The latest ChimeraOS update added support for the ROG Ally. ChimeraOS is a Linux-based operating system built on Steam Big Picture mode similar to Steam Deck’s SteamOS.
Here are the notable changes for the ROG Ally.
CHIMERAOS ROG ALLY CHANGELOG
Audio support (With DSDT Override enabled)
Functional WiFi
Functional face buttons
Functional Bluetooth
Experimental partial TDP control in OpenGamepadUI
Suspend functionality is still a work in progress. We recommend disabling auto suspend on the ROG ally and shutting the unit down after each gaming session.
