This does not affect a base install of Xubuntu, but one that is shared with other installed sessions that pull in the GNOME Control Center and the Date Time Indicator.
The GNOME Control Center only displays it's configuration tools inside of a GNOME or GNOME-like environment, and will just show up blank anywhere else. To populate these settings, just launch the control center with the below command. env XDG_CURRENT_DESKTOP=GNOME gnome-control-center Moving this bug to indicator-datetime since it could be made aware of the running desktop and gnome-control-center since it seems to be an intentional functionality of the GNOME desktop. ** Also affects: indicator-datetime (Ubuntu) Importance: Undecided Status: New ** Also affects: gnome-control-center (Ubuntu) Importance: Undecided Status: New ** No longer affects: xubuntu-meta (Ubuntu) -- You received this bug notification because you are a member of DX Packages, which is subscribed to indicator-datetime in Ubuntu.
