The diversity of Linux distributions is one of its strengths, but it can also be challenging for app and game development. Where do we need more standards? For example, package management, graphics APIs, or other aspects of the ecosystem? Would such increased standards encourage broader adoption of the Linux ecosystem by developers?
Each monitor should have its own framebuffer device rather than only one app controlling all monitors at any time and needing each app to implement its own multi-monitor support. I know fbdev is an inefficient, un-accelerated wrapper of the DRI, but it’s so easy to use!
Want to draw something on a particular monitor? Write to its framebuffer file. Want to run multiple apps on multiple screens without needing your DE to launch everything? Give each app write access to a single fbdev. Want multi-seat support without needing multiple GPUs? Same thing.
Right now, each GPU only gets 1 fbdev and it has the resolution of the smallest monitor plugged into that GPU. Its contents are then mirrored to every monitor, even though they all have their own framebuffers on a hardware level.
So this is why multi monitor support has been a never ending hot mess?!
Yes and no. It would solve some problems, but because it has no (non-hacky) graphics acceleration, most DEs wouldn’t use it anyway. The biggest benefit would be from not having to use a DE in some circumstances where it’s currently required.
This right here is why i moved to a single display setup.
