Hi, I have a laptop with 2 graphics cards, one intel and one GeForce GT 750 M.
My gnome desktop use the former by default. And when trying to use nouveau I
got the same problem exposed in this bug.
Actually I am interesting in using the nouveau driver for HW decoding.

With the nouveau branch in darktama repo I could have it working with headless
display (using DRM). Though it looks not stable in the sense it sometimes works
after loading the kernel module nouveau.ko freshly built. And sometimes not.
And it seems not robust to init/deinit several times.
But better than nothing so it is still great !

I have noticed this error in kern.log:
