Intel tearing

Hi, I have screen tearing quite a lot for video and browsing. I found this wiki post and tried to emulate it. I created a file with the following content:

Section "Device"
	Identifier	"Intel Graphics"
	Driver		"intel"
	Option		"AccelMethod"	"sna"
	Option		"TearFree"	"true"
EndSection

at this location: /etc/X11/xorg.conf.d/20-intel.conf

However, now when I try to startup x from my login shell it complains that x found no screen. After removing the config file everything is working again as it should. I tried to find the x.log to post il also, but there is none in my /var/log folder.

Re: Intel tearing

What DE and login manager are you using?

Can you show us the rest of your X configs?

And especially the Xorg log.

Also let's rule out the obvious: Do you have xf86-video-intel installed?

The xf86-video-intel package isn't generally recommended for newer Intel graphics: https://wiki.archlinux.org/index.php/In … stallation

Re: Intel tearing

No, but certainly a good idea if you enforce it in the device config ...

Re: Intel tearing

If you uninstall the driver, remove the 20-intel.conf file, and reboot, does that put you back into screen tearing?

Do you have mesa, gstreamer-vaapi (and possibly) libvdpau-va-gl packages installed? We lack a basic hardware description--Intel chipset generation, etc. I ask because I've found that setup recommended for most modern Intel CPU/GPUs, and seems to be what functions best on this 4th Gen i7 Haswell laptop. (We're also assuming you've installed the intel-ucode.)

best regards
