Ordinary modifiers are normally straightforward, in that they are additional keys that are held down as you type the main key. Control, Shift, and Alt all work this way (by default). However, some modifiers are ‘sticky’, where you tap their key once to turn them on and then tap their key again to turn them off. The obvious example of this is Caps Lock (unless you turn its effects off, remapping its physical key to be, say, another Ctrl key). Another example, one that many X users have historically wound up quietly cursing, is NumLock. Why people wind up cursing NumLock, and why I have a program to control its state, is because of how X programs (such as window managers) often do their key and mouse button bindings.

I always have an applet in my KDE panel that shows me if I have any sticky modifiers enabled without realising it. On some of my keyboards, this isn’t always easily noticable, especially when you’re focused on what’s happening on your display. A little icon that only shows up when a sticky modifier is engaged solves this problem, as it immediately stands out in your peripheral vision.

X Server is slowly being deprecated in the Linux world and being replaced Wayland. Still X11 is an interesting protocol to look at from the perspective of binary communication and management of resource which require fast speeds.

In this post I tried to cover basic information and create a simple but working app that is simple, defined in single file and easily compiles. No external code except libc was used. I find it fascinating when you can open black boxes and see how gears move each other.

As much as the time of X has come and is now finally in the process of going, it’s still an incredibly powerful set of tools that even in a bare state can do way, way more than you think. X has come with its own window manager – twm – for decades, and it includes several basic applications like xedit, xclock, xterm, xeyes. Twm is actually pretty cool, and includes some features, like iconify to desktop, that I wish still existed in modern desktop environments. It’s quite bare-bones, though, and I doubt there’s anyone out there unironically using it today.

As the linked article notes, even without advanced, complex libraries, toolkits, desktop environments, and so on, it’s entirely possible to create fully functional windows and applications with X. Of course, this makes perfect sense and shouldn’t be surprising – it’s the X Window System, after all – but you so rarely hear or read about it that you’d almost forget and just assume something like GNOME or KDE is an absolute requirement to use X.

Earlier this year, we talked about Niri, a very unique tiling window manager for Wayland that scrolls infinitely to the right. I’ve never seen anything quite like it, and while it seems polarising, I think it’s absolutely worthy of a dedicated niche. The project’s got a major new release out, and there’s a lot of improvements here.

First and foremost, virtually all animations have been overhauled, and new ones have been added for almost every kind of interaction. The videos on the release page do a really good job of highlighting what they’re going for, and I think it looks great, and for the animation-averse, every individual animation can be turned off. Niri now also supports variable refresh rate, and the IPC mechanism has been improved. Among the smaller improvements is a welcome one: when using the touchscreen, the mouse cursor disappears.

I really think this one has to be tried before judged, and I’m seriously contemplating setting up a Wayland environment just for this one, to see if it works for me. My window “flow”, if that makes sense, is already left-to-right, so the idea of having that effectively automated with an infinite canvas sounds very appealing to me, especially on smaller displays. I just need to figure out if it works in reality.

Miracle-wm is a Wayland compositor built atop of Mir, and its core is a tiling window manager like i3 and sway. It intends to offer more features compared to those, though, gunning more for swayfx. The project, led by Canonical’s Matthew Kosarek, recently released version 0.2.0, which comes with a bunch of improvements.

It supports sway/i3 IPC now, so that it can function in conjunction with Waybar, a very popular tool in the build-it-yourself Wayland window manager space. There’s also a new feature where individual windows can live on top (Z-axis wise) of the tiling grid, where they work pretty much like regular windows. Another handy addition is that the configuration can be automatically reloaded when you change it.

Miracle-wm comes in a snap package, but rpm and deb will arrive in a few days, as well. As the version number suggest, this project is in heavy development.
