Which DE for my parent's laptop (old Lenovo IdeaPad)? Wayland or X11?
I chose Debian 12 as a solid and stable base. Which of these shipped DEs is the best for this particular laptop series and Windows 10 like user experience?
Don't know the exact laptop model and year, but here are some specs: IdeaPad, only HDD, DVD drive, shipped with Win 8 or 10 (I think), unbearably slow on Win 10 currently
Use case: office, web, movies (not streaming), things for non-tech-savvy users
Personally, I'm using Arch btw with KDE Plasma 6 on Wayland, so I would prefer this over other DEs, but Debian still ships version 5. Has anyone experience with performance on an old Lenovo laptop with any of the listed environments?
Replace the HDD with SSD. It will run faster. You can configure any DE to look similar to windows, maybe Gnome to the lesser extend.
One think to keep in mind when choosing the distro, you have to support it.
Good luck.
GNOME is basically nothing like Windows, in fact KDE Plasma is much closer. Cinnamon isn't in OP's list of DEs, though it should be available as a pre-installed option for Debian based on what I see in their live ISO list. At that point, it would probably be better to go with Linux Mint though, given the target user. I assume OP would have their reasons for choosing Debian over Mint if they wanted to use Cinnamon, though.
