I have 2 questions for the group, one of which isn't exactly related to GNU and so might need to be moved (we shall see).

1.) I am currently running Debian 10 with the cinnamon desktop environment. I've tinkered with the display settings and such and everything looks sharp and nifty (I love dark mode). The only thing I hate about it is the display manager (I believe it's lightDM). It looks so old and out of place compared to the modern environment it hands off to.

Thus my question is how does one switch this? Has anyone made the change (in debian 10)?

I am also curious if display managers are interchangeable between major distributions (i've seen some nice Arch ones).

2.) Does anyone have any tips and tricks in terms of how to segment a home network?

Like the rest of us, I find myself adding more and more IOT gadgets (including cable company supplied whole home PVR equipment) to my home LAN. And because I have become somewhat security conscious, I don't like the idea of such hardware sharing the same space as my laptop, phone and tablet.
