dkms not auto-installing nvidia driver to all kernels?

[oshunluvr]

I upgraded to the 4.8 kernel line awhile back but kept the last 4.4 kernel just in case, so I have 3 kernel installed - 4.4.0-66, 4.8.0-32, and 4.8.0-39 - booting to 4.8.0-39.

I noticed this morning that dkms had not installed the nvidia-driver to all my kernels, although virtual-box was.

virtualbox, 5.0.32, 4.8.0-39-generic, x86_64: installed[/FONT]

I thought this odd and problematic because if I needed to boot to a backup kernel, I wouldn't have any GUI. Also, since I had booted to these kernels in the past, they obviously had nvidia in them at one point. My suspicion is that an upgrade to the linux driver removed all the old dkms installed nvidia drivers but did not install itself to the older kernels.

I tried sudo dkms autoinstall both without specifying a kernel version, but it did nothing and returned no output. I ended up manually installing the driver to the two other kernels.

I was wondering if anyone else had noticed this. I'll be curious to see what happens with the next upgrade.

@hear it seams ...no I do not see this .

It is here:

$ sudo dkms status

bbswitch, 0.8, 4.4.0-66-generic, x86_64: installed
bbswitch, 0.8, 4.4.0-67-generic, x86_64: installed
nvidia-370, 370.28, 4.4.0-66-generic, x86_64: installed
nvidia-370, 370.28, 4.4.0-67-generic, x86_64: installed

$ ls /boot | grep vm
vmlinuz-4.4.0-66-generic
vmlinuz-4.4.0-67-generic

And, just for grins I added the 4.8 kernel:

$ sudo dkms status
bbswitch, 0.8, 4.4.0-66-generic, x86_64: installed
bbswitch, 0.8, 4.4.0-67-generic, x86_64: installed
bbswitch, 0.8, 4.8.0-42-generic, x86_64: installed
nvidia-370, 370.28, 4.4.0-66-generic, x86_64: installed
nvidia-370, 370.28, 4.4.0-67-generic, x86_64: installed
nvidia-370, 370.28, 4.8.0-42-generic, x86_64: installed

PS - Also, for grins and giggles, I decided this morning to boot using the 4.8 kernel. It failed to properly load and run nvidia and I got a black screen.
So, I removed it.

I did a system-wide purge and now it's working again. I don't know why and likely never will. At least it's fixed...
