Not sure how to do that.

Plug it in and use it?
What exactly is the problem?

No reason other than not aware that there is a "arandr" tool.

Not sure how I would have found that out,

You did not have to know that.
On the Rapbian Desktop it's in the Preferences menu as 'Screen preferences', exactly where you would expect a tool for screen manipulation...

I have installed a working system 3+ years ago but used MYSQL 5.5 or what ever at the time. From memory, everything worked straight off.

Unlikely. AFAIK the default on both is that they only accept local connections. And it has been for a long time...
Google for 'bind address'

Using Wifi or wired network?
There are some known problems with Wifi and HDMI 'interactions'.

This is a lsusb dump of all my connected USB devices. I have bolded the line with the USB bridge device. We can see that the chipset is ASM1153E I'm struggling to see the purpose of your post... And is there a reason to use purplish/red text? Looks quite aggressive to me. Also can't see any bold te...

In the default Raspbian install, sources.list and sources.list.d/raspi.conf are identical. Don't think so (and I assume you mean 'raspi.list', not 'raspi.conf') I have not made any changes to them: pi@raspi4b:~$ cat /etc/apt/sources.list deb http://raspbian.raspberrypi.org/raspbian/ buster main con...

Sources.list.d seems free of garbage : deb http://archive.raspberrypi.org/debian/ buster main ui staging # Uncomment line below then 'apt-get update' to enable 'apt-get source' #deb-src http://archive.raspberrypi.org/debian/ stretch main ui <snip> W: Le fichier configuré « staging/binary-armhf/Pack...

so the question is, how do I publish to the mosquitto server on the Pi from another device like an ESP32, and also how would I subscribe using an ESP32 Use one of the ESP32 programming tools + MQTT library. This can be done with e.g. MicroPython. This is *not* a Raspberry Pi issue and I would googl...

Use the -h parm. default is localhost. e.g mosquitto_pub -h 192.168.1.2 -t topic -m message.

Why can't you use dhcpcd.conf?

Which OS + version does your Pi run on? python3-openpyxl seems to be available on Debian/Raspbian Stretch and later (not on Jessie) And did you do an update before trying to install the package? The problem with the pip command could be that you run a version of pip / setuptools that's too old. That...

Is anyone from the foundation reading this?

They probably do... at some point. Keep in mind it's the holiday season...
Even the RPF/RPT people should be allowed the odd day off

It is very hard and time consuming when I reformat and have to update the Pi to the latest version which takes around 30 minutes for me

Do it once and create a backup. Use the backup when you want to make a fresh start.

The program is coded with python, If this is not the Right place please tell me where to post it.
Thanks

Why does it need compiling if it's written in Python?

Almost certainly. But because you give no relevant information apart from the Pi model it's impossible to say what that 'something; is...

How is this related to Python?

For a GUI version on each pi (easier to troubleshoot), the microusb power port of the zero will need to be upgraded to a data port. That way, each pi zero gets power and Ethernet over 1 port, while getting a mouse/keyboard input (via a switcher box) on the second port. That would require a major re...

Hi - sorry to resurrect an old thread but is this image compatible with a pi Zero? Thx

Why not try it...

DirkS

Try

Code: Select all

sudo apt update
sudo apt full-upgrade

See e.g. https://www.raspberrypi.org/forums/view ... p?t=258038

How do I know which system I am using?

What did you install?

DirkS

Try disabling the overscan first by uncommenting the relevant line in /boot/config,txt

DirkS

What widget?
If you want to add an image to your post you have to upload it to a sharing site (e.g. imgur) and then add a link to the image to your post.

DirkS

You could use a shim like this one
