Thread: Leap freezes for a few seconds every few minutes

  1. #1

    Default Leap freezes for a few seconds every few minutes

    Hello openSUSE gurus,

    I've been dealing with a frustrating problem that has made me want to avoid using my computer: this machine is constantly freezing every few minutes for up to 5-10s, and I'm not sure what is going on. During these 'freezes', the mouse is still operational and can be moved on the screen, but clicking on anything doesn't work; however, the click is sometimes registered and occurs the instant the freeze is finished. Typing normally during a freeze works due to the same behavior - whatever I type is 'saved' and appears on the screen after the the freeze is done. Youtube videos can freeze also, but the sound continues normally and catches up when the freeze is over. As you can see, this is apparent throughout the whole system.

    I'm on opensuse Leap 42.1, running GNOME desktop. I could be running as little as a terminal, a web-browser (chromium), and sometimes a text editor if I really want to get crazy, and this still occurs. CPU and RAM usage is minimal, so it's not like my machine is going into SWAP or something.

    I don't mess around with my machine too much, but I did have an internet issue a few months ago with the same machine (see the my post), where I adjusted some network options on my machine due to a wifi problem. I'm not sure if those changes caused this problem, I've been reluctantly dealing with this for a number of months now and haven't taken the time to submit an issue.

    Are there any checks that I can do to determine what the issue is here?

    You should probably start with overall system resources, like

    CPU make and model
    RAM physical, total
    Hard drive - Size, RPM and seek time

    If your overall system resources are very minimal like a relatively old CPU, 4GB RAM or less, or an older, slower hard drive with slow seek times, then you should either use less resources (turn off unnecessary, open fewer apps at once, etc) or change to a "lighter" Desktop than what you are using, in the openSUSE world XFCE is a good alternative to Gnome.

    If I need to switch over to XFCE, then so be it, but I've used Leap previously without issue. I think this freezing problem is caused by something else

    sounds like a graphic acceleration issue to me, do you have an extra graphic card or are you using intel's build in one, if you have an extra nvidia card you need bumblebee
    https://en.opensuse.org/SDB:NVIDIA_Bumblebee

    it could be a bad hdd sector or a bad ram chip, it could even be dust on the cooler, your issue is too vague.

    Not likely a GPU driver issue,
    I don't know that an i7 has ever been in an optimus.

    And, it looks like you have ample resources.

    Recommend you open and run top in a console continuously on your machine so you can monitor what is happening in real time.
    When your screen freezes, see what half dozen or so processes are running at the top. You can even try different versions of top (like htop), although you can customize what is displayed, it's convenient to just try a different app.

    At the moment I'm suspecting something like a cron job, perhaps indexing your hard drive in the middle of the day.
    It might also be a clue if this only happens for a few hours at the same time each day or all day.

    all ix cpu's have a build in gpu, being a high end cpu it's highly probable he has an external gpu, if not am optimus rig then in bios he should check and see what gpu is set as active, select the external and install propitiatory drivers

    Intel is the exception,
    The latest and current Intel architecture (i7) which first started appearing about 3 years ago (I think today is something like 4th generation i7) usually has one of the two highest end Intel HD GPUs, nothing lower has ever been included AFAIK.

    So, I don't think you'll ever see an alternate GPU built into an i7 system because it's already got the best Intel can offer at the time.

    Boot and run for some time in text-only mode. See whether freezes are there.

    I have seen these freezes too. They can last for up to a minute or so in my experience.
    They don't happen all the time, I can go a month without seeing one, then there will be another quite randomly.
    The strange thing is that when it happens there is very little activity on the CPUs or memory (that is able to be recorded), but intensive activity on the hard drive.
    This could imply swap activity, but I won't be running any heavy duty apps at the time.
