VNC display problem on remotely managed PiHello,To help with digital things around my moms house,
VNC display problem on remotely managed Pi. When i remote connect to a Pi, the chromium tab shows an alternating black screen and a normal but massively distorted/compressed 'normal' screen that is un-usable. The pi is updated, on a stable network connection, adequately powered.

I got a RPi5 but..... (undervoltage detected)
If I connect the power supply with a random USB-C -> USB cable to my PS4, it says undervoltage detected, can I ignore it? Like will it damage my RPi5 in any way?
Or is there any official USB-C -> USB cable for RPi5 which I can use to connect with my PS4?

ERROR: [main] failed to start the concentrator modify start.sh script
Hi
I am getting "ERROR: [main] failed to start the concentrator" when testing out packet forwarder. I think I found the solution here
https://forum.rakwireless.com/t/rak2247-spi-pi-supply-failed-to-start-concentrator-follow-up/4679
I need to modify "start.sh" script, but I have no idea what commands to type in so I get to it and do modifications.
here is the script that I need to get to:

Xwrapper not always working on PI3
I have a minimal raspberry os install with xfce on, using xorg-xserver-legacy, I have set anybody as Xwrapper configuration and I can run startx from systemd and ssh fine on raspberry 4; I am using the exact same install (same sd) for raspberry 3 too and all startx sometimes (decided at boot) doesnt work complaining about permissioms etc... (Like legacy was not installed or not configured) Putting need_root in the wrapper seems to solve the issue, I'd like to avoid that tho; I'd like to understand what makes it work all the time under pi4 and not pi3

Make Install Error 255 Permission Denied
Hi all,
I am following miner installation guide here:
https://github.com/maco2035/DiyHeliumHotspots/blob/master/RAK2287/Raspberry%20Pi%204B/Guide.md
I messed up something on a line where it says:
If you do not want to have to put in your password a million times in the next step, you can create a ssh key in the sub steps below otherwise skip to the next step.
Create the ssh key pair.
ssh-keygen -t rsa
Press enter three times to accept the defaults.
Set up your user to use the key pair.
ssh-copy-id -i ~/.ssh/id_rsa.pub pi@localhost
so I followed steps and came to the point:
Make the executables:
make install
when making install it asks for password and then gives all errors below as I messed up something in previous steps so cant make an install
I think I made a mistake where it says pi@localhost where I had to input my username???
please help sorting this outĀ š
myusername@raspberrypi:~/sx1302_hal $ make install
make install -e -C libloragw
make[1]: Entering directory '/home/myusername/sx1302_hal/libloragw'

removed lists
I was running sudo apt-get update on my raspberry pi, however, due to some network issues, I got some errors. I did not know it was due to network issues, but thought that it was due to some damaged list, so I ran the following command:
sudo rm /var/lib/apt/lists/ -vf
After that, I ran sudo apt-get update again, but the issue persisted, after which I concluded that it must be a network problem. I moved to a place with a better network, and ran sudo apt-update again. The previous error didn't show up, so I knew that it was a network error all along, and that the issue was gone. However, another error showed up:
pi@retropie: Ģ $ sudo apt-get update
apt-get: /lib/arm-linux-gnueabihf/libgcc_s.so.1: version GCC_3.5' not found (required by apt-get)
apt-get: /lib/arm-linux-gnueabihf/libgcc_s.so.1: version GCC_3.5' not found (required by /lib/arm-linux-gnueabihf/libapt-private.so.0.0)
apt-get: /lib/arm-linux-gnueabihf/libgcc_s.so.1: version GCC_3.5' not found (required by /lib/arm-linux-gnueabihf/libapt-pkg.so.5.0)
apt-get: /lib/arm-linux-gnueabihf/libgcc_s.so.1: version GCC_3.3' not found (required by /lib/arm-linux-gnueabihf/libstdc++.so.6)
apt-get: /lib/arm-linux-gnueabihf/libgcc_s.so.1: version GCC_3.5' not found (required by /lib/arm-linux-gnueabihf/libstdc++.so.6)
apt-get: /lib/arm-linux-gnueabihf/libgcc_s.so.1: version GCC_3.0' not found (required by /lib/arm-linux-gnueabihf/libstdc++.so.6)
I'm assuming the libraries I removed earlier using sudo rm /var/lib/apt/lists/ -vf caused this? How do I fix this?
I already tried sudo apt-get install --reinstall gcc and sudo apt-get install --reinstall libstdc++6. They both just got the same results as above.
I got the idea to run sudo rm /var/lib/apt/lists/* -vf from this thread over here: https://askubuntu.com/questions/454895/update-manager-bug-encountered-a-section-with-no-package-header/454899#454899

[Video] Raspberry Pi 5 not booting or going to diagnostic screen? Led Lights are Red, Green, Solid R
How can I reflash the firmware/bootloader to see if that's the issue? My other 5's work fine with same power supplies (tried multiple supplies). I removed all connections including the SD card to see if it entered diagnostic mode; it didn't. Here's a video of the status LEDs. Led Status Lights do not match anything on the stickied thread in the Pi troubleshoot forums.

RPI pico code breaks when I delete a comment
I have written code for my pico that allows a multiplexing 4x7 segment display i made to run on its own thread. Initially the code was not working so i wrote some test code which i then commented out.
I got the main program to work but when I delete the comment the code stops working. After some troubleshooting ive determined thread is likely dying from some sort of memory issue and running collect() in the loop fixes this. Here is the code in its current state. I would love some help with why this happens and ideally a good method of managing memory
import machine, utime, _thread
from gc import collect, mem_free
class Display:
def __init__(self, seg_pins, cathode_pins):
self.leds = [machine.Pin(pin, machine.Pin.OUT) for pin in seg_pins]
self.cathodes = [machine.Pin(pin, machine.Pin.OUT) for pin in cathode_pins]
def display_digit(self, digit):
self.outputs = {
'0' : [1,1,1,1,1,1,0],
'1' : [0,1,1,0,0,0,0],
'2' : [1,1,0,1,1,0,1],
'3' : [1,1,1,1,0,0,1],
'4' : [0,1,1,0,0,1,1],
'5' : [1,0,1,1,0,1,1],
'6' : [1,0,1,1,1,1,1],
'7' : [1,1,1,0,0,0,0],
'8' : [1,1,1,1,1,1,1],
'9' : [1,1,1,1,0,1,1],
'none': [0,0,0,0,0,0,0]
}
for i in range(len(self.leds)):
self.leds[i].value(self.outputs[digit][i])
def display_number(self, number):
digits = list(str(number))
utime.sleep(0.00)
for i in range(len(digits)):
self.display_digit(digits[i])
self.cathodes[i].value(1)
utime.sleep(0.002)
self.cathodes[i].value(0)
self.display_digit("none")
display_output = 1234
seg_pins = [20, 19, 26, 27, 28, 22, 21]
cathode_pins = [15, 14, 12, 13]
display1 = Display(seg_pins, cathode_pins)
def persistant_display():
utime.sleep(0.2)
global display_output
while True:
display1.display_number(display_output)

Raspberry Pi 4 Model B (I2C Range)
I'm trying to connect 125 units of ATTiny85 and I am not sure if it works within the available I2C address.
Where can I check the starting address and the end address?
I wanted to know if it will fit all of it.
If it doesnt start at address 0 or 1, what address that it starts?
Or is there anyway I can change the pre-reserved starting address? maybe change some config?

GPIO BUSY on Raspberry pi 3b+
I have written a code that moves a robot car with arrow keys and takes a picture on every key press. For controlling the robot car motors, I have a seperate file where I use the Motor function from gpio zero and assign the pins and define the directions (left, right, forward, backward). However, when I run my code for controlling the car and taking pictures I immediately get the error stated in the title. I have searched online a bit but found nothing useful.
I'm suspecting its because I have the motor function defined on a seperate file which is then called to my main file.
I'm running 64 bit bookworm os.

Urgent - Canāt get raspberry pi 4 to run a simple script on startup
Iāve tried every single tutorial and forum post I could find to get it to just run a small script that Iāve written that launches a Processing sketch file.
- The script is set to be executable
- The path is /home/notions/startup.sh
What Iāve tried already
- Editing rc.local
- Editing .bashrc (this works but I have to manual open the terminal first
- Iāve tried autostarting the terminal with @lxterminal in the autostart file
- Tried editing crontab -e
- Tried systemd
No matter what I try, whenever I reboot the Pi it just wonāt autostart anything.
Any advice or help would be hugely appreciated.
Iām under time pressure for a project
