OK,

I finally managed to see the low resolution screen with the logs enabled.

The log is https://paste.libreelec.tv/rational-crane.log

This is the xrandr output:

The problem happens randomly, when I start Kodi with AV Receiver and TV off,

After a week I can say the problem of the black screen at boot is gone.
Thanks again for the support.

But now I have another problem...
Sometimes I get a readable screen but at a wrong resolution (see attachment).

It's not a big problem, can be fixed with a reboot.
I think is not related to EDID; can be fixed with an additional grub parameter?

tode

I think is correct now

grub:

menuentry "LibreELEC edid" {
   search --no-floppy --set=root --fs-uuid e2a66b6d-8b16-44a0-b051-2396c0db69b3

   initrd /edid.cpio 
}

dmesg:

Thank you mglae ,
I'm going to test it in few days and i'll give feedback,
tode

Hi,
thanks for help.

mglae : I rebuilt the "edit.cpio" archive (in attach) but the problem persists (see dmesg in attach)

Da Flex : the debug file is https://paste.libreelec.tv/mint-foal.log (with the new generated edid.cpio)

tode

Thanks mglae ,

in attach my complete dmesg and the edid.cpio I put in "/flash/" dir.

I also have the "edid.bin" file in "/storage/.config/firmware/edid/edid.bin": I think this is the one found at time 14.104286 in dmesg.

# find / | grep edid.bin
/run/kernel-overlays/firmware/edid/edid.bin
/storage/cpio/lib/firmware/edid/edid.bin
/storage/.config/firmware/edid/edid.bin

The problem I have is occurring randomly: this boot I didn't have the black screen.

Thanks for help,

Hi,

I have a dual-boot (Ubuntu + LibreElec 11.0.4) NUC8i5BEK system with Yamaha AV Receiver and Sony Full-HD TV.
When I boot I have all devices turned off: the NUC turn all on via USB-CEC adapter.
But i get (randomly) a blank screen; to see LE screen I need to reboot (via Kore).

So I think I need a custom EDID file to load on boot. I followed the official instructions at https://wiki.libreelec.tv/configuration/edid :

• find connected device (card0-DP-1)
• create edid.cpio file
• save edid.cpio in /flash/

but then I need to load it via grub, configured in ubuntu partition.

This is my grub setup:

menuentry "LibreELEC edid" {
   search --no-floppy --set=root --fs-uuid e2a66b6d-xxxx-2396c0db69b3
   linux /KERNEL boot=UUID=e2a66b6d-xxxx-2396c0db69b3 disk=UUID=3310112e-xxxx-571af07148af quiet initrd=/edid.cpio drm_kms_helper.edid_firmware=DP-1:edid/edid.bin video=DP-1:D
}

but the edid file is not loaded.
This is the dmesg log:

# dmesg | grep edid
[    0.000000] Command line: BOOT_IMAGE=/KERNEL boot=UUID=e2a66b6d-8b16-44a0-b051-2396c0db69b3 disk=UUID=3310112e-be99-4319-81ac-571af07148af quiet initrd=/edid.cpio drm_kms_helper.edid_firmware=DP-1:edid/edid.bin video=DP-1:D

Any help?

Thanks a lot,

After enabling mouse support in Kodi, my K400 touchpad works just fine with my 3rd gen Intel NUC

Thank you, it worked,

tode

Just connected a Logitech K400 Plus keyboard with touchpad: the touchpad/mouse doesn't work.

It works with other PC Linux or Windows.

In attach my dmesg.

The device is recognized with no problem:

Could it be a conflict with libcec, recognized as mouse?
