Set up tips

Options are set using environment variables.

set_environment.sh - sets a minimum needed environment for those tools to work.

prepare.sh - generates high level scripts.

Use sudo -E <script> to run the script with root privileges and keep the environment.

To print all packages without installing them, set export print_pkgs=yes.

HiDPI boot

The Arch Linux ISO uses systemd-boot, so you can hit “e” when the menu appears and append parameters to the kernel line (or at the very end). Setting only this one should do the work:

video=1280x720

Set up WiFi

https://wiki.archlinux.org/index.php/WPA_supplicant#Connecting_with_wpa_passphrase

Connect to the network

wpa_supplicant -i <interface> -c <(wpa_passphrase MYSSID passphrase)

Then start dhcpcd for the interface

systemctl start dhcpcd@<interface>.service

Getting those tools

curl -L https://github.com/koponomarenko/arch_linux_setup_tools/archive/master.tar.gz | tar zx

Manual settings

HiDPI

Add the lines belows to /etc/default/grub:

GRUB_CMDLINE_LINUX="video=1280x720"
GRUB_GFXMODE=1280x720x32,1280x1024x32,auto
# Comment out this one
#GRUB_GFXPAYLOAD_LINUX=keep

Generate the updated GRUB config:

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

Power management

Add this kernel parameter (in bootloader) for STR(S3):

mem_sleep_default=deep

logind suspend delay

Delayed lid switch action should be set to 0.

/etc/systemd/logind.conf
...
HoldoffTimeoutSec=30s

bluetoothctl

Don't forget to start bluetoothctl with sudo.
Try NoInputNoOutput agent to eliminate request of any pass codes when pairing.

Network Manager
