Certified on hundreds of devices

Ubuntu works alongside silicon vendors and manufacturers to enable and certify Ubuntu on a wide range of hardware. The certified hardware passes our extensive testing and review process in our labs, ensuring that Ubuntu runs well out of the box, and regression tests are performed before every system update is delivered.
