Installed LibreELEC-Generic.x86_64-12.0-nightly-20230605 build that comes with Kodi build 21.0-ALPHA1 (20.90.101) on an old Gigabyte G3 laptop having 2 GPUs Intel and amd
The laptop is connected to a SONY TV using its HDMI port.
Startup is fine and LibreELEC splash is displayed on the TV, but goes blank when the Kodi screen appears on the laptop. How do I get this to display on TV? No success so far. Any areas I can investigate.

1. Tried switching off/on TV, disconnecting/reconnecting HDMI cable
2. sshed from another desktop to this laptop and killed the kodi process, The TV shows the LibreELEC screen momentarily again and goes blank as Kodi restarts.
3. LibreELEC:~ # find /sys -name "edid"
/sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-HDMI-A-1/edid

@ozyaus

Good to hear that the problem is solved. Just a few tips:

- Please be cautious with pasting longer texts into the forum. We prefer to use pastebin websites as mentioned below in bold red letters, just to keep our forum server clean.
- There is a LibreELEC forum where you can get more direct help from its developers, especially on nightly builds. We typically address the more generic problems regarding Kodi.

Thread marked solved.

You now basically workaround that GBM does not have proper multi-monitor support.
What you could do to make it work: Disable the laptop screen when booting via the kernel command line.

That way GBM and the kernel should use the HDMI out only.
