DRIVERS
One of Ubuntu’s strengths is that “it just works” applies to hardware. It’s gone to great lengths to ensure that when you install Ubuntu, you’re not left trying to source (never mind install) key drivers.
Ubuntu even works with your graphics card or chipset with no problems, although if you plan to use your PC for gaming, you may have to investigate thirdparty alternatives—Nvidia and AMD users should open System Settings, and go to “Software & Updates > Additional Drivers.” After a short delay, choose the latest version marked “proprietary, tested,” click “Apply,” then reboot.
To add a printer, go to “System Settings > Printers,” and click “Add” to see if it’s automatically detected; follow the wizard to see if drivers are included. If not, visit the manufacturer’s website to see if there’s a Linux driver. If it’s a .deb package, installation is simple; if not, you may have to look for a .sh installer— ensure the file is executable (check “Allow executing file as a program” on the “Permissions” tab of the file’s properties in Nautilus), open Terminal, navigate to the file’s directory, and launch it thus:
$ ./filename.sh
