        <pre>After upgrading to latest git offloading to the Nouveau card wont work as
expected anymore.

It is quite easy to check:

xrandr --setprovideroffloadsink nouveau Intel

DRI_PRIME=1 glxinfo | grep "OpenGL vendor string"

which was giving the right Vendor for Nouveau, after upgrading it is the Intel
provider, despite the case that 

xrandr --listproviders

still lists the Nouveau card.

Reverting to a older driver (pre DRI3) resovles the problem again. So it may be
a incompatibility betweeen DRI2/3</pre>
