No, x0vncserver is something you run in your existing Xorg session. It
will make your local display available via VNC as well.

A friend tried to view my screen this afternoon.

I have Fedora and started x0vncserver PasswordFile=~/.vnc/passwd 

 Geometry:    Desktop geometry is set to 3840x2160+0+0

 XDesktop:    Using evdev codemap

 XDesktop:    

 XDesktop:    XTest extension present - version 2.2

 XDesktop:    RANDR extension not present

 XDesktop:    Will not be able to handle session resize

 Main:        Listening on port 5900

Then from windows tigervnc client, he connects and enters password, and actually controls my display:

Sat Mar  7 19:02:53 2020

 Connections: accepted: <remoteIP::clientPort>

 SConnection: Client needs protocol version 3.8

 SConnection: Client requests security type VeNCrypt(19)

 SVeNCrypt:   Client requests security type TLSVnc (258)

Sat Mar  7 19:03:01 2020

 XDesktop:    Enabling 8 buttons of X pointer device

 XDesktop:    Allocated shared memory image

 VNCSConnST:  Server default pixel format depth 24 (32bpp) little-endian rgb888

But ultimately, after between 5s and 30s, the connection goes down

X connection to :0 broken (explicit kill or server shutdown).

What processes should I see running on my box?

How can we troubleshoot?

We've seen something similar here:

https://github.com/TigerVNC/tigervnc/issues/869

Unfortunately we've not been able to pinpoint what is causing it.

It's just the one process, "x0vncserver".

Not sure. We need to figure out what is triggering it in order to
pinpoint the root cause. So if you can experiment and see if you can
figure out some clues then that would be helpful.

Is there some debugging flags either of my Xorg server or of x0vncserver to help with this?

For x0vncserver you can specify: -Log *:stderr:100

I'm not sure how to enable full logging for Xorg. I know they have a
"-verbose" flag, but I'm not sure of the details.
