No signal (new install) Generic / 10.0

I've just installed 10.0 on a Gigabyte Brix 8250u connected to a Samsung AU8000 TV but I get no signal upon booting.

Brix is connected via a high speed HDMI cable (tried 3x different cables), all I see is the machine's POST screen, I don't even see the Libreelec logo.

The machine is up and I can SSH.

I've tried disabloing CEC on the TV.

Can anyone help?

Edit: even the installer wouldn't run, I had to install Libreelec whilst connected to another screen and then plug this in afterwards. The installer gets to the choice of installer/live etc and then the signal drops once you make your choice.

LibreELEC:~ # tail /sys/class/drm/*/status

==> /sys/class/drm/card0-DP-1/status <==

disconnected

==> /sys/class/drm/card0-DP-2/status <==

connected

==> /sys/class/drm/card0-HDMI-A-1/status <==

disconnected

Try to disable "Input Signal Plus" in General -> External Device Manager on your Samsung TV.

Thanks for the quick response, this was off by default and I tried it enabled/disabled with no luck.

With pastekodi you can upload the whole log situation, so if you can paste its URL here, we can see some action going on under the bonnet.

Thanks for this, log below:

You're still at log level 0. You can activate log level 2 by creating an advancedsettings.xml. Then reboot, and run pastekodi again.

Apologies, updated log below:

Thanks again.

Dec 09 23:23:10.200081 LibreELEC kernel: [drm] Got external EDID base block and 1 extension from "edid/edid.bin" for connector "DP-2"

Create a custom EDID.

PS: The specs say, you have a "Mini DisplayPort" (DP) and an "HDMI 2.0" port. The log says, DP is in use, so the connected HDMI cable makes no sense without a DP adapter. Can you switch to "HDMI 2.0" port in the EFI / BIOS settings?

This confuses me too, I have a few Gigabyte Brix machines in other rooms and they're the same. They report that they're using DP despite being connected via HDMI.

• The Intel i915 kernel driver is crashing/complaining early.
• Don't use getedid until something is visible. Remove the configuration it with getedid delete.
• Not all log messages are stored. To see the early ones add log_buf_len=4M to the APPEND line of /flash/syslinux.cfg. Use dmesg|paste after reboot.
• Try to boot LE 10.0.0 and a LE nighty from USB stick to test different kernel versions

The TV loses signal before you even see the Libreelec boot logo but with the stable release I at least see the installer/live options but as soon as you choose to either install or run "live", the display drops.

I've just tried the latest nightly and I don't even see the (installer/live) options. It boots, loads for a couple of seconds and then nothing.

Scratch that, I thought it was booting from the USB stick but it was booting from the HDD. I get the exact same thing with the nightly, boots, choose installer/live and then instantly lose video.

OK, then I think DP-1 is the "Mini DiplayPort", and DP-2 is the "HDMI 2.0" port. Can you check EFI / BIOS settings anyway? Maybe you can switch among HDMI and DVI mode for DP-2.

Annoyingly there's very few configurable options in the BIOS, nothing for HDMI/Displayport etc.

attached is a photo from my NUC (hoping GigaByte hasn't changed your bios much)

cause the digi cam doesn't get it, the grey fields are:

- 64 MB

- 256 MB

- HDMI

- NONE

Thanks for all of the help, really appreciated.

Gigabyte have done a great job at neutering the available options, there's nothing that allows you to configure the HDMI/DP ports.

I'll take some pics first thing tomorrow.

Thanks again.
