x11vnc gives weird errors

TB2 · 2008-02-14 16:18:01

Hi,

I've been trying to get x11vnc working on my other box but if I start it I get weird errors, and I can't find anything on google about this, as many other things are causing these kinds of errors, while no results turn up if I add x11vnc to the search parameters...

Here's the output:

vncserver (for virtual screens :1 and such) is working well btw and there is no firewall installed on that box. It's a twinview setup if that matters. I have no idea what's wrong...

Any idea?

To run x11vnc from ssh session you either have to "su" to root or run x11vnc from local console.

AFAIK shared memory access from different virtual terminal is disabled by default so you have to have root priviliges to access it.

Sorry this bit of necromancy, but i've searched the net about this problem and could't find any specific pointers so now hopefully google will find this solution

did you try running without the -rfbauth option?

also, this page is my x11vnc bible http://www.karlrunge.com/x11vnc/
it has all you ever wanted to know. try some of the things there.
