Nothing, at all.
Some things you can't do easily in Mint, like create snapshots automatically and boot into them when something breaks.
But it's all Linux and freely available software under the hood, and the lines between configuration, customization and forking your distro are blurry.
You can't have your entire system configuration in a repository of plain text files, which has lots of advantages, but it's not worth caring about unless you feel excited to get into it.
Why not? Isn’t this the whole concept of Bash Script, Ansible, Terraform, etc…
I mean it can be as simple as a git repo that pulls down an install script then syncs your dot files. What am I missing?
If you’re referencing Nix, you can also have that on Mint.
Yeah, I'm talking about not just Nix, but NixOS. Nix (the package manager) can do a lot, but NixOS + disko + home-manager can literally be all of the configuration for your machine from drive partitioning through to dot files. Throw in nixos-anywhere and impermanence and you can have an insane amount of control over all of your computers.
Ansible, Terraform, Chef, etc. do have some overlap, but the main difference is that those tools iterate through the system modifying it piece by piece and NixOS is declarative.
If something fails in some of my bigger Ansible playbooks, it could mean 30 minutes of just running through all the steps again. I could probably break it into sections, but then I have to worry about making sure they all get run when things get updated. In my NixOS install, it's way faster, I can roll back to a previous state, and troubleshooting is way easier in my opinion.
Serious answer? XFCE doesn't support multiple monitors with different refresh rates. So that.
Some of the other answers (like Meta (aka Windows Key) not working for shortcuts) can be hacked around, but unless you switch to a DE that supports Wayland, you will never have stable multi refresh rate differences on multiple monitors.
I'm not a fan of the xfce UX at all, and multi-monitor support still has a lot of issues (under Debian 12), but I am pretty sure having different refresh rates is possible
Use Pacman as your package manager, or something. Linux is Linux. If you use a mainstream distro it should be 90% similar to all other distros. You don't really have to worry about FOMO when it comes to Linux.
Compared to Arch(-based): Accesing the latest packages. It's not impossible, especially if you go for Debian testing repos, but it's definitely extra work.
Compared to special-purpose distros (i.e. gaming, portable, high security/privacy, pen-testing): Whatever their special purpose is will usually be harder to achieve.
Compared to huge corpo distros (SUSE/Fedora and derivatives): Ease of more intricate setups and maybe some security testing.
Compared to Ubuntu: Paying a corporation to not withhold security patches from you.
In my experience, not much, but I’m a marginally functional newbie. Mint manages things for you fairly nicely and has been the best, it just works with out messing with much/anything. (At least for my hardware)
I managed to get gnome working smoothly on mint and have been happy with it. I started and returned here since I last ditched windows as a native OS.
The only thing that has made me consider distro hopping from mint is AUR on arch and gnome, though I’ve been successful so far.
Part of trying the distros that are more advanced and give you more explicit control and configuration is the sense of accomplishment and it makes you figure out how and why things work the way they do. It holistically builds your velocity in your understanding of Linux. (Or gnu whatever that nuance is).
If your machine has enough resources it is super easy to host VMs of anything you want to try. You can try them all, and it won’t cost you anything but time!
If you feel like you need/want software from AUR you should check out Distrobox. It can run any distro on top of your installation using Docker under the hood, but it tightly integrates into your system so with little effort you can run AUR programs from your launcher as if they were natively installed on your Mint.
If you are speaking about stock Linux mint Xfce, with the default kernal, mesa version etc., your support for very new hardware - Arrow lake, battlemage and RDNA 4 will be imperfect. In general, very new hardware (launched within the last 6 months) will not be supported properly because the lts kernel being used was written before these products were launched
The ultra 7 is actually a good all rounder. Decent performance (well balanced between gaming and production workloads), good efficiency and good pricing with respect to the AMD options. AMD is of course better for pure productivity (9950x), pure gaming (7800x3d and the upcoming 9800x3d) and is better at the low end (7600, 7600x)
Steam and Lutris work well!
I can game on XFCE Mint just fine. I actually have an easier time of it than on a number of distros, thanks to the combination of flatpaks and the Ubuntu base.
But, I am not "the kids".
Reasons are usually just newest kernel/mesa/etc. Most of the time the difference is very small, and often inconsequential. However, every now and again there is a major development that might make it worth it (IE: The graphics pipeline that all but made dxvk-async obsolete)
If you are using Gnome distros: you can feel exactly what it feels like getting back to working in a restricted, overhyped, overbranded environment like Windows.
If you are using Ubuntu: you can get advertising during your system's software upgrades. No, really.
If you are using Arch: you can post aroudn the internet saying you use Arch btw.
Depending on the distro, you can use some alternative software stacks, but that's mostly the backend (eg.: systemd versus openRC, Apache vs Nginx, X vs Wayland); most "desktop app" level is mostly the same for each desktop environment, is kinda the point.
I had trouble using Flatseal to adjust permissions for Flatpak applications in Linux Mint. But that was a few months ago and may have been fixed. Other than that I never really had trouble with stuff being broken or unavailable in Mint.
I guess if you use very new hardware you might prefer a newer kernel than the one Mint uses. Or if you want the latest versions of packages, a rolling distro might suit you better. Or you might prefer a different filesystem. But if none of this bothers you, there's no need to switch. Mint generally works well.
