Hi Joschi,

Thanks for the bug report. 

I just wanted to make a comment regarding the the "Desktop" Kernel
naming. 

The naming comes from in-Kernel locking changes that the Kernel
developers at one time thought might improve audio-video streaming as
one might use on the Desktop. This may be a bit unfortunate as its
confusing to many users and doesn't really improve things notably on the
Desktop ;)

In other words, if you use the Desktop Kernel, your scientific app
should be just fine, and its unlikely that you will notice any
difference in performance nor and difference regarding compatibility oir
drivers - all the same. 

Just thought I'd point that out.


Regards,

Sven
