KMS goes to black screen with recent kernel
-
@blerkotron Yes, I confirm that, ES is working fine for me because I have switched off navigation sounds. It is a combination of new kernel, KMS and audio.
I wonder if it is a RetroPie problem or a kernel problem. -
@saccublenda Yes, I've seen this. I asked about it on the Raspberry Pi forum: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=316721
A few utilities to collect debug information were suggested, but they need building from source, I don't know how to use them, and I'm busy, so [shrug]
I assume that the Raspberry Pi OS team will be debugging this over the next few months as they move towards a Bullseye based release, so I'm just waiting.

An almost related comment from a Raspberry Pi engineer over on the RPi forums:
If [screen tearing] bothers you, it may be worth waiting for the bullseye image which will kms by default, which is the real solution for tearing
\o/
-
@busywait Yeah, I guess that a RetroPie image based on bullseye will fix it.
-
I tried the unofficial manual upgrade to bullseye but the problem didn't go away. I'm sure there's much more to it, but I wanted to try.

@darksavior I ran that script on a clean 64-bit install too. It was a smooth process but still some problems
- I was warned on the forum that there are still missing packages in the raspberry pi maintained bullseye repos (that's independent of the debian Bullseye release and repos)
- Raspberry Pi haven't previously supported upgrades to new OS versions
- The package python3-sdl2 that is needed by the RetroPi installer doesn't install because of unmet dependencies (at least last week when I tried)
- No, the blank screen issue is not fixed (yet?)
However, it will be good that kms becomes the default. I wonder how long until the RetroPie install script will support it [the bullseye distro]? 🤔

I think we have to wait for an official bullseye Raspberry Pi OS image (2-4 months from now), and then for a RetroPie image based on the former.
-
@busywait I only tried 32 bit and retroarch wouldn't compile due to missing sdl2 dependancies until I used this repo https://github.com/joolswills/RetroPie-Setup/tree/sdl_2.0.16

Just as an update, the official bullseye Raspberry Pi OS image was just released.
-
@devs: just to get an idea: as soon as bullseye will be the base of retropie: will we have to build a new image, or will buster be upgradable to bullseye?

New image, as always.
-
@mitu thanks for info, i will start the backup :D
-
@sirhenrythe5th I wouldn't be in such a hurry.
