🧠 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."
