piCore 9.0.3 boot to python script with GUI

[Juanito]

I don't have the means to (easily) test, but on an x86/x86_64 machine you would need the graphics-KERNEL extension, which I see is not present in the piCore-9.x armv6 repo...

graphics-4.9.22-piCore added to the repo

Hi Juanito,
thank you, I will try to add this extension. Out of curiosity, why do I need it? Only to handle the HDMI connection? I read the comment in the .info file. Just to be sure, do I have to add the line

Code: [Select]

dtoverlay=vc4-fkms-v3d to config.txt?

[Juanito]

I suppose the audio is output via a graphics (hdmi) connector, hence the need for graphics-KERNEL.

I don't know if you need "dtoverlay=vc4-fkms-v3d" or not - hdmi graphics works in 2d mode without it, but I don't know if hdmi audio is enabled.

I can't get the audio working. If I use the overlay for 3d graphics, I don't even get video output. I tried forcing HDMI setting "hdmi_drive=2" in config.txt but nothing changes. Even using the command "amixer cset numid=3 2" does nothing.

I am sorry Juanito, I made a silly mistake. Now everything is working, thank you so much!

EDIT: alsa-modules-KERNEL.tcz and alsa.tcz are the only extensions needed.

I saw that before loading the GUI of my python script, the piCore wallpaper is shown very briefly. Is there any way to remove it completely?

Hi Pacca
It's probably caused by  ~/.xsession  calling  ~/.setbackground.  So you can remove that line from  ~/.xsession.

Hi Rich,
it was exactly that, thanks!
