[SOLVED] Where would I place this code?

irgunII · 07-02-2014, 02:07 PM

I just found this code on another thread and it really works at stopping the terrible tearing when watching movies or scrolling etc.

Code:

nvidia-settings --assign CurrentMetaMode="VGA-0: 1600x900+0+0 { ForceCompositionPipeline = On }"

Where can I place this to have it automatically execute during startup of my system? Would it be rc.local? Or make it a bash script file and then where would I place it then?

The ideal place would be to start it along with your window manager (after X has launched).

EG; add the line to ~/.fluxbox/startup
Or if you use KDE/XFCE, you can use the gui tools to add it as a startup command.

Maybe you can try find this parameters in the xorg.conf file and define it there.

Actually, it is defined here http://http.download.nvidia.com/XFre...gtwinview.html
and looks like this would work (although I'm not sure which section should contain it):

Code:

Option "MetaModes" "VGA-0: 1600x900+0+0 { ForceCompositionPipeline = On }"

in your xorg.conf file.

The option is most likely supported in xorg.conf since it works from the command line.

A guy in this post https://devtalk.nvidia.com/default/t...63388/#3963388 put it in the Screen section. Although for some reason the xort.conf section text is white on white at the bottom of his post and I had to select the text to read it.

His line looks like this:

Code:

    Option         "metamodes" "nvidia-auto-select +0+0 { ForceFullCompositionPipeline = On }"

This worked by putting it in the 'Screen' section, like in the link you provided (though his post showed up just fine for me).

Thanks for finding that, jamesf!

Just want to say thanks for making this thread, i was curious about what this setting does, and added it to my own xorg.conf as jamesf suggested... i'm so glad it fixes the horrible tearing when scrolling! Will have to remember this one.
