Arch Linux Install with BTRFS, LUKS, and systemd-boot, dual-booted with a UKI and Windows 11 on a shared EFI partition

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

Pre-install

  1. Boot Windows, install the latest updates, remove OEM bloatware, open Disk Management, and shrink the Windows partition to make room for Arch.
  2. Download the latest Arch ISO and flash it with Etcher.
  3. Control Panel > Power Options > Choose what the power buttons do > 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:

  1. Go to Settings > Edit Current Profile... > Keyboard > Edit...`
  2. 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

Last updated 8 Sept 2021

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

  1. 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:
