coverup Posted August 17, 2006 Report Share Posted August 17, 2006 uname -r will tell you exactly what kernel your laptop is running. To set up speedstepping you need to load a kernel module, like speedstep_centrino or an equivalent for P4 processor, and a daemon such as powernowd, cpudyn or cpufreqd. Please post more details about the laptop and linux distro, and somebody will be able to give you a more concrete advise. Quote Link to comment Share on other sites More sharing options...
lavaeolus Posted August 18, 2006 Report Share Posted August 18, 2006 (edited) since I'm not sure which Linux you use, I don't know if it works for you but in Mandriva 2005 and 2006 everything you need is included, you need to have a working ACPI and a running cpufreq service (in mandriva control center/system/services acpi, acpid and cpufreq must be set to start at bootup and they must be running, then everything is basically ok (normally they should be already installed) on Mandriva you need only to install the powernowd-rpm (although it is named after AMD's PowerNow it works very well with Intel Pentiums too), powernowd is a userspace-tool, in gnome you can use the cpu-frequency-applet to see if it works and to set your cpu-frequency in KDE you can use klaptop to control your cpu-frequency by using the different performance profiles, if you have gkrellm and gkrellm-plugins (the actual plugin is gkx86info) installed you can see your actual cpu-frequency on ubuntu it basically works the same (here the packages are just debs intsead of rpms) Edited August 18, 2006 by lavaeolus Quote Link to comment Share on other sites More sharing options...
