Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

I have enterprise location where i have used x11vnc, remotely i used Gtk vnc client or the default ubuntu remote desktop client.

Its a nightmare after 1 minute, the whole system get frozen and i cant do ssh nor remote access anything at all. Only power off and power on is the way.

I badly need one stable low quality , low bandwidth not crisp and clear VNC server, client tool for Linux.

Which one i can use? Or am i using the x11vnc configuration not correctly which is causing the server to crash?

ex.: start the server when system boots:


export DISPLAY=:0.0
p=$(ps aux | grep x11vnc | grep -v "grep" | awk '{print $2}' )
if [ $p ]; then
  echo "running..."
  x11vnc -forever -passwd wecanbeALIVEforeverifVNCis &

xterm &




open source, i can work on it

The fact that you can't even ssh in suggests it is more than x11vnc crashing, maybe even a kernel panic. I've had issues in the past with buggy display drivers allowing X11 and X11 programs to crash the computer. Have you tried using vncserver, part of tightvnc? This won't share the already running display, but creates a new one in the background that users can connect to. AFAIK, it doesn't use the video card. –  wingedsubmariner Sep 18 '13 at 13:30
