🧠 Why TinyCore x86_64 can run Lumi (but ARM64 cannot)
TinyCore x86_64 has:
full Mesa + GBM
full DRM/KMS stack
complete GTK3
complete X11 libraries
Electron‑compatible sandboxing
working FUSE (for AppImage)
working debootstrap + gnutar + proot (if needed)
full glibc build environment
TinyCore ARM64 (PiCore) is missing all of these.
Electron apps like Lumi depend heavily on:
libgbm.so.1
libdrm.so.2
libxkbcommon.so.0
libnss3.so
libasound.so.2
GTK3
X11 composite/damage/randr
On x86_64, TinyCore ships all of them as .tcz extensions.
On ARM64, they simply don’t exist."

If you are speaking of the piCore64 16.x repo, most, if not all of those exist.

libgbm is provided by the libEGL extension, no?
