Measured on a real linuxmintd/mint22-amd64 image and on Ubuntu 24.04. The
package installs on both, which is exactly what makes this easy to miss —
nothing on the box can then produce a stream:
* Cinnamon cannot host a virtual display (Muffin has no RecordVirtual).
* gamescope is absent from 24.04 and cannot be built for it: the tree needs
wayland >= 1.23.1 (has 1.22.0), libinput >= 1.26 (1.25), libavif >= 1.2.1
(1.0.4), pixman >= 0.44 (0.42), plus libdisplay-info2 and libxcb-errors0,
neither of which 24.04 packages at all.
* Switching desktop does not rescue it — 24.04 has KWin 5.27 (floor 6.5.6)
and GNOME Shell 46 (floor 48). Only sway 1.9 is even a candidate.
So the gamescope route documented for Cinnamon holds for LMDE 7 (Debian 13,
verified end to end) but NOT for Linux Mint 22.x — which is every mainstream
Mint until Mint 23 lands on a 26.04 base in December 2026. Both the Debian and
Ubuntu pages now say so, and the Debian page carries a per-edition table.
Also states what Debian 13 itself can drive: GNOME 48.7 and sway 1.10 are above
the floors; its KWin 6.3.6 is below.
