Package: x-window-system
Version: 4.3.0.dfsg.1-12

The X window system in Debian Sarge by default renices X to a nice level of 
-10. While this is mildly helpful on a 2.4 or less kernel based system it is 
harmful to the behaviour of a 2.6 based system with the modified O(1) cpu 
scheduler design making it highly likely that ordinary audio applications 
will underperform (skip) during periods of heavy X usage. A nice level of 0 
will perform well enough with a 2.4 kernel and allows using a 2.6 kernel on a 
desktop gui without problems.

This is modified in a number of places when multiple display managers are 
installed (xdm, gdm, kdm), and I believe are all fixed with dpkg reconfigure 
but should not use nice -10 by default.

It should be 0 by default nowadays. Old installs should check their
/etc/X11/Xwrapper.config (and eventually the debconf database) if they
are still get -10.
