You don't get it: I want to be able to use BOTH when I need them. It's the same whenever you need to connect a projector: you don't want to turn your laptop's monitor off. You need per-monitor scaling and so you need Wayland (no good fractional scaling).

who say is not possible plasma+nvidia+privative drivers+wayland?

Why would I? Fractional scaling sucks on Linux, even on X11. Only QT supports it: even with GTK you have to play with font sizes etc.

Kernel has a CEC driver too, GPUs tend not to have the hardware for license cost reasons. For that reason game consoles have to use a separate chip to implement CEC HDMI. GPU board makers could do the same, but I'm not aware of any doing so, am I wrong? Deep colour is also supported by DRM/KMS drivers, it's mostly not supported by DEs due to lack of application/toolkit support AFAIK. Chicken and egg.
That being said, I don't know if Raspberry Pi would spend extra money on a CEC controller chip or license, but I do know CEC works on a SolidRun Cubox-i4Pro, a Raspberry Pi 3 and a Raspberry Pi 4 when those devices are connected via HDMI to a TV and use LibreELEC (minimalist Linux+Kodi mediacenter-oriented distro). AFAIK Raspbian also supports the feature.
There are certain things that Linux is perfectly capable of working with, but haven't been in the spotlight for "normal" desktop linux distros.
eg: GSM chip-based phone calls, until Purism's PureOS very recently decided that the OS would be essentially the same on their laptops and their linux smartphones (though compiled to ARM vs. x86-64, leveraging different bootloaders, etc)... now if you have a supported usb modem or such you can actually dial and talk from your PC.
Maybe CEC is just one of those things, even if the hardware is capable and the feature is fully implemented kernel-side? I know I would like having this feature on a HTPC if I currently had one, with proper configurations (because I might not want the HTPC to powerdown when the TV screen is switched off (eg: if it doubles as the home NAS)... CEC can be a great convenience but it can also be a curse sometimes.

Also if you're going down that road, what prevents you from setting up the screen resolution on a 4K screen/TV to QHD values instead of using UI fractional scaling? You would sacrifice the same thing (actual content rendering resolution) in favour of a more comfortable UI size, on a per-monitor basis without limiting your choice of hardware, right?
I find myself managing screen resolutions instead of fiddling with UI scaling all the time, even on Windows at work, and the blurriness is usually minimal (though I'm not the most demanding pair of eyes)... the real cost is UI realestate but if things are going to get tiny and unreadable, you're going to loose that regardless, and HiDPI+fractional scaling is actually only improving font and image crispiness, not usability, so IMHO it's a minor sacrifice.Last edited by marlock; 29 November 2022, 11:30 AM.
