2 years ago It's not a function that the kernel driver should undertake (it was the firmware under legacy and vc4-fkms-v3d). libcec should be able to do that for you though - IIRC Kodi makes use of it in that way. I can't recall if you need to setup udev rules or not.

2 years ago Where in the userspace should this be implemented then? Should this be done by the graphical environment, or perhaps by a script run as a service by systemd at boot?

2 years ago I'd recommend cec-ctl rather than libcec (which is largely unmaintained).

2 years ago Odd thing about cec-ctl there are times if does not seem to work. For example, I have a Vizio TV that just seems to refuse to work with cec-ctl but works fine with libcec, i.e. cec-client. Makes no sense but true.

10 months ago I'd recommend cec-ctl rather than libcec (which is largely unmaintained).
Thank you for that tip. I tried, but unfortunately I didn't get cec-ctl working either. It seems to have similar types of problems that I have in cec-client now.
I'm new here, and it's possible that I just haven't realized some basic things that I should know. Also I may have posted this to a wrong place - please notice me if so. Anyway I have searched the forums a lot and tested everything quite patiently.
I have been reading these discussions here and in Raspberry Pi forum to get a solution to a problem with libcec with Full KMS. It really seems to me like that, when I switch from kms to fake kms (fkms) in /boot/config.txt, cec-client works with absolutely no errors, just like it's supposed according to the manual. I have understood that probably libcec isn't just working well with Full KMS, but what about cec-ctl?
When Full kms is enabled, cec-client first seems to communicate with the TV: It wakes up with 'on 0' and switches the active source from the TV cable broadcast to the Raspberry Pi with 'as'. But when I switch the TV with its own remote control to another HDMI or to any other source, CEC seems mess up. After that the communication with the TV fails, and will not recover to the original.
My LG television uses CEC version 1.3a, so it might be also a compatibility problem with the versions. But it still works with the Fake KMS, so there's still something different in CEC functionality between the Fake and the Full KMS. And 1.3a isn't really so old, is it? :) I'd like to test this with a TV that supports CEC 2.0 later. My goal is to get this working with new and old televisions, so trying TV with the CEC 2.0 support wouldn't be the solution, but just a part of the troubleshooting.
Cec-client with Full KMS:
When switching the TV to another HDMI from the TV itself, cec-client immediately prints out this: 'DEBUG: [ 48301] changing physical address to FFFF DEBUG: [ 48301] SetDevicePhysicalAddress - not setting invalid physical address ffff'
'scan' command shows that the TV's power status has changed from 'on' to 'unknown', and it also shows up in the cec output: TV (0): power status changed from 'on' to 'unknown'
After that I try to switch the Raspberry Pi to the active source with 'as', cec-client starts flooding these messages eternally: DEBUG: [ 340915] TransmitImageViewOn - 'image view on' already sent NOTICE: [ 340915] << Recorder 1 (1) -> broadcast (F): active source (1000) TRAFFIC: [ 340915] << 1f:82:10:00 ERROR: [ 340915] CLinuxCECAdapterCommunication::Write - ioctl CEC_TRANSMIT failed - tx_status=00 errno=64 TRAFFIC: [ 340915] << 1f:82:10:00 ERROR: [ 340915] CLinuxCECAdapterCommunication::Write - ioctl CEC_TRANSMIT failed - tx_status=00 errno=64 DEBUG: [ 340915] failed to make 'Recorder 1' the active source. will retry later DEBUG: [ 341915] TransmitImageViewOn - 'image view on' already sent
After that has happened, the game is over: I can switch the TV manually to the Raspberry Pi's HDMI input, so that cec-client calms down. I can also still switch the tv on with 'on 0'. But the problem is that, 'as' command is not working anymore.
Cec-ctl with Full KMS
I found your reply that cec-ctl is not using libcec, which is probably in the center of this problem, so of course I gave it an opportunity: sudo cec-ctl -d/dev/cec0 --playback -S --cec-version-1.4 Shows the topology 'almost' correctly, and shows that the TV is on. I have also tested the same with cec 2.0, but there was no change. This is the only point in the outcome that shows something incorrect: CEC Version : Tx, OK, Rx, Timeout Physical Address : Tx, OK, Rx, Timeout
sudo cec-ctl -d/dev/cec0 --to 0 --image-view-on --cec-version-1.4 This wakes the TV up, at least on the second try.
sudo cec-ctl -d/dev/cec0 --to 0 --active-source phys-addr=1.0.0.0 --cec-version-1.4 This doesn't do anything. Also there's two things wrong in the outprint: 1) Physical Address : f.f.f.f 2) Logical Address : Not Allocated
Here's some information on my Raspberry Pi 3 Model B:

I'd be grateful for any help.

10 months ago I might be tempted to add:
vc4.force_hotplug=1
(assuming you are using first hdmi port - HDMI_A_0) to cmdline.txt (on same line).
Reboot and see if anything is different.
But this is just a guess.

Thank you so much! That was the solution.
Cec-client is now working properly and switches the source rapidly by the command to the Raspberry Pi from any other source.
For some reason, cec-ctl is not working, but that's not a problem anymore. I'll go with cec-client or libcec-python.
