# The compositor `emu` starts when this machine has no display, so that the

# Nothing here is meant to be looked at; there is no screen. The point is
# Xwayland: the emulator's `-gpu host` renderer speaks GLX, and with no
# DISPLAY at all it falls back to a software rasteriser. Xwayland's GLX is
# backed by this VM's virtio-gpu render node, so the guest's GLES ends up on
# the host's real GPU.
#
# `xwayland force` starts it immediately rather than at the first X client,
# so `emu` can read DISPLAY out of a running compositor instead of racing it.
