I run Xubuntu 18.04 on a Toshiba L505 laptop with an i5-430M CPU. Is there any way I can limit the maximum CPU frequency? This can easily be done in Windows 7 (by limiting CPU to e.g. 70%). Also, there is no "/sys/devices/system/cpu/cpu0/cpufreq/".

  • If you don't have that directory, then either your processor doesn't support CPU frequency scaling or it is disabled in BIOS. Does your computer have the new location? /sys/devices/system/cpu/cpufreq/policy0 , which should have legacy links from the old locations. – Doug Smythies Aug 13 '18 at 23:32
  • @DougSmythies That directory is empty. I looked into the BIOS (there are no options to set CPU frequency). – Sumac Aug 14 '18 at 6:06

You could try to install the Cpufreq extension (https://extensions.gnome.org/extension/1082/cpufreq/) which should give you a gui to set the cpu limits.

  • I am not using Gnome. – Sumac Aug 14 '18 at 5:49
