Re: Pi 3B - no HDMI output after latest apt-get kernel upgrade

Getting back to the topic at hand (no HDMI output after latest apt-get kernel upgrade), the following work-around got me going under the new kernel, *though it does not fix the root cause.* The issue seems to be in the HDMI subsystem failing to properly identify the connected display. Adding the fol...

Re: Pi 3B - no HDMI output after latest apt-get kernel upgrade

If your system is configured to use HDMI, kodi will go looking for the HDMI. Not finding the HDMI, kodi won't start. I didn't realize your Pi was configured to auto start kodi at boot. You don't say whether you see the rainbow screen, the raspberry logos, or any normal boot time service startup mess...

Re: Pi 3B - no HDMI output after latest apt-get kernel upgrade

My 3B+ boots the same kernel from USB with no problems (though that kernel was from a fresh Buster install, not an upgrade under Stretch, like on my 3B.)

That's interesting... and curious.

Re: Pi 3B - no HDMI output after latest apt-get kernel upgrade

I see that kernel 4.19.58 had just been made available via apt-get, so I've just tried that version. The problem persists with that kernel, as well. So again, I've reverted back to the older (working) kernel.

Re: Pi 3B - no HDMI output after latest apt-get kernel upgrade

If it helps anyone able to troubleshoot this, here's another little tidbit to add. Ordinarily, my VNC sessions have always followed the resolution of my HDMI display (1920x1080.) However, when booting under the new kernel (with the HDMI display dark), I found it necessary to add the following lines ...

Re: Pi 3B - no HDMI output after latest apt-get kernel upgrade

Rather than hijacking a thread about a kernel update on Stretch, wouldn't you be better served posting a "kodi on Buster" thread?

This thread is not about kodi. It's not even about Buster.

Just a thought.

Re: Pi 3B - no HDMI output after latest apt-get kernel upgrade

I just did a bare-metal Buster install on a Pi 3B+ that I had on hand, and it is now running the very same updated 4.18.57-v7+ kernel, and the exact same display parameters in /boot/config.txt, as I have on my problematic 3B. The HDMI is running fine on the 3B+ with Buster, in this configuration. So...

Pi 3B - no HDMI output after latest apt-get kernel upgrade

I have a Pi 3B running Stretch. This Pi is my Kodi system. It runs the legacy video drivers (not GL or "Fake GL"). This system has been running perfectly for a year, driving my 1080p HDMI flatscreen beautifully. Yesterday, I performed a "sudo apt-get update" and "sudo apt-get upgrade", and among the...
