It would be a sad day for Linux audio if we were
forced to use bloated
desktops which were designed as direct equivalents for the proprietary
competition. I believe many audio users have little need for 3D
acceleration in the desktop, and the hot-running (and therefore noisy)
hardware it can require.
FWIW, I am already exploring Xgl and/or AIGLX, in part because I do like the
eye-candy, but more importantly because today I do not have to sacrifice 3D
acceleration (think: Pd + Gem) at the expense of noise. My home system as
well as studio uses 7600GS and GT cards which are fanless and without lead
(talk about health-conscious ;-). On top of that, even under current setup
which relies upon alpha/beta 3D X servers I am already enjoying the wonders
of accelerated desktop where moving a window does not cause spikes in CPU.
So, not all is bleak in the wonderland of 3D ;-)
