Instead, get a second-hand monitor, a cheap keyboard and mouse combo, and a USB speaker, then install a multiseat app. If you already have a decently powerful computer and need two devices for general use, like internet browsing and general productivity, you don't have to shell out a lot of money for a new computer. So if one of the users needs Linux while the other user needs Windows, you can opt for this solution instead.

It's also useful for other applications, like running multiple operating systems on one computer.

However, it's free for personal use, so you don't have to spend just to get it running. It also consumes more computing power compared to dedicated multiseat apps. On the other hand, the VMWare Workstation Player isn't easy to set up and requires additional licenses for each software you install per user. You can test out the ASTER app for one month, but you will have to pay for it afterward. The primary disadvantage to this option is that it isn't available for free for personal use. When you turn your computer on, it will automatically launch, so the users can start using their assigned computer without additional setup. Once it's installed, it will automatically detect each monitor connected to your computer, and it will then create an individual desktop for display. Multiseat apps are generally easier to set up and use. You can use a dedicated multiseat app like ibik ASTER or a virtualization engine like the VMWare Workstation Player. Once you've added the peripherals you need for all users, the next thing you need is to install a multiseat app.
