Notes from installing Ubuntu 18.04 on a Lenovo ThinkPad X1 Extreme, with nvidia graphics.
- Turn off secure boot in the BIOS.
- When choosing operating system to boot (options will be Ubuntu, or Install Ubuntu...) hover over Install Ubuntu.
- Press
e
- Go to the line that contains
quiet splash
and appendacpi=off
- Press
ctrl
+x
to boot
Add nvidia PPA to ubuntu
sudo add-apt-repository ppa:graphics-drivers/ppa
Update and install
sudo apt update
sudo apt install nvidia-415
I'm sorry I didn't record what version I was on when I was doing this. Since doing this I think I might have updated the bios.
I subsequently installed pop!_os and can highly recommend it. It is built on top of ubuntu.
