<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>
