On 17th of March, DRI3 support was added to xf86-video-ati. However, to enable DRI3, you have to edit xorg.conf in order to enable it.

1) Create a file /etc/X11/xorg.conf.d/20-radeon.conf (Name of the file doesn't really matter, just make sure it sends with .conf) and add the following lines :
```
Section "Device"
   Identifier  "Radeon"
   Driver      "radeon"
   Option      "DRI3"
EndSection
```
Save the file, and reboot the system.

2) Now, check whether DRI3 is enabled or not by looking at Xorg.0.log file located at /var/log.

Great, thanks, that worked on Ubuntu too - there wasn't the directory though, but upon creation everything works.

There's one thing that bothers me, though - below the «DRI3 enabled» I also see the line:
```
(II) GLX: Initialized DRI2 GL provider for screen 0
```
Is that bad?
Are you sure? This action cannot be undone.
