one interesting thing I learned this week, LXC 'VMs' on Proxmox do not have an emulated graphics card, so if you install a desktop environment on one, you need to connect to it using something like #NoMachine.

I've been using NoMachine for years at this point, ever since the bitrot in #X2Go got too bad to ignore. it works quite well, apart from some annoying minor bugs with grabbing keyboard input on Cinnamon.
