Is there a way to enable tearfree with amdgpu pro?

I am using Ubuntu GNOME 16.04 and I would like to know if there is a way to get amdgpu-pro driver to properly vsync. I have tried modifying the xorg file to look like:

Section "OutputClass" Identifier "amdgpu-pro" MatchDriver "amdgpu" Driver "amdgpu" Option "TearFree" "on"
EndSection

but all that managed to do is break the graphics part all together (gdm crashed or was stuck during next boot).

Create a file named /usr/share/X11/xorg.conf.d/99-tearfree.conf and containing Code:

Section "Device"
Identifier "Card0"
Driver "amdgpu"
BusID "PCI:1:0:0"
Option "DRI3" "1"
Option "TearFree" "on"
EndSection

You have the same option in the open source driver too: Use the command man amdgpu to see them all. In Xfce you use the desktop compositor to prevent window tearing.

Hope it helps

I feel very dumb, didn't notice that the default generated file is for Section "OutputClass", what was needed is Section "Device". It's all good now.
