I was busy last days... anyway I got turbovnc from AUR repo (archlinux) now
everything works fine. But I think there is a problem with make install from
the sources codes, because it's not normal that vncserver wasn't where I
expect, and I didn't mess with the sources... and the issues happen on both
computers, and I got the sources independently.
when I asked to how to know the list of displays, I means nomachine use display
:1000 turbovnc :1 virtualgl :0, so I would like to know how many displays are
running on my computer, and what are their ids.
I got sometimes delays with my mouse, I solved this by lowering a bit the image
quality. it's absolutelly not a real problem, but I asked myself if it's
possible to use a mouse directly connected to my headless server in turbovnc,
so having two mouse cursors, one shared between the client and server, second
only in turbovnc
thx

NX doesn't rely on the X11 forwarding capability in sshd. It has its
own method of compressing and then tunneling the X11 command stream, and
architecturally, it is actually a combination of an X11 proxy (which
compresses the X11 stream) and a client-side X server (which takes care
of displaying the decompressed X11 stream.)
From Section 6.3 of the VirtualGL User's Guide:
"The application server’s SSH daemon should have the X11Forwarding
option enabled and the UseLogin option disabled. This is configured in
sshd_config, which is usually located under /etc/ssh."

The default value of VGL_DISPLAY (which is what you're setting with the
vglrun -d switch) is :0.0. Not sure why setting it to :0 wouldn't work,
but it could be a factor of using a headless display.

Not sure what you mean by the "list of displays".
