So I wanted to test Ubuntu 20 on old laptop I have and see if things will work. To my surprise, it does. It's not as swift as on new laptop, but considering the age (9 years?), it still works. There are no issues with drivers and everything works smoothly. Ubuntu 20.04 running on Lenovo X220 The only recommendation I would have is to allow different scale for different displays, but this can be achieved with choosing different resolutions. Little confusing, but at the end it works. One more thing - does it really need to use 1.3 GB of memory without running anything? For old systems this might be a little bit of issue.
