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)

	[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

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)

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 Managers / Desktop Managers:

$ vim /etc/xprofile
	xrandr --dpi 109

or

$ vim ~/.xprofile
	xrandr --dpi 109

LightDM:

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

Xresources for non-DE:

$ 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
