Description:
hallo, cpu freq files in dir /sys/devices/system/cpu/cpu0/cpufreq

I cannot scale it by applet in E17, but after executing e.g. "cpufreq-set -c 0 -f 800", the applet starts work

Additional info:
* cpufrequtils 005-2
* config and/or log files etc.


Steps to reproduce:
start system try scale CPU speed by e.g. echo > file
exec cpufreq-set
and try file again
This task depends upon

Please provide more information if any, like relevant log and kernel messages.

You are execute these commands as root? Are you on i686 or x86_64, can you read files on /sys/devices/system/cpu/cpu0/cpufreq/*? What values are on? What relevant modules are loaded before and after don't work/work ?

Thanks.

I've started it after boot and after start E17 from console (as root)

And there is strange beahavior. After run that command "cpufreq-set -f 800MHz"
scaling works (by writing to file by applet)

I think, this is problem of applet in E17, in GNOME applet it works, I will investigate it

  • Field changed: Summary (cpufreq proc files have no write permissions → [epplet-base] cpufreq applet doesn't work)
  • Task reassigned to Eric Belanger (Snowman)
this is related only to cpufreq E17 applet. assigned to epplet-base maintainer
