Disclaimer: I have personally tested every step of this. However, I'm not responsible for anything you do.
Pre-install

Boot Windows, install the latest updates, remove OEM bloatware, open Disk Management, and shrink the Windows partition to make room for Arch.
Download the latest Arch ISO and flash it with Etcher.
Control Panel &gt; Power Options &gt; Choose what the power buttons do &gt; Change settings that are currently unavailable > Uncheck Fast startup.

    Konsole delete word
By Raymond Li (Raymo111) 29 August 2021
To map shortcuts like Ctrl+Bksp/Del to delete words backwards and forwards in Konsole:

Go to Settings > Edit Current Profile... > Keyboard > Edit...`
Edit (or add) the following key combos if they don't already exist:


Key Combination
Output
(Explanation)


Backspace-Ctrl
\x7f
Backspace without Ctrl should just delete the character before the cursor


Backspace+Ctrl
\E\b
Backspace with Ctrl should delete the word before the cursor. ^H should be encoded as \x08 (ascii control character code in hex) but Konsole converts that to \b, it's code for backspace.

    1920x1080 HD webcam on Linux

So your webcam is giving you a 5:4 low-res video and you can't do anything about it?

Load the v4l2loopback kernel module:

sudo depmod -a
sudo modprobe v4l2loopback devices=1 max_buffers=2 exclusive_caps=1 card_label="VirtualCam"

You can do this persistently by creating a config file like video.conf in /etc/modprobe.d/ with the following in it:

  
## pwrstatd-powerfail.sh
#!/bin/bash
#.
#.
#.
# (append this)
# Send a desktop notif
sudo -u raymo DISPLAY=:0 DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus notify-send "Warning: Utility power has failed. Now running on battery." -i battery-caution -u critical -t 10000 -h 'string:desktop-entry:ups' -a UPS
