GDM Greeter on External Display (mutter 49+ / GNOME 47+)

The Problem

On modern GNOME systems (mutter 49+), the GDM login greeter ignores external displays and always appears on the internal laptop panel, even when an external monitor is connected and configured correctly in the user session.

Why the Common Fix Doesn't Work

Clean lsd -l Output with Icons But Without Symlink Targets

A robust one-liner and shell function to use lsd (LSDeluxe) with all its NerdFont-powered visual glory — while hiding symlink targets (⇒ path).

It preserves icons, formatting, and works beautifully in scripts and aliases.

Perfect for minimalist terminal users who love beauty without unnecessary clutter.

# Tags:  KDE  Konsole  Zsh z-shell

# I was having trouble with KDE Panels covering my Konsole sometimes 
# (would have to stop typing and click the panel to make it automatically disappear.) 

# It works by printing 2 new-line characters and then going 2 lines back up
