VNC connection fails: vino<->vinagre

Hello,
I cannot get a vnc connection to my headless PC over the home network. I'm trying to connect from Linux Mint Petra w/ Cinnamon, while the headless box has LMDE w/ Mate, I've been trying this for a while, but it hasn't worked yet unless I connect the LMDE box to a screen and enable vnc connections from its own desktop.
I have vino installed on LMDE, and I can connect to it using vinagre on the client side, but I just see a black rectangle in the vinagre screen, that's it. As soon as I make the connection, I get a pop-up that says a remote computer is trying to get access to my desktop. I don't get to allow or deny though, the pop-up just disappears if I click it, the vnc screen stays black.
Here is some output from vino:

Code:

 ~ $ /usr/lib/vino/vino-server

The way I understand is that you need to by default enable a connection for every connection attempt. So that means starting vino each time from that machine.

Try setting a default password for vino using

Code:

vino-password

Then restart the service and see what happens. I have not tried vino yet. I use tigervnc, so far that has not given me the issues that you describe.

it says

Code:

vino-password: command not found

Also I don't understand how setting a password is going to make it accept connections by default if it's not accepting them without a password. could you explain that some more?

Because vino has quite a few bugs and a few people on mailing lists have mentioned issues similar to yours. Many of them managed to run that command and had success connecting after that.

That is just something I thought may be worth trying.

Hi

I was also struggeling with vino on Linux Mint. Then I found this guide:

The x11vnc way workds great.

this is incredibly frustrating.
I did what was described there (http://forums.linuxmint.com/viewtopi...f=157&t=109097), i.e. I added that line at the end of /etc/mdm/Init/Default, so now it looks like this:

Code:

#!/bin/sh
# Stolen from the debian kdm setup, aren't I sneaky
# Plus a lot of fun stuff added
#  -George

PATH=/usr/bin:$PATH
OLD_IFS=$IFS

mdmwhich () {
  COMMAND="$1"
  OUTPUT=
  IFS=:
  for dir in $PATH
  do
    if test -x "$dir/$COMMAND" ; then
      if test "x$OUTPUT" = "x" ; then
        OUTPUT="$dir/$COMMAND"
      fi
    fi
  done
  IFS=$OLD_IFS 
  echo "$OUTPUT"
}

sysresources=/etc/X11/Xresources

# merge in defaults
if [ -f "$sysresources" ]; then
    xrdb -merge "$sysresources"
fi

sysmodmap=/etc/X11/Xmodmap

XMODMAP=`mdmwhich xmodmap`
if [ "x$XMODMAP" != "x" ] ; then
  if [ -f $sysmodmap ]; then
    $XMODMAP $sysmodmap
  fi
fi

nohup x11vnc -shared -no6 -forever -nolookup -auth /var/lib/mdm/:0.Xauth -passwd ‘Test123!’ 2>/dev/null 1>&2 &

exit 0

well, nothing. I'm trying to connect vinagre, I get "connection to 10.0.0.18 was closed", not even any output in terminal. I think this system just hates me.
