[ubuntu-studio-devel] kernel vs DE WAS:Re: Feature Spec discussion: ubuntustudio-desktop

[lukefromdc at hushmail.com]

That's exactly what I am saying. It was a pre-release version of US I was 
playing with, but with the move from a Raring based to a Saucy development
version the rt kernel had a broken video driver (radeon r600).  If that driver
is working in current rt kernels that issue may have come and gone, but 
the fact that it got out at all means that the rt patch set has broken drivers
before and could do so again.

Since I edit video, the rt kernel is not needed for my normal workflow and is
not installed in my normal operating system
