Problem Description:

Hello,

I’m using Ubuntu 24.04 (via a dual-boot).

I’m experiencing an issue where after some use, everything freezes. All times I had to do a hard reset.

I’ve attached logs of journalctl when this has happened. (Apologies for the length, I copied the events surrounding any red-error text during the minute of the freeze.)

  • First time: laptop was idle at the time, I just had it on and was not doing anything, I had Firefox and PyCharm open. A faint screen flicker, then it froze.

  • Second time: Within the hour of the first time, I was using the same applications.

Tried to investigate, added line ‘i915.enable_psr=0’ to grub-config and updated grub / reboot

  • Third time: Same applications open, I just copied some files to a USB (logs will mention my USB) and it froze.

Then switched from Wayland to Xorg

  • More time has passed since last freeze. April 7th: Everything froze and the youtube video playing in a browser tab looped the last few seconds over and over.

  • Next day: occurred when watching a video on Twitch (via Firefox) and tried to lower video resolution. (Same last-few-seconds-of-video-looping behaviour.) Same day within 2 hours, freezes when pasting a few paragraphs of text. REISUB does not work.

I’m using an external usb-keyboard and bluetooth-connected mouse (if it’s worth noting).

The logs may give details about my device / environment but let me know what further info I can give to help!

I’ve been using Ubuntu for years on a previous machine (including use of 24.04) with the same keyboard/mouse, and have never had a locking issue like this. I wonder if there’s something with my new machine that’s conflicting.

What I’ve Tried:

As per above, tried tweaking the grub-config. I read the following:

I have these different things I can try next but I’m a bit confused on what is happening, why, and how whatever solution I try next might help.

Much appreciated for any help! :slightly_smiling_face:

Has your keyboard always been connected when freezes occurred? If so can you try without or use another keyboard (at least it won’t do any harm)?

I once had freezes on a desktop system presumably caused by a faulty keyboard. After changing the keyboard I encountered no more freezes.

Thanks for the suggestion!

I used my laptop for 5-10mins without the external mouse and keyboard plugged in and triggered the freeze watching a Twitch video, fullscreen, max resolution. Screen flickered, froze, last few seconds of audio kept looping.

I updated my linked journal file with today’s output - AI is deciphering it as a GPU fault and is suggesting downgrading the kernel to the last LTS version (it looks like I should consider 6.8 according to the kernel LTS releases listed here?).

Just did some more reading and here points out many users had a more severe glitching issue with 6.8 - I say more severe because mine didn’t trigger like theirs. That Medium article highlights the 6.8 issues were fixed in 6.11.

Extra info:

Forgot to say initially I did a memtest and had a successful pass.

Found some infos at Archlinux - Intel graphics - don’t know if these apply.

Maybe section low power Intel CPU is more appropriate.

I shall try enable_dc=0 as per that link.

I also came across this where that is a suggestion too (I couldn’t conclude if it was the same issue as mine but sharing if it helps anyone).

Thanks so much for the quick replies! :slightly_smiling_face:

Have you tried adding nomodeset to the kernal parameters at boot?

Not yet, as per the links at the end of my post, I did see that was a potential next step. Thanks for highlighting that to me though!

I haven’t had a freeze since my last comment but I’ll have to give it more time to see if that last tweak did the trick.
