Canonical's Big Bet on RISC-V: A Fully Functional Desktop Session Coming Soon

Taking Ubuntu to New Heights with the Latest RISC-V Innovation

Canonical is making a significant move in the tech world by aiming for a fully functional desktop session on RISC-V architecture with the upcoming Ubuntu 25.10 release, dubbed "Questing Quokka." This bold step comes as Canonical plans to drop support for most existing RISC-V hardware due to changes in the required ISA profile family from RVA20 to RVA23.


  • Key Changes: The new RVA23 profile standard will ensure compatibility across RISC-V implementations.
  • RVA23 Capabilities: New features include a hypervisor extension and vector extension for virtualization and math-intensive workloads.
  • Ubuntu 25.10 Benefits: A fully functional Ubuntu desktop session, support for main applications like Firefox and Thunderbird.

What's at Stake

Canonical aims to achieve this milestone by introducing changes in the upcoming Ubuntu release. The new version will include a mechanism to detect if the RISC-V hardware is RVA23 capable or not. Additionally, the built-in Ubuntu upgrader tool won't allow users to upgrade their RISC-V systems beyond Ubuntu 24.04 LTS on hardware that does not support the RVA23U64 profile.

Improving User Experience

Apart from these changes for RISC-V users, Ubuntu 25.10 promises a more polished Wayland experience on NVIDIA GPUs, fully functional Variable Refresh Rate (VRR) support on capable monitors, and improved permission prompting. Enterprise admins will also be able to download autoinstall configuration files directly from Landscape at provisioning time.

A New Era for Ubuntu

Ubuntu 25.10 will feature the upcoming GNOME 49 desktop environment series with a couple of new apps. The beta version is expected on September 18th, while the final release will see the light of day on October 9th, 2025. Canonical's bold move into the RISC-V ecosystem could signal a new era for Ubuntu and its users.

Conclusion

Canonical's decision to raise the bar for RISC-V hardware will undoubtedly lead to faster and more compatible software development in the RISC-V ecosystem. As the industry moves forward with this ambitious plan, we can expect exciting innovations and improvements that will benefit developers and users alike.
