** Description changed:
ubiquity calls
```
ubuntu-drivers install $FREEONLY $NOOEM --package-list
/run/ubuntu-drivers.autoinstall
```
to generate package list during live system but "ubuntu-drivers install" not
only install packages but also create some config files for switching nvidia
mode (e.g. on-demand) and change the runtime config as well (e.g. modify the
iniramfs).
Thus, not only package list needs to be referred but also the
configuration.
---
In ubuntu-drivers-common, which read the "/run/ubuntu-drivers.autoinstall" to
install package. It also skipping the nvidia-mode changing (made by
ubuntu-drivers install).
```
$ cat ubiquity/target-config/31ubuntu_driver_packages
#!/bin/sh
set -e
# install all packages that "ubuntu-drivers autoinstall" installed into the
# live system. Ubiquity calls this with --package-list
/run/ubuntu-drivers.autoinstall
PKGLIST=/run/ubuntu-drivers.autoinstall
[ -e $PKGLIST ] || exit 0
for p in `cat $PKGLIST`; do
apt-install $p
done
```

We need to use a same approach to make sure the nvidia mode is same on a
same system (either all handing by ubuntu-drivers install or change the
logic to maintainer script in each package).
+
+ ---
+
+ [Impact]
+
+ * According to Nvidia README, the RTD3 (Runtime D3) doesn't support on
non-laptop machine
+ * Patch make system not enable RTD3 unless it's a laptop
+ * Install Ubuntu with "third-party packages" enabled, will not get same
+ GPU configuration by running "ubuntu-drivers install"
+
+ [Test Plan]
+
+ * Install Ubuntu on machine with "third-party packages" enabled
+ * On laptop with Nvidia RTD3 supported GPU. The configuration file
'/run/nvidia_runtimepm_supported' will be created.
+ * Execute "prime-select query" should get "on-demand"
+
+ [Where problems could occur]
+
+ * With non-laptop machine use RTD3 supported GPU may use more power
+
+ [Other Info]
