Thread: desktop when I boot it is fast and responsive, after one day staying on is slow and laggy

  1. #1

    Default desktop when I boot it is fast and responsive, after one day staying on is slow and laggy

    my pc desktop: CPU (Processor):Intel Core i5-7400 4x3.00GHz 7th Kaby Lake, Mainboard:B250M MSI Pro-VDH (7A70-003R), Video Card (VGA Card) onBoard Graphic, System Memory (RAM):8GB Kingston DDR4-2400, SSD:240GB Western Digital WD Green M.2
    running leap 42.3 with KDE when I boot it is fast and responsive, after one day staying on and with no operations by a user it becames slow and laggy, mouse is slow, selection is slow ecc, only reboot solve, and after reboot it start again to be responsive. I think 8Gb is ok, could it be the SSD managing by leap42.3??
    I can I solve this problem??
    many thanks, :-) ciao

    and have you looked at cpu usage and memory allocation?

    not that familiar with top but at the instant plasmashell looks to be high consumer. check any rouge widgets installed you have installed. [ps there used to be a bug in plasmashell whereby any animation in task bar would slow system - e.g. copy file animation] but this has been fixed ages ago though leap i suppose is on old version.

    Do you use modesetting driver for graphics? I have slowdowns after some time using it on my Broadwell. Slowdowns dissapear after update to latest Xorg/Mesa.

    I've read some bug reports about plasmashell exhibiting this behavior in some other scenarios too: when a background slideshow changes wallpaper, and with two monitors (I think when you switch monitors or something like that).

    If the slideshow wallpaper is the culprit, which is quite likely, you can apply a patch to "/usr/share/plasma/wallpapers/org.kde.slideshow/contents/ui/main.qml" as outlined in this bug report:

    it seems that the slideshow isn't the culprit, I set wallpaper as a single color and rebooted but after 1day the slow mouse and lag exist again
    I'll try to apply the patch anyway... :-)
