Version: (using KDE KDE 3.2.1) Installed from: Debian testing/unstable Packages The KLaptop Daemon does not report the CPU frequency properly. The it relies entirely on the info in /proc/cpuinfo which only reports the maximum CPU speed but not the current one on kernel 2.6. The actualy frequency is reported on different places in either proc or sysfs. namely: /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed or /proc/sys/cpu/0/speed Therefore the display of the current cpu frequence shows a wrong value if power management and speed scaling is used. forwarded from: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=244317

Both interfaces don't have more accurate information than /proc/cpuinfo (at least after it has been fixed in 2.6.5). So I don't see a point in supporting these additional interfaces just as a workaround on a few early 2.6 kernels.
Comments from the original reporter: As Volker suggestet, the problem indeed is fixed at the 2.6.5 kernel. The frequency now is correctly reported in the klaptop applet. Again sorry for the false warning. And thanks for the fast responses. Werner Punz
