I have solved the problem, using a workaround. The problem is caused by the fact that I am running the terminal as a root. In ubuntu, it is no good to run GUI application as a root, sudo. Reference to https://ubuntuforums.org/showthread.p... Thus, the solution is quite simple, just change to the common user, and it works!
