    18.04.1 still freezes

    A 2002 build Dell laptop with 2 GB RAM and Lubuntu running and providing all the tools and features I need.
    I have run 17.10.1 for the last few months with the occasional freeze that leaves no trace in the logs.
    The problem seems to occur when the machine is busy, no obvious relationship with any particular process.
    The Lubuntu experience has been good and I waited for 18.04.1 as I have no interest in the 'bleeding edge' and a LTS installation seemed the best approach for me.

    But, a few hours after a totally clean install of 18.04.1 with all the defaults, a typical freeze.
    Had htop running in a terminal and Firefox playing a YouTube video.
    I was interested in the apparent low 'busyness' of this latest installation of Firefox.

    If the rate of freezes is no worse than before, I will persevere as I can get my work done and the Linux experience is enjoyable.

    But, it would be nice if the cause of the freezes could be identified, at least I might then be able to avoid the risk situations.
    Previous threads by me on the same subject produced no explanation, and numerous other threads hold no hope.

    Any hope of an explanation ?
    John.

    Are you monitoring temps? Have you run memtest? If it's not too much trouble, give more info like:
    Code:
    lspci
    lscpu
    sensors
    sudo dmidecode -t bios
    I need a new signature.

    my dell runs hot when watching videos and that may be the cause of the problem.
    if you can install (if it's not already there inxi) and run this command and post the output here.
    Code:
    inxi -Fxz

    Re: 18.04.1 still freezes

    Hi,
    Thanks for the suggestions.
    As noted in my first post, I had htop in view because the machine fan was very quiet while Firefox was running.

    My previous experience with an earlier version of Firefox on 17.10.1 was high fan noise, slow web browsing and extreme 'busyness' on htop.
    When I swapped to Flashpeak Slimjet, everything went quiet, browsing was normal and htop looked Ok.

    Code:
    john@Bluebox:~$ sensors
    dell_smm-virtual-0
    Adapter: Virtual device
    Processor Fan: 2714 RPM
    CPU:            +45.0°C

    Re: 18.04.1 still freezes

    Hello,

    I suspect that the freezes you are experiencing might be due to low memory. Indeed Lubuntu should consume no more that 300MB of memory, yet firefox can go really high depending on the number of the tabs you have open.

    Does this happen when you have a browser open, or is totally random? If there are some specific processes that cause that issue, then you might be able to narrow it down and identify the suspect.

    I would advice you to do the following: install chromium and falkon. Open exactly the same tabs using these browsers and then compare them with firefox. Pick up the browser that consumes the lowest memory. Work with it and then check anew if you experience the freezes you are mentioning. Just an idea so as to eliminate browsing.

    Regards!

    Re: 18.04.1 still freezes

    Claus,
    I have had freezes with just LibreOffice and LibreCad running, albeit with multiple drawings and documents open.
    I switched to SlimJet to avoid the 'busyness' of Firefox, yet still got the occasional freeze.

    But, running out of memory is a new line of investigation that I will follow, after the multiple cycles of memtest.
    While writing this, htop reports memory at 551M/1.96G, swap at 0k/1.72G and cpus at about 20%.

    John.

    Edit:
    Added GKrellM to the desktop so that I might see the status of the machine at the freeze.
    If I can remember to keep it on top of all the windows !

    Re: 18.04.1 still freezes

    Hello,

    it might not be memory the issue. I'm just informing you about this, since, having similar memory in one of my boxes, I had a freeze once (lubuntu), when I had many tabs open using chromium (maybe even 15 or so) and maybe other open programs as well. Firefox was prohibitive issue, since it required much more memory at that time (a month or so ago). Multiple tabs increase enormously the amount of memory consumption, so you could easily check that.
    The amount of memory you are reporting is normal. An easy check as well, since you remember more or less the programs in use while you noticed the freezing issue, is to open them again in multiple instances: usually cad programs require a lot of memory, so open them again and see how much memory is required per instance. Lubuntu, idle, requires extremely small amount of memory, yet with many programs open, things can change.

    Good luck,
    Regards!

    Re: 18.04.1 still freezes

    Recently had a freeze with one tab of the Slimjet browser open and scrolling in a simple page.

    The frozen display of GKrellM was cpus at 25%, memory at 25% and swap very low.
    The Krell configuration is 10 updates per second, so the display could be way too late to see the problem.

    I have since changed the Swappiness from 60 to 10.

    Ran Memtest86+ for 5 passes over 9.75 hrs without any fault reported.
    The test window showed test being applied to memory block 1024 to 2048 on my 2GB machine.
    I now propose to swap the two internal memory sticks and re-run the test.

    I don't run many applications, but none of them ever seem to suffer their own crash.
    So the problem could very well be confined to the OS or video drivers.

    John.

    Your BIOS is A33 but an A38 has been released. Have you considered updating?
