Cause: Missing graphics driver or incorrect display manager. Solution: Boot back into the USB, chroot, and install the correct driver.
# For NVIDIA (pure pain)
sudo pacman -S nvidia nvidia-utils
# For Intel
sudo pacman -S xf86-video-intel
sudo pacman -S i3-wm i3status dmenu terminator nitrogen
# For Wayland (pure modern)
sudo pacman -S sway waybar alacritty wofi
The greatest threat to a pure Onyx install is neglect. Because Onyx follows Arch's rolling release model, partial upgrades break the system.
The Golden Rule: Never run sudo pacman -Sy followed by pacman -S package. Always do a full system upgrade: pure onyx install
sudo pacman -Syu
Before upgrading, check the Arch Linux News for manual interventions (e.g., required .pacnew file merges). Onyx users should also check the #onyx-announcements channel on their Discord or Matrix server.
Because Onyx is pure Arch, you can install the full DE exactly as KDE intends. Cause: Missing graphics driver or incorrect display manager
# Pure KDE Plasma sudo pacman -S plasma-meta konsole dolphin
iwctl [iwd]# device list [iwd]# station wlan0 scan [iwd]# station wlan0 get-networks [iwd]# station wlan0 connect "YourSSID" [iwd]# exit
useradd -m -G wheel,audio,video,storage -s /bin/bash yourusername passwd yourusername
A pure system is a configured system.
# Time zone (example for EST)
ln -sf /usr/share/zoneinfo/America/New_York /etc/localtime
