Linux Bug: Disable Framebuffer Nvidia free Driver Nouveau for hanging xserver-xorg (for Servers)

Problem: Nouveau the free Version of the Nvidia Display Driver crash if you switch to Console or kill the xserver-xorg.Its enabled by default inside the KERNEL!! this WAS NOT DEFAULT at last DECADES!! (DEBIAN 3.0-5.0 never used it!, cause bugs and hanging Servers)

Solution:

echo 'blacklist nouveau' &gt; /etc/modprobe.d/blacklist-nouveau.conf

then edit with $sudo nano /etc/default/grub

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2&gt; /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="noquiet nouveau.nomodeset=0"     #on Ubuntu set "nomodeset noplymouth"
...

update grub Loader with

sudo update-grub2

REMARK: THIS MUST BE USED AT SERVERS FOR STABILITY!! REMOVE / BLACKLIST ALL UNEEDED DRIVER MODULES LIKE SOUND!
