Thread: Screen tearing issues

  1. #1

    Default Screen tearing issues

    I have a nvidia 960 card and have the nvidia drivers installed. I am getting bad screen tearing, even when just scrolling text in Firefox.

    I found a temporary fix, that sometimes only lasts a few minutes. I change the compostor rendering back end to something random and then move it back to opengl 3.1. Should I just turn it off?

    I have:

    Scale Method: accurate
    rendering backend: opengl 3.1
    opengl interface: GLX
    tearing prevention full screen repaints

    I am not sure where else I can permentantly fix this. Any help is appreciated.

    did you try the nvidia-configure app
    what's the resolution and refresh rate?
    I've had 2 monitors with different aspect ratios and different resolution hooked up to my leap and had no tearing, I think I read somewhere that newer cards have a power saving feature that may cause issues, in the nvidia app see how your gpu is set up is performance or power save.

    I've had the same issues and found that this solved it for me: http://www.thelinuxrain.com/articles...vidia-try-this

    The steps in the link seems to have solved it. Thanks. That is a pretty obscure fix.

    I have one graphics card and two monitors with different screen resolutions(1920x1080 & 1920x1200) both with the same refresh. I did have a question.

    In /etc/X11/xorg.conf there is only one screen listed. Here is the relevant part of the file:

    Section "Monitor"
    Identifier "Monitor0"
    VendorName "Unknown"
    ModelName "Unknown"
    HorizSync 28.0 - 33.0
    VertRefresh 43.0 - 72.0
    Option "DPMS"
    EndSection

    Section "Device"
    Identifier "Device0"
    Driver "nvidia"
    VendorName "NVIDIA Corporation"
    EndSection

    Section "Screen"
    Identifier "Screen0"
    Device "Device0"
    Monitor "Monitor0"
    DefaultDepth 24
    SubSection "Display"
    Depth 24
    EndSubSection
    Option "CoolBits" "1"
    Option "TripleBuffer" "True"
    Option "metamodes" "nvidia-auto-select +0+0 { ForceCompositionPipeline = On }"
    EndSection
    I added the three Options based on the page linked. Is there a problem that there is not a Screen1?

    Are Coolbits and TripleBuffer needed?

    Also, what is the purpose of the files /etc/X11/xorg.conf.d/? Most of them just have comments in them. Should I have put the Options in 50-screen.conf?

    the xorg.cof.d files are the newer and preferred way to set up xorg. xorg.conf still works but the files in xorg.conf.d are the new way and represent section of the xorg.conf file. Best to leave them alone or use them instead of the xorg.conf file

    why not use the nvidia-configure app?
    as gogalthorp said xorg.conf is depreciated (but still works)
    you can try ti run nvidia-configure as root and set and save your preference in the xorg.conf, by default opensuse comes without an xorg.conf file

    I experienced a diagonal tear when scrolling in Firefox. I found a simple solution that worked for me.

    https://www.reddit.com/r/linuxmint/c...ling_graphics/

    The solution was to go to about:config in Firefox and change the setting gfx.xrenderer.enabled=true.
