[xubuntu-users] Help me understand please

[Daniel Wastak]

Welcome to the world of linux.
gparted is simply telling you it doesn't support encrypted file systems.

On another note I wonder how many more people will switch to linux
once Windows 10 S hits this summer?

I am also a user of xubuntu and chrome-os & loving it.
