A system administrator wants to try different parameters for the bluetooth kernel module without rebooting the system. However, any attempt to unload the module with modprobe -r bluetooth results in the following error:

modprobe: FATAL: Module bluetooth is in use.

What is the possible cause for this error?

Module bluetooth is being used by a running process. The system's Bluetooth service is currently not working. A device is currently re-connecting via Bluetooth and using the bluetooth kernel. The bluetooth module is being used by headphones.

Suppose an operating system is unable to boot after adding a second SATA disk to the system. Knowing that all parts are not defective, what could be the possible cause for this error?

The operating system must be reinstalled to recognize the second SATA disk properly. The SATA cable of the first disk needs to be replaced with a higher-speed cable to match the new disk. The boot device order should be configured in the BIOS setup utility, otherwise the BIOS may not able to run the bootloader. The power supply is not providing enough voltage to the new SATA disk, preventing the system from booting.

Suppose you want to make sure the external video card connected to the PCI bus of your newly acquired desktop computer really is the one advertised by the manufacturer, but opening the computer case will void the warranty. What command could be used to list the details of the video card, as they were detected by the operating system?

Using the command lshw, you can get detailed hardware information, including the video card connected to the PCI bus. The command dmidecode can be used to retrieve hardware information including details about the PCI devices. Executing the command hwinfo --gfxcard will provide detailed information about the graphics card connected to the system. Command lspci will list detailed information about all devices currently connected to the PCI bus.
