Display port (over USB-C) stopped working on amd+nvidia laptop
Hi, I am having problem with detecting external display over USB-C which support DP after latest system update (including nvidia drivers update). I have reverted back to drivers 570.144 among other drivers but DP is not returning (with 580.95.05 even HDMI stopped working).
Command I used sudo downgrade nvidia-open-dkms nvidia-utils lib32-nvidia-utils nvidia-settings libxnvctrl.
TL; DR I called multiple commands and found out that the DP is connected to the AMD GPU, but I cannot seem to get it to work with different modprobe calls. I am running EOS on a Legion 5 15ARH7H with Wayland 6.4.5 and 6.12.53-1-lts kernel. This problem occurred once before (about half a year ago), and a reinstallation helped, but I would like to avoid that this time. Below is a sea of outputs. Any help is appreciated 
Command which help me point to DP + amd connection:
~❯ sudo mount -t debugfs none /sys/kernel/debug 2>/dev/null || true
~❯ sudo bash -c ’
for cdir in /sys/class/drm/card[0-9]; do
card=$(basename “$cdir”)
vend=$(cat “$cdir/device/vendor” 2>/dev/null)
dev=$(cat “$cdir/device/device” 2>/dev/null)
pci=$(basename “$(readlink -f “$cdir/device”)”)
name=$(cat “/sys/kernel/debug/dri/${card#card}/name” 2>/dev/null || echo “?”)
printf “%s pci=%s vendor=%s device=%s name=%s\n” “$card” “$pci” “$vend” “$dev” “$name”
for s in “$cdir”-/status; do
[ -f “$s” ] || continue
printf " %s: %s\n" “$(basename “${s%/status}”)” “$(cat “$s”)”
done
echo
done’
