SNA on xf86-video-intel 2.20.0

xf86-video-intel 2.20.0 brings a couple of changes regarding SNA. The first change is that the choice between UXA and SNA (the 2 available acceleration architectures for the Xrender protocol) can be done without rebuilding the driver.

However, SNA is no longer enabled by default, even if built in. To enable it, the following snippet in your /etc/X11/xorg.conf will do the trick:

Section “Device”
Identifier “intel driver”
Driver “intel”
Option “AccelMethod” “sna”

That’s all for now.
