Ubuntu Desktop 3.4: Proprietary GPU and Wi-Fi drivers

Finding out whether a machine needs a proprietary driver, where those drivers live in the archive, the Secure Boot state, and which kernel driver each network device uses. Nothing gets installed: the lab runs on a VM, which has no hardware that needs these drivers.

Before you start

The lab installs ubuntu-drivers-common (the ubuntu-drivers command) if it's missing; reset removes it again. Write your answers to the files in /root/lab-answers/, one item per line.

Tasks

1. Find out whether this machine needs any proprietary driver. Write yes or no to /root/lab-answers/1.
2. Find which component the NVIDIA 580 driver (nvidia-driver-580) and the Broadcom STA Wi-Fi driver (bcmwl-kernel-source) are in, and what Secure Boot state this machine is in. Write the two components on lines 1 and 2 of /root/lab-answers/2, and on line 3 enabled, disabled or no EFI.
3. For each network device, find the kernel driver in use. Write the drivers to /root/lab-answers/3, one line per network device.

Hints

• ubuntu-drivers devices prints nothing when every device works with open source drivers.
• apt-cache show PACKAGE | grep -m1 Section; mokutil --sb-state.
• lspci -k shows a Kernel driver in use: line under each network controller.
