Hi guys!

According to the changelog of Qt5.8, vnc is back. I'm currently on Qt5.9 and i was able to launch my application with vnc enable like this:
```
./myQt59app -platform vnc:size=272x480
```
Via my VNC client everything works very well, however i have nothing displayed on the screen of my board :( . Do you have any idea on how to launch a qt5.9 application on a board and have a remote access via VNC ?

Hi,

I'm not sure whether it's possible to have several backends running at the same time. Anyway, you should rather ask that on the interest mailing list. You'll find there Qt's developers/maintainers. This forum is more user oriented.

Hi @SGaist ,

Thanks again for the input. I wasn't sure if it was possible. I will ask anyway to be 100% sure.
If it's not possible, i will stick with my old approach which is to use a separate vncserver (x11vnc).

Thanks.

I am using qt5.9 and i am able to start my qt application with vnc backend.However, when seeing from vncviewer or bnvc on android, i can only see a small part of my applicaiton( 1024x600 for my applicaiton , but on vnc client i can only see 1/4 part of the whole display).
The following is my procedure:
on my embedded linux server, run ./myQt59app -platform vnc:size=1024x600 in terminnal; on andriod ,using vnc viewer or bVNC to listen to ip address and port of my linux device. But both app can only see nearly 1/4 of the whole display.

What is your procedure?Thanks!
