I'm using a USB Bluetooth dongle on my Raspberry Pi. So far I managed to connect the device and pair it using the terminal. Yet the desktop/GUI Bluetooth manager won't open. I can see the icon on the desktop and as you can see it I can even right-click it for options but none of them open. I've tried everything described here with no success. Any ideas why does this happen and how could I fix it?UPDATE: following @Patrick's suggestion I did a pkill blueman-applet and blueman-applet and got the following output: pi@raspberrypi ~ $ pkill blueman-appletpi@raspberrypi ~ $ blueman-appletXlib:  extension RANDR missing on display :1.0.Loading configuration pluginsblueman-applet version 1.22 startingUsing gconf config backend_________Load
