Basics and Nvidia Drivers

• To allow NVIDIA drivers to load at boot time on a Thinkpad, configure in the boot menu

On display Fractional Scaling, Google Chrome and VsCode may appear blurry, to resolve such issue:

• on Google Chrome, in the address bar, type chrome://flags, find Preferred Ozone platform, select Wayland;
• on VsCode, when launching from terminal, use code --ozone-platform=wayland; for the desktop icon to launch with such option, update its .desktop file as follows.

Alternatively, you can change system display platform from Wayland to X11 as follows. Note that it works fine on Ubuntu 22.04, but not very well on Ubuntu 24.04.
