Dell XPS 15 9570 - graphics problem

Hi, I have the latest Dell XPS 15 9570 with hybrid graphics card. I'm currently facing many issues using Intel only. I have a lot of tearing, flickering (crazy lines), and ramdom freezing. This happening frequently and I'm not able to use the computer.

The only thing that is working is when I disable both "nouveau" and "intel" but xrandr doesn't give me any resolutions, performance is not good I think.
I have followed the Intel wiki tried and many settings. None worked

- I tried modesetting, intel driver xf86-video-intel
- options i915 enable_dc=1 enable_guc=3 enable_fbc=1 enable_psr=1 disable_power_well=0 modeset=1

Here some info:

Kernel: 4.14.51-1-lts
WM: i3

lspci

00:02.0 VGA compatible controller: Intel Corporation Device 3e9b
	Subsystem: Dell Device 087c
	Kernel modules: i915

01:00.0 3D controller: NVIDIA Corporation GP107M [GeForce GTX 1050 Ti Mobile] (rev a1)
	Subsystem: Dell GP107M [GeForce GTX 1050 Ti Mobile]
	Kernel modules: nouveau

$ cat /etc/mkinitcpio.conf

MODULES=(i915)

$ xrandr -q (without any drivers)

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 3200 x 1800, current 3840 x 2160, maximum 3840 x 2160
default connected 3840x2160+0+0 0mm x 0mm
   3840x2160     88.00* 

$ cat /etc/modprobe.d/blacklist.conf

# Intel
 install i915 /usr/bin/false
# install intel_agp /usr/bin/false

# NVIDIA - nouveau
blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off

Questions:
- If I do "modinfo i915 -p" I don't see any parameters set (1, 0, etc) even if I'M passing the options to my KMS. Is that normal?
- Does compton helps?
- Should I try nouveau instead? if yes should I use nvidia-lts or nvidia-beta?

While I cannot answer your questions (sorry) I am interested whether all or some of your issues have been resolved through recently updated bios/kernel/driver versions or by other means. (I am on the way to buy the laptop but stumbled over this thread.)

Re: Dell XPS 15 9570 - graphics problem

I recently had the same issue (I have a Dell Precision 5530) and found this page from the wiki and this option in the kernel solve the flickering:

i915.edp_vswing=2

I also installed

xf86-video-intel
nvidia
bumblebee

I found this webpage after I solve my issue: https://wiki.archlinux.org/index.php/Dell_XPS_15_(9550) with the same option for the kernel. Now it works perfectly.
