FOSS - ensuring even new hardware stays in use when vendor-support eventually ends!

Whether or not you install GNU/Linux on it today, your new will eventually lose support. Thanks to the impressive work of project (@AsahiLinux), it will not need to end up in the landfill once it does.


Great to see as the default desktop environment!

You don't need a new computer for up-to-date software ... just the right software!

Come to #Umweltfestival 2024 in #Berlin to learn about the role of independent #FreeSoftware in the sustainable use of hardware.

🗓️ Sunday 28 April, 11-19h
📍 Straße des 17. Juni (Brandenburg Gate)

#KDEEco together with #FSFE (@fsfe) and Bits & Bäume (@bitsundbaeume_berlin) will be there! Some in the #GNOME and #postmarketOS community may be joining as well :)

We will have old, otherwise unsupported #computers and #smartphones for visitors to try, as well as some new ones, all running #FreeSoftware.

The oldest, Dell Latitude D600, would have become #eWaste in 2010. If it were human, today it could legally drink alcohol in the USA ... it is that old and, with a little patience, still quite usable!

Come by to try it out :)

I wonder how software licensing fits into this new EU right-to-repair directive. It seems pretty critical for repairability!

Press release: Right to repair: Making repair easier and more appealing to consumers


"Manufacturers [...] will be prohibited from using contractual clauses, hardware or software techniques that obstruct repairs."

How can we ensure energy data from KEcoLab are stable?

@sthak9 has some ideas.

"Ensuring KEcoLab Stability: Introducing Dedicated CI-Test"


is a KDE tool for measuring software's consumption, but it needs robust testing to ensure stable functionality after code changes. Sarthak presents his work in Season of 2024 implementing dedicated test builds with test scripts.

The power of Free Software: Turning trash into treasure!

The Cape Verdean American Community Development () group has been reviving otherwise-obsolete computers with KDE ().

"The result? Less and more control over the functioning of personal devices. That means not having to buy new when your software becomes unusable over time."

Making way for Wayland in KdeEcoTest!

is an automation and testing tool. It is used for creating usage scenario scripts to measure the consumption of software.

Season of contributor Athul Raj K has added support to the tool. Now it is possible to compare the energy demands of software on Wayland vs. X11!

"Sustainable Software" is a strategic goal for KDE, focusing on minimizing resource consumption and strengthening user autonomy. The aim is to create software that uses fewer natural resources, reduces energy consumption, and promotes user choice and privacy.

Learn how Nitin's exciting work on Selenium-AT-SPI in Season of KDE 2023 () made progress in all 3 of KDE's goals at the blog:


Automated testing is crucial for the continued quality of software. The webdriver automates such tests. Selenium-AT-SPI does the same but for programs.

Over the next few weeks, I'm going to TRY to accurately measure my power consumption doing daily work tasks on my big tower PC, the Steam Deck, and the HP Dev One laptop. (Using a Kill-A-Watt P3).

ALSO? Gaming power consumption comparisons between my desktop PC & the Xbox Series X, both at 4K resolution.

I expect it will be an eye-opening experience and I'll never turn on my tower again.

This will undoubtedly branch off into all kinds of software testing too. YES, I'll record & share data...

@killyourfm @baldpolnareffart

You can follow Engineer Detlef Thoms, who does relevant back-of-the-envelope calculations in the "Sustainable Programming" course (see 04:20–06:10).

Calculate the energy savings, make certain assumptions about use (e.g., how often the savings apply), and multiply out. Given the global nature of software, the numbers scale up very quickly.
