so i have all my modules in place and the system crashes: unable to handle kernel null pointer dereference at virtual address
I’ll roll back to your setup and see if it is stable. i am using calendar, weather, clock and newsfeed- very similar to yours.

Please report if you could stabilize your system. I also had crashes (approx twice a day) when using Chromium. I didn’t had time to investigate the exact cause (to heavy load?).

@Andrius-ok Thanks for the image. This works fine. Have you had any succes trying to upgrade Magic mirror? Noticed this image was running a older version.

Andrius ok

@Hawking my MM with this image on Raspberry Pi Zero W working a half a year without crashing, restarting etc., what modules do you using? Did you try only with my modules? You have to know that SBC is very slow and poor on performance so my modules which is in img is taking 99% CPU always, if tou trying to add one more module I think it’s too much

Andrius ok

@lasharor yes of course, no problems? Did you? Having issues?

Hi @lasharor , my apologies. Yes I have forgotten, very sorry was on long vacation.
So there is my MM image with Chromium for Raspberry Pi Zero W

note: you have to configure WiFi by yoursefl and also all modules to work properly in Yours language.

Thanks! Worked nice, until I updated and Chromium 56 (or so) got installed.
That version can’t connect (for whatever reason) connect to http://localhost:8080/.
Because of this, I had to change the file /home/pi/startMirror.sh and replace the word localhost with the word 127.0.0.1 and reboot.
Now it’s working again :)

Next thing I’m going to try is to update the MagicMirror installation.
Thanks for your image!

I used your image and works quite well, only one issue.
The server doesn’t star till I SSH it.
What I’m saying the Pi Zero W boots and keeps on the prompt but doesn’t start the magic mirror till I ssh the Pi.
Any hints?

Great tutorial but when I booted up my pi I got this:

-bash: xset: command not found
-bash: xset: command not found
-bash: xset: command not found
-bash: midori: command not found
pi@raspberrypi:~ $ matchbox: can’t open display! check your DISPLAY variable.

I do not know what to do to fix this.

Hey!
Try this link to a disc image from Andrius:

Works amazing for me, and I’m sure for you too!

Cheers

@Mikgabo Should I flash this to the SD card on my pi?

Mikgabo

@greenwaydev
I did, worked great for me.

greenwaydev

Awesome! Last question. Do I have to remove the other things I have put on the SD card in my pi? Like everything other than raspbian and jessie? Im kind of new to this stuff

Mikgabo

@greenwaydev
So what I did was format the sd card and use win32 disc imager to flash the sd card, put it my my Pi Zero and it worked.
After install I got rid of some stuff via the config file as I didn’t want all that stuff on my MM.
Cheers!

Changed the display_rotate setting back to 0 but the display is still turned. Any suggestions?

Mikgabo

@greenwaydev
Did you reboot?

greenwaydev

@Mikgabo I unplugged the pi, removed the SD, and changed the rotate setting. Then, I put it back in and plugged the pi back in.

Mikgabo

@greenwaydev I’m thinking you aren’t making the adjustment in the right location (possibly).

Try this from terminal:

sudo nano /boot/config.txt

and add the following to the file. Where you add it doesn’t really matter:

# Rotate display virtically
display_rotate=0

Mikgabo

@greenwaydev After you insert that text save it by ctrl + x, then y and enter

Mikgabo

the type the command:

sudo reboot

@greenwaydev Here is a great tutorial that can help you learn your way around MM.
https://forum.magicmirror.builders/topic/236/complete-setup-tutorial/6

I would recommend, once you get your MM configured the way you like to make a back up of it using win32 disk imager (make sure .img is on the end of the file or it won’t save as a disc image). That way if you mess up your SD card somehow you have a back up to use.
