Re: kernel 4.7.0 and nvidia

Show all headers | View raw

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.

Cheers!
