[arch-general] Switch from AMD GPU to nvidia GPU

[Foxtrot Mike]

Hi all,

I was using amd r7 260x card without any problem with 'amdgpu' module. 
Now I want to install my new nvidia card (1050ti). I assumed that 
installing 'nvidia' package from pacman would be enough to be able to 
use my new GPU. (Apparently not).

The nvidia related  packages installed on my PC are:

~$ pacman -Qs nvidia
local/libvdpau 1.1.1+3+ga21bf7a-1
     Nvidia VDPAU library
local/nvidia 387.34-15
     NVIDIA drivers for linux
local/nvidia-utils 387.34-2
     NVIDIA drivers utilities

Upon rebooting after switching the cards, arch boots fine until "Reached 
target graphical interface" appears on the display. It seemed the PC was 
stuck, but switching to tty2 resulted in flashing keyboard lights. 
Which, according to a quick Google search, means kernel panic.

Moreover, [1] says that "the files are read in ASCII order, and by 
convention their names start with XX- (two digits and a hyphen, so that 
for example 10 is read before 20).". But I have multiple files in 
"/usr/share/X11/xorg.conf.d" starting with the same number 10:

~$ ls /usr/share/X11/xorg.conf.d/
10-amdgpu.conf            10-quirks.conf
10-nvidia-drm-outputclass.conf    40-libinput.conf

Please help me in getting my new card up and running.

Regards.
