How to consistently connect my RPI 5 to may laptop?
I own a RPI 5 and I just started using it. I used the RPI Imager to install the RPI5 software and had it connected to my home WIFI. I initially used an ethernet cable to connect it via SSH with PuTTY and allowed the use of VNC. I used VNC and all that and connected to the Pi via WIFI. I got to control it and do everything with it. But after not using it for a while, whenever I open my Pi, it doesn't seem to connect to the internet automatically. I do not own a separate monitor to see what's happening within the Pi. I also am not able to connect to the Pi again via ethernet. I try using PuTTY again but it just says that the network is unavailable. The only way I get to connect to the Pi again is if I do the whole process again of installing the RPI5 software with the Imager program. If anyone can help me with this please it would be greatly appreciated. Thank you!

Script to reboot program on pi os if it failed to launch
Hello everyone im making myself a personal signage display that uses chromium that sometimes throws up this error. I have everything automated using .bashrc (pi boots up, unclutter loads to hide the mouse) then the command chromium-browser āwebsite.comā -kiosk -incognito. It works 7 out of 10 times. The other 3 times I get thrown the error pictured below.
I was wondering if it was possible for me to make a fail safe that will detect that chrome didnāt successfully launch and commit a safe reboot to make a new attemptā¦ thanks!

Does the 7ā touchscreen draw significant resources?
I'm trying to use a seven inch touchscreen monitor with my pi4, but the program I'm running is lagging. I was wondering if it draws enough resources to make the pi slower or have slight delay, could anyone help me?

SSH into Pi 3A+
How can I ssh into my Pi 3A+ via USB? I have been following this video:
https://youtu.be/7nDJPidKSPA?si=PZm3fRWedA0UtWqu
Iāve tried both putty and Debian on WSL, but when I try to ssh, it cannot resolve the hostname. I tried to ssh into 127.0.0.1 and the same thing happened. When I try to view my network connections in Control Panel or usb devices in Device Manager, the PI does not appear as an RNDIS gadget. I can SSH through wifi, but I want to avoid that because when I move back into my dorm, it will be difficult to get my device added to the internet whitelist. What can I do now?

Won't boot from NVME
I used Raspberry Pi Imager from a Raspberry Pi OS running on an installed SD card to image a fresh Raspberry Pi OS image onto a connected NVME SSD drive. It completed and said it was successful after verifying the image that was installed.
I removed the SD card with intention to boot from the NVME.
It won't boot, though I changed the boot order to begin with NVME.
I plugged in another Raspberry Pi instance that is on a USB drive and it will successfully boot from USB after failing to boot from the NVME.
The NVME is seen by the Raspberry Pi, but as seen in GParted, the two partitions created on the NVME are "unknown" and either damaged, unformatted, or a device entry is missing, or something.
1. Can RPi Imager not install Raspberry Pi OS on an NVME drive?
2. If so, how should it be done, and how should the drive be prepared first (partition table, unformatted or with a filesystem)?
3. If not, what would be the best way to install Raspberry Pi OS onto this NVME drive so that it will boot from it?
4. Image shows Gparted reproting the NVME drive partitions
5. Can Raspberry Pi OS handle being installed on a drive that is ~ 500 GB, or does it have to be smaller instead?
6. I don't want to "copy" an install from an SD card, rather install "fresh" on the NVME
7. Oops, need to mention this is a Raspberry Pi 5
8. It appears the filesystem setup on the nvme drive is corrupted or otherwise wrong.

SSH Pi Connection
I am currently working with a raspberry pi 4 and a load cell sensor.
The sensor is hooked up to the correct GPIO pins on the pi, but I need to install the correct packages to access them through python.
I am currently accessing the pi through an SSH connection, but when I try to install a necessary package "pip3 install HX711", i get an error that "this environment is externally managed."
I've tried running this connection through a VM and the install worked, so why am I getting this error for just this package? Other packages installed just fine. Nothing on the internet has worked/ been useful. Thanks!

How can I fix this? OS: Raspberry Pi OS

Open CV on Rpi 5 very sluggish
Im trying to hookup 1, if possible 2 logitech usb webcam (1920x1080). The camera works fine in vlc and processing for pi but I want to use python and the openCV library. This however does not work that smoothly, the video is lagged and also seems choppy. Anyone know any particular settings I should investigate ? (there seem to be a lot and i'm not that familiar with this) or any other tips to get it working smoothly with python ?

Raspberry Pi 4 Push Button to run program
Hello, i want to use a push button to run a program on the Raspberry Pi 4.
For example, when I just click the button I want the program to run, I don't want the user to keep holding the button, I just need them to press it once and then my Python program will run.
What button should I order (if anyone has any experience) and if anyone has some good circuit configuration to connect the button to the GPIO pins, i'm not that experienced in the electrical side of things.
Thank you!

Using a 4TB Drive on Pi
I have a 4tb HDD hooked up to my Pi via a USB container
https://forums.raspberrypi.com/viewtopic.php?t=345542
Seems like I am formatted to MBR (Idk what this means I know sysadmin but not storage management) and limited to 2tb, how can I "change to MBR" (without formatting hopefully but doable) or otherweise make all 4tb available?
Trying to use this as a seedbox, plex, and backup NAS

Pi 5: How to add "lcd_rotate=1" to startup
I have a raspberry Pi 5 with Ubuntu server 23.10 installed with raspberry pi imager. My display is setup vertical so I need to manually do "echo 1 | sudo tee /sys/class/graphics/fbcon/rotate_all". A guide said this:
If you want this to happen automatically when you start your system, you need to modify your boot loader configuration to give it the correct options. In /etc/default/grub add fbcon=rotate:1 to the GRUB_CMDLINE_LINUX line:
GRUB_CMDLINE_LINUX="fbcon=rotate:1"
(Don't forget to run sudo update-grub after changing this file.)".
But I don't think my setup uses grub right? I've also tried setting it inside "/boot/config.txt" but that doesn't work either.

Powering Pi 5 via USB-C in Gadget Mode and Additional Peripherals
I'm planning to use my Raspberry Pi 5 in device/gadget mode via its USB-C port connected to my computer. At the same time, I want to connect a mouse to one of its USB 3.0 ports.
Given that I won't be using the official Pi 5 charger because the USB-C port will be occupied for gadget mode, can the Pi 5 still draw enough power from the computer's USB-C connection to both run efficiently and power the connected mouse through its USB 3.0 port?
_(Assume my Computer has a USB-C Port that can provide 100W, I am mostly asking if this is within the Pi's capabilities)_
Thanks in advance for any insights or advice!

- Running sudo apt update && sudo apt full-upgrade -y.
