Oke i tried, to get something that makes sense.

But the system basically goes completely random in failures, sometimes
green screen only fixable by enabling proprietary driver and then
disabling.

_If_ i get to a gui login it fails between seconds to minutes crashing
apps left and right even background daemons failing randomly.

After some digging it turns out that my model TU116 may not yet be properly 
supported.
https://nouveau.freedesktop.org/wiki/CodeNames/#nv160familyturing
https://nouveau.freedesktop.org/wiki/FeatureMatrix/

I would recommend that the kernel does not attempt to load the nouveau
driver for NV140/NV160 at all since they are not supported. it's imo
better to have a crappy low res display by default, then completely
random behavior.

And the low res can be fixed by enabling the proprietary driver.

It may also be best to have the ubuntu installer of the next point
release automatically install and activate the nvidia proprietary driver
for these models so new users don't get a low res display by default.
