Nvidia GTX 860M and screen tearing!

barmadrid · 2016-08-05 04:24:21

I am experiencing screen tearing with my Nvidia 860M card in Gnome 3.20.2.
I followed the Arch guide regarding Nvidia tearing, but it did not help. Tearing while watching videos and scrolling (Firefox or file manager, both).

Here is my "screen" section of 20-nvidia.conf:

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "Stereo" "0"
    Option         "nvidiaXineramaInfoOrder" "DFP-0"
    Option         "metamodes" "1920x1080_60 +0+0"
    Option         "SLI" "Off"
    Option         "MultiGPU" "Off"
    Option         "BaseMosaic" "off"
    Option         "metamodes" "nvidia-auto-select +0+0 { ForceFullCompositionPipeline = On }"
    Option         "AllowIndirectGLXProtocol" "off"
    Option         "TripleBuffer" "on"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

Running latest Nvidia driver 367.35 and Kernel 4.6.4-1

Any help on fixing the tearing?

It seems like removing that "metamodes" line from 20-nvidia.conf and running this command:

nvidia-settings --assign CurrentMetaMode="nvidia-auto-select +0+0 { ForceFullCompositionPipeline = On }"

is fixing the problem, but how do I make it to autostart each time?

For me, I did 2 things following the wiki (but notice a different location than stated by the wiki for 20-nvidia.conf), and it stopped tearing:

/home/colin %cat /etc/X11/xorg.conf.d/confs/20-nvidia.conf

    SubSection     "Display"
        Depth       24
    EndSubSection
		Option         "metamodes" "nvidia-auto-select +0+0 { ForceFullCompositionPipeline = On }"

EndSection

and

/home/colin %cat /etc/profile.d/kwin.sh
export KWIN_TRIPLE_BUFFER=1

The 20-nvidia.conf is basically what you tried, (but was yours in /etc/X11/xorg.conf.d/confs/?). The extra step I took was to create /etc/profile.d/kwin.sh with that one line in it. Of course, my tearing problem was in KDE Plasma which is why I created kwin.sh. I don't know if there's an extra step like this that you can take with Gnome.

This line of code does the same thing as adding "the metamodes line" to the 20-nvidia.conf file. Make sure the conf file is in the correct location.
