Skype window problem in Ubuntu 14.04

Skype app in my Ubuntu system work perfectly. But today when I run the app, I see this:

skype window

How Can I fix this?


The following steps have helped other people who had similar issue:

  1. Get the PID of the last process to use the shared memory segment (lpid — should be the last column):

    ipcs -mp|tail
    
  2. Find out what process is that:

    ps aux|grep <lpid>
    

    where <lpid> is the PID of the last process.

  3. Terminate the process either by closing the offending application or executing

    kill <lpid>
