Tear-free disabled in Intel Graphics, tearing in Xubuntu

Solution 1:

TearFree is disabled by default. To enable it create the directory,

sudo mkdir /etc/X11/xorg.conf.d/

Then add to the file /etc/X11/xorg.conf.d/20-intel.conf

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

Solution 2:

I have run into this problem with xubuntu 16.04.2. Tear free stopped working. In my case, for some reason the package xserver-xorg-video-intel was no longer installed. Xorg.0.log said the intel module was not loaded, and that instead the modesetting driver was loaded, and as great as that may be, the config file to set tear free was being ignored. Restoring the package fixed things, tear free worked again. I don't know if this is how it is supposed to be: the xserver-xorg-video-intelpackage description says its use on post 2007 hardware is discouraged, but horrible tearing graphics is much more discouraging.

The package in my case is actually xserver-xorg-video-intel-hwe-16.04
