If this is addressed clearly somewhere else, please let me know and I apologize in advance.

Does anyone use VNC with recent releases of KDE ? I'm using Kubuntu 14.04 / KDE4 with TigerVNC and have been since it came out. Off-and-on for some time, I've attempted to get Kubuntu 15.04 and/or 15.10 working with VNC - not x11vnc, but separate independent servers (eg. <ip>:1). Basic stuff... "vncserver -geometry....options...". I've not been able to get this to work with tightvnc, TurboVNC (with or without virtual GL), TigerVNC, RealVNC, NoMachine, vnc4server (and probably others) on at least 3 different machines. Errors vary between KWin and others crashing complaining about Open GL 2.0 and just black screens or the old X-pattern screens.

I have to admit I don't understand all the graphics extensions required and referenced in other posts on the internet.

I would appreciate someone with direct knowledge and/or experience to help me understand if this should work, and if so, some steps for getting it to work. Specifically, I'd like to get Kubuntu 15.10 working with VNC using normal KDE desktop. If this should work, I can start trying to re-configure a system and present steps/info along the way; however, if it's known not to work, which is what I'm thinking based on other posts I've read, then that's an answer as well...although that leads to the question of will it ever work, and if it's a matter of a VNC distro supporting some new extension.

Anyway, I appreciate any help since I've pretty much gave up and switched to xfce (which works great, but doesn't have the feature set that I like from KDE) for any immediate needs outside of my 14.04 system.

Thanks,
Jeff

tl;dr, use x11vnc.
You're likely either trying (or failing, nvidia) to indirect OpenGL, but that limits to 1.3 whereas QtQuick hard depends on 2.0
