KDE Yocto Demo Setup for FOSDEM 2024

This page provides the basic information about the demo setup that is available at the KDE stall at FOSDEM 2024.

What can I see there?

  • a Raspberry-Pi5 development board
  • a OLED HDR touch screen
  • a Plasma mobile Yocto image with KDE Frameworks / Plasma / Applications in RC-2 version of the Qt6 Megarelease

What is this demo setup about to present?

  • show the state of the Yocto meta-layers: read mere at https://community.kde.org/Yocto
  • give a feeling about how Plasma Mobile feels on an embedded non-phone device
  • give a sneak-peak into Plasma 6
  • give an example of how such embedded boards can be used

FAQ

  1. Why is the demo not on RISC-V hardware?
    • Because for no RISC-V board (at least to those we have access) the GPU driver is stable enough to handle a Wayland compositor together with complex QtQuick applications

Demo Troubleshooting

  • for constant display output, open the drop-down settings menu and activate "caffeine"
