Like chilled-out games? How about incrementals where you keep upgrading through a vast tech-tree and get to clean up various location? Sludgineers is for you. There's a demo available with Linux support for Steam Next Fest and it is really weirdly satisfying.
It has a very simple idea - you go through various locations on your map, to suck up all the sludge using your ridiculously long vacuum. As you clean up you get money, and extra money drops when you uncover certain objects, which you then use in the upgrades menu to go through the tech tree to gather upgrades like: more battery power, more powerful suction, drones and much more.

Game Highlights:
- Fight grime and make it shine!
- Buy upgrades and high-tech tools!
- Transform pollution into profit!
- Cruise the countryside and complete quests!
- Localized into 14 Languages: English, Simplified Chinese, Traditional Chinese, French, German, Italian, Japanese, Korean, Polish, Brazilian Portuguese, Russian, Spanish, Turkish, Ukrainian.
The developer also recently revealed it's going to release on August 25th (although Steam tells me August 26th). See the latest trailer below:

Testing it on Fedora KDE 44 and it works perfectly out of the box. Just a nice little casual game to try.
