Wayland vs X11 on AcreetionOS

Short version: X11 is the default and works everywhere today; Wayland support exists for the curious.

What’s what

	Reality check
X11	The 1987 protocol that still runs most Linux desktops. Rock-solid, universally compatible, compositing handled by Muffin.
Wayland	Modern replacement protocol: better security isolation, smoother multi-monitor fractional scaling, tear-free by design. Cinnamon’s implementation is present but marked experimental upstream.

Reality check

X11

The 1987 protocol that still runs most Linux desktops. Rock-solid, universally compatible, compositing handled by Muffin.

Wayland

Modern replacement protocol: better security isolation, smoother multi-monitor fractional scaling, tear-free by design. Cinnamon’s implementation is present but marked experimental upstream.

Trying Wayland

If your session manager offers "Cinnamon (Wayland)" at the login screen (gear icon), pick it for a test drive. For NVIDIA cards first enable modesetting per NVIDIA Drivers.

Log out/in to switch back anytime.

Choosing X11 (still sensible when…)

NVIDIA proprietary driver without recent modeset config.
You depend on apps doing screen capture/input injection the old way (some remote-desktop, macro tools).
Fractional-scaling quirks annoy you less than Wayland’s current gaps in Cinnamon.

Checking where you are

echo $XDG_SESSION_TYPE        # x11 or wayland
cinnamon --version

Screen sharing in browsers, per-monitor scaling, and input latency all differ between sessions — test YOUR workload, not benchmarks.

The trajectory

Upstream Cinnamon keeps landing Wayland pieces each release. AcreetionOS follows upstream defaults rather than forcing experiments — you’ll get Wayland-by-default exactly when it stops being brave.
