As you may know, Raspberry Pi Foundation forked the Xfce desktop environment to create PIXEL, an optimized desktop environment for their Debian-based Raspbian operating system for Raspberry Pi computers. A couple of years ago, Arne Exton forked PIXEL and created an installer to allow users to install it on PCs and Macs. The latest release of Arne Exton’s Raspberry Pi PIXEL is a major version that upgrades the system base from Debian GNU/Linux 9 “Stretch” to the latest Debian GNU/Linux 10 “Buster” operating system series. It also ships with two Linux 4.19 kernels for PAE and non-PAE systems, Linux kernel 4.19.0-6-686-pae and Linux kernel 4.19.0-6-686.
