I don't know about LibreElec specifically, but I have a GMKTek with an N150 running debian and kodi. The kernel is a 6.12.16 (older than the latest libreelec 13) and intel graphics firmware 20241210-1. I'd bet that Libreelec is up to date with these. The N150 GPU on this system has a "newer" pciid than N100 so it needs a new driver that can find it.
