Thread: KDE Desktop crashes and forces logout in Leap 42.3

  1. #1

    Question KDE Desktop crashes and forces logout in Leap 42.3

    Hello.
    I have a clean install via flash drive of Leap 42.3.
    The problem occurs regardless of the usage time, it could be from less of an hour to several hours, the DE freezes and after some seconds it just take me out to the login screen.
    This happens most of the time. But it could also happen that it do not return to the login screen.

    After trying some things, I found that the problem occurs when the cache memory reaches the physical RAM available.
    I tried with other DE like IceWM, and this problem did not occur.


    Any ideas to solve this?

    Thank you for your help.

    Are you on a system using Intel graphics? If so, see my question of yesterday, Plasma 5, Intel Graphics, Leap 42.3. I've not received an answer to my question yet, but you might want to try the suggested workaround (as I suspect the answer to the question will be Yes).

    As you said, the problem is that your computer doesn't have enough memory to run KDE. So, do you have 3 options: (i) put more memory; (ii) try to remove the background applications and plasma effects or the reccomended solution: (ii) use another desktop environment.

    Yeah, it has intel graphics.

    I just tried what you recommend, but I'm afraid that it didn't work on my system.
    I do that and then rebooted the system, and the GUI didn't started. Then I deleted that file, and immediately the GUI started.

    Maybe the configuration is different for my system. Anyway, I'll search for more info about intel graphics.

    I'm not talking about running out of memory, but the cache memory.

    For example, if I move some big files to an external drive, it crashes after some minutes, even if I'm not doing anything else.
    In Leap 42.2 I worked with 4GB+ of used RAM almost all the time with no problems. Here with 2GB of used RAM or less, it crashes.

    Yikes! Sorry to have used you unsuccessfully as a guinea pig.

    I'm thinking that this might be Bug 1050256.

    There's an update being prepared to fix this. In the meantime, try uninstalling "drm-kmp-default".
