  • Roadmap for official support for the Raspberry Pi 4

    With 19.10 release of Ubuntu Server, Canonical announced official support for the Raspberry Pi 4. The latest board from the Raspberry Pi Foundation sports a faster system-on-a-chip with a processor that uses the Cortex-A72 architecture (quad-core 64-bit ARMv8 at 1.5GHz). Additionally, it offers up to 4GB of RAM. We are supporting the Raspberry Pi 4 to give developers access to a low-cost board, powerful enough to consolidate compute workloads at the edge.

    The Raspberry Pi has established itself as a most accessible platform for innovators in embedded space. Canonical is dedicated to empowering innovators with open-source software. Consequently, Canonical endeavors to offer full official support for all the boards in the Raspberry Pi family. Canonical will enable both Ubuntu Server and Ubuntu Core for all the Pi boards.

    The Raspberry Pi 4 model B comes with different choices of RAM: 1GB, 2GB and 4GB. However, our official support for this board is currently limited to the 1GB and 2GB versions. Due to a kernel bug, USB ports are not supported out of the box in the official arm64 image on the 4GB RAM version. Kernel fixes have been identified by Canonical engineers. We are currently testing these fixes extensively. We will push updates within weeks, following successful test completion.

  • Canonical Working To Ramp Up Ubuntu Support For The Raspberry Pi 4

    Ubuntu 19.10 should work well on the Raspberry Pi 1GB and 2GB models while the 4GB version doesn't have USB ports working with the current Ubuntu Eoan packages. They have discovered a workaround of using total_mem=3072 for limiting the kernel to just 3GB of RAM in order to get USB functionality. But Canonical is working on proper updates to push out for enabling full USB support on the 4GB Raspberry Pi 4.

  • How to get Microsoft core fonts on Linux

    Linux is an open-source operating system. As a result, it is missing some critical components that users of proprietary operating systems enjoy. One big thing that all Linux operating systems miss out on is proprietary fonts. The most used proprietary fonts out there today are the Microsoft Core Fonts. They’re used in many apps, development, and even graphics design projects. In this guide, we’ll go over how to set them up on Linux. Note: not using Ubuntu, Debian, Arch Linux, Fedora, or OpenSUSE? Download the generic font package here and install the fonts by hand.
