Errors from my first post were because I forgot to add nvidia-lts during bumblebee installation. As @joekamprad mentioned. And booted with lts kernel, no wonder there were errors. I was dumb. Now the problem is that I can’t boot if I install bumblebee.

@manuel
I’ve tried to install bumblebee only for 4.20.6-arch1-1-ARCH. thats why I’ve send previous boot(4.20.6-arch1-1-ARCH) not current (using lts kernel)
I also can’t switch to console while trying to boot with main kernel Ctrl-Alt-F2/F3/F4/F5/F6 doesn’t work (have to turn off laptop using power button)
If I install nvidia-lts bbswitch-dkms, I won’t be able to boot with lts kernel too.

Reinstalled Antegros again. Added modprobe.blacklist=nouveau in boot menu before installation. Added modprobe.blacklist=nouveau before first boot, deleted nouveau driver. And so on from this instruction. I did this steps 3 times, result doesn’t change, I guess because everything that I do is the same

@manuel
Yes I can boot with Intel drives but what should I do to make bumblebee work, feel like nothing can help with this problem

@manuel
Now I also can’t boot with lts kernel

@manuel
nvidia-installer -b
Cannot install required packages ‘nvidia’ and ‘nvidia-dkms’ are in conflict
don’t know how to refuse installation of nvidia

@joekamprad
Thank you. stupid mistake

@joekamprad
I did sudo pacman -Rsc xf86-video-nouveau and sudo gpasswd -a nad video 2 days ago
nothing has changed.
After that I found information that bbswitch may be configurated (don’t know how to name this correctly) for another kernel, not for kernel I’m using. as I couldn’t boot with 4.20.6.arch1-1 and used linux-lts 4.19.18-1 I thought it may be true because nvidia driver was 415.27-3.
so I did
sudo pacman -Rsc linux (bbswitch-0.8-194 nvidia-415.27-3 linux-4.20.6.arch1-1 were delited after this command)
sudo grub-mkconfig -o /boot/grub/grub.cfg
reboot
after that during boot I had only lts Kernel so dicided that I did this correctly
delited bumblebee
sudo pacman -Rsc bumblebee
and tried to install bumblebee again using the same commands but linux-4.20.6.arch1-1 was installed again altough I didn’t mention linux after pacman -S. I don’t know why. So the were bbswitch-0.8-194 nvidia-415.27-3 linux-4.20.6.arch1-1 again
