30 years of XscreenSaver and Ubuntu for RISC-V

Canonical releases Ubuntu for StarFive’s VisionFive RISC-V boards, configuring a 7 Colour E-Ink display for Raspberry Pi, .NET 6 uninstalls Discord, and 30 years of XscreenSaver.

Ubuntu on VisionFive (RTheren)


    • Canonical is proud to announce the Ubuntu release for another piece of RISC-V hardware: StarFive’s VisionFive board.
    • VisionFive, the first generation of cost-effective RISC-V single-board computers, is designed to run Linux, with StarFive’s JH7100 vision processing SoC.
      • The JH7100 SoC is equipped with a 64-bit high-performance RISC-V dual-core processor with a 2 MB L2 Cache and running at 1.0 GHz.
      • It is equipped with 8 GB RAM, 40-pin GPIO header, and end-to-end hardware and software infrastructure.
    • And Canonical porting Ubuntu to RISC-V to become the reference OS for early adopters is a good choice.
    • This is a long-term collaboration between StarFive and Canonical.
    • Cindy Goldberg, Vice President of Silicon Alliance at Canonical states:
  • “Canonical and StarFive are partnering  to create an enterprise-grade Ubuntu image for the new VisionFive board, bringing open source software and open source hardware together for developers to build a broad range of computer vision applications at the edge. I can’t wait to see what developers are going to build with this VisionFive board and Ubuntu.“
  • There was a time long long ago when $179 for a 8GB pi-like device seemed silly. 
  • Not in this brave new world. 
  • Unless you want to spend $93 on the second gen quad-core Vision 5 2. 
  • Having an official image that just works ™ beats the snot out of installing something like Debian on the V1. 
  • But I would probably stick with the Fedora for now. 

30 years of XscreenSaver


  • If you have been using Linux for any amount of time you’re familiar with xscreensaver. 
  • It’s the thing you remember to disable when it pops up after a fresh install. 
  • With every monitor made in the last decade+ screensavers are a bit of a novelty. 
  • It’s still nice to travel down memory lane and look at the classics on something other than a 13” CRT. 
  • Next year xsnow turns 30.
  • Wow, Debian turned 29 and GNOME turned 25 last week, and now XScreenSaver turned 30!  That makes me feel old.
  • I have spent many hours of fun going through all the screensavers available in XScreenSaver over the years.
  • And I remember being excited back in the day when you can get screensavers for Linux that weren’t available for Windows, and wowing my friends.
  • I have used Fiberlamp, Julia, StarWars and XLyap as my default desktop screensavers for many years.

.NET in Ubuntu 22.04



  • I think I saw this coming, Canonical is incorporating Microsoft’s ASP.NET and .NET SDK into Ubuntu 22.04 LTS.
  • Open-source .NET has long been available in Ubuntu and other Linux distributions.
  • But this collaboration by Microsoft and Canonical will better secure the .NET software supply chain with enterprise-grade support.
  • .NET 6 developers can install the .NET 6 packages on Ubuntu with a single, simple command:  #sudo apt install dotnet6
  • Canonical and Microsoft built this .deb package together.
  • Canonical will also work in concert with Microsoft’s new distro maintainer .NET group.
  • One of Canonical’s goals is to secure the software supply chain from source to packages, eliminating the middleman.
  • I am not going to lie, I was a bit creeped out about this.
  • But I know it is good for the developer ecosystem, and Linux in general.
  • Microsoft is Microsoft when it comes to .NET. 
  • Open-source language with proprietary dev tools (debugging).
  • Installing this will cause apt to remove Discord
  • Will this open the door for .NET applications to be included in Ubuntu?
  • And before you pank, Fedora and Red Hat have offered .NET packages for years.
  • Telemetry collection is still opt-out. 

Slice of Pi

Configuring a 7 Colour E-Ink Display


  • You can pick up a colour eink screen for $83.99 in 2022. Neat. 
  • Tim walks us through everything we need to set up a nice Pi powered photo frame. 
  • The Inky board is really slick since it pops right on the GPIO pins. 
  • Easy to set the saturation. 
  • You can even use it to display web pages. 
  • Tim managed to make a self-contained version that fits in a normal picture frame. 
  • OMG!  Yeah, it is finally here,
  • And I don’t even care that it has a slower refresh rate than the black and white displays.
  • The screen takes around 15 seconds to do a full refresh.
  • Looks like the MicroCenter in Tustin by my house has 1 in stock as of yesterday.
  • And I am amazed it is priced under $100, at $83.99!
