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.
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.
- Because you are not immune to propaganda.
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.
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...
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?
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 🙃

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

Linux is the only major operating system ~~to support diagonal mode~~

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...
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? 🤔

I'm assuming most that can run Xorg.
- Correct
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
- This person gets it
What if your monitor has a bullet hole you want to avoid looking at?
- Why does your monitor have a bullet hole?
- A good use case for American k-12 IT admins
- 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
in case you use a pear phone as a daily driver
I thought it was surely just a joke but looking at the devices to the right maybe this was due to limited desk space?
It could be useful if you live in a submarine that is always emerging/submerging.
4th nerve palsy posse has been asking for this for years.

Finally, Peewees Playhouse has found open source representation.

Jambi is GNU

Who hurt you

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.

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.

- 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?
in wayland the compositor is king they can do mhatever they want with the screen

- Time to ask the wayfire devs to implement fractional screen rotation.
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 xrandr
- The --rotate normal,inverted,left,right does 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,-0.50,960,0.50,0.87,540,0,0,1
  To 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 1,0,0,0,1,0,0,0,1
  I tested it on x11.
- Did you check the actual TV settings? Some of them let you adjust where picture is displayed iirc.

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.

What has science done?

There's no science here.

a great prank for computer labs... just rotate everything by 0.5 degrees...

Yeah, keep adding 0.5 deg every minute or so.
- Add a randomizer that has a chance of resetting it back to normal every now and then for maximum chaos
