I just got my first Pi4B, it is up and running Buster ofc. I have no idea how to benefit from two HDMI displays and which one is active. Is there a good tutorial how to use dual displays ? How do I install "screen for Buster" ? Just outof curiosity Carl / Helsinki This might help, it should work ou...

Maybe you need to enable passthrough? https://kodi.wiki/view/Raspberry_Pi_FAQ ... support.3F

I assume you can connect to your receiver with HDMI.

Btw, where did you see the Pi4 advertised as mediacenter? Surely not by the Foundation?

There's a FAQ on the Flirc RPi 4 case page where question 9 specifically adresses the gpio ribbon cable issue: I haven't tried it myself, if you do please let us know if it fits. I now see the FAQ entry, but the link points to a page with a table with multiple cables listed. The connectors on all t...

Or run the script as a systemd service at startup.

You could also optionally make a systemd timer and unit to run your script to avoid pulling down more dependencies (cron).
There's an echo in here

Great minds...

It would be helpful if you use the 'Code' tags when posting command-line output, like this: pi@raspberrypi:/ $ ls bin boot.bak dev home lost+found mnt proc run srv tmp var boot CreateDirsCopy etc lib media opt root sbin sys usr pi@raspberrypi:/ $ ls -lr total 79 drwxr-xr-x 12 root root 4096 Jan 20 2...

Interesting results. Do you have a different keyboard you could try?

jj_0

Also, you coul look into lightweight container systemd-nspawn if you don't need full virtualisation

This thread might be helpful.
It's probably related to startup power draw,
using a powered USB hub might help.

A general script, which takes input from fdisk of the source disk will be a good addition to the Pi tools.

There are some tools like that, see https://robotzero.one/headless-pi-zero-backup-clone/

I'll try to ask there, although I don't think it's distribution related. So have you confirmed this by replicating the issue while running the Raspberry Pi supported Raspbian Operating System? No, but it seems to be a problem with qt since wireshark has GUI It might be an issue with the capabilitie...

Hi jj_O again, Thank you for the tips. I had tried disabling systemd-timecyncd before, I had found that blog when searching. It didn't work before but it appears to have worked this time. This setup does not have access to the internet - just a LAN cable between the server and the Pi. I did edit th...

The mount command you have used doesn't return an error message, but its usage information. This usually means the command line you have used is missing something. In the mount command you use I see the <remotetarget> but not the <dir> local directory where you want to mount it specified. I would e...

Apparently (I've only found out now, sorry) there is a different standard timeserver running on Raspbian these days, called systemd-timesyncd. This interferes with ntpd. So you could try to use that by de-installing ntpd again. Or disable it and use ntp . But it is probably best to stick to the stan...

the values inside the parenthesis are the ones to use for metric, the ones outside are for imperial/inch.

Thanks! I get it now.

did the math on the linked "slim connector", it turned out as 52.3mm it will probably be a tight fit on the narrow end of the pillars.... I tried the math ( No. Positions/row x (2.54) .100 + (1.50) .059 ) as well even though I don't quite understand the (2.54).100 nor (1.50).059 in the formula, I g...

All the above from hortimech might apply, but also: pi@raspberrypi:~ $ sudo mount.cifs //PC-PRO/share/b] - My Code Here is what returned: I don't think anything actually happened here. Usage: mount.cifs <remotetarget> <dir> -o <options> Mount the remote target, specified as a UNC name, to a local di...

You might have to enable the NTP service so it starts every boot:

Code: Select all

systemctl enable ntpd.service

Apparently you can also check if it's enabled, by using:

Code: Select all

systemctl is-enabled ntpd.service; echo $?

If this returns 0 it's disabled, if it returns 1 it's enabled.

Put the uSD-card in a different Linux-running computer, mount the rootfs that's on the uSD card somewhere, e.g. at /mnt and then edit /mnt/etc/shadow. Look for the row with the username whose password you want to reset and remove the long garbled string between two colons following the username . Af...

Well... Or the files were on your uSD card of course.

The case you linked to is a Rpi 3B+ case and not for the 4. So it likely won't fit.

Oops. I guess I was suffering from the heat as well when I ordered it. My Pi 3B+ will be very happy with its new case I hope.

So I finally got my Flirc Kodi Edition case to test against my Wicked Aluminum/Pi Holder case from Barch Designs. Room temp is about 80F or 26.6C. Tests were taken consecutively on two separate Pi4s in the same exact location. The tests were started at about the same time after booting up. The Flir...

I'm not sure if you are aware of it, but Systemd has a special facility for creating files and/or directories at boot: systemd-tmpfiles. This can be configured by placing a .conf file in the /etc/tmpfiles.d directory.
If you use that instead of your own unit it might work OK.

Just got my Barch Designs Pi Holder machined aluminum case for my 4GB Pi 4. It's very pricey at $70 USD, but I figure well worth it for piece of mind on a machine running 24/7 and avoiding fan noise and dust. Ran a sysbench stress test on it for 10 minutes and it did not go over 58C. https://i.imgu...
