vboxclient the virtualbox kernel service is not running

[0bWAN]

If this appears when you run LL on a real hardware, it is because the script that runs VboxClient, in case when Vbox kernel module isn't detected sends a notification message.
Fix is next:
Run this in terminal (providing a sudo password)

Code:

gksudo leafpad /etc/X11/Xsession.d/98vboxadd-xclient

find the line

Code:

notify-send "VBoxClient: the VirtualBox kernel service is not running.  Exiting."

Now change notify-send to echo

Code:

  echo "VBoxClient: the VirtualBox kernel service is not running.  Exiting."

And save the file.
On next reboot it will not appear again.
