Hey, I am buying a pi for the first time for a school project and after the project for personal use. I am buying the canakit Raspberry Pi 3 kit. I planned initially on getting the 3b+ however I realized it would not ship in time and I got the 3 kit without realizing it wasn't a 3b+. This isn't a b...

As the title says, just received my RPi4B/4GB from The PiHut, & the HDMI output is dead, not a hint of anything from either socket, trying with my 2 brand new microHDMI cables, the only thing that appears to work is the new PSU! This is a straight swap over of the mSDHC card from my RPi3B+ which I ...

Hi, I connected it to a TV; my initial problem was the HDMI not working probably. After that I recreated the SD-CARD through the adviced procedure, putting NOOBS (latest version, also tried Light version) on it, but that doesn't seem to work at all, because after putting it in the Rpi4, the FAT32 p...

how would one exit the noobs v.3.1 screen to safely shutdown? https://i.imgur.com/sNmsHbj.png It's quite some time since I last used NOOBS but, IIRC, something like de-select all ticked O.S.'s pending their installation then, hopefully, the Exit button (Esc) should be active. (From your screenshot ...

... Before doing anything else, assuming you can login directly with the Pi connected to a display + keyboard + mouse go back into raspi-config and change the password! Then retry enabling SSH and then try logging in directly and then via PuTTY using the new password after re-booting. NB: , and bei...

Are you able to enable / have you enabled SSH for Raspbian via the "dummy" ssh file method (option 3 here: https://www.raspberrypi.org/documentation/remote-access/ssh/README.md ) ? If so, can you remotely login via SSH (perhaps via your, hopefully still working, P2B) and post the output of these tv...

I simply use now headless buster, only access via ssh.

with X-forwarding enabled maybe? That's the "simplest" approach Pi (or other box with X-win support) to Pi.

Hello, sorry if this is in the wrong section but I'm new here and to using Raspberry Pis. I'm using a Pi as part of project and was trying to SSH into it from putty on windows 10. I've activated SSH on the Pi via rasp-config and have the IP address. When I connect via Putty I get to the login and e...

... Does your Pi4 or screen change resolution when booting noobs(as mine does)? eg 480p to 640 to 1024? And does it flick off and on when it changes? ... W.r.t. above question the answer is, regardless of whether the NOOBS installer has been used or whether Raspbian has been installed from an image...

... I also tested the latest Raspbian as you suggested, but the behaviour is the same: no output, with the red LED constantly on while the green LED blinked showing that the Rpi4 was apparently booting. Are you able to enable / have you enabled SSH for Raspbian via the "dummy" ssh file method (opti...

Works also with #hdmi_force_hotplug=1 Any line in /boot/config.txt that is prefixed with a # is ignored by the system as it's just a comment. Which is what I'd suggested @Pavel try to check whether hotplug forcing was necessary - it seems it wasn't, just a valid group and mode needed. Trev.

Hello I bought a Raspberry Zero W from a German dealer. But he has a different chip than usual. I bought a Raspberry Zero W from a German dealer. But he has a different chip than usual. An ELPIDA is normally installed. IMG_20200124_201140.jpg That's the PoP (Package-on-Package IIRC)** mounted memor...

Works ! I've specifying the following instructions in the config.txt : hdmi_force_hotplug=1 hdmi_group=2 hdmi_mode=82 ... and reboot system Glad you've got it working. Given that tvservice -m DMT did not report any preferred or native mode(s) I'm guessing that it passes EDID data that could not be ...

As I understood, the only place where one can configure HDMI is config.txt file and impossible with raspi-config . Correct ? Here I've found a link that suggests different modes for different types of monitors. http://www.cpmspectrepi.uk/raspberry_pi/MoinMoinExport/OptimisedDisplaySettings.html My ...

2.5A from the official power supply seems to be not enough anymore for the Pi 3 with buster? On different systems I get the lightning strike icon, my students get it too! Even the 3A adapter does not seem to be enough? I have not used my bench power supply yet but that might be a solution to check ...

I am quite a noob to raspberry pi and I am only just getting my head around it, until I accidentally short circuited the ground and 5v gpio pins with a piece of metal that I hadn't noticed was on my desk, as a result the usb port stopped working and I have since had no way of moving the mouse or ty...

It's a Raspberry Pi 4, 2GB. Here is the output of all four commands. pi@raspberrypi:~ $ tvservice -n [E] No device present pi@raspberrypi:~ $ tvservice -m CEA Group CEA has 4 modes: mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive mode 16: 1920x1080 @ 60Hz 16:9, clock:148MHz progressive mode 9...

For clarification - what model(s) of Raspberry Pi? It might also be informative if you can post the output of these tvservice commands (for both):

Code: Select all

tvservice -n
tvservice -m CEA
tvservice -m DMT
tvservice -s

Hi, Andy from RealVNC here. I'll try to clear up some of the confusion if I can: "vncserver" is an alias for "vncserver-virtual" (it's actually a symbolic link), so both should be equivalent (we changed it to vncserver-virtual a while back in an attempt to make it clearer that the command is creati...

I tried to connect from Windows computer via RealVNC viewer (standalone .exe VNC-Viewer-6.19.1115-Windows-64bit.exe ) and that worked. The reason why it doesn't work with UltraVNC is because starting the VNC server in virtual mode: vncserver-virtual -randr=1920x1080 does not take into an account th...

I'm running raspian on a Pi3B+. I have two printers installed under CUPS, a Brothers MFC-7860DW and aN Epson EcoTank ET-2760. I can open jpegs with both "ImageMagick" and "image Viewer", but "ImageMagick" has no print option and "Image Viewer" responds with "Unable to print file". Is there another ...

... What type of uSDHC card reader/writer are you using to write the card with? (Eg. built-in-card slot or USB-based device plugged in to a laptop maybe?) How old is the computer you are using? Since you refer to a "micro SD adapter" if it has a full-sized SD slot that may not be fully SDHC/SDXC co...

For any Pi, using Raspbian and RealVNC, and that may be required to run headless (ie. without a display temporarily or "permanently") I strongly suggest that use is made of the RealVNC server's virtual mode. FWIW, I have posted several examples here: https://www.cpmspectrepi.uk/raspberry_pi/MoinMoi...
