I install xubuntu-desktop
in a fresh ubuntu 14.04 system. When I was using the xubuntu desktop environment, I click "logout" in the top panel and the following dialog appears
But nothing happens after I click "Log Out".
Instead, if I run xfce4-session-logout
from the terminal, another dialog appears (I can't take a screenshot) which allows me to "Log Out" or "Restart" or "Shut Down" or "Suspend". So how could I fix this problem?
