List of computer vendors with Linux preinstalled.
This list contains vendors which also take care of the drivers and support.
Not simple computers like ARM or EOMA and such, just powerful computers which can compete with other commercial products.
Tuxedo Computers: German vendor.
Driver support and more stuff.
Preinstaled with an Ubuntu-like distro (kubuntu, lubuntu…) or Windows.
[Personal opinion]: I own one (book bu1406) and it’s really cool: 100% recommended.
Bad thing: The website is in german (they plan to translate and they speak english).
Slimbook: Spanish vendor.
They have 2 laptop models and a mini-computer.
They select Linux compatible components and develop custom software for the computers.
Cool desing, they have aluminum cases and such.
Preinstalled with many distros to select or windows.
[Personal opinion]: My sister owns one (slimbook classic) and it’s really nice very similar to a MacBook.
Ministry of Freedom: UK vendor.
Libreboot installed computers. Installed by the main developer of the Libreboot project.
Laptops are Lenovo ThinkPads. Not high end laptops but rugged and durable.
More freedom because of the libre booting system.
Preinstalled with Debian.
Lifetime support and many stuff more.
Good prices but shipping to Europe is expensive.
Laptops which protect your freedom. Very good looking.
A little bit more expensive than others.
Cool Linux laptops. Similar to Tuxedo and System76.
Fully free GNU/Linux distros preinstalled (Trisquel/Parabola/etc).
Some other places I didn’t test, I’ll keep investigating and adding more.
