Error with QT over VNC/X11 - Shb - 13.07.2017

Hybrid Version: 2017.05.06.1 (Ubuntu 16.04 64bit)
What Happens: Program never launches. A splash screen is displayed and then it crashes.
Reproduction:

Install via the guide on djcj's post as usual, nothing out of the ordinary
Install vnc4server and xfce4 through apt-get
Start vnc server and connect
Run Hybrid.

Log has been attached.
It appears as though QT is the issue, maybe you can shed some light or have some experience.
I have tried launching it through Xming with similar results.

Okay, that's a new one seems like qt loses the connection to X.
Will try to look into this some more after work.
(will report back once I know more and/or can reproduce the issue.)

Is there a short&fast way to get vnc4server running so I can connect to it from extern?
(don't use it normally and not keen tinkering with it a lot)
Default configuration doesn't seem to do the trick.
I ran 'apt-get install vnc4server' and then started a vnc client on another machine to connect to the server but connection was denied from the host computer,...
-> so if you got a quick guide to get it running it would help me, otherwise this will have to wait until I find the time to read up on how to set up vnc4server properly,.. (may be this or next weekend)
Seems like there are some issues with vnc4server and kubunu, I will have to test this on another VM,..

Ps.: Is a monitor attached to your system? (iirc there were some issues with qt if no monitor is attached,..)
PPs.: On Windows I know Teamviewer works fine,..
PPPs.: got a vnc connection, but I only see a gray screen,..

Managed to reproduce the issue, but no clue how to taggle the issue atm.
-> will try to look into it over the weekend

RE: Error with QT over VNC/X11 - Selur - 13.07.2017

Using:

vncserver

I get:

Unsupported screen format: depth: 16, red_mask: 3f, blue_mask: f800

Using RGB16 fallback, if this works your X11 server is reporting a bad screen format.

The X11 connection broke (error 1). Did the x11 server die?

using:

vncserver -depth 24

I just get:

The X11 connection broke (error 1). Did the x11 server die?

but no clue why.

-> no clue how to handle this seems like there is some incompatibilty with vnc and Qt.

Yeah, I had the same error message as well, we're basically at the same spot at this point :/ I'll see if TeamViewer works better for me.

Do that an please report back. (I'll also try over the weekend if using a newer Qt version helps, what is the Qt version installed on your system?)

I was having some issues with Teamviewer, not totally sure what.
i have Qt 5.9.1 installed to ~/Qt, but it looks like when Hybrid installs it packages its own Qt dlls (using Wine I assume?) in ~/.hybrid-bin/:

The dlls are for the avsViewer and some other small avisynth related tools.
