KDE Screen Tearing

I recently reinstalled arch as I got an SSD and ever since i've had problems with screen tearing.

I actually had the same problem on my other install but fixed it by following the wiki and this thread.

I made sure my nvidia-settings allow flipping and put the following in /etc/profile.d/kwin.sh:

export __GL_YIELD="USLEEP"

The file has -rwx------ privledges.

I'm not sure if there was something else I did last time that I missed this time, but the problem is still there.

Re: KDE Screen Tearing

Last time I used KDE with an Nvidia card I had to change the rendering backend from xrender to one of the OpenGL options. That got rid of the screen tearing in my case. Allowing flipping also helped. I don't recall where in system settings the rendering backend options are located, unfortunately.

Re: KDE Screen Tearing

Looking at the wiki, it now states

Warning: That may still not work properly with Xorg-server 1.8

So i'm a bit confused, should my settings be in

/etc/X11/xorg.conf.d/20-nvidia.conf

or in

/etc/X11/xorg.conf

If you don't have the latter then the former.

Re: KDE Screen Tearing

I had configuration data in /etc/X11/xorg.conf, i was wondering if that could be a problem but making one in /etc/X11/xorg.conf.d/20-nvidia.conf didn't help.
