☀️ solarpowered

Custom images based on Fedora Silverblue, made using BlueBuild. This began as a learning project to familiarize myself with atomic OSes and GitHub - it is now my fully functional, primary OS image! :)

Also check out atomic-t480s, a much simpler custom image project I started to support Lenovo Thinkpad T480s users.

solarpowered - for Lenovo T480/s devices

NOTE: This image is subject to deprecation in the upcoming Fedora version update; F44 builds will be the last, and solarpowered will not be getting F45 builds.

Includes the following tools for maximum Lenovo T480/s functionality with 0 layering:

• igt-gpu-tools for monitoring iGPU use
• python-validity (sneexy)
• throttled (abn)
• TLP
• zcfan

This image is shipped with kernel-blu with the v4l2loopback kernel module.

It is highly recommended to run append solarpowered-setup upon installation. This installs TLP-UI Flatpak, configures necessary kernel arguments & local initramfs regeneration, and enables python-validity and zcfan. It is recommended to reboot afterwards.

NOTE: This does not configure throttled, as undervolt stable values differ between machines. For further information about undervolting, refer to the official documentation on throttled.

solarpowered-ex - for Ryzen/AMD computers

Includes the following goodies:

• Gamescope, Lutris, MangoHud and experimental implementation of Steam Gaming Mode
• Beta/Unstable version of Sunshine for game streaming
• Ramalama and ROCM packages
• LACT-libadwaita

This image is shipped with kernel-cachyos-lto with its built-in v4l2loopback and zenergy.

photosphere - for Microsoft Surface (Laptop) devices

Includes the following goodies:

• igt-gpu-tools
• powertop and tuned-utils - powertop2tuned is excellent for bridging powertop and tuned
• howdy-gtk

This image is shipped with the linux-surface kernel with the iptsd kernel module.
