+[`bpytop`](https://github.com/aristocratos/bpytop) is a great little resource monitor. I have a server with a small display that doesn't do much but show a login screen all day, and I figured why not just have the display run a resource monitor?

+
+
+### Method 1: Direct to the VT
+
+You can launch any program directly to the VT and skip the X server or Wayland compositor nonsense. However, keep in mind that the VT can be pretty limited when it comes to the features we expect from a modern terminal program.
+
+Regardless, here's how to configure `greetd` to do that:
+
+`/etc/greetd/config.toml`:
 ```toml
-[terminal]
-# The VT to run the greeter on. Can be "next", "current" or a number
-# designating the VT.
-vt = 1
-
-# The default session, also known as the greeter.
 [default_session]
+command = "bpytop"
+user = "thurstylark"
+```
 
-# `agreety` is the bundled agetty/login-lookalike. You can replace `/bin/sh`
+### Method 2: Using `fbterm`
-# with whatever you want started, such as `sway`.
-#command = "agreety --cmd /bin/sh"
 
-#command = "fbterm -- bpytop"
+[`fbterm`](https://wiki.archlinux.org/title/Fbterm) is a **f**rame **b**uffer **term**inal emulator which basically boils down to being a better VT.
+
+`/etc/greetd/config.toml`:
+```toml
+[default_session]
+command = "fbterm -- bpytop"
+user = "thurstylark"
+```
+
+This should give you more flexibility with font sizing and configuration through `fbterm`'s [configuration file](https://wiki.archlinux.org/title/Fbterm#Configuration_file).
+
+
+### Method 3: Using `cage` and a graphical terminal emulator
+
+This will be less performant than the other methods, but will afford you many more features. This is the method I actually use for this use-case.
+
+`/etc/greetd/config.toml`:
+```toml
+[default_session]
 command = "cage -s -- alacritty -e bpytop"
-
-# The user to run the command as. The privileges this user must have depends
-# on the greeter. A graphical greeter may for example require the user to be
-# in the `video` group.
 user = "thurstylark"
 
 ```
