I am trying to access Zynthian using the wiki instructions
You also could use VNC on any platform, although it’s slighty complex:
$geometry = “2048x1600”;
# vnc4server
When I write vnc4server I get this message:
-bash: vnc4server: command not found
Why does this happen?
What was the output of apt-get install vnc4server?
Í don’t have the computer with me now but everything was installed no errors.
The problem probably is at zynthian side. Perhaps something is missing because nobody tested VNC connection in last SD images until now 
yes they have. It works for me.
Ups! Jeje! Wonderful! Zynthian beta testing is exhaustive … 
Did you tried with Buster?
Maybe I just need to start fram scratch.
I am also having troubles with using the X11 connection.
The putty window just closes when I ssh onto the Zynthian. I have installed the Xming.
I tried using vncserver instead of vnc4server.
Then I was prompted to make a password.
And a server seems to be running but when I connect to 192.168.1.37 in TightVNC it does not work.
I think the instructions for this on the wiki could be a bit more idiot proof 
root@zynthian:~# vncserver
Cleaning stale pidfile ‘/root/.vnc/zynthian:1.pid’!
New ‘zynthian:1 (root)’ desktop at :1 on machine zynthian
Starting applications specified in /etc/X11/Xvnc-session
Log file is /root/.vnc/zynthian:1.log
Use xtigervncviewer -SecurityTypes VncAuth -passwd /root/.vnc/passwd :1 to conne ct to the VNC server.

When I try to use TightVNC
I’m using putty on Buster Just Fine. are you sure you have X11 Forwarding turned on?
Under SSH, X11 Forwarding? after you set it up did you save the profile?
Yes. Every step.
I see now that everytime I do anything with apt-get It ends with error: timeout so I think my install must be broken.
I will try to reflash the sd tomorrow.
I’ll try and get some version/function table together…
it may be the weekend
Update.
Reflashed the sd.
Updated.
Tried the instructions.

When I try vnc4server
root@zynthian:~# vnc4server
-bash: vnc4server: command not found
Thanks.
MobaXTerm works.
Still cant get vnc4server to work but I guess that doesn’t matter now.
Nice! Perhaps you could add some lines to the wiki. If you want to edit the wiki, i would open an account for you.
Yes absolutely!
Are we talking about remote access to the GUI-UI or a standard X11 session?
For GUI-UI access I like the following:
On the zynhtian run
apt install x11vnc
x11vnc -ncache 10
Then start up a vncviewer to zynthian.local:5900
Reflashed the SD. X11 works now.
Haven’t tried vnc again
