Hello, I got almost for free a Lenovo laptop: CPU Intel i3 8130, 4Gb RAM. I would like to use It to learn Linux. I saw some people using Arch to learn the inside out of Linux, but I’m afraid It could be to challenging. What do you suggest? What Is the best way to learn? Thank you. Edit: First of all I thank you all for your suggestions, I think that this is what makes this community special. I installed Fedora Xfce for now and I worked all evening to male it work and customize it. I’m learning a lot already. I’ll move to Arch as soon I’ll feel comfortable with Fedora. Thank you all again.
I suggest Linux Mint. It has GUIs for almost everything and it’s very stable. With a little bit of tinkering of the services at startup, you can get Mint to run at 700 MB of RAM (as read via htop), instead of its default ~1 GB of RAM. That could be important to fit it better at 4 GB of ram with some demanding browsing.
I disagree with anyone who might suggest Fedora or Ubuntu with 4 GB of RAM. These distros require about 2+ GB of RAM to boot up, double than that of Mint.
Then there are the distros meant for older machines that use less ram, but it’s a shame to use these when your laptop is fast-enough with an 8th gen cpu (comparatively to very old machines, that is). Your CPU scores 3500 points on the passmark cpu benchmark which is enough for any kind of distro. 15 years ago, the average laptop cpu was 600 points (and Linux still runs fine on these with something like Debian/Xfce).
The lowest ram usage I’ve seen with a full-fledge modern distro/DE, is XFce with endeavourOS. I load it at 490 MB of RAM (it takes 630 MB on Mint for the same layout/apps).
Basically, your challenge is the RAM, not the CPU or the drive. Use an appropriate distro for the RAM and the difficulty you want, and always be mindful to not have too many tabs/apps open at the same time.
