XMG A507

This laptop is based on Clevo N850HJ(?), available with different configurations.

Installation
Installed in non-UEFI mode. Recommend Live-Distributions that do not boot into X11, since they will freeze most certainly. Use Gentoo's DVD.

Firmware
Required for WiFi.

Kernel
Latest (stable) kernel is recommended.

Keyboard backlight
clevo-xsm-wmi mod<ule required to get control over keyboard backlight. After building and loading this module, you can turn the backlight off or change colours etc.

This module may not work with kernel version 4.14 at this time, see the bug report.

nouveau
It might be required to add acpi_rev_override=1 to the kernel boot cmdline.

Additionally:

Given however that this disables runtime power management, you probably want to blacklist the module instead and use bbswitch to disable it. If nouveau is not loaded and GPU is off Xorg may also freeze. Hence, disable it only after you have successfully opened Xorg.

In the times you need it, do the following:

An already running Xorg server might crash, thus it's better to stop Xorg, then run these commands before starting Xorg again.

nvidia-drivers (propritary)
It might be required to add acpi_rev_override=1 to the kernel boot cmdline. No additional laptop-specified instructions were used, see NVIDIA.

This driver appears to be working at this point, external displays weren't tried though.

Freezes when starting Xorg, or when switching to tty from Xorg
