Thread: Flickering monitor

  1. #1

    Default Flickering monitor

    Hi,

    Problem: I have been using (up-to-date) Leap 15.0 (Please note that I am virtually a novice Linux user). There is pseudo-random flickering on my screen, which gradually increases its frequency when the computer resources being used more. I am not able to read a single typical-size paragraph without encountering a flickering.

    There seems to be similar threads regarding the same/similar issue, for example:
    https://forums.opensuse.org/showthre...er-or-dropouts
    https://forums.opensuse.org/showthread.php/527062-KDE-Plasma-desktop-5-flickering-screen

    I have amateurishly tried some of the solutions suggested thereat. Nevertheless, the flickering issue persists.

    Some information about the workstation is as follows:

    Default Re: Flickering monitor

    A good place to start is to try a different session type. IceWM is a nice small low load environment normally installed by default that is good for such testing. It typically will define whether the problem is with the environment (DE: Gnome, Plasma, XFCE, Cinnamon, etc.) or the foundation (Wayland or Xorg).

    DEs that can run in either Wayland or Xorg should be tried both ways.

    The information provided reports nearly nothing about the X foundation.
    Code:
    inxi -GxxxSa > somePlainTextFile.txt
    from any GUI terminal (Xterm, Gnome Terminal, Konsole, etc.) may be used to fill those gaps by pasting the file's content here without including the colors it uses onscreen.

    The inxi (nothing but an information collection and reporting script) provided by 15.0 (and 15.1) is ancient. Slightly more useful results might result from the current version available via its author's web site.

    Dear mrmazda,

    Many thanks for your reply.

    Please see the outcome of inxi -GxxxS > somePlainTextFile.txt below:

    Code:
    Resuming in non X mode: glxinfo not found. For package install advice run: inxi --recommends

    I will try to understand what the remaining of your post means since I am a bit novice regarding all you mentioned.

    Many thanks again.

    Have you managed to try any X session type in which output of
    Code:
    inxi -Gxx
    does not include Wayland, or reports "driver: modesetting" instead of "driver: nouveau"?

    Many thanks to both of you for your help.

    Eventually, I managed to get rid of this issue by simply installing the correct driver for the graphics card.

    Specifically, I have followed this link for the driver installation: https://en.opensuse.org/SDB:NVIDIA_drivers

    Thank you
