So I've tried to make our screen-broken HP laptop to also serve as LTSP Server in addition to various other tasks, without luck, which may be cuz I'm running LM10 LXDE while the instructions are for Ubuntu. Excuse my ignorance.

The entire output from Terminal after installing LTSP stuff along with a Server kernel and a load of other packages:
