Additional Configuration Info

• to enable pacman parallel download follow Arch Wiki | pacman / Enabling parallel downloads
• to speed up pacman packages download, update mirrorlist by something like sudo reflector --sort rate --connection-timeout 2 --download-timeout 2 --threads 10 --save /etc/pacman.d/mirrorlist
• if you can't log in after a couple of failed attempts it is probably caused by faillock Arch Wiki | security / Lock out user after three failed login attempts
• to change sudo timeout follow Arch Wiki | sudo / Tips and tricks / Reduce the number of times you have to type a password
• ranger is not previewing anything when user is root. This is on purpose and should be toggled with zp (enable syntax highlighting with zv) GitHub | ranger / issues
• tmux is not loading config from $XDG_CONFIG_HOME/tmux/tmux.conf on old versions
• nsxiv images in thumbnail mode and .HEIC are rotated according to EXIF:Orientation tag but they shouldn't
  • maybe because of imagemagick package required by betterlockscreen
• for virtualbox to function properly, add ibt=off to kernel parameters
  • to add shared folder, install virtualbox-guest-iso (or virtualbox-guest-utils), run Devices -> Insert Guest Additions CD Image and My Computer -> CD Drive (VirtualBox Guest Additions) -> VBoxWindowsAdditions.exe.
  • add user to vboxusers group to detect USB devices
  • shared clipboard (requires guest additions): highlight the Guest VBox in the VirtualBox console, open General -> Advanced. Here you can choose between various Shared Clipboard settings: Disabled, Guest to Host, Host to Guest or Bidirectional
• to connect MTP devices (e.g. Garmin), use libmtp
• to make printer work use Avahi
• suspend vs hibernate:
  • suspend:
    • seems to drain a lot of battery, but it might be because of lid opens in backpack and laptop turns on
    • investigate the effect of disabling waking on lid open
  • hibernate:
    • doesn't work by default
    • general configuration instruction: Arch Wiki | Power management / Suspend and hibernate
    • create swap for hibernation (maybe not needed): Arch Wiki | Swap / Swap file creation
    • add kernel parameters: Arch Wiki | Kernel parameters / systemd-boot
    • in case "Not enough swap space for hibernation": [SOLVED] Fail to hibernate "Not enough swap space for hibernation"
• to connect meshtastic:
  • install driver from aur (maybe would've worked w/o it) and reboot
  • sudo pacman -S esptool
  • ll /dev | grep USB
  • esptool.py -p /dev/ttyCH343USB1 chip_id
  • Download release from github
  • ./device-install.sh -p /dev/ttyCH343USB1 -f firmware-tbeam-2.1.19.eb7025f.bin
  • meshtastic --port /dev/ttyCH343USB1 --info
  • meshtastic --port /dev/ttyCH343USB1 --set lora.region 'RU'
• to set up wifi hotspot (shares VPN as well): Arch Wiki | Software access point | linux-wifi-hotspot
• to download/upload config to baofeng walkie-talkie:
  • install drivers (another source)
  • install software from baofeng website
  • reboot
• to fix screen tearing enable vsync with glx backend in picom (already enabled in picom.conf)
• to fix openvpn-install script on arch linux server apply openvpn-install.diff
• to use this setup on ROS embedded device, apart from sourcing ROS setup files, configure ip addresses like this in shell profile:

  export ROS_HOSTNAME=$(ip route | grep wlan0 | grep src | grep -o '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}' | tail -1)
  export ROS_MASTER_URI=http://$ROS_HOSTNAME:11311

• to enable zoom in st (to make it work in neovim -- disable mouse :set mouse=):

  { ControlMask,          Button4, zoom,           {.f = +1} },
  { ControlMask,          Button5, zoom,           {.f = -1} },
  

  put them before XK_ANY_MOD masks
• to copy output, add:

  static char *copyoutput[] = { "/bin/sh", "-c", "st-copyout", "externalpipe", NULL };
  { MODKEY,               XK_o,           externalpipe,   {.v = copyoutput } },
  

• if laptop immediately wakes up after suspend or hibernate -> maybe I am touching touchpad?
• to use local X11 display from remote server via ssh, use:
  • add -listen tcp to X11 startup args /etc/X11/xinit/xserverrc
  • xhost +
  • export DISPLAY=IP:0.0
• gparted might not format partition because of udiskie automount; disable it

ToDo

• make rm command to move to trash folder but not delete
• open all terminal windows at tmux
  • tmux attach-session -t random \; new-window ranger
• come up with solution for notes management
• rewrite mute script to iterate through all sources and mute/unmute them
  • display muted status as every output is muted
• complete deletion script of marked photos in nsxiv
• preinstall coc extensions in a setup script, which is useful for docker environments; begin here and here
