I would like to get a general picture about
Vendor closed source videocard drivers, Mesa drivers and OS update relationship.
I have a bit old gamer laptop, which has an ATI X1600 video card,
and i use it to develop OpenGL demos, frameworks, my game-engine.
I learned that Mesa driver is actually emulates OpenGL, so it cannot provide the same good performance that vendors (ATI, Nvidia) closed source drivers can.
So why not to install the closed source driver, right ?
There is no problem if you have the newest hardware,
the vendor will probably provide the closed source driver for it,
so you can download & install it on Ubuntu, then have fun.
The problem is if your hardware a bit outdated but still want to use it.
You have an up to dated Ubuntu (10.10) and its X window server (?)
is not compatible anymore with the old closed sourced driver.
I learned it from forums, that i should switch back to Ubuntu 8.x
if i want to use the OS with closed source driver.
Iam just wondering. What if i buy now the latest hardware which i want to use for years in the future, and still want have the most recent Ubuntu on it ?
One day in the future the Ubuntu will upgrade itself and saying,
that "sorry, but my X window system is no longer supporting your closed source
driver therefore i install the Mesa driver"
Could anybody describe the roadmap,
how it works in long term.
