Need help with the HOWTO: Ubuntu Server guide

[Hopelessone]

I dont have the 4.2.0 kernel in the stock install of 14.04.5 ubuntu so i did this...

Code:

sudo su
cd /tmp
wget "http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2-wily/linux-headers-4.2.0-040200-generic_4.2.0-040200.201510260713_amd64.deb"
wget "http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2-wily/linux-headers-4.2.0-040200_4.2.0-040200.201510260713_all.deb"
wget "http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2-wily/linux-image-4.2.0-040200-generic_4.2.0-040200.201510260713_amd64.deb"
sudo dpkg -i *.deb

dpkg --list | grep linux-image

sudo apt-get purge linux-image-4.4.0-31-generic
sudo apt-get purge linux-image-4.4.0-45-generic 
sudo apt-get purge linux-image-extra-4.4.0-45-generic 
sudo apt-get purge linux-image-generic-lts-xenial 

sudo update-grub

and I did:

Code:

sudo apt-get remove fglrx
sudo apt-get install fglrx

and still i get:

Code:

clinfo
modprobe: ERROR: ../libkmod/libkmod-module.c:809 kmod_module_insert_module() could not find module by name='fglrx'
modprobe: ERROR: could not insert 'fglrx': Function not implemented
