I remember using XDMCP ~20 years ago for this (underpowered machine as thin-client to beefy server, with graphical login). Does LTSP have additional features or better performance?

LTSP 4 uses XDMCP as Login manager and GUI export.

LTSP Clients boot with PXE and get the root filesystem via NFS, then it uses XDMCP login screen.

AFAIK, LTSP 5 uses LDM instead of XDCMP.
