Taking a look at the linked bug (I forgot to mention that plymouth failed to start as well):
I blacklisted hyperv_fb and explicitly load hyperv_drm in /etc/modules I also added hyperv_drm into /etc/initramfs-tools/modules. This fixed both plymouth and the login screen came back as well. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1989649 Title: [Hyper-V] Login screen does not appear Status in linux package in Ubuntu: Incomplete Bug description: Below are the packages were updated.
