Do you use the right config.txt option?

"Switchable Graphics" doesn't enforces iGPU usage, so it doesn't help.

Maybe chewitt can explain whether the "nouveau" driver has to be blacklisted, or if there is no need to do that, because the driver doesn't exist on LE. I'm asking because setting the eGPU driver on the blacklist usually enforces iGPU usage.

Yes, disable the eGPU in BIOS. You have a good chance to run LE with the iGPU.

That's the relevant driver modules on Ubuntu:

Try to load the "nouveau" driver on LE. My research says the driver has issues with Kodi, so it's probably not available on LE for good reasons.

PS: If "nouveau" isn't on LE, it could be a good idea to stay with Ubuntu. When you autostart Kodi on it, you maybe have all you need.

He came from this thread where he said it's OK on Raspbian Buster. I think it's about internal WiFi, because he didn't mentioned an adapter.

Manufacturers often change hardware revisions of some electronic parts. So the explanation you're asking for could be a different hardware revision of your display, compared to the one of add-on developer. Maybe you're lucky, and the necessary changes of the source code are pretty small.

It's very unlikely to find someone with the same hardware here, who solved your issue. The driver of your case display works for most of the output, so I bet it's a driver problem (not fully compatible to your display).

If you have programming skills, you could try to find the source code of the LCDproc add-on, and adapt it for your needs. Because your hardware is quite exotic, I think that's your only option.

OK, then I'm running out of ideas, too. Maybe you still have guarantee, and get a replacement. Try it on a friends TV before you replace it.

Download a full Linux, like Ubuntu, and run it in "live" mode. If everything works, look for the loaded driver modules, and try to load them on LE.

I think that's a good way to figure out the usability of an "old laptop".

Thanks for the tests. I compared your guisettings.xml to mine. I found a difference, which could be the cause:

<setting id="audiooutput.dtspassthrough">true</setting>

Set this setting to false.

LE creates symlinks for all mounts. Some services can't go beyond such a symlink.

Does it work if you define two separate buttons instead of one switch button?

Activate "HDMI and Analogue" sound, and test analogue output on RPi's headphone jack.

Disable I2C and UART for testing.

Make sure your HDMI cable is HDMI 2.0 or 2.1 standard (ready for 4K).

<setting id="audiooutput.channels">8</setting>

Set it to 2.

chapas :

It's a usual error that the RC generates multiple events, but you only need one event when you press "g".

You can fix it by changing some timings at the CEC adapter settings.

Go to Settings -> System -> Input -> Peripherals -> CEC Adapter.

Then edit the timings like this (example from my settings, last three entries):

• Remote button press delay before repeating (ms): 800
• Remote button press repeat rate (ms): 100
• Remote button press release time (ms): 400
  

PS: Sorry, I've just recognized you are using a keyboard, which makes double triggers unlikely. The error log says that a JSON call can't be executed. The call wants to change this line at /storage/.kodi/userdata/guisettings.xml:

<setting id="lookandfeel.soundskin" default="true">resource.uisounds.kodi</setting>

Make sure you are using the default skin.

You can't pass-through A/V signals on RPi, but you could trigger an HDMI relay when the RPi turns on.

If your RPi is always on, you could write a script to trigger the relay by RC.

PS: I know that so called "sharing switches" exist for USB. They automatically switch to the active source. Maybe switches like this exist for HDMI, too.

Router - ZyXEL Keenetic Ultra II, no 2.4, only 5GHz...

I remember that other RPi 4B users have the same problem with 5GHz WiFi. Because it works with the same Hardware (same RPi, same PSU) on Raspbian Buster, I assume it's a bug on LE. My guess about the bug is that LE uses a different energy management. 5GHz needs more energy than 2.4GHz. Maybe write a bug report to give the bug more attention. I think that's all you can do.

Just a little explanation: On a Linux OS like LE, the OS selects the the eGPU (your Nvidia) as default. It seems like the driver for your eGPU is not available, so the OS switches to the iGPU (your Intel). If you really think it's worth to go into depth, provide a log file.
