I’m experiencing frequent freezes on my Ubuntu 24.04 LTS system, even when there are no applications open. Has anyone else encountered this issue, and what potential solutions or troubleshooting steps can you recommend?

Hey everyone!

I’ve been having a really annoying issue with my Ubuntu 24.04 LTS system lately. It keeps freezing up on me, and it’s driving me insane! The weird part is that it happens even when I don’t have any applications running. Just sitting there, minding my own business, and out of nowhere—bam! Everything just locks up. No mouse movement, no keyboard input. Nothing. It’s like my computer just decides it’s time for a nap or something.

I’ve tried a few basic troubleshooting steps. First, I made sure everything is fully updated using the Software Updater. I figured maybe an outdated package could be causing the hiccups, but that didn’t seem to change anything. I also had a go at checking for any hung processes or resource-hogging tasks in the System Monitor, but there didn’t seem to be anything out of the ordinary when the freezes happen. It’s just so odd!

I even ran some diagnostics to check the hardware, and everything seems fine. No overheating issues, the HDD is in good shape, and the RAM is functioning normally. I’ve tried checking the logs in /var/log/syslog and /var/log/kern.log to see if there are any errors reported around the time the freezes occur, but I’m not sure what I’m looking for. So, I’m wondering if anyone else has encountered this strange freezing issue?

I know it’s kind of vague, and I’m really hoping someone out there has faced something similar and can share their experiences. Are there any specific logs I should look at that might give a clue to what’s going on? Or any driver issues I should check?

I’d love to hear what you all have tried that might help resolve this. It’s super frustrating because I can’t even figure out if it’s a software bug or if my hardware is playing up. Any tips or tricks would be amazing! Thanks so much in advance; I’m desperate for some solutions!

    1. Sounds like you’re having a really tough time with those freezes! I’ve had a similar experience on my system too, and it can be super frustrating. Here are a few things you might want to try or check out:

      • Check for Swap Usage: Sometimes if your RAM is maxed out, the system can freeze. You can check this by running free -h in the terminal to see if you’re using swap space.
      • Look into Kernel Logs: It’s great that you already checked /var/log/syslog and /var/log/kern.log. Look specifically for error messages or anything that seems weird right before the freeze. You can use grep to filter keywords like error or fail.
      • Graphics Drivers: If you have a dedicated graphics card, make sure the drivers are up to date. Sometimes generic drivers can lead to system instability. You can check and update them using Software & Updates > Additional Drivers.
      • Check Hardware Compatibility: If you’ve recently updated your system, it might be worth checking whether there are any known issues with Ubuntu 24.04 LTS and your specific hardware components.
      • Boot in Recovery Mode: Try rebooting your system and selecting recovery mode from the GRUB menu. This can help you determine if the problem is software-related.
      • Run System Diagnostics: You mentioned the hardware checks are fine, but running tools like memtest86+ can help rule out any RAM issues that might not show in regular checks.

      If all else fails, you could consider reaching out on Ubuntu forums with your log snippets and hardware details. The community is often really helpful, and someone might have a clue that’s specific to your setup!

      Hope this helps, and good luck getting it sorted out!

    2. Freezing issues in Ubuntu, especially when they occur without any applications running, can be quite perplexing. Since you’ve ruled out overheating and checked the health of your HDD and RAM, it might be beneficial to investigate the potential for driver issues. Specifically, if you’re using proprietary drivers for your graphics card, consider reverting to the open-source drivers or ensuring that your installed drivers are up-to-date. You can manage this through the “Software & Updates” application under the “Additional Drivers” tab. Additionally, checking your GPU’s configuration through terminal commands could provide insights. Use lspci to list hardware and glxinfo | grep "OpenGL version" to see your graphics driver version.

      Logs can be a treasure trove of information. While you’ve already checked /var/log/syslog and /var/log/kern.log, also consider looking into /var/log/Xorg.0.log if you suspect display-related issues, as it logs events related to the X server. The command dmesg in the terminal can also display kernel-related messages, which might help identify any hardware or driver problems. Furthermore, if you haven’t done so already, you can check for any ‘watchdog’ timer messages, as they can sometimes indicate freezes. Lastly, setting up a temporary live environment with a different Ubuntu version or desktop environment could help you determine if the problem persists across configurations, tightening your focus on either hardware or software as the source of the issue.
