Why Ubuntu 12.04 LTS is broken for game(r)s

Ubuntu 12.04 has great potential - to be the greatest Linux desktop version for game(r)s and for a long time. 
Valve supporting it with their Steam client, and the nice Ubuntu store at that means it has great potential.


Game developers, want to target a stable (predictable) OS/platform.
As an example, Windows provides this - Windows XP has a life span of more than 5 years (supported by Microsoft with service packs etc).

Ubuntu 12.04 is an Long Term Support (LTS) version - it will be supported for 5 years.
But sadly - from an end user (gamer's) perspective - it's broken.

Canonical's move to extend the time for Ubuntu 12.04 to 5 years is a great initiative that could enable a competative Linux desktop platform in this aspect.

Now, on to the (fixable) problems!

 1. The way nvidia driver installations are (not) handled. 

Earlier Ubuntu versions did offer to install (or am I blind?) binary blob drivers where the kernel module was updated when the kernel was patched.

This is essential for games to run well - shaders and other advanced stuff is not handled well by the noveau driver (maybe on some cards, but we're talking mass consumption here).

While I like the idea of an open source driver, I honestly never think noveau will be good for anything other than providing 2D graphics during installations.

Installing nvidia's own driver is not easy for end-users, and Ubuntu made it even harder for experienced linux users because they do not supply kernel headers when updating the kernel.

        Conclusion: This totally breaks Ubuntu 12.04 for gamers.
        Can be fixed: Yes, please! 

2. Compositing is always enabled 

On Ubuntu 12.04 it can't be turned off - regardless of running something in full screen or not.

This is allegedly fixed in Ubuntu 12.10, but this really should be backported to 12.04 as it almost breaks the frame rate on simpler graphics cards like the Intel HD Graphics 4000.


        Conclusion: Ubuntu 12.04 is broken for gaming on most (all?) 2013+ laptops
        Can be fixed: Yes, please!

 3. Lack of UEFI boot loader support

Secure boot aside, new machines - mainly laptops from october 2012 and onwards can only boot from a UEFI partition.
BIOS is no more, and Ubuntu 12.04 can not successfully install to these machines. (It installs, but the UEFI ROM doesn't find it and can not boot).

        Conclusion: Ubuntu 12.04 itself is broken
        Can be fixed: Hopefully (not sure about kernel versions)

Summary

Pretty please... Canonical, fix this!!!
