Package: linux-image-6.1.0-9-amd64 Version: 6.1.27-1 Hello, I think kernel module hyperv_fb.ko is missing in the package. It was present in version 5.10.0-22 before upgrading to debian 12.
$ find /lib/modules/5.10.0-23-amd64 -name hyperv_fb.ko /lib/modules/5.10.0-23-amd64/kernel/drivers/video/fbdev/hyperv_fb.ko $ find /lib/modules/6.1.0-9-amd64 -name hyperv_fb.ko The impact is a regression when using debian as an Hyper-V vm. Screen resolution can not be changed anymore when editing GRUB_CMDLINE_LINUX_DEFAULT.
