无法启动KDE

问题是： 

    /*********************************************

        error setting up inter-process communications for KDE

Could not read network connection list.

/home/xxxxx/.DCOPserver_xxxx_0

please check the DCOPserver program is running.

    *********************************************/

解决方法：

1）  In terminal run the command:
        $ sudo ls ~/.kde -altrh
        $ sudo chown -R username:username ~/.kde
       => Generally, it can solve the problem.

2）

This was fixed by removing the .ICE* Ａnd .DCO* files Ａnd rebooting:

$whoami
bob
$cd /home/bob
$rm *.ICEauthority
$rm *.DCOPServer
$su
# reboot
These files are recreated in next KDE login

3）

 How to see the port of the connection of vnc.

    => vncserver uses tcp port from 5900:

         desktop number: 1 -> 5901

         desktop number: 2 -> 5902

         ....

         so in terminal run next command:

         $ netstat -na | grep 590
