System freezes randomly while browsing

Hi!

I’m encountering random freezes while using the computer. It often happens while I’m browsing the web on Firefox, but I’m pretty sure it already happened while on another software - not entirely sure though.
The screen becomes unresponsive for a couple of seconds and then I can resume my activity just fine. It’s quite annoying as it can happen multiple time in a day (in an hour, but I don’t use this computer so much).

Here is the result of inxi --admin --verbosity=7 --filter --width:

I can provide additional informations if needed. What should I look at / research?
Thank you very much for any help provided.

Have a great day.

Classic troubleshoot here involves monitoring your system.
Given your hardware, probable bottlenecks would be:

  • disk read/write (may involve CPU)
  • CPU
  • GPU

You could also monitor system logs, but i doubt you’d find anything relevant…


Does it happen only on battery? Only when plugged in? Both?

Thanks for your reply.
This is a pretty fresh install for me so I’m kind of (re)discovering the linux world and I’m trying to find / learn good ways to monitor and find clues as to what bottlenecks are involved.
It does happen plugged in and on battery. I’m using the power saver mode, could it be interfering in any meaningful way? Do you have pointers to documentation that could be of some help?

Thanks again.

I got that around one of the freezes.

JS ERROR: Error: Expected an object of type ClutterActor for argument 'sibling' but got type undefined
                                               _syncStacking@resource:///org/gnome/shell/ui/workspaceAnimation.js:80:18 

and a lot of errors around Touchégg.

Error connecting to Touchégg daemon: Could not connect: Connection refused

I will dive a bit into that to see if it has something to do with it.

Consider updating BIOS to latest version - BIOS Update - ThinkPad X270 - Lenovo Support

Thanks! I did it by following a guide (can I link it for reference to future readers?).
We’ll see if it does the trick.

Hi again! I did update the BIOS but I’m still getting these small freezes every few minutes.
I am going to dig a bit more into logs to try to find out and will update the thread if I find something.
Thank you for your answers.

I’m still getting them, watched for odd temperatures, CPU / RAM usage and didn’t find anything. No luck in the logs either. It could come from the SSD, I’m trying to gather information on this, will update if this gets resolved.

I believe that when it happens, everything is still going on “under the hood”, only the image is frozen. For example, I can still click on the screen, and the sound is still on.
