[Interest] Run Qt Widget program with minimal Xorg installation on Linux

[ruslan]

Hello!
My target is to run simple Qt application witch uses Qt Widgets ( not
console app) on remote VPS.
So I installed minimal set of Xorg and also Blackbox to have some simple
WM. To see it I also installed x11vnc.
Up to this point everything work well. I can connect to my VPS with VNC
client and I can run X apps, like xclock.
I installed Qt 5.4 with graphical installer without problem. But while
running a simple test program I get lots of errors:

|QWidget::paintEngine: Should no longer be called
QPainter::begin: Paint device returned engine == 0, type: 1
QWidget::paintEngine: Should no longer be called
QPainter::begin: Paint device returned engine == 0, type: 1
QPainter::save: Painter not active
---
etc., about 100 lines

Ok, I've run the program with -platform linuxfb, activated framebuffer but I still get same errors as below.

What I do wrong or how can I run Qt non console program on remote server?
