I wanted to give OSMC a try on my RPI 4 (4GB) again and did a fresh install with the latest image. Downloaded today, so it’s the one that should officially support RPI 4.
Unfortunately, after the (obviously) installation and the reboot, right after the splash screen, my screen is blank.
I tried two different TVs and a Dell monitor.
I tried two different power supplies (both original from RPI 4).
I tried two different SD cards, one of them is completely new.
I tried some settings in the config.txt but all without success. (like hdmi_mode=2, gpu_mem_… and so on).
I use an official RPI HDMI-cable. Tried it also with both HDMI ports.
Raspbian works with the same PI, so it shouldn’t be a hardware issue.
Now I don’t know what to do…
Any ideas? How can I get logs to investigate further? Can I create an ssh file after the setup to activate it?
If, what is happening, is the same that’s happening to me on my Pi3, ssh is not reachable, it just stalls after trying to log in and then timeouts.
This is just after a brand new installation with osmc-installer.

After a few minutes the ssh session just dies without getting a shell.
@sam_nazarko I’m seeing something very similar on a Pi3 that’s I’m running headless.
After the upgrade to the new kernel, I was unable to SSH to the box. Even with -v I could see that ssh was going through the usual handshake motions and would then freeze, so the OS was working, at least partly.
So I assumed a broken installation and reinstalled from a fresh image. Same problem.
I connected it to a TV and keyboard and all worked just fine. Enabled wifi, so I could try that if ethernet wasn’t working.
Rebooted without either TV or ethernet connected and WiFi no longer even pingable.
Reconnect ethernet and WiFi becomes pingable, (as well as ethernet). SSH logon still hangs:

(There’s quite a delay after the “pledge network” line.)
So, in my case, it seems to be something to do with the lack of TV or HDMI connection. It’s also a bit difficult to debug.
Update: A few more data points:
Disconnecting ethernet causes wireless to become unpingable.
Disabling/stopping mediacenter (via TV/keyboard/command line) also stops the logon screen appearing on the TV at reboot.
I can only SSH when connected to the TV, even when mediacenter isn’t running.
If I pull the HDMI cable and reboot, SSH gives a “connection refused” error. Reconnect HDMI, power-pull and SSH again works.
I have a USB-TTL cable I could use to try to debug the problem. Can you advise what needs to be enabled on OSMC to get it to work? (Of course, lots of instructions for RaspiOS available.)
I’m having the same problem, get a black screen, just after the splash screen on reboot.
Log shows that mine is a problem with Mesa. I get lines and lines of “mesa warning: failed to remap” then it hangs at loading the mediacenter.
Tried reinstalling, downloading the img multiple times. I’ve used 5 different SD cards and two Rpi4 units. Get the same errors every time.
I’m not sure this applies to you, since “the same problem” could cover several possible cases, but there was a partial workaround provided a few days ago for devices that aren’t connected to HDMI: Headless Pi boot failure - #3 by fzinken
It’s partial in the sense that it only works for (no-HDMI) headless devices where the Kodi GUI isn’t required.
Not sure if this reply was intended for me, but my pi4 is connected by HDMI to a monitor and is intended to be used always connected to a screen/TV. I can ssh to it, so would be happy to access it and paste any logs that are necessary to identify the problem.
The generated log was about 37Mb because of a lot of repeated lines in the Kodi Old Log section. So I deleted about 30k repeating lines and uploaded it manually : https://paste.osmc.tv/asoviwazux
[ the following section was repeated and I deleted the lines between Aug 25 and Aug 26:

TBH, the log shows no EDID information, so it’s probably the same issue as others have been seeing, though the use of a monitor has confused the issue a bit.
Sam has produced a kernel fix that you might wish to try out.
I’d suggest you wait a bit until the gateway 502 problem has been fixed.
Still no hdmi output (I get a blue screen with the OSMC logo at boot and then everything goes blank. The monitor then complains of no signal on HDMI input).
