Schenker XMG P407

Installing XubuntuXubuntu/Arch on the P407

I stumbled across some big problems with nouveau, like i could not login or even turn of the pc properly.

First fix already happens on booting the live-cd.
You need to change the boot entry for the Installer from:

linux options options ... 
to
linux options options nouveau.blacklist=1

Press F10 to apply and continue booting.

If it still does not work you need to add acpi=off additionally.

Now install xubuntu to your liking, it might not be able to turn off successfully, just ignore that and hard reset the laptop, it should boot normally.
You need to add the same lines again to the grub bootloader as to the live-cd, so if the grub menu doesn't appear for you, boot from a live cd again and skip the next step.

Search again for the linux line and add the nouveu.blacklist=1 to the end

linux options options ... 
to
linux options options nouveau.blacklist=1

Press F10 to apply and continue booting.

Now login and add /etc/default/grub as root.
There you look for the line

GRUB_CMDLINE_LINUX_DEFAULT=options

and replace it to

GRUB_CMDLINE_LINUX_DEFAULT=options noveau.blacklist=1

and apply it with sudo update-grub2.

Now to installing the latest drivers:

Remove all existing drivers on your system and update the cache.

sudo apt-get purge nvidia*
sudo apt-get update

Now look for the latest nvidia driver via apt-cache

sudo apt-cache search nvidia binary

and install the latest one (a.k.a the one with the highest number). There might be stability issues, so research a bit if there is a recommended, older one. In my case i had to install nvidia-384.

sudo apt-get install nvidia-384

The system should now be working.
