Arch Linux

Medium creation

Different methods:

cp

$ cp archlinux.iso /dev/sdX

cat

$ cat archlinux.iso > /dev/sdX

redirection with sudo to avoid 'Permission denied'

$ cat archlinux.iso | sudo tee /dev/sdX > /dev/null

pv

$ pv archlinux.iso > /dev/sdX

tee: include < or the input file gets zeroed out!

$ tee < archlinux.iso > /dev/sdX

tail

$ tail -c +1 archlinux.iso > /dev/sdX

dd

$ dd if=archlinux.iso of=/dev/sdX bs=4M conv=fsync oflag=direct status=progress

Monitor with 'progress' or 'pv'

$ progress -m

$ pv -d $(pidof cp)

Configuration

Enable network

via NetworkManager:

$ systemctl --now enable NetworkManager.service

via systemd-networkd:

$ networkctl list
$ vim /etc/systemd/network/20-wired.network
	[Match]
	Name=myadapter
	
	[Network]
	DHCP=ipv4

$ systemctl --now enable systemd-networkd.service
$ systemctl --now enable systemd-resolved.service
$ networkctl status

NTP via systemd-timesyncd

$ timedatectl set-ntp true

or

$ systemctl --now enable systemd-timesyncd.service

Swap file

$ dd of=/swapfile if=/dev/zero bs=1G count=1
# or
$ fallocate -l 1G /swapfile

$ chmod 600 /swapfile

$ mkswap /swapfile
# or (also set label)
$ mkswap -L linux_swap /swapfile

$ vim /etc/fstab
	/swapfile none swap defaults 0 0

$ swapon /swapfile
# or (activate all in /fstab)
$ swapon -a

# Check:
$ swapon

SSD optimizations: TRIM and swappiness

$ systemctl --now enable fstrim.timer

file_prio (default=200) minus vm.swappiness equals anon_prio

i.e. 200 - 100 = 100 [link]

$ sysctl -w vm.swappiness=100    # set immediately

Set on boot:

$ vim /etc/sysctl.d/99-swappiness.conf

DPI

Warning: !!! 96 DPI is not standard !!!

Calculate proper DPI for specific hardware at https://www.pxcalc.com/

Example: 27" 2560x1440 display

DPI: 108.79
Dot Pitch: 0.2335 mm
Size: 23.53" × 13.24" (59.77 cm × 33.62 cm)

$ pacman -S xorg-xrandr
$ xrandr --dpi 109
$ xdpyinfo | grep dots

Login/Desktop Managers in general:

$ vim /etc/xprofile
	xrandr --dpi 109

or

$ vim ~/.xprofile
	xrandr --dpi 109

LightDM specifically:

$ vim /etc/lightdm/lightdm-gtk-greeter.conf
	xft-dpi = 109

X Server:

$ vim /etc/X11/xinit/xserverrc
	exec /usr/bin/X -dpi 109 -nolisten tcp "$@"

or

$ vim ~/.xserverrc
	exec /usr/bin/X -dpi 109 -nolisten tcp "$@"

X Resources (if not set by Desktop Environment):

$ vim ~/.Xresources
	Xft.dpi: 109
	Xft.autohint: 0
	Xft.lcdfilter: lcddefault
	Xft.hintstyle: hintfull
	Xft.hinting: 1
	Xft.antialias: 1
	Xft.rgba: rgb

Firefox:

Note: Web pages appearance

Default DPI is 96. Change it in about:config by setting:

layout.css.devPixelsPerPx = x

...where x = DPI / 96

Example: 27" 2560x1440 display, x = 108.79 / 96 = 1.133229167

Note: Application window and menus appearance

Default DPI is 96. System DPI is only used if system DPI > 96. Force using lower system DPI by setting in about:config layout.css.dpi = 0
Default font scale in about:config is font.size.systemFontScale = 100
Do not increase Default zoom in Preferences
