[Solved] Compositor, screen tearing, and V-Sync

GrayBoltWolf · 2015-07-25 07:00:14

So as we all know the built-in compositor is trash on NVIDIA proprietary drivers. I am using Compton and that seems to help, but of course it can only sync to one monitor. My issue is this: Compton helps a lot, but is very resource heavy and I still get tearing on any video I play through VLC or Netflix via Chrome. When I play games I turn off compton for the performance boost.

What are we supposed to do? I love Linux but Gnome3 and XFCE both have horrible tearing on videos. Is it just the NVIDIA drivers?

You didn't mention the model of video card or the version of xfwm4 that you are using.

If you have a GeForce 500/600/700/900 series card, have you tried enabling the ForceFullCompositionPipeline option?

Also, xfwm4 has made some improvements in compositor performance recently. The changes haven't yet made it into a release and sit only in the git tree. Are you able to build from source to give it a try?

Thanks for the reply.

My setup is this:

Intel i7 4790k
EVGA GTX 970
XUbuntu 14.04

XFCE 4.10

I will try that fix for 900 series cards assuming that will work on Debian distros just fine.

Ok, so after adding that option to xorg or even doing it with the command I still have the same issues with compton on and off.

I'll try building the new XFCE next.

Ok, that didn't help either. Same issues. My windows are just fine, but any video tears so badly. Even on Gnome3 video tears horribly.

For ubuntu, the file should go in the /usr/share/X11/xorg.conf.d directory.

Which autogen/configure parameters did you use? Did you use:

--enable-compositor
--enable-xsync
--enable-epoxy
--enable-xpresent

Not sure where those go, but using Compton I have managed to like 99.99% get rid of tearing by a fix I found here: http://www.floweringdesign.com/fixing-s … -on-linux/

Basically it forces hardware acceleration for GPUs that aren't in the whitelist in Chrome. I noticed this when videos worked almost perfectly in Firefox.

If you use separate X screens as your multi-monitor mode, you need to start compton for the second display.

compton -d :0.1

I run all 3 of my monitors on the same Xscreen and compton syncs on them all just fine.
