# ==============

# 1. Install Yaourt

# In the terminal window, type the following:
sudo nano /etc/pacman.conf

# Add the following repository:
[archlinuxfr]
SigLevel = Never
Server = http://repo.archlinux.fr/$arch

# Next, update and install:
sudo pacman -Sy yaourt

# 2. Install Catalyst

# While in the terminal open and type the following:
yaourt catalyst-test

# When asked to remove any conflicting packages, respond with yes [y].

#3. Post Install

# Make sure to install 'acpid' by typing the following:
sudo pacman -S acpid

# Then, enter each command below:
sudo systemctl enable atieventsd
sudo systemctl start atieventsd
sudo systemctl enable catalyst-hook
sudo systemctl start catalyst-hook

# Next, we have to write the initial config. Type the following:
sudo aticonfig --initial

# Lastly, we need to configure the bootloader. Follow the appropriate instructions for your bootloader:

# SYSLINUX BOOTLOADER
# Edit “/boot/syslinux/syslinux.cfg” and add nomodeset to the APPEND line, e.g.:
APPEND root=/dev/sda[x] rw nomodeset

# GRUB2 BOOTLOADER
# Edit the “/etc/default/grub” file, and modify the GRUB_CMDLINE_LINUX= line so it looks like this:
GRUB_CMDLINE_LINUX="nomodeset"

# Then:
sudo grub-mkconfig -o /boot/grub/grub.cfg

# 3. Last But Not Least…

# Reboot:
sudo reboot
