The big problem with Plos in VMWare is the installation of guest additions. So you can't use full screen or drag and drop, or copy paste from host to vm or the other way. around. However...
Texstar has solve this problem for people using VirtualBox. After installing Plos as a guest in VBox, you can go here:
Menu -> Configuration -> Install Vbox GuestAdditions
Then everything works, with a click of the mouse you might say.
The first log in poses an interesting puzzle by the way. It's bizarre to me, but they seem to like it. Write if you're stuck.
Thanks Buster, that is good info.
I may have a go at trying that out. :-)
I am stuck on the Localhost login! Nothing I input gets me past this point. :-(
Is this what you're looking for?

Bill, concerning guest additions for VB, consider something like this for say Peppermint guest:
"However, Ubuntu has its own dedicated Ubuntu-specific Guest Addon package(s)...
named virtualbox-ose-guest-dkms and ..-x11 and ..-utils . " So it looks like maybe 3 programs.
Get from Synaptic, then reboot, then try drag and drop. May of course be your crappy Lubuntu OS. :)
So Bill I found a 1 TB hd sitting in the junk room that had an old Mint in perfect condition. Last used about Jan, 2017. Ran it. Got PCLinuxOS iso and put it into VB. NO GRAPHICS!!! Same as your problem. Tired of this. Got rid of iso and uninstalled VirtualBox. Upgraded easily to Mint 19.1.
Life's too short for the pain I get with Plos.
