Limit interface betyder (så hvidt jeg har forstået) at man kan sætte en øvre grenste for hvor hurtigt cpu'en køre. > sslug@sslug:~$ cat /proc/acpi/processor/CPU1/info > processor id: 1 > acpi id: 1 > bus mastering control: yes > power management: no > throttling control: no > limit interface: no Det her er ikke en seperat CPU men bare en representation af "den anden halvdel" af en dualcore CPU. Den kan ikke limit eller throttle for sig selv (følger altid CPU0's indstillinger). > Er powernow-k8 ikke noget som kan styre cpu-forbruget og dermed > strømforbruget? > Jeg har tilsyneladende ikke noget "power management" installeret. > Hvad kan jeg gøre? Og hvad er "throttling control"? Ubuntu burde understøtte throtteling som standart, prøv eventuelt at tilføje CPU frekvens appletten til dig gnoma panel. programmer som powernowd og cpufreq er forældede, da linux kernen nu selv kan stå for styringen af cpu frekvens styring. Set kræver bare at det rigtigt kernel modul er indlæst... Se evt her: http://ubuntuforums.org/showthread.php?t=248867 - Lasse
