I can't for the life of me figure this out...
I've installed Mint 19 with Cinnamon on VirtualBox 5.2.22 (latest version I believe) and after installation, I then installed VirtualBox guest additions 5.2.22 using Devices -> Insert Guest Additions CD. After rebooting, I'm apparently still running in software rendering mode. My 3D acceleration is enabled and I've given the system 128mb of video memory. I've never been able to get Cinnamon to work in VirtualBox, but I can't figure out what I'm missing... Any suggestions?
Thanks!
