Nvidia proprietary

Created Tuesday 02 April 2019

# This should have better performance than the bumblebee solution.
# If you've chosen not to install the dkms package with bumblebee,
# you will have to run a window manager from a second tty, to use the card.

USAGE!!!

# When the below is settled,
# To use it, you have to log out of the current desktop session
# then run nvidia-xrun

# Voila, the desktop now starts up using the nvidia card.

Install

$ pacman -S nvidia lib32-nvidia-utils bbswitch
$ cower -d nvidia-xrun

BUS id

# Get the bus id and create an xorg.conf file
$ $ lspci | egrep 'VGA|3D'

# Then create the xorg conf
$ sudo vim /etc/X11/xorg.conf

# Ait, add a kernel parameter to the MODULES array
# (edit the modules line, and add nvidia, nvidia_modeset, nvidia_uvm and nvidia_drm )
$ vim /etc/mkinitcpio.conf

modules=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)

# Edit, and add to the GRUB config
$ vim /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="nvidia-drm.modeset=1"

$ grub-mkconfig -o /boot/grub/grub.cfg

BBswitch - SHOULDN'T BE NECESSARY

# To enable it by default from start
# Use the Super User
$ su
$ echo 'bbswitch ' > /etc/modules-load.d/bbswitch.conf

# Turn it back off by default - also SU
$ echo 'options bbswitch load_state=0 unload_state=1' > /etc/modprobe.d/bbswitch.conf

# To check the status
cat /proc/acpi/bbswitch

# Turn it on manually
$ sudo tee /proc/acpi/bbswitch <<<ON

# And back off
$ sudo tee /proc/acpi/bbswitch <<<OFF
