[Feature request] Atomic mode-setting #135
Description
Atomic Mode Setting (AMS) is a mechanism that allows all display settings (resolution, refresh rate, etc.) to be applied simultaneously and atomically (as a single unit), without flickering or artifacts.
Advantages:
- Smooth changes – There are no intermediate states (like in X11), the screen does not flicker when changing resolution or mode.
- Fault tolerance – If the settings are incompatible, the system will simply reject them, rather than going to a black screen.
- Flexibility – You can change several parameters in one request (for example, resolution + refresh rate + rotation).
- Better synchronization – Wayland and the GPU driver agree on changes before applying.
