Hi,
I am currently investigating myself why during a travel session at the beginning of February I suddently could not drive an external monitor anymore.
I now reinstalled the OS based on danielt's scripts with crypted Debian Buster - the dptx.bin file is present in initramfs and loads.
The errors I see are the exact same as in zackw's last post.
I got three different adapters - 2x DP Alternative Mode to HDMI and 1x a pure DP one.
I don't remember which adapter worked before, but one most definitively did. Now all three only result in "Enable dp failed -19".
It makes no difference if i use the 5.4 or the 5.5 kernel - so far I did not install the stock OS again.
Any other part of the adapters(Network, USB-A, microSD Readers) work.
Its all a bit strange.
