Ubuntu 16.04 - problems with MSI GE62 6QD (i7-6700hq, nvidia gtx 960m)

I have problem with ubuntu 16.04 on MSI GE62 6QD laptop.

Specs:

CPU i7-6700HQ
GPU1 Intel HD 530
GPU2 NVidia GeForce GTX 960m

Problem:

I can't get things to work. First problem was to boot live CD. I've get freeze on loading. Adding acpi=off to GRUB parameters finally makes system installation possible.

After install I've noticed few issues. Automatic update get stuck on updating unattended-upgrades. After installation of properiaty nvidia drivers and switching to it I noticed, that Unity is not smooth. Moving windows is not smooth and tearing. I installed also intel drivers via 2.0.2 installator from 01.org and switched to it.

I can't shutdown/reboot system without freeze now.. I've also install guc and dmc firmware from 01.org. System randomly shows errors system error detected and in /var/crash/ I can found random applications errors (including compiz, chromium-browser.

Another issue is fact, that when I'm on Intel graphics and switch to TTY I can see spam of pci bus error messages. I found that adding pci=nomsi to GRUB is solving this problem and this is true - I never saw that error after this.

Next issue - writing lspci in terminal causes system freeze, I can't even switch to TTY.

Webcam is not installed in the system and I don't know how to do it (I cant even lspci, lol.).

Even on Intel graphics I feel, that system isn't so smooth as it supposed to be. (resizing windows, launching firefox, scrolling etc.)

I tried many things which I can found even on AskUbuntu, including:

many nvidia driver versions (361 to 375)
different compiz settings (refresh rate, composite, sync to vblank)
updating to kernel 4.8
intel_idle.maxcstate=1 or 0 GRUB parameter
installing system from that guide: 

I don't know what to do and I WONT give up and back to Windows. Please, anyone can help me? I just want to use linux on new laptop..

EDIT: After downgrade to kernel 4.4.0 at least I can shutdown/reboot system and lspci works

EDIT: I found that function key is enabling/disabling webcam - it works too. Looks like I must look only at compiz performance
