cinnamon-screensaver
"Works and locking the screen is instant on my system. Only downsides are the limited configuration options, the tight intergration with Cinnamon which makes replacing it with something more useful pretty much impossible and lastly, there is no option to switch off the screen (powersave) when the screen is locked."

virtualbox-4.3
"As of LM 19.1 this is a very old old version of Virtualbox; I suggest downloading the latest (6.x) from Oracle. Also to get full USB support you need to add your user to the 'vboxusers' group."
