[SOLVED] 9.01 does not start

[Venerdi]

@Venerdi you can read the official config.txt documentation here: https://www.raspberrypi.com/documentatio...g_txt.html

That's not to say I fully understand what all those options do, but it's a start.

Thanks, interesting.
I don't really understand the issue either, but I have confirmation that my problem was due to the vc4-kms-v3d driver.
If I understand correctly, it's not a moOde problem, but a kernel problem. Maybe because version 9 uses a new kernel...
And finally, maybe I can enable the command again
max_framebuffers=2
which concerns the number of monitors used, and I don't think it created any problems.
...you always learn something new...
