Windows 7 x64 Service Pack 1 (w/all current updates) as host, running the guest: Ubuntu 14.10 utopic (Xfce interface, complete Xubuntu) and ofc., there's a *problem* namely after running a update (sudo apt-get update ; sudo apt-get upgrade) which pulled a kernel upgrade effectively disabled (nullified?! not exactly sure - dafuq had happened; I'm quick to post here, w/o taking a look :)) teh VirtualBox Guest Additions (VBoxGuestAdditions_4.3.20.iso) which had been installed.
So, the clipboard AND all of the other features, display, as in the screenshot -everything- is gone!..:(

.. What do you guys do, when it happens?! :)
*reinstall? :-0
P.S.
Numerous times in the past, w/many different versions of, both, VirtualBox and/or Linux: there has never been this kind of a problem.. Until today, gah.
Edit: err, in the screenshot, didn't save / dig up when it happened.. just showing that there are no "issues" within teh Linux.
