So, so saw I this endeavouros article and followed it. I did had optimus manager but wanted to try optimus switcher. I followed the article
It told to delete configs
6a. Any conf file that deals with the keyboard, touchpad, or networking can stay. Anything else, you can manually delete. For example, if you have a conf file name 20-nvidia.conf , it needs to be removed. You can remove it by typing sudo rm /etc/X11/xorg.conf.d/20-nvidia.conf
I delete that config “20-nvidia.conf”, it fricked the display, plasma-shell, etc. I could still run application web browser, file manager, terminal worked fined. In wayland, everything was fine. Thats for the intel mode, in nvidia mode graphics don’t launch only tty.
Edit- also i tried ( nvidia-inst -n ) which was the solution for previously same problem.
I did kept the config as backup nothing by returning it back
I thought we got you through all this once already and had it working? 
Edit: What is the current problem? You reverted to nouveau and what is the issue? No output to a second monitor? What is the current status?

yes, I saw this article and wanted to try optimus-switcher. So yeah back to square one but atleast igpu works and on wayland everything works fines, atleast not that bad for me
edit-

well the current problem is that nvidia gpu is not working, when i switch to it only black screen and also xorg acts weird any way to reset it?
Please use code tags when you post output.
Why are you using lightdm on KDE again? KDE uses sddm and i wouldn’t recommend changing it.
Okay doesn’t look like any driver id loaded. Please run this test and post the output.
nvidia-inst -t

Are you using the kernel parameter ibt=off first of all?
Edit: Post the url
cat /etc/default/grub | eos-sendlog
Please check if sddm is installed?
pacman -Qi sddm
yes, i am using ibt=off as the kernel parameter
this command is not working because i am using systemd-booter

If you are using systemd-boot then you have to do things differently. You have to add ibt=off in /etc/kernel/cmdline
Then run sudo reinstall-kernels
Also before this can you show me
systemctl status lightdm
I have already done that, 
systemctl status lightdm

Okay lets get back to sddm.
sudo systemctl disable lightdm
sudo systemctl enable --now sddm
Edit: Then run
systemctl status sddm
Edit: Waiting for you 
Edi2: Is there an issue?
Reinstall the nvidia drivers with.
sudo nvidia-inst
reboot
