[kde-freebsd] KDE Slows down X

[Paul Pathiakis]

Kris,

No GDM here.

Using default distro of PC-BSD 9.1-RC1 as install.  No recompilations or upgrades.

Using Nvidia GT5xx chipsets and Radeon 4xxxx chipsets.

KDE is running beautifully on 4 different desktops.  No CPU or resource issues.

P.

That helps me track this down. We use the same make options, so maybe
something else in how we run KDE is causing the issue. Anybody else
using GDM as the login manager?
