Hi Sly, Your evdi kernel module for DisplayLink docks failed to compile. It likely couldn't generate your initramfs, leaving your 6.5.0-21-generic not able to boot.
Your logs say its trying to build version 1.11.0: ERROR (dkms apport): binary package for evdi: 1.11.0 not found Error! Bad return status for module build on kernel: 6.5.0-21-generic (x86_64) Consult /var/lib/dkms/evdi/1.11.0/build/make.log for more information. This is a bit old and outdated. You can re-install the DisplayLink drivers from the upstream source, that has a newer version of evdi: https://www.synaptics.com/products/displaylink-graphics/downloads/ubuntu That will probably remove the old evdi and install a newer one. Alternatively, you can remove the old evdi dkms entry and install evdi- dkms from the Ubuntu repositories which has a evdi compatible with 6.5.0-21-generic. DisplayLink support is kinda bad on Ubuntu, but its what we must do to have working displays with our docks.
