[X2Go-User] Problems with Screen Saver in kubuntu 14.04.

[Sergey Savko]

Hi.
In Kubuntu 14.04 does not work native Screen Saver. 
Lock settings are set to 1 minute wait. But after this time, nothing happens. 
The logs written «Xlib: extension" MIT-SCREEN-SAVER "missing on display" ». 
Is it possible to do so would native Screen saver work?
