Remote desktop Sharing in Ubuntu 14.04

Ubuntu 14.04 te aşağıdaki gibi vnc-viewer hatası alıyorsanız;  Vino require-encryption false yapmanız gerekebilir.

java.io.IOException: No security type suitable for RFB 3.3 supported

 you must to do step step in below

$ pkill vino
$ export DISPLAY=:0.0
$ /usr/lib/vino/vino-server &

still not working
after short investigation:

gsettings set org.gnome.Vino require-encryption false

now it`s work but i need it permanently  :))

Looks like something wrong with default gui Lets install something else like dconf



sudo apt-get install dconf-tools
finally: dconf > desktop > gnome > remote-access > enabled - uncheck !!!
issue fixed.
Remote Desktop sharing working after reboot !!!
Maybe i use not correct way but to somebody it`s can be useful.:)

thanks :) good luck
