nvidia-smi : command not found.
Dont know why, I downloaded the drivers from mhwd and also from the GUI utility.Both times, couldn’t get nvidia-smi
yes i already recognized the mess, your nvidia-drivers are missing completely. i don’t understand how this happened but okay ■■■■ happens. please install “linux519-nvidia” package. if it doesn’t work it’s propably because of some missing headers. if so please report but first try to install this package and try if it installs without additional headers.
edit: the additional headerpackage is called “linux519-headers”
This worked, thanks

well okay let’s recheck before reboot the following outputs
cat /etc/default/grub | grep GRUB_CMDLINE_LINUX_DEFAULT
echo $XDG_SESSION_TYPE
systemctl status optimus-manager
AND you run this 2 commands again ? (you said it stopped at first try, so rerun them)
sudo update-grub
sudo mkinitcpio -P
cat /etc/default/grub | grep GRUB_CMDLINE_LINUX_DEFAULT
GRUB_CMDLINE_LINUX_DEFAULT="quiet apparmor=1 security=apparmor udev.log_priority=3 optimus-manager.startup=nvidia nvidia_drm.modeset=1"
echo $XDG_SESSION_TYPE

you did a rerun of
sudo update-grub
sudo mkinitcpio -P
???
and what about
systemctl status optimus-manager
!?
updated above. Please check.
and you rerun
sudo update-grub
sudo mkinitcpio -P
?
Yes, this worked. Thanks a lot. My second monitor worked. My laptop screen does not though.
Did this too.
sudo systemctl enable nvidia-persistenced

this is a question of the system settings now ! you can activate both, or only one of them ! but this is only a system-setting of the used graphical-user-enviroment. since i’m not running i3 (i use plasma) you should check tutorials how to activate/deactivate and setup the displays on i3.
P.S.: just to make sure
glxinfo | grep server
is nvidia now ? right ?
I figured this out through ARandR. Both monitors are working now. Thanks a lot. I really appreciate it. 
Spent one whole day figuring this out. You have been a god-sent
Yes,
> glxinfo | grep server
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4

so enjoy your acer- 
and your weekend
You too
I’m agree with it is why when I 've recently changed my old Acer laptop taken a …Asus.
And Nice/great that you are an expert with Nvidia Card. 
I’m glad to see that your problem is solved thanks to the expert nvidia Olli.
Just to know, could you pass again this commands now that all is working for seeing the differences:
