I like Cinnamon, which is odd, because I don't really "like" desktop managers. But when I need a head, I like Cinnamon. The issue I mostly have is Cinnamon doesn't like me. Or rather, VirtulBox, with its ever-present, "Software Rendering" error. I'm putting this as a placeholder because I think I may have finally gotten it to work consistently, and wanted to bookmark it:

1. If running linux as host, install virtualbox-guest-x11

2. Max out guest display memory (128MB)

3. Choose VMSVGA (I read VboxVGA was solely for Windows guests)
