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: t 19 00:05:02 nb-716 kernel: [ 737.034566] nouveau 0000:01:00.0: DRM: resuming kernel object tree...
