Using the preinstalled vnc server was created by SebastianM
Good morning everyone!
I am new to linux(cnc), but I am making progress :)
The next item on my todo list is to setup a VNC server on my cnc machine. 

I read that linuxcnc 2.9.3 (or debian12) has a pre-installed vncserver (x11vnc?). Would you recommend this one over tigervnc etc?
And if so.... could someone tell me how to use it?
Simply connecting to that machine from another vnc client doesnt work out of the box.

Regards
Sebastian

I'm not too sure if that's the case, would be interesting to see the source of that info.
Your best bet would be to search for setting up a vnc server on Debian, ignore any AI generated answers.
For reference the Linuxcnc ISO is just a normal Debian one that has been customised with a realtime kernel and the required Linuxcnc packages, so basically any info that pertains to Debian is relevant.
There maybe some threads but you would have to really look for them.
Mind tho it's not the best of ideas to operate an unattended machine via vnc. In fact I feel it's not the best of ideas to leave a home built CNC machine running unattended, this also applies to something you may buy at the very lower end of the spectrum.
From memory, vnc won't let you be logged in at the machine and log in remotely, or it maybe tiger.

I recall there was chat about including it, i was against it as it is a huge security risk and not required for machine control.

If it is included, it does require setting up the password for VNC explicitly, at least it did 10 or more years back.

this post says that vnc is preinstalled.

however - thx for your feedback, I will just manually install one.

Yeah I'd take what that user says with a grain of salt, unfortunately he can be a little unreliable or completely off the mark.

Try this command to see what is installed
dpkg -l | grep vnc
