Comment 7 for bug 1748844

Target machins is Ubuntu 16.04:

Linux scadauser-NP3020M3 4.13.0-36-generic #40~16.04.1-Ubuntu SMP Fri Feb 16 23:25:58 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

This problem also affected me after a new qt installation ( I only copied the lib, plugins, qml into target machine's /usr/local/qt5.7 ).

Tring to start hud-service:
./usr/lib/x86_64-linux-gnu/hud/hud-service
Repoted an error like:
... load the Qt platform plugin "minimal"...

But my applicatins started normally.
This was due to the "qt.conf", I copied my qt.conf to /usr/lib/x86_64-linux-gnu/hud/ and the problem was resolved.

qt.conf:
======================
