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
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.
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: 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.
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.

[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?
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.

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.
In Canada, the Ministry of Health pays colleges to teach kids COBOL and JCL. It’s a steady job, pension, good bennies. I know a handful of people who went that route, rather than the riskier private sector.
Would you happen to know how that compares to saying “Fuck it” and going with a Java career for the relative predictability? I’m not asking for any particular reasons, just curious.
I know some Java folks, but my sampling is biased because I meet them where I work - places that predominantly use the younger languages. Actually, I happen to know that the MoH in particular (and probably lots of other institutions) wrap their COBOL/JCL in a lot of Java, so that most devs never need to dive into the “real backend” if they want to just stay at the Java level.
Java people seem like family people. But from what I’ve observed, their job doesn’t seem any different. You can work in javascript, or python, and still insist on clocking out at 16, 1700. But I only work at startups or seat of your pants kinds of places, so I know about what I hear. 🤷
I mean, in the era of VHS this won't work because ultimately you're fast forwarding and rewinding. So you're gonna watch it anyway. but in the digital era I thought this would be what any Police officer did?
Like... they're not even gonna spend 10 minutes on a theft?
I got to that once, on mobile I’ve never worked out the rule for when FF opens a new tab vs opening a site in your current tab. They just kind of silently accumulate.
So do I, for a few days. If I haven’t read it by then, I’ll either bookmark for later or just close. I pretty much never have more than 10-15 active tabs ever.
Rust: You declare the castle type as unsafe and then search for a crate with a rescue_princess function. You discover the princess you rescued is a femboy wolfkin named Pawws. You now have pubic lice and an inexplicable smug sense of superiority.
