As I needed edid overwriting myself today here is a short howto on how to boot completely without TV / AVR but having correct EDID information. This will work for intel and radeon:

# Find out the connected port

Code:

fritsch@bsw:~$ cat /sys/class/drm/card0-HDMI-A-1/status
connected

Could be HDMI-A-2 on your setup and so on. On my system it is HDMI-A-1 - you need to remove the card0- when working with this strange later on. If yours differs you need to alter all HDMI-A-1 in the following steps to your matching ones.

In my case it's HDMI-A-1 continue to change /etc/default/grub to look like:

Code:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=HDMI-A-1:1920x1080@50D drm_kms_helper.edid_firmware=HDMI-A-1:edid/edid.bin"

This will do two things a) it sets my default resolution to 1920x1080@50 and activate the digital output with D - which is not a typo, but written correctly directly behind the @50 which is my target refreshrate as I use LiveTV most of the time. Second is for loading a firmware to overwrite the edid that we will capture now

Before doing this make sure that you booted the whole system with AVR / TV on correctly and everything is working as you want it as we need to copy the edid in a working environment

Code:

sudo mkdir -p /lib/firmware/edid
sudo cp /sys/class/drm/card0-HDMI-A-1/edid /lib/firmware/edid/edid.bin

Now we need to make a little hack and also convince ubuntu to load this edid.bin in initramfs. Create /etc/initramfs-tools/hooks/include-edid-data file and write into it:

Code:

#!/bin/sh

PREREQ="udev"
prereqs()
{
   echo "$PREREQ"
}

case $1 in
prereqs)
   prereqs
   exit 0
   ;;
esac

. /usr/share/initramfs-tools/hook-functions
# Begin real processing below this line

if [ ! -e "${DESTDIR}/lib/firmware/edid" ]; then
    mkdir -p "${DESTDIR}/lib/firmware/edid"
fi

if [ -r "/lib/firmware/edid/edid.bin" ]; then
   cp "/lib/firmware/edid/edid.bin" "${DESTDIR}/lib/firmware/edid/"
fi

manual_add_modules i915 radeon
exit 0

Now make it executable:

Code:

sudo chmod +x /etc/initramfs-tools/hooks/include-edid-data

We are nearly done, finish with

Code:

sudo update-initramfs -u
sudo update-grub
sudo reboot

Now enjoy.

For OpenELEC you need to follow: http://wiki.openelec.tv/index.php/Configuring_a_Custom_xorg.conf#tab=Intel instead

See the Linux installation guide on the Download page. Scroll down to the instructions on downgrading. Remove Nightly PPA, add Unstable PPA.

Do I need to be concerned if I see

Code:

ERROR: failed to initialize egl

In my logs? I've set up a minimal ubuntu server install according to this tutorial with slight modifications because I use an nvidia ION GPU, installed nvidia-340 and left out the intel drivers, looks like those nvidia drivers ship with their own libegl files, which are also used by the system if I check with ldconfig.

Code:

ldconfig -p | grep libEGL
        libEGL.so.1 (libc6,x86-64) => /usr/lib/nvidia-340/libEGL.so.1
        libEGL.so.1 (libc6) => /usr/lib32/nvidia-340/libEGL.so.1
        libEGL.so (libc6,x86-64) => /usr/lib/nvidia-340/libEGL.so
        libEGL.so (libc6) => /usr/lib32/nvidia-340/libEGL.so

Would a Kodi debug log help? I guess this is more to do with the system side of things?

Specs:
Kodi (17.0-BETA7 Git:2016-12-27-1420882). Platform: Linux x86 64-bit

edit: I've noticed that the 64bit version of libEGL.so wasn't linked properly, updated the symlink (which was wrong for whatever reason, guess I broke something will testing things), but the error is still the same.
