[Trisquel-users] Re : CPU frequency stuck at minimum speed

[lcerf]

The same problem apparently occurs whatever the version of the kernel:  
besides version 4.15, I tried versions 4.4 (Trisquel 8's default) and 5.4  
(from jxself's APT Repository for Linux-libre).  I am on AC-power and the  
battery is plugged.  There is no file  
/sys/devices/system/cpu/cpu*/cpufreq/bios_limit.  I have written 1 in  
/sys/module/processor/parameters/ignore_ppc: no effect.  100 in  
/sys/devices/system/cpu/intel_pstate/min_perf_pct: no effect either.   
According to lm-sensors, the temperature of the cores, about 50°C, is not  
high, defined as 80°C.

I am running out of ideas...
