インストールはしても、デフォルトでは特に助けにはならないっぽい。
仮想マシンを動かしていると、90度を超えたりする。

/etc/cpufreqd.confを少しいじってみた。

[Profile]
name=Performance High
minfreq=100%
maxfreq=100%
policy=performance
[/Profile]
[Profile]
name=Powersave Low
minfreq=40%
maxfreq=40%
policy=powersave
[/Profile]
 
[Rule]
name=AC Rule
ac=on
profile=Powersave Low # デフォルトは"Performance High"
[/Rule]

で、sudo systemctl restart cpufreqd.service。
少し鈍くなった気がするが、さしあたり、先程の警告は出なくなった。

チュートリアルからは時々はみ出さないと、応用力にはなるまい。

なんか転送元が変なようだが、ともかく入るべきものは 入った。起動もできた。
