This tutorial ensures there's no stdin/stdout/stderr (File Descriptors) as a potential performance optimization vector, furthermore no Login Manager is required nor a VT/Virtual Terminal (Getty/agetty). You can still execute a custom script (e.g. start.sh) but by default it skips login and spawns a Wayland compositor in TTYPath=/dev/tty1

Steps

1. Open your desktop environment in a different TTY (e.g. CTRL+ALT+F2).

2. Copy over all files to your editor.

3. CTRL+F and searh for following hardcoded values and replace them with what fits your system: | Value | Description |

VRR for fullscreen apps only

The idea behind this script is to only use VRR when a application is in fullscreen mode, here's the features:

• Has multi monitor support through a output whitelist config (I'd like this to be automatic in the future but there doesn't seem to be any way in swaymsg to identify if a output is VRR capable, one thing which comes to mind is checking EDID for VRR range).
• Determine if VRR needs to be toggled when a application is in fullscreen mode (which is how Windows does it usually and it's a option in Hyprland). This applies to:
  • Opening a app
  • Changing focus
  • Switching workplaces
  • Going into fullscreen mode (e.g. Youtube videos in Chromium)

Setup org.freedesktop.secrets the easy way with KeepassXC in Github Desktop

Overview

You might want to quickly authenticate with your Github Account to avoid having to manually configure GIT.

Although if you're using a lightweight distribution you might discover that you have to manually find a provider for org.freedesktop.secrets.

I encountered this problem and wanted to share my thoughts and general pointers from what I've learned!
