if after see here
https://forum.magicmirror.builders/topic/15778/fix-for-black-screen-in-2-16-and-later

if before do

pm2 stop all
pm2 flush
pm2 start 0
pm2 logs --lines=50

I followed the instructions and have a MM running on my Acer Revo. However, when I start MagicMirror, all I see is a blank screen. I have pm2 and electron installed, where do I find the logfile to try to track down the issue?

Install ubuntu 16.04LTS (internet connection HIGHLY recommended)

You MUST (check box) “Install 3rd Party Drivers” during installation

Fully update the installation via the software manager after installation (It often needs to)

Install node (includes npm) (I use node 8 )

1. curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -

It will ask you if you want to install curl (gives you the command). Do so. Then run #1 again

2. This will complete the installation of node and npm

sudo apt-get install -y nodejs

3. Check for success of node and npm installation in your terminal.

run node -v (this will show your version)
run npm -v (this will show your version)

Now install MM

Run git clone https://github.com/MichMich/MagicMirror.git in your terminal

You may be asked to install git here. Do so. Use the command presented to you in the terminal

Then run git clone https://github.com/MichMich/MagicMirror.git again

Then cd MagicMirror and run npm install

Then run your mirror npm start

Yes, as I said, I too had ubuntu 18.xx and MM up and running. I just prefer NOT to deal with any vulnerabilities which 16.04 doesn’t have. I don’t know of any benefit to running 18.xx over 16.04 and, as I stated, I’m not a fan of the new UI in 18.xx. I ran MM over Windows when I first started. The disadvantages quickly became apparent. Hello-Lucy never would have happened if I didn’t leave Windows behind. I never looked back. :-)

I had version 18.xx installed, up and going just fine on my dev machine

I am used to dealing with vulnerabilities, since I mainly work with Windows

But, I just have my mindset to run npm audit fix --force & npm i lodash@4.17.5 -g & npm i acorn@^6.0.0 -g after every install of MM2. only takes a few minutes extra and it fixes all the vulnerabilities. Except for a few that come with some of the modules. With Ubuntu 18.xx, if I remember, I think just the npm audit fix --force was all I needed to do.

i got ubuntu installed no problem…

i know NOTHING about it so i couldnt even get past how to install the wireless adapter lol…

so im scrapping this and going back to install raspbian on the pc and will try it at that point.

Actually, this is more of a recommendation confirmation. While you can use ubuntu 18.xx and MM together, I don’t recommend it. I just did a clean install of ubuntu 18.04. Newest stable node and npm. MM v2.6.0. Yes, it runs MM but I don’t see any benefit to using ubuntu 18.xx over 16.04 LTS. I don’t like the changes to the UI in 18.xx and I really don’t like dealing with all the vulnerabilities.

Ubuntu 16.04 LTS has a more intuitive UI (IMHO) and there are NO vulnreablilities to deal with. NONE!

So, for the time being, I’m staying with Ubuntu 16.04 LTS. It’s trouble free and MM loves it, too.

I did a test install of Ubuntu 18.04 on a machine I found in someone’s trash. That’s when the vulnerabilities reminded me of why I don’t like 18.xx. Look at the specs. One man’s trash is another man’s treasure.

Sigh. I suppose I can try again. Did you have to do any fiddling to get the OS to use a graphics driver?

No sir. I did a standard install of ubuntu 16.04LTS (I only use this version. I tried 18.xx and had trouble) During the setup of the installation there is a click box for “use third party drivers” or something to that effect. I always click (enable) that option. I don’t know if it’s worth mentioning but I always use a wired internet connection during installation. It’s just faster that way as it updates everything.

Let me know how you make out. :thumbsup:

Intel Atom processor and integrated graphics is not suitable for Ubuntu and therefore the MagicMirror.

The only two laptops that I’ve had trouble with are both ThinkPads. I struggled with them and eventually gave up.

However, I did have success with a little piece of $h1t with specs similar to what you mentioned.

I might put the server version on it and turn it into a gateway or something.

Using MMM-pages and MMM-voice, so a more powerful CPU would be preferred.

That is largely the reason I moved away from the Pi. (I still have my first Pi mirror). I’ve been using MMM-voice and Hello-Lucy for about a year now and I could not be more pleased with the results and the performance.

@mdhenriksen

I have not found heat to be an issue at all. In fact, by removing the motherboard from the case, the temps are actually lower, even when placed behind a mirror. As long as the construction of the mirror is well ventilated, I don’t think that would ever be an issue.

I do not remove the fan. I’ve found that in a normal environment, (people, tv, ambient noises, etc…) the fan noise isn’t even noticeable. Only when the house, or room, is completely silent is the fan audible. For me, this is not an issue when a mobo mirror outperforms any Pi mirror, hands down.

Note: There are silent fans these days but I have never used them with a mirror. I’ve never felt the need to but that is certainly an option for anyone.

Nice to know! Got a old laptop I’m gonna try it with then! Using MMM-pages and MMM-voice, so a more powerful CPU would be preferred.

How do you wake the screen up like a PIR-Sensor does?

I use voice commands with Hello-Lucy to put my displays to sleep and to wake them up. I use this on my Pi mirror. https://github.com/alexyak/motiondetector

Habe you compared the Laptops Power consumption with the raspberries? ;)
For sure it runs way better, but if you use just normal stuff, it is absolute not necessary imho.
Most of us use the mirror on the wall, without tons of cables (execpt Power) viewable. With a Laptop you have to be more tricky.

You’re not just running a raspberry. You’re also powering a display. I have not compared but I am sure there is a nominal difference. If there is a difference, the performance boost outweighs the cost difference.

Normal stuff? There are single modules that the Pi struggles with. I don’t accept stuttering transitions, RAM inadequacies, system overload and heat issues just to use a Pi.

I don’t know how you speak for “most of us”, but ok. Disassemble the laptop. Fits behind mirror as easily as a Pi. Only the power cord showing. How is this different from a Pi mirror? It’s not.

And what are your solutions for GPIO related stuff like temperatur sensor or PIR-Sensor (infrared or radar).
Do you always use the laptop screen or how does this look?

I don’t need a GPIO solution for temperature sensors. My thermostat already tells me that information. PIR sensor for motion? Not necessary. A simple usb webcam will do the trick. You can use the laptop display or you can use an external monitor when the laptop board supports that. I haven’t seen one that doesn’t.
