Weird display (framebuffer?) issue.
I've got a 480x800 display in HDMI-1, and a 1920x1080 in HDMI-2. I normally keep HDMI-1 in an orientation where I have to set its rotation to "left" and it then becomes 800x480. But whether or not I rotate it, HDMI-2 shows the contents of HDMI-1 on the right side of the screen, but with the top line of pixels missing. I've tried numerous adjustments in arandr and in /boot/config.txt to no avail. Also of note is that anything I click on on the right screen, the actual click happens about 2 inches to the left of wherever the arrow is. If I move the arrow onto HDMI-1, it doesn't show up in the area of HDMI-2 where HDMI-1's screen is showing, but the effects of me clicking do.
But where it gets really weird is that if I set the rotation of HDMI-2 to inverted, it works perfectly fine, other than it's annoying having my monitor upside down.

SERVO2040 (New User)
Hello,
I’ve never used a raspberry pi before and I have a SERVO2040 and I’m not sure if it’s working right. What happens is the onboard leds are rgb but only flash red. Also I’m using Mu Editor and circuit python. I have no idea what I’m doing but I’m just following the circuit python welcome guide. Also the leds turn like whitish when I press serial and any key in Mu Editor.

Help with Electronic Ink Screen
Hello
I need help setting up my e-ink raspberry pi screen.
I recently bought a Raspberry Pi 4 model b and a programmable e-ink screen.
I've been searching on the internet for tutorials on my topic, but all i can find are animation demos for the screen. I am wondering if it would be possible to use it as the main display, just like using a monitor with the micro-HDMI. My monitor is the Waveshare 4.2 inch e-paper module. Thanks

Problems when running python code on raspberry pi 4b
I've been trying to connect a raspberry pi 4b to ads1115 for a few days now. I've never worked with this board before and I'm totally new to this. The wiring is correct from what I have seen on the internet, but when I download the library from the Adafruit ADS1X15 I get an error when running the code. I work with Python and operating system is Raspberry OS Lite. I have tested the board with Arduino and C++, it works without any problems. This is part of my thesis project and I would appreciate your help.

Hey! I have being at this for a while, I am trying to stream the video captured on my pi camera on my raspberry pi to my PC live via the network. Although I have done so successful the latency has been high, the lowest I have gotten is 5 seconds which is way to much for my project.

Sixfab 4G/LTE Cellular Modem Kit or USB Cell in / USB wifi out RPI5
Hello, and if you are reading this thanks for taking the time to help. I was curious, before I buy a Sixfab 4G/LTE Cellular Modem Kit (Telit LE910C4-NF) for my kit I was wondering if a 3G/4G LTE USB antenna modem with sim or 4G/5G Dual Band USB antenna modem with sim would work just fine across country as my data input source, while also on the same Pi 5 8gb board using a USB Dongle of some type to output Wifi 5 (and 6/6e if possible) to output the mentioned wifi? Also, when I program the Pi to function in this manner, could I also program (or would I even need to program?) the Pi 5 to also allow output via the ethernet port, or would I need a micro usb to Ethernet Port device? Thanks in advice for any help. This is my first project with the Pi and I want to have the right hardware before messing around with trying to program this, as well as using OpenWRT as I think i must. If the dongles will provide a similar result as the Sixfab option it is much cheaper. Any suggestions on the model of each usb device you would use? Thank you again in advance!

Raspberry 4 retropie after shutdown I have to reflash
So basically I got this raspberry 4 for 25 dollars, I've never owned a raspberry before nor have I operated Linux. I got an SD card and a usb flash and got it to work. I choose a game, my start button to go back to emulation station doesn't work so I shut it down. When I power it back on it gets me to a screen like cmd on windows with the name "busy box" nowhere on the internet have I found a similiar problem. Every time I shut down I have to reflash because I can't get to emulation station a second time without doing so

Serial UART not working with non-booting Fedora39
# About my pi
- OS: Fedora Server 39
- Model: 4B
## The Problem
Fedora Server goes through U-Boot, then starting services and then the screen is black (No Signal). My Serial UART also refuses to connect after this time.
## What I've tried
- Re-formatting the SD Card using a variety of tools (arm-image-installer, RPI imager, dd, Rufus, balenaEtcher)
- Setting the "nomodeset" parameter
- Connecting the Serial UART, with and without the 3v3 and 5v connections.
### How I've tried to connect
- Screen and minicom on Arch Linux
- Putty on Windows
Please ping me in any response!

no green light on pi 4
Hi there. I was running mainsail on my pi and until recently it was working fine. Now only the red light comes on and it doesn’t seem to boot. I confirmed my power source is 5.3v . I tried plugging it into an external monitor to see what it is doing and it said no signal. I checked the sad card. It seems fine, but I tried a second one just in case. I can’t see any physical damage to the card, and no reason why it would have suffered any. But I’m at a loss.
