SRU Request:

[Test Case]
1) Enable the -proposed repository, and install the new ubuntu-drivers-common (1:0.8.1.1).

2) Check that the dpkg-dev package is also installed.

3) Restart your computer, and see if everything works correctly when
accessing the desktop.

[Regression Potential]
Low. No code was changed, only a missing dependency was added to solve the problem.


__________
On a machine with I+N, I install with focal 20.04 image. I didn't turn on auto-login. I checked "install 3rd party driver" during installation. It does install Nvidia driver (440.82+really.440.64-0ubuntu6).

On first boot, I double check by run 'prime-select query'. It return
nvidia.

run nvidia-smi, no program is using NV GPU.

Run lsmod | grep nvidia, I got:

I run

$ sudo prime-select intel
$ sudo prime-select nvidia
$ sudo reboot

After reboot, nothing changed.

However, previously, on the same machine, I once get it works. (nvidia-smi show some X related process use GPU, glxinfo -B show Nvidia). I remembered I create another admin account, and later on, I found it's fixed. I didn't remember what else exactly make it happened.
I re-installed again, and try to do more tests, can't fix it so far.

LP: #1875315 have all the log that it first fixed.
