None of this puts the user out of control; they’re free to add the Flatpak repository should they wish to do so.

which these suggested Fedora Spins are designed to integrate with as tightly as possible

Could you explain what exactly this “tight integration” pertains? AFAIK these are just regular old global-state distros but with read-only snapshotting for said global state (RPM-ostree, “immutable”).
Read-only global system configuration state in pretty much requires usage of Flatpak and the like for user-level package application management because you aren’t supposed to modify the global system state to do so but that’s about the extent that I know such distros interact with Flatpak etc.

Bazzite is completely the opposite of an OS designed to run one app at once, which means you haven’t tried it before rubbishing it as a suggestion.

That is their one and only stated goal: Run games.

I don’t know about you but I typically only run one game at a time and have a hard time imagining how any gaming-focused distro would do it any other way besides running basic utilities in the background (i.e. comms software.).

Obviously you can use it to do non-gaming stuff too but at that point it’s just a regular old distro with read-only system state. You can install Flatpak, distrobox etc. on distros that have mutable system state too for that matter.

Could you point out the specific concrete things Bazzite does to improve separation between applications beyond the sandboxing tools that are available to any distribution?

It’s true that I haven’t used Bazzite; I have no use for imperative global state distributions and am capable of applying modifications useful for gaming on my own. It’s not like I haven’t done my research though.

“No your honour, we do not offer users any patented software, we merely ship a system which directs users to this other totally unrelated entity that we are fully aware ships patented software.” will not hold up in court.

I also imagine RH would simply like control over the repository content they offer to users by default. Flathub acts more like a 3rd party user repository than a “proper” distro.

I don’t assume you to be stupid, so lack of information is the most likely explanation for not knowing what “it” refers to here.

Read the linked issue first perhaps.

Offering patented software would open Fedora (a RedHat product mind you) up to legal issues in places that know software patents (primarily the U.S.).

There is no distribution that does what you’re looking for. All the ones recommended by others in this thread are just generic distributions that do nothing special to separate user applications and I have no idea why they saw fit to mention them at all.

The best recommendation here is Qubes but that’s arguably not a distro but rather its own operating system that can then run some instances of distros inside of it with strong separation between those units.

The only thing that somewhat goes the direction you want is Flatpak but it’s not anywhere close to Androids really quite solid app separation scheme.

The reality of it is that most Linux desktop apps are made with the assumption that they are permitted to access every resource the user has access to with no differentiation; your SSH or GPG private keys are in the same category as the app’s config file.

Standard APIs to manage permissions in a more fine-grained manner are slowly being worked on (primarily by the flatpak community IME) but it’s slow and mostly focused on container stuff which I’m not convinced is the way forward. There does not appear to be any strong effort towards creating a resource access control design that’s anywhere near as good as Android’s in any case though.

The closest thing we have is systemd hardening for system components but that’s obviously not relevant for desktop apps. It’s also (IMHO) inherently flawed due to using a blocklist approach rather than an allow-list one. It’s also quite rigid in what resources it controls.

I’m not convinced any of the existing technologies we have right now is fit for a modern user-facing system.

Here’s what I think we ought to have:

• A method to identify applications at runtime (e.g. to tell apart your browser from your terminal and your editor at runtime)
• A generic extensible way to declare resources to which access should be controlled within a single user context (i.e. some partition of your home filesystem or some device that your user generally has access to such as your camera)
• A user-configurable mapping between resources and applications; enforced by kernel-level generic mechanisms

No need for any containers here for any of this; they’re a crutch for poor legacy distro design that relies on global state. I don’t see a need for breaking the entire UNIX process model by unsharing all resources and then passing in some of them through by overly complex methods either.

Eventhough they’re quite simple and effective, I’m not convinced UNIX users are a good primitive to use for application identification like Android does it because that implies user data file ownership needs to be managed by some separate component rather than the standard IO operations that any Linux apps ever uses for everything.
I think this should instead be achieved using cgroups instead which are the single most important invention in operating systems that you can actually use today since UNIX IMHO.

The missing parts are therefore a standard for resource declaration and a standard and mechanism to assign them to applications (identified via cgroup).
I haven’t done much research into whether these exist or how they could me made to exist.

That is not relevant here in any way. That’s a distro made to easily run one app at a time without really caring about data security w.r.t. that app.

First of all you need to figure out which sensor this even is. On my nct6687, there’s a sensor on the PCIe slot that is constantly >90° and that appears to be totally normal.

From Windows

Low-latency VRR that works correctly

It does not feel quite right in kwin and the rather new “proper” support in Hyprland doesn’t feel right either.

In hyprland you actually have to enable a special option and set a lower bound for VRR because it doesn’t handle LFC with cursors, so a game running at 1fps will make your cursor jump around once per second which is totally unusable. With LFC that would typically result in at least e.g. 90Hz.

VRR in other apps works quite well though. I’m not sure how intended it is but it allows for some nice power savings on my Framework 16; when it’s just a terminal refreshing a few times a second, the screen goes all the way down to 48Hz and when I actually scroll some content or move the cursor it’s still buttery smooth 120Hz.

Sway feels very good w.r.t. VRR but it cannot handle cursors at all (visible or invisible): whenever you move the mouse, VRR is deactivated and you’re at full refresh rate until you stop moving the cursor. It might also not be fine because I could only test a racing game due to the mouse issue and it’s so light that it always ran at a constant rate, so that’s not a great test as what differentiates good VRR from bad VRR is how varying refresh rate is handled of course.

Xorg VRR also never felt right; it felt super inconsistent. Xorg is also dead.

VRR is fundamental for a smooth gaming experience and power efficient laptops.

From macOS

Mouse pad scroll acceleration.

If you’ve ever used a modern macbook for a significant amount of time, you’ll know that its touchpad is excellent. I’d actually prefer a macbook touchpad over a mouse for web browsing purposes.
On Linux however, it’s a complete shitshow and the most significant difference is not hardware but software. You might think that, surely, it can’t be that bad. Let me tell you: it is.

Every single application is required to implement touch pad scrolling on its own; with its own custom rules on how to interpret finger movement across the touch pad. I can’t really convey how insane that is. There is no coordination whatsoever. Some applications scroll more per distance travelled, some less. Some support inertial scrolling, some don’t. Some have more inertial acceleration, some less.

Configuring scrolling speed (if your compositor even allows that, isn’t that right Mutter?) to work well in e.g. Firefox will result in speeds that are way too quick for the dozens of chromiums you have installed and cannot reasonably configure while making it right for chromiums will make it impossible to use forwards/backwards gestures in Firefox and applications that don’t implement inertial scrolling at all (of which there are many) will scroll unusably slowly.

It’s actually insane and completely fucked beyond repair. This entire system needs to be fundamentally re-done.

There needs to be exactly one place that controls touch pad (and mouse for that matter) scrolling speed and intertial acceleration, configurable by the user. Any given application should simply receive “scroll up by this much” signals by the compositor with no regard for how those signals come to be. My browser should never need to interpret the way my fingers move across the touch pad.

Accel key

Command/super is just a better accel key than control. Super is almost entirely unused in Linux (and Windows for that matter). Using it for most shortcuts makes it trivially possible to make the distinction between e.g. copy and sending SIGTERM via ^C in a terminal emulator. No macOS user has ever been confused about which shortcut to use to copy stuff out of a terminal because CMD-c works like it does in any other program.

It also makes it possible to have e.g. system-wide emacs-style shortcuts (commonly prefixed with control) and regular-ass CUA shortcuts without any conflicts. C-f is one char forwards and CMD-f is search; easy.

Unified Top bar/global menu

Almost every graphical application has some sort of menu where there’s a button for about, help, preferences or various other application-specific actions. In QT apps aswell as most fringe UI frameworks, it’s placed in a bar below the top of each window as is usual on Windows. In GTK apps, it’s wherever the fuck the developer decided to put it because who cares about consistency anyways.

For the uninitiated: On macOS there is one (1) standardised menu for applications to put and sort all of their general actions into. It is part of the system UI: almost the entire left side of the top bar is dedicated to this global menu; populated with the actions of the currently focussed application.

If you’re used to each application having this sort of menu in the top of its window, having this menu inside a system UI element that is not connected to the application instead will be confusing for all of 5 seconds and then it just makes sense. It’s always in that exact place and has all the general actions you can perform in this application available to you.

There is always a system-provided “Help” category that, along with showing macOS help and custom help items of the application, has a search function that allows you to search for an action in the application by name. No scouring 5 different categories with dozens of actions each to find the one you’re looking for, you just simply search for the action’s name and can directly execute it. It even shows you where it’s located; teaching you where to find it quickly and allowing for easy discovery of related functions.

When you press a shortcut to execute some action in the app, the system UI highlights the category into which the executed action is organised; allowing you to find its name and (usually) related actions.

Speaking of shortcuts: When you expand a category, it shows the shortcut of every action right next to the name. This allows for trivial discovery of shortcuts; it says it right there next to the name of the action every time you go and use it.

This is how you design a UI that is functional, efficient, consistent and, perhaps even more importantly, accessible. Linux should take note.
