Powered by the Linux kernel 5.11 series, Ubuntu 21.04 (Hirsute Hippo) is here to introduce new GNU/Linux and Open Source technologies to users, such as the use of the next-generation Wayland display server by default, and the integration of a Flutter application development SDK.
Wayland by default is probably the biggest change in Ubuntu 21.04, providing better security and increased performance. However, Wayland won’t be enabled for all configurations as it doesn’t play well, yet, with NVIDIA graphics cards. As such, Linux gamers will be forced to switch back to the Xorg session.
