@sdetweil I suppose I would look stupid to tell you that at the moment I have not connected my rpi 4b to any display. Could that be answer?
-
@bachoo786 Hm… could be,that would be no display 0 (i hate it when the computers get it right!)
if u want to see it from some other system, then do
cd ~/MagicMirror node serveronlyit will tell you what IP address to put into the browser on your other system
-
@sdetweil right ok make sense.
to be fair the instrcutions on github on installing MagicMirror are little confusing as the installation script asks you if you want to use pm2 and when you say yes it should automatically run magicmirror via pm2.
however there is this link (https://github.com/MichMich/MagicMirror/wiki/Auto-Starting-MagicMirror) on the github explaining how to auto starting the magic mirror. And when you follow this link you end up having two instances of magic mirror on pm2 i.e. MagicMirror and mm. Thats confusing!
Do I still have to follow the autostarting magicmirror link? or is the install script sufficient?
-
@bachoo786 install script does it for you…
-
@bachoo786 could you do me a favor before u plug in a monitor,
can you do
pgrep Xorgfrom the ssh terminal…
I’m guessing it should return nothing…
my new run-start.sh script in next release, will detect text mode and start your installation in serveronly automagically.,! (pm2 just starts the script)
-
@sdetweil yeah it returned nothing.
so shall I follow your script i.e. https://forum.magicmirror.builders/topic/10171/anyone-want-to-try-updated-installer
and reinstall MagicMirror?Do I have to worry about installing pm2? will Magic Mirror run automatically if I was to reboot my raspberry? etc?
to be fair I want to install and run Magic Mirror on my raspberry. I suppose that is server mode? and not client mode? whats the difference sorry ?
-
@bachoo786 you don’t need to reinstall… you are ok… just need a display on the 4 or run server only…
the new code isn’t used on my install except for pi0, which won’t work anymore without some changes

yeah it returned nothing.
awesome! thanks
-
@sdetweil what is server mode and client mode? I dont understand the difference. Can you please explain? thanks.

the current installation only tries to run on the real display… YOU have to figure it out otherwise…
(which we are doing here in this topic) -
@sdetweil I am really confused buddy.
lets start again please. I install mm using the script, what do I do next? do I need to worry about pm2? I suppose installing using the script installs MM as the server on the raspberry pi?
-
@bachoo786 sure…
MagicMirror is a web application.
it can be run in two different models
-
the browser and ‘web server’ are the same app, on the same machine
other machines can access the ‘web server’ part too -
the mirror is run without a display (server only), and some browser somewhere is used to
access the ‘web server’
you might do 2 where u want to provide Mirror access to multiple systems but don’t need it where the pi is installed…

ok makes sense. I normally access the mirror by port forwarding my raspberry pi on port 8080 and thats how I can access it on different machines or at work. And I like it that way to be fair. Because eventually my raspberry pi 4 will be inside the 2 way mirror running the Magic Mirror software.
-
@bachoo786 there is only one install…
but two ways to run…
but if u don’t have a display, then u are forced into serveronly mode
from the readme
https://github.com/MichMich/MagicMirror#server-only
from manual installation
https://github.com/MichMich/MagicMirror#manual-installationManual Installation Download and install the latest Node.js version: curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash - sudo apt install -y nodejs Clone the repository and check out the master branch: git clone https://github.com/MichMich/MagicMirror Enter the repository: cd MagicMirror/ Install and run the app with: npm install && npm start For Server Only use: npm install && node serveronly . // < ------- -

well, in that model, typically, u have both server and browser running on same machine (pi 4) inside the actual mirror enclosure on the wall), so NOT serveronly mode
see the forum section https://forum.magicmirror.builders/category/12/show-your-mirror
where people are showing their implementations, with the whole setup -
@sdetweil ok so I will install like everyone else i.e. server and browser on the same machine. Thanks for sorting my head on that.
Now with regards to the install script I do not need to follow this link (https://github.com/MichMich/MagicMirror/wiki/Auto-Starting-MagicMirror) to autostart magicmirror? as you said thats all taken care in the install script? Am i correct? or?
-
@bachoo786 no… u have pm2 which does it all… (oops, the default run-start.sh script ONLY starts in both mode, YOU have to change it to do serveronly like below)
u have already installed both… again there is only ONE install process, but two ways to run
today
issue the following commands (either set)
run bothcd ~/MagicMirror npm startor
run serveronlycd ~/MagicMirror node serveronly -
@sdetweil ok I will try it when I get home mate. Thanks.
-
@sdetweil hi quick question… so i connected my raspberry pi 4 4gb to hdmi o but there is no display ? do i need to do some settings? my raspberry pi doesnt display anything? is that normal for raspberry pi 4?
-
@bachoo786 i don’t know what you need to do to enable the display after booting into text mode…
maybe run raspiconfig. and select boot to desktop?
