I've got a desktop computer and a laptop, both running Ubuntu 14.04. The desktop has x11vnc installed on it and my laptop has Remmina. My desktop also has SSH running on it.

I want to use Remmina to connect via VNC to my Desktop computer. I use to have the command x11vnc -usepw -forever set to run on startup, but I disabled it. Now I want to set it to run on startup again. Here is the problem though: when I use SSH to run x11vnc -usepw -forever, I get an interesting error on the computer running x11vnc (what I want to connect to). The error is below. P.S. My laptop's IP address is 10.0.0.7.

  • why not to connect via vncviewer: sudo apt-get install ssvnc ? Jul 15, 2014 at 5:10
  • How well does that work with Xubuntu? Besides, I need something that is easy to configure, although I guess it is time to switch. I have had lots of problems with x11vnc. I will look into it.

  • As it turns out, it was a problem with my VNC client! Problem solved.

In the faq http://www.karlrunge.com/x11vnc/faq.html#faq it states, that the vnc client must have the same colordepth as x11vnc

This helped for me.
