now

swarfendor437 · May 1, 2025, 10:50am

If you have any VM's be sure to back them up. You could install the .deb package of Virtual Box 7 from the official site. Personally I only use virt-manager these days, and you can import .vhd:s createdin VirtualBox.

Ponce-De-Leon · May 1, 2025, 1:55pm

What Nvidia Driver are You using? And hwo are Resolution and Refresh Rate set up? Is Fractional Scaling active?

Zorinhendrik · May 1, 2025, 3:51pm

The nvidia driver 550
One monitor 31" resolution = 2560 x 1440 (16:9)
Three other monitors 24" resolution = 1920 x 1200 (16:10)
All four monitors refresh rate = 59,95 Hz
Fractional scale is off (not active)

Ponce-De-Leon · May 1, 2025, 5:40pm

You could try a different Nvidia Driver (the 570 or an older one like the 535 for Example). To change the Driver, first uninstall the current one with:

sudo apt purge nvidia*

After that install a different one with:

sudo apt install nvidia-driver-[Version-Number] nvidia-dkms-[Version-Number]

Replace [Version-Number] with the Driver Version Number like 550 or 535.

Another Thing: Ypu have installed VirtualBox from the Repos, aren't You? You could try instead the Version from the Developer:

Pay Attention to take the Version for Ubuntu 22.04.

Zorinhendrik · May 2, 2025, 9:34am

Thank you very much.
In the meantime I have now started using the Nvidia driver 570 and that seems to be fine now. So far I have no problems with the computer freezing.
I will now see for a few days whether it continues to work so well.

Zorinhendrik · May 4, 2025, 4:18am

Hello, I'm back.
Last night I fell asleep at my desk and when I woke up in the middle of the night my whole computer was frozen again.
I turned it off and now I started it again (06:00 am) and searched for a log but didn't find what I wanted to find.
I do have a log of the start-up.

I could not help but notice network manager issue. Found this:

Ubuntu 22.04 Network Manager Issue

If your computer is freezing when NetworkManager is involved, especially during a stop-start transaction, it might be due to a recent update or a misconfiguration. Some users have experienced issues after updating to Debian 12.4 with the .15 Linux kernel, where NetworkManager stops working and can cause the system to freeze.

To resolve this issue, you can try the following steps:

Check NetworkManager Status : Open a terminal and run systemctl status NetworkManager to check the status of the NetworkManager service.
Update and Upgrade : Run sudo apt update followed by sudo apt upgrade to ensure your system is up-to-date.
Revert to an Older Kernel : If the issue persists, you can try booting with an older kernel version. You can select an older kernel version from the GRUB menu during boot.
Check for Known Bugs : Visit the Debian bug tracker or relevant forums to check if the issue is known and if there are any proposed fixes.
Disable NetworkManager : If you don't need NetworkManager, you can disable it permanently by purging the package network-manager . However, be aware that this might remove essential components like gnome-control-center if you are using GNOME.
Reinstall NetworkManager : If the service is not running, you can reinstall NetworkManager using sudo apt install network-manager and then restart it with sudo systemctl restart NetworkManager .

If these steps do not resolve the issue, consider seeking further assistance from the Debian or Ubuntu community forums, as the problem might be specific to your hardware or a particular configuration.

AI-generated answer. Please verify critical facts.

Until this morning the computer froze again.

Have you tried upgrading/downgrading the kernel?

Zorinhendrik · May 12, 2025, 8:34am

No, not yet. This problem has been around for several months from 2024 to now.
In the meantime, the kernel has already been upgraded with an update.
But the problem keeps coming back.

swarfendor437 · May 12, 2025, 11:06am

I noticed you have snap and flatpak present in that output. Using Brave A.I. search engine via mojeek I found:

" Snap and Flatpak Freezes in Ubuntu 22.04

Snap and Flatpak applications can indeed be responsible for freezes in Ubuntu 22.04. Users have reported issues with snaps freezing, particularly after upgrading to Ubuntu 22.04, which can affect applications like Chromium and Firefox. These issues may stem from problems with AppArmor profiles or resource management within the sandboxed environments of snap and flatpak applications. For instance, AppArmor profiles in enforce mode can sometimes block necessary operations, leading to application freezes. Additionally, the sandboxed nature of snaps and flatpaks can sometimes cause compatibility issues or performance problems, especially if hardware acceleration or other system resources are not properly managed.

To address these issues, users have suggested switching to native .deb packages for applications like Firefox, which can sometimes resolve freezing problems.6 However, it is important to note that Ubuntu recommends using the snap store for many applications, including Firefox, starting with Ubuntu 22.04.

If you are experiencing freezes with snap applications, you might consider troubleshooting steps such as checking AppArmor logs, ensuring proper hardware acceleration settings, or switching to a native package if the issue persists.

AI-generated answer. Please verify critical facts.

There are indeed too many errors in the logs and I can't fix them all.
That's why I'm going to download Zorin OS 17.3 Core and do a fresh install so I start from scratch.
This seems to me to be the best solution.
We are going to end this topic and mark it as solved even though there is no real solution.

Ponce-De-Leon · May 13, 2025, 12:59pm

You could write here if a fresh Install helps. And don't forget to check the Checksum of the ISO.

Zorinhendrik · May 24, 2025, 9:39am

I have now reinstalled Zorin OS 17.3 Core but the problem remains.
Now I have found that gnome-control-center does not work when it is frozen.
I get the following error:
gnome-control-center;6172 GTK-critical 11;12;56,670;gtk_style_context_add_provider_for_screen;assertion'GDK_IS_screen failed

GTK-warning; cannot open display
