I ah haven't looked very hard but Lenovo is the only company I've seen offer Linux (Ubuntu) machines, limited for a very small number or devices though.

Do any other companies do the same?

The bigger players like Dell and Lenovo do and have for a very long time. Maybe HPE? Not sure

Then there are more bespoke vendors that cater specifically to Linux. System76 is probably the most well known, but there are many others.

I'm speaking mainly for laptops/desktops. For servers it's always been you just put whatever on.

Linux gets the most time on servers and containers but the desktop base continues to grow, so expect most problems to be there (bluetooth, wifi, etc.). Accessibility is getting much better.

Important relevant note:

Some companies offer "DOS" or "FreeDOS" computers. This is notably common in poorer countries.

These commonly do not really run DOS. They run a very old version of FreeDOS in a VM under Linux. HP uses Debian.

1. When you look for Linux machines, look in other countries than your own.

2. Include machines described as DOS machines. They are really Linux machines and will run Linux fine because they in fact ship with it.

Dell does (or did, haven’t looked in a few years).
