I run Freya with a 4.2.8 Kernel on a new Intel Skylake NUC i3. Hardware acceleration of the Intel HD 520 works with "i915.preliminary_hw_support=1" in Grub.
I don't have any Nvidia hardware.
On startup bumblebeed tries to start and then quits (cause no Nvidia). (there are a few dozen fails in dmesg when I look it up)
I think this isn't a big issue but why try to start a process that's not needed anyway?
So can I safely remove it? (e.g. with purge)
Or would this result in conflicts with remaining Nvidia drivers in the kernel? (as bumblebee would switch between integrated and dGPU)
