X11

  • .Xresources - save this in a ~
  • edit '/etc/X11/xinit/xinitrc': remove all items in a section 'start some nice programs' (at the end of file) and write following:
    exec i3 &
    xterm &
    setxkbmap -layout 'us,ru' -option 'grp:caps_toggle,grp_led:caps' &
    xxkb (it must be installed, makes a individual layout for each window)
  • add 'startx' to the starting-script

    • Arch network

    1. systemctl stop dhcpcd@enp4s0.service
    2. systemctl start dhcpcd@enp4s0.service
    3. # start cable network
    4. ip link set wlp2s0 up
    5. iw dev wlp2s0 scan|grep -i ssid
    6. wpa_passphrase Door ********
    7. wpa_passphrase Door ********>>/etc/wpa_supplicant/wpa_supplicant.conf
    8. # in vi editor: kill all empty examples: :1306,1688d
    9. wpa_supplicant -i wlp2s0 -c /etc/wpa_supplicant/wpa_supplicant.conf
