Black screen over HDMI

Please the output of

cat /var/log/Xorg.0.log

Hi all,

Yesterday after struggling with the volumio os to make the screen work, I decided to try raspbian to see if the screen would work correctly. And it did, right out of the box, plug and play without any extra lines on /boot/config.txt. So basically what I did was to merge my volumio config.txt with the raspbian config.txt. Here is the resulting file for those that might run on the same issue as I did:

volumio@marxamp:~$ cat /boot/config.txt
initramfs volumio.initrd
[cm4]
dtoverlay=dwc2,dr_mode=host
[all]
arm_64bit=0
gpu_mem=32
max_usb_current=1
dtparam=audio=on
audio_pwm_mode=2
dtparam=i2c_arm=on
disable_splash=1
hdmi_force_hotplug=1
force_eeprom_read=0
include userconfig.txt
dtparam=audio=on
camera_auto_detect=1
display_auto_detect=1
auto_initramfs=1
dtoverlay=vc4-kms-v3d
max_framebuffers=2
disable_fw_kms_setup=1
arm_64bit=1
disable_overscan=1
arm_boost=1

I would like to thank @dvo and @gvolt for helping me out with this issue.

you should add your additional settings on userconfig.txt, not on confix.txt.

the end result will be the same, but you will keep your changes after a system update, because config.txt is overwritten, userconfig.txt is not
