Watching movies on VLC i noticed that every some minutes the video hanged for some seconds. I found that a process called "/usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none" was using every 10 minutes for some seconds 50% of CPU making my weak CPU (atom N450) not capable to execute both processes together and video hang for some seconds every time. together with this process, another process called "xfce4-settings-helper" uses 10-15% of cpu. after some seconds both are going to idle.
