Based on Canonical’s recently released Ubuntu 18.04 LTS (Bionic Beaver) operating system series and powered by Linux kernel 4.15, Pop!_OS Linux 18.04 is the second release of System76’s Ubuntu derivative and the best so far, featuring lots of changes, including a brand new installer, new power management features, firmware notifications, and proper HiDPI support. Among other noteworthy changes implemented by System76’s engineers in the major Pop!_OS Linux 18.04 release, we can mention full disk encryption, as well as a more streamlined boot experience where GRUB is no longer used for managing the boot process. Instead, there’s systemd-boot and System76’s own kernel stub, which handles the installation and updates of kernels on a UEFI partition.
