sgjava Posted May 30, 2018 Share Posted May 30, 2018 Running latest Ubuntu 18.04 for NanoPi Duo with updates as of last night and CPU governor stays at ondemand even though I set it to conservative in /etc/default/cpufrequtils and reboot. CPU frequency settings do take effect, just not the governor. Link to comment Share on other sites More sharing options...
tkaiser Posted May 30, 2018 Share Posted May 30, 2018 With Xenial it was this way: https://github.com/armbian/build/issues/499 -- so I would assume with Bionic they do it now differently and we have to mask another service? Link to comment Share on other sites More sharing options...
sgjava Posted May 30, 2018 Author Share Posted May 30, 2018 OK, I'll check for a init.d or systemd conf tonight when I get home and see if I can figure it out. I'll report back here. Link to comment Share on other sites More sharing options...
