Let's start from the beginning, because even though Wayland has been in development for over five years there is still a lot of misunderstanding of what it is. Wayland is a display server protocol that is intended to replace the X Window System. We've had X for 27 years, and computing has changed a wee bit in that time. Back in the olden days we had text terminals and every little pixel was precious. Now we have great honking graphics cards with more processing power than the servers and workstations of yesteryear, multiple displays, smartphones and tablets, embedded devices, and users who are not going to settle for colorful ANSI displays, but want complex 3D graphics.
