I want to use something like notify-send in a script to pop up on the HDMI screen.
The command is installed, but when you run it remotely it does not do anything. I assume this is because it doesn't know what display to send to (since I'm remote logged in).
what is the DISPLAY:x syntax to get the HDMI display?
I tried a couple common ones but no go
[root@runeaudio ~]# export DISPLAY=0.0
[root@runeaudio ~]# notify-send Test "Hello World"
[root@runeaudio ~]# export DISPLAY=0
[root@runeaudio ~]# export DISPLAY=:0
[root@runeaudio ~]# notify-send Test "Hello World"
[root@runeaudio ~]# export DISPLAY=:0.0
[root@runeaudio ~]# notify-send Test "Hello World"
[root@runeaudio ~]# export DISPLAY=:1
[root@runeaudio ~]# notify-send Test "Hello World"
