Installing Kubuntu 20.04 on an Optimus Laptop (ThinkPad T470p)
Unfortunately, installing Linux on an Optimus laptop still isn't very intuitive and straight forward. After installing the Nvidia driver, there's tearing. It's "easy" once you know how, but doesn't help a new user installing for the first time. In short, the steps are as follows:
1. Install Kubuntu 20.04 (LTS - Long Term Support).
2. Add the GPU driver PPA: sudo apt-add-repository ppa:graphics-drivers
3. Perform an update: sudo apt update
4. Install the Nvidia drivers: sudo apt install nvidia-driver-440
5. Reboot: sudo reboot
6. Open /etc/default/grub in your favorite editor.
7. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvidia-drm.modeset=1"
8. sudo update-grub
9. Reboot. Job done!
You can then change between the Nvidia and Intel GPUs using:
sudo prime-select nvidia (or sudo prime-select intel)
You can also use Nvidia Settings (a GUI app) and then choose between the following "Prime Profiles":
NVIDIA (Perofrmance mode).
NVIDIA On-Demand.
Intel (Power Saving Mode).
My next video will show how to install and configure the CUDA toolkit.
Enjoy Linux!
