"Also are you using DRI2 or DRI3?"
Not sure how to check it. The `cat /var/log/Xorg.0.log | grep -i DRI3` comm=
and
gives me: `[ 40491.158] (=3D=3D) RADEON(G0): DRI3 enabled` so looks like it=
 is only
enabled, but not probably not used, when I look for DRI2 the outpout looks =
like
this: http://pastebin.com/Nevad1GD=

Also in xorg.conf.d I have file `10-amdgpu.conf` with content:
Section "OutputClass"
        Identifier "AMDgpu"
        MatchDriver "amdgpu"
        Driver "amdgpu"
EndSection

but in `10-monitor.conf` I have setup at the end of file (which works fine,
except for issues I've mention earlier):
...
Section "Device"
    Identifier "Device0"
    Driver "intel"
EndSection

Section "Device"
    Identifier "Device1"
    Driver "radeon"
EndSection

Not sure what's the difference between radeon and amdgpu driver in this cas=
e,
can 10-amdgpu.conf be related to amdgpu-pro? I've tried amdgpu-pro few weeks
ago but that didn't work out at all so I decided to stick with opensource o=
ne.

Asking because I would like to try to enable DRI3 and recently it got kind =
of
harder to understand what drivers for radeon are in use (recently I think it
was only mesa and fglrx). To use DRI3 should file look like `20-radeon.conf=
` as
filename and inside:
Section "Device"
   Identifier "Radeon"
   Driver "radeon"
   Option "SwapBufferWait" "0"
   Option "DRI" "3"
EndSection
