The below steps gave me an auto-starting desktop-effects-tolerant vnc.  I haven’t been able to fine one spot that gives a simple method to getting a working vnc on kubuntu, until now:

Make a backup of the MIT-COOKIE auth file. Having this file will allow x11vnc to run without being root, eliminating much of the configuration headaches involved.

ps wwaux | grep auth

The file will be located in:

/var/run/xauth

In my case it was: /var/run/xauth/A:0-q6mb8o – but NOTE: This name will change frequently.  This is why we need to copy this out in the next step.

Create a new directory in ~/.vnc to store this file:

mkdir ~/.vnc

Copy the MIT-COOKIE file we found above to this location:

sudo cp /var/run/xauth/your_file ~/.vnc

Now install x11vnc:

sudo apt-get install x11vnc

Create a password:

x11vnc -storepasswd YOUR_PWD ~/.vnc/x11vnc.pass

Run x11vnc once:

x11vnc -forever -rfbport 5900 -rfbauth ~/.vnc/x11vnc.pass -o ~/.vnc/x11vnc.log -auth ~/.vnc/your_auth_file -noxdamage -display :0

The -auth switch points to the MIT-cookie auth file, and -noxdamage prevents Compiz from creating additional display issues. I would suggest changing the RFB or listening port to a non-standard one for security reasons.
