I have a few issues with my new setup.
1. The issues:
a). I have encountered a problem with modsetting happening randomly at boot.
The process is stuck indefinitely at message:
fb: switching to inteldrmfb from EFI VGA
I have tried ACPI settings like:'
acpi_osi=
acpi_osi=!
acpi_osi=! acpi_osi=Linux
acpi_osi=! acpi_osi='Windows 2009'
acpi_osi=! acpi_osi='Windows 2015'
acpi_osi=! acpi_osi='Windows 2018'
acpi_osi=! acpi_osi='!Windows 2009'
The last one seams to be most stable.
It might be a placeboo but I believe that it makes the problem less frequent.
Althouth it still happens like 1 in 6~7 times.
b). There is also an issue with powering down my discrete GPU.
I have performed a GPU driver installation according to:
https://wiki.archlinux.org/index.php/Bumblebee
Installed packages:
xf86-video-intel
nvidia
bumblebee
mesa
Scenarios:
- At this point I am able to login and start GUI session. Also glxspheres64 runs perfectly with and without optirun. But notice that bbswitch is not yet installed!
- If I install bbswitch, reboot and try to start GUI session I will face a kernel hung.
- Another option: install bbswitch, reboot, go to vtty2, power up NVIDIA GPU with
tee /proc/acpi/bbswitch <<< ON. Then I can safely start GUI session but I'm unable to power down discrete GPU. Error:
bbswitch: device 0000:01:00.0 is in use by driver 'nvidia', refusing OFF
- If I repeat all the steps from previous scenario but also blacklist 'nvidia' (with kernel parameter 'module_blacklist=nvidia'), then I can powerdown discrete GPU. However as a result optirun does not work. Error:
Cannot access secondary GPU - error: Could not load GPU driver
2. The specs:

There was much, much more, but these seamed most similar based on device vendor.

I got the same laptop in Nov 2019, was a b... to get running clean ...
this is what I have in my default/grub: i915.enable_execlists=0 acpi_osi=Linux acpi_backlight=vendor
I blacklisted nouveau in modprode.d
if I want to run on intel only:
I blacklist nvidia , nvidia_drm and nvidia_modeset
remove the file /etc/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf ( this file is added by me when I want to run on nvidia.)
if I want to run on nvidia I remove the nvidia blacklist file and copy 10-nvidia-drm-outputclass.conf to /etc/X11/xorg.conf.d/
$ cat 10-nvidia-drm-outputclass.conf

Identifier "intel"
