How to Edit Ubuntu's Blacklist

In Ubuntu Linux, device drivers are loaded into the kernel as modules. These modules are smaller pieces of programming code that are dynamically linked to the kernel. If you want to disable a module in order to load a new driver or disable a piece of hardware, you can add the module to the "blacklist.conf" file. This does not remove the module. Instead, it tells the kernel not to use it. If you want to use the module at a later date, you can simply remove it from the blacklist.conf file.
