Public bug reported:
Binary package hint: xserver-xorg-video-intel
Since I upgraded to jaunty, the cpu is busy at 50% on my core2 duo
system, mainly due to xserver and dbus-deamon: multiload applets shows a
systematic 50% processor use, even if no user app is active.
Even if I remove multiload applet and close gnome-system-monitor, top
keep showing a lot of use by xorg and dbus-daemon.
