Just remembered.
that vc4-kms-v3d-pi4 has a problem and the devs disabled V3D until they fix it.
My /boot/config.txt
dtoverlay=vc4-fkms-v3d
dtparam=i2c_arm=on
dtparam=spi=on
dtparam=audio=on
dtoverlay=w1-gpio
camera_auto_detect=1
display_auto_detect=1
initramfs initramfs-linux.img followkernel
#hdmi_group:0=1
#hdmi_mode:0=4
#hdmi_drive:0=2
disable_overscan=1
gpu_mem=512
max_framebuffers=2
[pi4]
# Run as fast as firmware / board allows
# arm_boost=1
This dtoverlay=vc4-fkms-v3d has fkms instead of just kms, notice the f
The entire section of
dtoverlay=vc4-fkms-v3d
dtparam=i2c_arm=on
dtparam=spi=on
dtparam=audio=on
dtoverlay=w1-gpio
display_auto_detect=1
is required to get the work around configured for video.
This might be all you need to make the 5.16.11-1-aarch kernel to work with V3d?
If you used the step 3 script to install your DE or WM, it should have modified the config.txt like above.
The script copies this file to /boot/config.txt
