openSUSE Leap 16 Install FIX (Black Screen?) — NOMODESET, GRUB Tweaks, Codecs & First Apps
Struggling to install openSUSE Leap 16? Black screen with a blinking cursor? 😵💫 In this video I show the exact fix (✅ nomodeset) and the post-install tweaks you need: GRUB edits, NVIDIA driver tips, Agama installer quirks, Packman/OPI codecs status, Flatpak/Flathub setup, and my must-install apps (OBS, Flameshot, NotepadQQ, Chrome). Whether you’re on bare metal or a Proxmox VM, this walkthrough gets you from stuck to booted and usable—fast.
👉 If you’re hitting issues, follow along step-by-step. I include quick commands and show you how to revert nomodeset after first boot so you get full resolution again.
