I'm using Linux Mint. My laptop has a Corei5 CPU. When I check the system monitor, it shows that the CPU 1 usage is between 90 to 100% and CPU 2,3,4 are less than 5%. why it doesn't balance processes onto all cores? Because of high CPU 1 usage, the fan always works and the temperature is high... in Windows I had not this problem.

You can see the governing mode like so:

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
