Hi!
I want test the LINUX_LIBRE_kernel on my system, is it possible to install
it in Ubuntu Mate?
I found this Link: (How to for Ubuntu etc.)
https://jxself.org/linux-libre/
...for a test, I do this:
sudo su
wget -O - https://jxself.org/gpg.asc | sudo apt-key add -
apt-key finger
Make sure that you see the fingerprint:
F611 A908 FFA1 65C6 9958 4ED4 9D0D B31B 545A 3198
then:
sudo apt update
sudo apt install linux-libre-5.2
Output:
E: Unable to locate package linux-libre-5.2
E: Couldn't find any package by glob 'linux-libre-5.2'
E: Couldn't find any package by regex 'linux-libre-5.2'
maybee, not supported in Ubuntu-Mate?
I've done:
sudo apt-key adv --keyserver pool.sks-keyservers.net --recv-keys F611A908FFA165C699584ED49D0DB31B545A3198

Which is the right signing key for?
http://linux-libre.fsfla.org/pub/linux-libre/planet planet main
I don't find it 
I found the key here:
Where get the build of .deb?
Architecture amd 64 bits
Operating System Debian Wheezy on fully free repositories
Mirror: You can add to your mirror list our mirror
get the key then get our repo
sudo wget http://linux-libre.fsfla.org/pub/linux-libre/planet/archive-key.asc
added to PPA: "sources.list"
deb http://linux-libre.fsfla.org/pub/linux-libre/planet planet main
I did
sudo apt update

...strange thing...
a little how-to 
I wrote...
Open... 'mate-terminal'
sudo pluma /etc/apt/sources.list
or
sudo leafpad /etc/apt/sources.list
then add this:
####//:"LINUX.LIBRE-KERNEL":\####
deb https://mirror.cyberbits.eu/linux-libre/freesh freesh main
Visit this site if the mirror above is down and copy
to your sources.list another one.
Save the file, exit your text-editor.
sudo wget -O - https://jxself.org/gpg.asc | sudo apt-key add -

Make sure that you see the fingerprint:

then:
sudo apt install linux-libre-5.2
If the kernel parameters in "/boot/grub/grub.cfg" are not set automatically
then adjust it manually.
'REBOOT'
Open... 'mate-terminal'

hmm...
I booted the kernel, I can login into my system, all is working without
the "nvidia-driver-430"
I boot with kernel "5.0.0-23-generic" ...the "nvidia-driver-430" is working.
What to do? How can I get "nvidia-driver-430" working with the linux-libre-5.2 kernel?
I use the OpenSource driver of nvidia430.
I asked the support team of Linux-Libre why I can't use nvidia-driver-430
with "linux-libre-5.2" kernel.
I received an email from the support team of Linux-Libre.
They said because the firmware BLOBS of the proprietary Nvidia-drivers were removed in
the Linux-Libre-Kernel.
So, you can't use them.
Ok, I think I use the "linux-libre-5.2" kernel in a VM.
In a VM I can live without 3D acceleration.
