+## Plasma Bigscreen 
+Plasma Bigscreen has issues when started directly, so we're launching a normal plasma session first  
+`$ dbus-run-session startplasma-wayland`  
+Then we can replace that with the bigscreen session  
+`$ plasmashell --replace -p org.kde.plasma.mycroft.bigscreen`  
+
+## Launching Plasma and Bigscreen
+Put this in `.bash_profile`  
+```
+if [[ -z $DISPLAY ]] && [[ $(tty) = /dev/tty1 ]]; then
+	dbus-run-session startplasma-wayland
+fi
+```
+
+Create a script that launches bigscreen  
+```
+#!/usr/bin/env bash
+
+plasmashell --replace -p org.kde.plasma.mycroft.bigscreen
+```
+Add the script to "Autostart" in the settings. Make sure executable is set
