Broken usb-c to hdmi with kernel 5.18+

Files in EMMC /boot were named *linux515* renamed to *linux* and copied vmlinuz-linux to Image (as I could not create a symbolic link). Then saw dtbs/rockchip/rk3399-pinebook-pro.dtb was missing so copied it from the Armbian /boot/dtb/rockchip folder (after creating the folder).

-rw-r--r--  1 root root  30M Oct  1 16:08 vmlinuz-linux

All these details I found in the EMMC "/boot/extlinux/extlinux.conf" file:

LABEL Manjaro ARM
KERNEL /Image
FDT /dtbs/rockchip/rk3399-pinebook-pro.dtb
APPEND initrd=/initramfs-linux.img console=ttyS2,1500000 root=PARTUUID=1eeb7b54-686c-447f-80a7-b57c8d7b3345 rw rootwait audit=0 splash plymouth.ignore-serial-consoles


@mjrr15 

Kernel 5.15 from Armbian has the same issue. Eventually I ended up installing TwisterOS and the image comes with kernel 5.10 so there is no HDMI issue there. Give it a try.

Now, it would be nice to find a Manjaro or Arch image that has these older kernel versions available.
Ideally this should be fixed though as it's such basic functionality and it has been broken for a long time.
