Spoken too soon :-)

By accident I also "fixed" my haswell's internal intel DRI and so the system is
now running much faster than before, but still powered by the intel's
rendering.

I'm surprised how fast the build in haswell's intel rendering is already :-)


But for the nouveau: It fails to initialise the acceleration, as far as I can
see.

The /var/log/Xorg.0.log shows: (i will attach the full log)

[    75.892] (II) NOUVEAU(G0): Opened GPU channel 0
[    77.893] (EE) NOUVEAU(G0): Failed to initialise context object: 2D_NVC0 (0)
[    77.893] (EE) NOUVEAU(G0): Error initialising acceleration.  Falling back
to NoAccel
[    77.893] (==) NOUVEAU(G0): Backing store disabled
[    77.893] (==) NOUVEAU(G0): Silken mouse enabled
[    77.893] (==) NOUVEAU(G0): DPMS enabled
[    77.893] (II) NOUVEAU(G0): RandR 1.2 enabled, ignore the following RandR
disabled message.


And so "DRI_PRIME=1 glxinfo | grep OpenGL" shows that it is running on intel
only:

OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile 
OpenGL core profile version string: 3.1 (Core Profile) Mesa 9.2.0
OpenGL core profile shading language version string: 1.40
OpenGL core profile context flags: (none)
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 9.2.0
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
