"No. What Linux needs is more and better video drivers."
The problem isn't the video drivers, it's the massive hoops that extensions must work through in order to work implement 3D in X11's 2D based framework. A simple example - user clicks at 10x10 on the screen. What widget is under 10x10 in a desktop where surfaces may be scaled, semi transparent, animated? X11 has no idea. It can't translate coords, it doesn't have anything equivalent to a GL picker to figure it out. This seriously impedes the kinds of things you can do even with a compositor extension.
"If you run off the rails and abandon the best X drivers, then you start from scratch sending the entire desktop back to the mid-90s. It doesn't matter how much you've overwrought the plumbing. The total lack of acceleration of everything from 2D to 3D to video playback will kill you."
Utter nonsense. You're not starting from scratch at all. Open source and proprietary drivers already and exist and work in the absence of X11 and through DRI. How do you think DRI happens you nitwit?
"Context switching is nothing for a Unix to be afraid of."
Yes it is. It kills performance. If you have to pass between 2 processes (X server & compositor) then you incur a substantially larger roundtrip than doing it in inprocess. Messages have to be marshalled, scheduler interrupts must occur, pipelines and CPU caches get flushed. It takes far more time than doing it locally where it could occur in a single timeslice. It might not look like much for one call but this is potentially hundreds or thousands of calls. Anyone who has ever done RPC would understand this.
"Idiots that push this Wayland nonsense should be subjected to what they advocate while leaving the rest of us to not suffer their stupidity."
Idiots who push this Wayland nonsense are people who have actually bothered to read the technical issues and understand them.
Why don't you go read what the problem is and how Wayland attempts to fix it:
Frankly I find it laughable that some people get so defensive of any criticism of Linux that they can't recognize a practical solution to an obvious problem. X11 simply is not suitable for compositing or 3D effects. The extensions that exist are merely bandaids to the fundamental problem.
Wayland isn't a free ride (QT and GTK need to be ported to support it for example), but the payoff is enormous. Ubuntu are to be congratulated for biting the bullet to do something which should have been done a long time ago.
