Yeah, in 4.14 it's back in the Power Manager settings (System tab).  Or
at least, that's where the control is to enable locking.

If you're asking how to use xscreensaver specifically (e.g., instead of
Xfce's own locker (new in 4.14)), you can specify a particular locker
using the Xfce settings editor.  (Set /general/LockCommand to whatever
you want; take a look at the /usr/bin/xflock4 script for reference.)

Weird.  I have no idea what's going on there.  I have a VirtualBox VM
with Testing installed (VBoxVGA graphics controller), and the display
looks just fine for me.
