GPU Drivers

AMD

NVIDIA

sudo pacman -S mesa nvidia-open

Make sure to also install envycontrol for switching between integrated and dedicated cards and nvtop to monitor GPU usage.

Using system clipboard in vim

Vim is useful during the installation for running the commands one by one. Using the system clipboard in this scenario is very useful.

• Install vim-gtk3
• Set the clipboard inside vim: set clipboard=unnamedplus

Increase archiso disk space

When needing space for installing packages on the archiso:

mount -o remount,size=1G /run/archiso/cow

Best practices

LTS kernel

Install linux-lts and linux-lts-headers alongside linux and linux-headers. The LTS kernel can be useful if some regression problem on kernel updates.

When using GRUB, regenerate the configuration file. This ensures the LTS kernel appears on "Advanced options" section.
