Effects on my DELL Precision E6530: without notice it switches from nouveau to nvidia. Switching back to nouveau it hangs (need restart) and OK.
Using optimus:
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108GLM [NVS 5200M] (rev ff)
I'll try to use the upstream kernels and inform ...

It looks like upstream kernel doesn't solve completely the problem:
uname -a generic #201601101930 SMP Mon Jan 11 00:32:41 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
Linux carlosLT 4.4.0-040400-
However, it does no hangs anymore when I switch nouveau<->nvidia (355.11). No need to restart.
