DELL M4800

Introduction

This laptop, particularly the QHD+ variant, is extremely finicky and there are some minor caveats. First off, SystemRescueCD through UEFI seesm unable to detect valid monitor resolutions despite settings like nomodeset and won't boot. It's advised to just use BIOS.

The QHD+ variant also has an issue where TTYs aren't accessible once X has been started, as noted by Arch Forums.
