Is your screen connected to HDMI-0 or HDMI-1? The default for single screen is HDMI-0 (the one closest to the USB-C power jack). It was this. I changed from HDMI-1 to HDMI-0 and it worked. thanks guys, sorry this was such a simple error! Thanks for the update and it's good you've solved the problem...

Hi, I have a Raspbian on Raspberry pi 3. My crontab execute an script to shoot a picture every 2 minuts. I also have apache2 to show these pictures on a php page. My /dew/root becomes 100% usage. I connect (via ssh) and delete some Gb, reducing at 54% the used ( /dev/root). The problem is when I re...

My available settings differ from yours. I only see composite selection, nothing else. Do you still have "enable_tvout=1" set? That's probably why. Instead of trying to create a framebuffer for a non-existent HDMI monitor that vnc will share, you can start vnc in virtual mode so that it creates it'...

I'm using the vilros package. so its 32GB uSDHC card.

I'm guessing that's a "kit" - P4B, PSU, keyboard ... etc. More details please eg. a supplier/description link.

I get a rainbow screen every time I try to boot. I have tried: - reformatting using disk utility to FAT32 - reformatting using SD Card Formatter to FAT32 - reloading the NOOBs files onto the SD card - starting the RPI4 without an SD card (it gets the expected 4 short green flashes) Any help or idea...

* bump * Nobody got an idea what could be wrong? Please don't "bump" - the majority of contributors to this forum are volunteers and some problems may be rare and thus it may be some time before someone can comment. I suspect your WiFi issue may be a "result" of possible "file corruption" because o...

... On Linux shrinking is possible but on MacOS i dont know. The best is to use exact the same SD Card Model. Raspbian expand the Partition size without asking on first boot... Some older SD Card reader dont support writing on >32GB cards. Using the "exact" same SD Card Model is unlikely to make an...

Sorry for my English. I have a Samsung SDXC 128GB card on it, I want to install Rasbian, but the manual writes about formatting to FAT32, but this format does not support files larger than 4 GB, what should I do? (and Win7 doesn't want to format to FAT32). Can it split the card into Fat32 and NTFS ...

Have you considered using gnuplot ? It's great for viewing data from files. PeterO Perhaps also try "QtiPlot" - I use it for, amongst other things, generating my PSU loading curve graphs eg: https://www.cpmspectrepi.uk/raspberry_pi/MoinMoinExport/USBPowerSupplies.html#The_.22Official_Raspberry_Pi_P...

Something's not quite right - I'm using fairly basic 32Gb uSDHC cards** in my P4B's and the Shutdown Options pop up does so in < 1sec. It's a genuine Sandisk, I ordered it directly from their website. My Shutdown Options takes approximately as long to load as Chromium. Chromium takes 6-10 seconds. ...

Hmm, spoke a little too soon. With HDMI connected to either port I get the 4 raspberries, a very brief flash of a white panel with a raspberry on it, then the display dies. The disk light continues to flash away for a couple of seconds, so I'm pretty sure it's booting, but the monitor output is get...

Hi,

same problem here, I tried everything,
none of the solutions are working.
How can I ssh if it never connected to a monitor or something?

I have the model 4GB

Have you read through this (esp. para. 3)? https://www.raspberrypi.org/documentati ... /README.md

Latest Raspbian Buster. When running from a HDD, it takes nearly a minute for the shutdown dialog to load after clicking the button in the menu. When running on a Sandisk Extreme Pro, it takes nearly 10 seconds. Chromium opens faster than the shutdown dialog in both cases. Why? I would think the sh...

Should a pi4, with the same power provided to the header block, boot from a pi3 maintained (fully up to date) Raspbian install, or should I start with a fresh flash? I take "power provided to the header block" to mean they are powering their current Pi directly to the 5v GPIO pin. ... That's what I...

Should a pi4, with the same power provided to the header block, boot from a pi3 maintained (fully up to date) Raspbian install, or should I start with a fresh flash? Many thanks. Not quite sure what you mean by "with the same power provided to the header block,"** - that aside, so long as it's Rasp...

Hello everyone, new member here so please bear with me! Although I’m new to the forums I have had some experience with Raspberry pi but now I have a handheld Raspberry pi 3b and I’m having issues because the screen position is too far to the right and cut off. I have read the info and seen the vide...

Is there any way that I can run 'startx' and start the desktop remotely so I can then connect to my pi with VNC? I'm running my RPi 4 headless but I'd like to be able to access the desktop whenever I need it without having it always on taking up system resources. Running 'startx' from an SSH client...

Does a RPi 4 run (headless) with a SD card (latest Buster OS) that was created on a RPi3? I just expect the RPi 4 to arrive before the HDMI adapter... Assuming no "strange"/unusual entries in cmdline.txt or config.txt I would expect it to be O.K. Possibly worth updating/upgrading before trying. Trev.

I got a new pi 4 and don't have a SD card. I am trying install OS but it's saying that it can boot only from SD Card. Is there anyway I can install OS onto Pi 4 without SD Card and HDMI cable using only Mac/Windows? I have a Pendriv. And in a discussion I saw someone saying "First boot MUST be from...

That makes sense. I don't have a circuit at the pi, just the wires to the pins. I can move the pi closer to the button inside the case (to shorten the wire) and try better wire. Would a ferrite core bead on the wires help? Thank you for your help! I did something like this except i changed the scri...

Did you set the WiFi country code?

What happens if you try:

Code: Select all

sudo apt update
sudo apt install php-curl

? (AIUI, apt is now preferred over apt-get)

I soldered two jumper wires to this button: https://smile.amazon.com/gp/product/B0094GP7SQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 and attached them to GPIO 3 and ground (5 & 6). The pi is inside an arcade cabinet and the button comes out the back so I can turn the pi on and off (off using ...

I still prefer to use "dd" on any nearby Linux pc with plenty of hdd space. You take out the micro-sd from your raspberry pi, move it to a card reader on a Linux PC, do some stuff from a terminal (see "man dd") and wait for a long time without indication while it laboriously replicates an 'image' f...

My Pi 3B occasionally powers on by itself. I am running retropie 4.4 and I have a button connected to pins 5 & 6. If I power down (with the button or menu) and don't unplug it the pi will power itself up once every day or two. Any idea why? I was thinking maybe a power surge or power loss but none ...
