I have installed Lubuntu 22.04. on an old HP 15-db0021ng notebook.
Everything runs OK, but the CPU frequency appears very high, even when idle. It never drops below Freq: 56% and frequently scales to 116% while browsing Instagram or watching YouTube videos.
I installed cpupower-gui. By default the governor is schedutil. When I set it to powersave, the CPU frequency remains at 56% and overall performance gets slower.
For some reason, when I run the command:
cd /sys/devices/system/cpu/cpu0/cpufreq && paste <(ls *) <(cat *)
some lines get shifted, please see below.
Is there an error somewhere that I can possibly fix?
Many thanks in advance!
