    Occasional Complete System Freze

    A few times now my wife's laptop (Ubuntu 20.04) has frozen.
    Screen freeze, keyboard unresponsive, can't change tty, even magic alt sysreq REISUB combination does nothing.
    The only way out is long press of the power button.
    She's always been running firefox at the time, but that's the only app she ever uses, so I doubt that means much.
    Normally the panels/bar (and clock) are hidden, but this time the time was displayed - 11:17:20
    Checking the log viewer for that time the only thing within a minute seems to be a cron authorisation

    11:17:01 cron: pam_unix(cron:session): session opened for user root by (uid=0)

    Then I can see no other entries until reboot at 11.33.

    Any help in figuring out what is going on would be much appreciated - hardware or software, and how to tell?
    How to investigate what the cron job was authorising?
    What else to look for next time it happens?

    Thanks

    Re: Occasional Complete System Freze

    I can't help you with cron jobs but I can help you with REISUB.

    Ubuntu does not ship with REISUB fully enabled.

    Here is a method to enable the process by editing a file:-

    Code:
    sudo nano /etc/sysctl.d/10-magic-sysrq.conf
    Then change the number in line 26 from 176 to 244 i.e. kernel.sysrq = 244

    I found the solution at this site https://digitalfortress.tech/debug/w...buntu-freezes/ and the information was in section 3.

    By the way, the last letter in the process B reboots your system, sometimes you may want to power off completely by substituting the B for an O

    Thanks for that. It might allow a more dignified exit come the next freeze.
    The question of how to go about investigating the cause remains.

    Re: Occasional Complete System Freze

    Common crashes are due to hw failures or out of memory conditions.
    And overview of the system would be helpful.

    inxi -Fxxz

    top, free, dmesg and journalctl should be helpful too.

    Thanks for taking an interest.

    Here's the output of inxi, top and free.

    Re: Occasional Complete System Freze

    In Firefox, disable all ad blockers and then enable this: uBlock. That may help., won't hurt.

    To me, my first guess would be memory chip failing. Make sure that laptop is getting air through the vents and that she is not holding on her lap or anything soft that can block the vents.

    Re: Occasional Complete System Freze

    The output for the monitoring commands needs to happen while the same programs are running as when the system freezes. Looks like the data above was run when the system wasn't doing anything. Where's the web browser in the process table? Really, we only need to see the top 10-15 processes AND only those when the system is busy.

    On a CPU like that, I wouldn't use Gnome3. I'd run XFCE or no DE at all to keep the system as fast as possible. Gnome3 is a bloated DE, especially for a CPU with about 2000 passmarks.

    I think 1G of swap is not sufficient for any Ubuntu desktop. I always setup 4.1G swap these days regardless of RAM. Less and a browser with lots of tabs will crash the system without enough "slowing system" feedback before hand. Any more and it is wasting storage. The point of swap is to let the user "feel" the system getting slower as RAM is exhausted. It is still up to the user to close programs to prevent a crash. SSDs are so much faster than spinning HDDs, so we humans need a little more time to notice the issue as it happens, hence the need for a larger, 4.1G swap. I had a few laptops with 1500-3000 passmarks, 2G or 4G of RAM, running a lite Ubuntu version (Ubuntu-Mate) that would crash about once a month. They had the default, whatever-the-installer-created amount of swap. Usually, the systems would get really, really, really, slow for about 2 minutes before becoming unresponsive. Initially, I just gave each time to resolve the issue, which they never did. After 20 minutes, I'd have to power them off. Then I increased the swap to 4.1G. Never had that problem again, because it gave me more time to "feel" the system become slower. Usually, I'd be running FF and Thunderbird, plus a bunch of xterms. Closing FF would be an inconvenience - lots of tabs still to be read, but closing thunderbird was an easy choice and usually freed about 1G of RAM.

    Just some things to consider.

    When looking through the system log files, look for errors and warnings. Failing hardware usually will get something into the logs. The only HW faults that many not get into system logs would be failing storage. For that there is SMART - use smartctl to run a test, then wait until the test completes (2min - 4 hours) and use smartclt to ask for the test results. It is a long shot, but not hard.

    Thanks. For at least one freeze ublock origin was the only addon.

    In any case for the last one the only tab open was bbc.co.uk - which has no ads - though I've noticed it does occasionally have some moderately cpu and RAM eating content.

    This netbook has no fans and no vents - normal power consumption is 3.8 watts, and it never feels warm. I will figure out how to get cpu temp displayed continuously though. I suspect that will be far more of a challenge with gnome than it was with kde.

    Re: Occasional Complete System Freze

    Thanks - lots to consider there. I'll work through it - I've jotted some initial thoughts below.

    The output for the monitoring commands needs to happen while the same programs are running as when the system freezes. Looks like the data above was run when the system wasn't doing anything. Where's the web browser in the process table? Really, we only need to see the top 10-15 processes AND only those when the system is busy.

    inxi just relates to fixed properties as far as I know, journalctl does cover the freeze period, so I guess you are referring to top and free? I don't how I would get top or free to autostart, log an iteration every so often to a text file, and delete all but the last few to keep space used reasonable. I'll ponder it!
    By the way firefox was running for top - it goes by the process name Mainthread I think for some reason

    On a CPU like that, I wouldn't use Gnome3. I'd run XFCE or no DE at all to keep the system as fast as possible. Gnome3 is a bloated DE, especially for a CPU with about 2000 passmarks.

    I agree - though 20.04 does run really pretty well. More significantly it's for my wife, and it is, I think, the most attractive and user friendly Ubuntu interface for a novice (and frankly disinterested) user. When it doesn't freeze she's delighted with it! 5 year support is another plus - reduces the change frequency. Her only OS experience before this was a chromebook - which was simplicity itself and totally bombproof, but is now AUE. May yet have to buy another though.
    I might try her with Xubuntu or Lubuntu if I do a reinstall.

    This is something I think I might possibly be able to do something about!

    I'll give that a shot too.
