I installed UBUNTU 16.04 LTS on my new bought SSD. I was happy with it, despite I was having some random "freezes" with Chrome and when I do
sudo apt-get update.
This morning I was trying to install Vivaldi browser, and after
sudo apt-get update and
sudo apt-get upgrade Ubuntu just froze, and I had to shutdown holding the power button. When I tried to boot it again selecting the distro on GRUB menu, the computer just "shut down", with my monitor light blinking. I tried to change the quiet splash for nomodeset on Ubuntu boot edit, but instead, a purple screen remains forever.
By the way, I am running on AMD GPU.
