No, the name doesn't matter. I would be surprised it it would )

I have the same issue here. LG detects Pi as PC and disables all the picture enhancements. I think using enhancements is a matter of preference, but the issue is clearly about connection. I used to have Pi3 and there was exctly same problem, but in the end I somehow (!) managed to get it detected as a media player. There was no clear way - only switching HDMI ports back and forth, changing resolutions, clearing "smart" remote settings, even TV factory resets - all that kind of a hassle. But now I switched to Pi4 and the issue is back and nothing works.

I have contacted LG technical support and that was completely useless. Their answer was "you're using non-standard HW + SW - so look from that side"

On some screenshots from the Internet I can see WebOS did have "Auto detect" feature on HDMI ports, where one could just switch it off and set everything up manually, but my set doesn't have this option. (Nor it should be there according to LG support)

So my the question is - is there anything I can adjust in HDMI settings on Pi side (config.txt for example) that could affect the Pi to TV HDMI handshake?

Wise people have pointed out that there is ntpdate utility that does NTP date sync. Can be installed on raspbian and taken to LibreELEC to be used instead of the monstrous cmd I posted earlier

Attached ntpdate that I've got on raspbian just in case

Seems like no suggestions?

Well, I haven't got to the bottom of this. Tried every possible log/option/idea that I could think of.

I believe the reason is somewhere inside systemd, when it decides that no time sync is needed:

systemd[1]: Condition check resulted in Network Time Synchronization being skipped

Puzzled, I started writing simple NTP client myself, but then found a very nice way to query NTP servers right from the shell.

So I worked around the problem by adding this to .config/autorun.sh:

sh -c 'while true; do date +%s -s@$((0x$(printf c%47s | nc -uw1 europe.pool.ntp.org 123 | /storage/xxd -s40 -l4 -p) - 2208988800)); sleep 3h; done' &

This starts sh in background that loops every 3h. It makes single UDP packet, sends it to europe.pool.ntp.org, parses the reply and sets system time from it. Funny, but this single line works _in place_ of all the systemd+ntpd+settings+headaches+whatever!

So far so good.

HTH

Oh, and this requires having xxd at hand, which LibreELEC doesn't have by default. So I've compiled it myself.

Unzip (forum doesn't allow tgz extensions) then copy to RPI and extract: tar -xvf xxd.tgz

xxd.tar.zip

It turned out that there were not any ntp addresses in the correct gui location.

Thanks for the suggestion.

Yes, I've tried adding custom NTP servers to that list, but that didn't make the trick. BTW, I've read somewhere on the Internet, libreELEC has its own set of default NTP servers, so setting these in the GUI is optional.

What's interesting though is that I don't see it trying any of the custom servers at all. It just ignores this setting!

If that makes additional sense - the issue depends on the networks RPI is connected to. I've tried to use my cellphone Wifi tethering - and it worked normally. Unfortunately, not with my home connection. I've checked every possible setting on the router, but didn't see anything related or somehow linked to NTP. System time on the router is correct - so the NTP is accessible in provider network.

Any chance you have forgotten to enable the "Wait for network" option in the LibreELEC Settings Add-on? A 20 seconds timeout usually does it for Wifi.

Yes, I tried that option (up to 30 sec), but no success

Hi all,

I've been struggling with date problem. It starts, connects to LAN/Wifi but nothing works. Date is wrong and displayed as Apr 2019.

Changing date from cmdline fixes the problem but obviously doesnt survive the reboot.

Checked ntp availability/firewall - everything works as expected. IPv6 doesn't seem to be configured on router.

I can see this in systemd log:

Apr 11 19:28:37 kodi1 systemd[1]: Condition check resulted in Network Time Synchronization being skipped.

but I can't think of anything that I could do to it.

connmand doesn't try to sync the time according to the logs.

No manually configured ntp servers are set in the GUI.

Read tons of time-related posts/solutions but nothing seems to be helpful.

Any suggestions are much appreciated.

LibreELEC 9.2.1 (i've tried latest 9.2.3 but that made no difference)
