Twitter post by Daniel Feldman (@d_feldman): Linux is the only major operating system to support diagonal mode (credit [Twitter] @xssfox). Image shows an untrawide monitor rotated about 45 degrees, with a horizontal IDE window taking up a bottom triangle. A web browser and settings menu above it are organized creating a window shape almost like a stepped pyramid.

Another funny concept
Hmm yes, web dev horrors beyond my comprehension!
That, right there, is a perfect example of why folks need to stop trying to shoehorn web apps everywhere they don’t belong. It’s a use-case for a proper native mobile app if ever there was one.
even if it’s just mobile
you already have to handle landscape/portrait mode
now imagine having to handle angled
That’s why you should’ve just handled arbitrary rotations instead of inventing a finite predefined set of orientation “modes” in the first place.
Things get a lot easier in the long run if you aggressively look for commonalities and genericize the code that handles them instead of writing bunches of one-off special cases.
And this is why my webapp only renders properly on circular displays.
Mine only renders on moebius strips.
Peak evil - well done. How much is the extra fee to wrap a letterbox around the circle on a conventional aspect ratio?
There’s good money in this idea!
Personally I went for the globe display, because I figured that was a more globally applicable format.
true
however
everything would be fluid in the layout and you would need to set what should go on top of what. And having this feature doesn’t seem worth the hassle of making if work, or even using it.
Imagine trying to type in a ‘fluid’ keyboard
TBH tho, seems like a cool gimmick for some apps.
And that’s called Responsive web design
That’s called over-engineering for use cases that don’t and won’t exist. Please lecture us some more though.
You mean the browser handles alignment instead of every single web dev?
Yeah, but I don’t want to have an app on my phone for a store I go to once. I don’t give a fuck if the page is ugly.
That just means it shouldn’t be a native app or a web app, but instead should be a plain ol’ webpage that doesn’t try to do app-y things in the first place. The notion that web pages have any legitimate reason to know your viewport size (let alone anything at all about the screen hardware itself) is like one of those “statements dreamed up by the utterly deranged” memes, except not satirical.
Seriously: literally the entire defining principle of HTML (well, aside from the concept of “hyperlinks”) is that the client has the freedom to decide how the page should be rendered, but misguided – or megalomaniacal –
graphic designerswebmastersfront-end web “devs” have been trying to break it ever since.Lol - in your other comment you suggested that web devs key off of screen rotation to resize the page, but now you’re saying the client shouldn’t know anything about the viewport at all? Which is it? And why would the rotation angle be useful if I don’t know the aspect ratio of the screen? Or are we now assuming that widescreen will be a thing forever? I thought your ingenius idea was to be able to handle any use case.
Lol - in your other comment you suggested that web devs key off of screen rotation to resize the page, but now you’re saying the client shouldn’t know anything about the viewport at all? Which is it?
Legitimate apps key off screen rotation do fancy stuff. Web pages let the browser render them and don’t try to do fancy stuff. It’s not that fucking hard.
Follow up question, would it ideally work like the old Java Applets then, where you have to explicitly ask to launch a web app?
or a web app, but instead should be a plain ol’ webpage
I did not know about that distinction.
Hmm, so are there actual inadequacies in the browser-rendered standards that lead people to do this? I’d buy that it’s purely webpage sponsors wanting to be an all-powerful decider that controls what everyone sees and possibly thinks, but on the other hand I don’t know enough about browser rendering and page design to be sure. All my webpages are pretty spartan and scream “backend guy”.
It’d sure be nice if we could go back to circa-2012 with no popups or stupid bloat.
I sort of agree with you to a degree, but I also think that the browser having knowledge of the size of your viewport actually has some use. Now, I would probably like it more if all webpages were just made with the restriction of not knowing the viewport size since that would dictate some design choices. Cellphones can just scroll around the page anyways. They should be second class citizens on the internet anyway in my opinion. The smartphone has been one of the worst inventions for the human race with how much it seems to isolate a lot of people more than connecting them.
Huh? How’s this an example of web apps being bad?
The thread OP has an axe to grind against web devs because he thinks they’ve ruined the Internet.
This could totally be adapted into a game for a very interesting immersive experience. Imagine entire worlds of gameplay that adapted to the orientation of your viewport.
shoehorn web apps everywhere they don’t belong
Who is doing that? In my experience, “web apps” are on the web or occasionally on desktop and are fine. Slack for example, is a fabulous desktop app and has used web tech from day one to great success
VS code is an electron app, there are a few others that have a simple enough purpose that they shouldn’t be using a whole dedicated chrome engine to function.
Vs code is an exemplary app and supports what I’m saying. As far as others…what’s the right amount of complexity for using electron? Imo the maintenance advantages alone almost justify using it. It’s not appropriate for every app but slack and vs code are pretty stellar examples of how well it can work.
VS code is a good app in spite of using electron, not because of it. There’s no reason a simple plaintext editor needs to allocate 300MB of ram even without extensions just to launch, and there is definitely no reason a plaintext editor should require compiling chromium to build from source.
Slack is fine, but only when you exclusively use slack. Throw in an actual browser, discord, VS Code, Whatsapp, teams (?), etc. each with their own chromium instance and now your 16GB of ram are being eaten up at idle.
I mean yeah it’s a little heavy. Same trade off everyone makes every time they load a web app of any kind.
I run a lot of those apps concurrently and I don’t have issues with not having enough ram.
Why does this low key feel like something I would actually want to use
Yeah, I actually miss this sometimes, when I’m lounging in some weird position. The question is how much the keyboard would suck.
Like all of it.
I’d be awkward to hold at that angle.
No, holding it would be fine in some situations. It’s probably resting on a chair arm or something while my head is on the seat.
It’s okay, I’ll hold you at any angle x
Because you are not immune to propaganda.
The diagonal agenda is coming for your kids!!!
I hear that anti-geometrists are trying to get the pythagorean theorem banned in schools now.
ah yes, i’ve been propagandized into… wanting my phone to have a diagonal mode
there are very few things more politically neutral than this.
Congratulations. In almost 30 years, this is the first thing that finally made me want to throw my phone when I saw it.
Smart phones haven’t existed for 30 years…
I’ve had cell phones for 30 years. Never mentioned anything about them being smart the whole time.
What would you be able to see on a 30 year old cell phone that would make you throw it? A weird number?
i’d like to know what hallucinogen you’re on or neurological damage you have, as you keep responding to things i never said-- i never mentioned a 30 year-old cell phone.
So “in 30 years” you never wanted to throw your non existent cell phone. Your original comment just doesn’t make sense.
It doesn’t make sense to you, because something is very wrong with your brain.
Best of luck with that
Well now i wanna use it(probably works in linix phone?)
Linux phones aren’t supported because it’s an Xorg feature. Usually Linux phones use Wayland for the better (touch) experience. If someone wanted to they could implement it on a Wayland compositor, but given that no other OS I know of supports diagonal mode, I wouldn’t hold my breath.
Honestly though, I have an iPhone SE and holding it diagonally like that is pretty comfy. Could actually be on to something here.
Not familiar with an iPhone SE, assuming it’s a smallish phone?
Yes, more reasonably sized like iPhones used to be around the 6-7 generations.
I almost want it
They put touchscreens on doorstops now? /s
Java truly runs on everything.
Embrace the power of the pyramid.
Ackchuwally, that’s a prism 🙃
ackshuaelly, it says ‘pyramid’ right there
I’ve noticed… But it lies
Unleash the power of the pyramid!
BRB, sticking microcontrollers to the back of my monitors so I can use their accelerometers to report the orientations in real time…
I would love it so much if xrandr was able to keep up with that and didn’t blink for 3 seconds every time you changed orientation
Maybe a custom Wayland compositor could keep up
Now we need triangular windows that reshape in real time when you spin the monitor.
All of the screen elements should settle like sand in an hour glass, but using voxel physics in real time.
That’s would be brilliant. I’m guessing the monitor stands aren’t up for the extra usage they’ll get, though…
Well monitor stands need to keep up
If we can make windows that can reshape themselves to a shape-shifting 4D monitor, Rami-chan will finally be able to run Linux.
Not on wayland, right? Time to pester wayland devs to add this important missing features!
Probably would fall into scope of a compositer in Wayland, rather than the protocol. I suspect it originated with old CRT displays. Sometimes they can appear scan diagonally.
Even without that usecase, I think it’s great to have around in order to support novel displays and display-like devices.
How many minor operating systems support it? 🤔
There’s ReactOS and BSD off the top of my head.
Haiku counts
I think ToaruOS does? I remember reading something about it but haven’t managed to install it yet to verify.
Edit: found it
Why would you want this?
to display Java class names on a single line

What if your monitor has a bullet hole you want to avoid looking at?
Why does your monitor have a bullet hole?
Why do you ask so many questions? ಠ_ಠ
Why don’t you answer them?
Because then words like “evidence” and “premeditated” get thrown around.
Because asking and answering too many questions was exactly how they ended up with a bullet hole in their monitor.
American schools
I came back to my office after the new year’s break and a stray bullet, from I’m assuming celebratory gunfire, was shot through the wall and hit my screen. Admittedly it wasn’t a hole and the screen was totally unusable after, but I’ll be a close n=1.
You don’t?

A bullet hole would be slightly less annoying than the one green dead pixel I have at work.
Why would you not?
Can’t argue with that.
It’s a novelty. I for one deeply love unusually shaped monitors and UXs.
(insert image of Mt. Everest)
Because It’s There.
Could be useful for an interactive art installation or something alike.
Possibly to run those strangely shaped outdoor billboard signs
It could be useful if you live in a submarine that is always emerging/submerging.
I thought it was surely just a joke but looking at the devices to the right maybe this was due to limited desk space?
4th nerve palsy posse has been asking for this for years.
It’s not about why. It’s about the freedom to do.

How can you do fractional rotation? Does it only work with x11 or is it also supported in wayland?
Rotating the display by a custom angle is possible through xrandr on X.org.
There’s no Wayland protocol for custom angle rotation, and I don’t expect anyone to create a protocol extension without a use-case.
My wild guess: Theoretically it should be possible for a compositor to support similar custom rotation, as applications simply draw to their surface (window), without knowing how and where it is displayed on the viewport (display).
But it might require quite a bit of work, depending on the project, so I don’t expect to ever see custom rotation on anything besides smaller/niche compositors.
[1] https://unix.stackexchange.com/questions/552138/rotate-a-display-by-custom-angle#552140
There’s no Wayland protocol for custom angle rotation, and I don’t expect anyone to create a protocol extension without a use-case.
Puh-lease. It’s Wayland; the devs fully and honestly expect every app developer (eg.: calc, Libreoffice, notepad.exe) to implement custom angle rotation on their own.

[gestures at thread] Does this not count??? 😁
Seriously, though: I suspect there might be non-novelty use-cases in mobile devices, especially things like smart watches. Those aren’t beyond the scope of Wayland in the long run, are they?
Ok I was joking with the images but now that I think about it this would likely be pretty useful to have on smart watches with circular displays.
E.g. having the watch face rotating to face towards the wearer would be a pretty neat concept. Definitely something I’d want a toggle for though.
Smart watches tend to be microcontroller class devices because even though you can fit something powerful in there, powering it and heat dissipation make it silly.
The usual embedded-type application for wayland that it’s even especially designed for is automotive: Things without window management but not particularly hardware-restrained. Also think public transit ticket machines, ATMs, such things. In that sense, from wayland’s perspective android is already desktop.
in wayland the compositor is king they can do mhatever they want with the screen

I was looking into this earlier to try fixing a display that was being offset on an old tv screen. The display was going off the left side of the TV, causing a black bar on the right side.
I was trying
xrandr, and fixed it somewhat by offsetting the display back, but somehow it did not fix the right side - it seemed as if the display had went under the black bar.But yeah you can offset, stretch, skew and rotate with
xrandrThe
--rotate normal,inverted,left,rightdoes not work, but you can use the transform option to achieve the same effect. To create the transformation matrix you can use something like: https://angrytools.com/css-generator/transform/- for translateXY enter half the screen resolution
- don’t copy the generated code, it has the numbers in the wrong order just type out the matrix row wise.
The final command looks like this:
xrandr --output screen-1 --transform 0.87,-0.50,960,0.50,0.87,540,0,0,1To restore the original use (type this in first, because if you screw up you might not be able to see anything anymore):
xrandr --output screen-1 --transform 1,0,0,0,1,0,0,0,1I tested it on x11.
Did you check the actual TV settings? Some of them let you adjust where picture is displayed iirc.
It only had two modes for the VGA source, 16:9 and 4:3. The 16:9 is the right ratio for the laptop but had the offset issue. The 4:3 makes it stretched out / squashed, but it doesn’t have the offset issue.
Ha~! WebDevs haven’t cared about desktop for years.
Product owners, you mean. They are the ones that determine support level of browser and as a result, what testers focus on. Devs don’t focus on things that aren’t a priority because otherwise they’re working on that on the evenings and weekends free of charge.
I remember seeing the video of this. The guy was doing it for shits and giggles, but it ended up looking great!
Can you link it?
No idea what it was, sorry. One of the youtube recommendations at the time.
I won’t try implement something like this even my boss forces me.
No one does this kind of stuff because someone asked them to do it. This is the kind of useless, insane stuff you do for the lulz, or because someone dared you.
I hate this.

Basically, it’s just some cool X11 magic that uses a matrix transformation to rotate the screen.
