Public bug reported:

I have various hardware issues on a new Skylake laptop. The laptop has a
Nvidia GTX730 graphics card which can be switched off via bumblebee or
prime

1. Intel HD graphics 
Booting with intel graphics enabled results in a lockup loading lightdm or logging in results in the greeter screen appearing again.

2. Intel 8260 wireless
I have to run a recent mainline kernel (4.4 or similar) to get wireless.

3. nvidia card
Trying to install wily from a USB stick results in a splash screen lock up before it gets to the install screen. This appears related to the noveau drivers. I have to use the graphics ppa to install the nvidia drivers. But it is not an issue in the 3.9 kernel because to install what I have to do is:
i. install vivid (everything works except wireless)
ii. use wired network to install nvidia drivers
iii. use wired network to upgrade to wily
iv. use wired network to install mainline 4.4 kernel

4. Display brightness function keys
These don't work. Other function keys do. The other keys show output in acpi_listen but the brightness keys don't The settings applet can be used to adjust brightness, as can writing a value to /proc/blah

5. lshw shows other unclaimed hardware eg I think fingerprint scanner?
output attached.
