http://ubuntuforums.org – Hello, I bought an HP-DM1 with SU2300 celeron core2duo CPU. unfortunatly, I was unable to activate frequency stepping (acpi-cpufreq or whatever). the SU2300 is supposed to integrate Enhanced Intel® Speedstep Technology so it should work. when I add the gnome applet, it tells me that cpu frequency scaling not supported anyone has a clue?
