Hey folks, OK, here was the procedure (as a reminder, I’m on stretch, testing):
— boot into 4.6, verify everything works, purge both 4.7 kernel and 4.7 headers, purge all nvidia-* (and nvidia-dkms was indeed installed) — purge xserver-xorg-video-nvidia — install xserver-xorg-xideo-nvidia and nvidia-driver (which pulls in nvidia-dmks as a dependency, among others) — I’m still booted into 4.6, so watch the install script build nvidia-dmks package for 4.6 only. — reboot (into the only kernel I have: 4.6), verify all is ok — install 4.7 and 4.7 headers. I observed that the install script and post-install hook did not rebuild nvidia-dkms for 4.7 — reboot into 4.7 and everything works. So, to wrap up: I’m happy for now, but I clearly don’t understand something about how nvidia-dmks built for 4.6 also functions on 4.7 Did we get lucky here, or do we need a bug filed to get the post-install script to check what kernels are there and build the kms accordingly? Thanks for your individual help off-list as well.
