Freezes KDE desktop after some hours of work



  • Strange, but Vivaldi freezes complete desktop after some hours of work, perhaps related to previous watched videos.

    Vivaldi 1.10 Stable
    Debian 8.8 x64
    8 GB RAM
    KDE 4.14
    Intel GPU Xeon E3-1200

    I could only switch to tty1 and restart OS with Ctrl+Alt-Del.

    May be there is a memory leak in Vivaldi 1.10 Stable? I read so much about it.

    Any hints what i could do?



  • @Gwen-Dragon
    I don't have any idea about the freeze.

    Because it's not locked your entire system; you could check for clues from.

    • $HOME/.xsession-errors. If we're lucky, recent X events will be logged there.
    • Any recent logs in /var/log. Same reason above.
    • $> dmesg | tail and or dmesg -k | tail. If you use current systemd probably need sudo or run as root.

    You could use Ctrl+Alt+BackSpace to terminate X session. IIRC, KDE/Plasma has option for it in its Control Panel somewhere. So you don't need to restart your system.



  • Thanks for some hints where to look at when X server or kdm freezes.

    Today i reinstalled my Linux, i report back if the problem is gone or not.

    Correct.

    Those pics are for my Tower's Maui, whose Plasma5 basically comes from KDE Neon. My Lappy now instead has openSUSE Tumbleweed [with which i am enjoying a new-found slow-burn love, & once i solve a few remaining issues i shall seriously consider also migrating Tower to OSS TW -- what a distro!!], whose System Settings menu layout is slightly different but still close enough that the pics remain ~valid... i intuit that probably any distro's Plasma5 spin will probably more or less follow the same layout.

    @Gwen-Dragon -- oh gahhhh, i apologise, i just realised that you're on KDE4 not Plasma5, silly me... but from vague memory i think the KDE4 System Settings layout is not so hugely different that the pics might still have some relevance...? And to your primary problem, fyi i don't think i can recall any system lockups i've had that i associated with Vivaldi [but then, even though Stable is always installed, i use it only occasionally, whereas i'm in V-SS pretty much every waking minute].

    @Gwen-Dragon How badly did your desktop freeze? When you switched to a TTY, were you able to kill the Vivaldi processes to see if that would free up system resources or release locks?

    If you're suspecting a memory leak, commands like top, vmstat -s, or even cat /proc/meminfo will help to confirm that.

    Hopefully it's not the X server itself locking up. Ctrl-Alt-Backspace will only work if your X server is still able to process keyboard input.

    I'm not sure what else to suggest until we can get more information about the nature of the lockups.



  • Mouse and apps were not accessible, KDE shortcuts failed. :(

    But i was able to switch to tty1 or other text logins.

    @Gwen-Dragon That's not good... at least you can still gather some stats and try to kill processes selectively from the command line. :-|



  • The only make sense info related to KDE 4 + Chromium/GChrome freeze:
    https://bugs.kde.org/show_bug.cgi?id=338999.

    QT4 issue.

    On last post, there's a link to duplicate bug report with same version @Gwen-Dragon's KDE.

    @dLeon Anything's possible but this (to me) sounds like something that just started happening. The Chromium team have been making some significant changes to the GPU stack and it's still a work-in-progress...

    @Gwen-Dragon Was your GPU blacklisted by the Chromium team and did you override the blacklist in vivaldi://flags?

    No, the GPU was not blacklisted.
