    Fair enough - but when you've only got an 11" laptop and old eyes display space is at a premium!

    Extend your display space by using Virtual Workspaces.
    I use a docklet in Docky for switching.

    Would that help? My problem is that when the system freezes no input works - so process information displayed in a space not visible at the time of the freeze will remain forever invisible.

    You can dump the GKrellM output at intervals to refer to when you resume normal working.

    I that functionality built-in, or would it need to be done by scripting?

    Re: Occasional Complete System Freze

    Options are documented here.

    https://wiki.gentoo.org/wiki/GKrellM

    If you install Synaptic Package Manager and search gkrell you see a full list of optional plugins.


    There is also a daemon (without GUI) which runs in background for remote monitoring.

    See gkrellm (gui) vs. gkrellmd (daemon).


    This script takes a snapshot

    https://nmap.org/nsedoc/scripts/gkrellm-info.html

    This could be run as a cronjob.

    [P.S.] In GKrellM configuration GUI (right click on popup window) each plugin parameter can trigger an Alert command so you can run commands if say temperature level is exceeded.

    Thanks for that. It would be quite a learning exercise for me, but in the current situation I'm not exactly plagued by distractions.

    Re: Occasional Complete System Freze

    Having suggested the above I'm not sure if this will detect cause of your freeze. You could try other experiments such as creating a fresh logon account (guest) to see if freezes still occur. Then there are extensions in browsers to disable. There is also hardware acceleration .. and so the list of possibilities/theories grows. A systematic process of elimination is needed. When last I encountered freezes on an old laptop I followed lots of ideas such as removing memory cards and cleaning board edges with a clean rubber then carefully replacing.


    [P.S.] Throwing into the ring another idea.
    Install Stacer from here.
    https://github.com/oguzhaninan/Stacer

    sudo add-apt-repository <add repository path here .. pasting it here creates this! ppaguzhaninan/stacer - >
    sudo apt-get update
    sudo apt-get install stacer -y

    Then look at the Stacer Resources dashboard to monitor resource peaks.

    It might offer some clues.

    Re: Occasional Complete System Freze

    I agree that diagnosing/remedying this might be a slow process. The freeze has only been happening about once a month, so opportunities to test theories are pretty limited too.

    I've tried stacer before, but found then that it was the biggest consumer of cpu on the system. Maybe it's improved.

    I have tested storage, I'm about to run a RAM test, and I have panel displays of cpu load, RAM, swap, all temperatures and battery voltage.

    Hopefully I might spot something between those and the logs come the next freeze to give me a clue to follow.

    This is a low energy cpu. It's not Bay Trail, but I have been wondering if cpu idle.max cstate might be an issue.

    Currently it's 9.
    I'm a bit reluctant to play with it, since battery life was one of the drivers for getting the machine.

    One final shot .. install petit to try to make sense out of accumulated log files up to the point of freeze.
    Another log search tool is glogg.
