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 ?

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!

Hi,
for me the keyboard worked but the mouse didnt.

export QT_QPA_EGLFS_NO_LIBINPUT=1 export QT_QPA_EVDEV_MOUSE_PARAMETERS=grab=1 export QT_QPA_EVDEV_KEYBOARD_PARAMETERS=grab=1 ./myApp --platform eglfs -plugin evdevmouse:/dev/input/event2

Here is how i start x11vnc:

x11vnc -noipv6 -rawfb /dev/fb0 -geometry 1920x1080 -pipeinput UINPUT:direct_abs=/dev/uinput -dk -dp

I found something here: https://embeddeduse.com/2016/04/01/remote-support-vnc-harvester-terminal/

Maybe that is the only way?

Good news, and thanks for the links. I think I'll be testing that NX stuff soon...

Hi and welcome to devnet,

For the reasoning behind that, you should rather as on the interest mailing list. You'll find there Qt's developers/maintainers. This forum is more user oriented.

Hi ganesh,

Do you plan to bump your version of websocket based VNC on top of official Qt VNC plugin? It would be great because it's a great feature to get rid of any specific software to access embedded screenless device.

And the README also states that

display=<num> VNC display number. Server listens to port 5900 + <num> Default: display=0

That's a very useful feature on hosts that also run a VNC server (e.g. any Mac with screen sharing turned on) and thus already have port 5900 in use. Or simply if you want to be able to run multiple applications over VNC.

This is a quite old topic but what is the current situation for this problem?
