If you’re an avid gamer who adores the look of GNOME’s Adwaita theme you’ll be stoked to hear there’s an unofficial Adwaita theme for the Steam Linux client.
It’s called (no surprises) ‘Adwaita for Steam‘ and, by and large, it does exactly what you’d think: it makes Valve’s Steam client for Linux look more like a native GTK app.
Steam sports a dark appearance by default so this 3rd-party skin is also dark. There are no plans to create a light version (sadly; I’m curious to see what it’d look like “light”).
Installing Adwaita for Steam isn’t difficult.
There’s an installer script (which enables you to adjust a few variables prior to installtion) that you run from the command line.
Alternatively, you can install the skin manually by download the package from Github and extracting the Adwaita Stream theme folder to ~/.local/share/Steam/skins. You then restart Steam and select the Adwaita skin from Settings > Interface.
But if you don’t want to fuss around with commands or manually moving folders you don’t have to.
You can get the Adwaita Steam theme on Flathub by way of a GUI installer.
This package isn’t by the author of the skin but it will check for and install updates to the Adwaita Steam theme when they’re released (since Steam client updates from Valve may introduce changes the skin has to keep pace with).
Want to try it? Install the app from Flathub, launch it, follow the prompts, and then select the Adwaita skin in Steam as mentioned above. Launch Steam and hey presto: Adwaita Steam mode unlocked.
To complete the look it’s recommend to install and enable the rounded window corners GNOME extension I wrote about a few months ago. This ensures you get the appropriate border radii around the Steam window for an even-more integrated vibe.
Finally, you may wish to install the Cantrell fonts (the default GNOME UI font) to complete the look.
