Have you tried adjusting via powertop --auto ?
Hi Takashi I remember having one bug report related to this topic. I was showing comparison between clean ubuntu and clean tumbleweed intall with ubuntu using 3-4 times less power in idle state. I think I was not convincing enough but now it is another person with another hardware stating the same. I tried to switch from power-profiles-daemon to TLP and results are very promising. I will add them below. Still a strange thing is that ubuntu uses PPD instead of TLP anyway... Hi , I did some testing , my setup is: • XP9700 with 4k display , dual NVME • brightness set to 20% • wifi on and connected, BT on and connected to mouse • OpenSuse Tumbleweed with latest updates and 6.7.5 kernel • KDE plasma 5.27.10 on Wayland and a number of autostart apps • I did restart before each test both for PowerProfilesDaemon (PPD) and TLP. PPD : in power-saving mode using KDE was a pain I experienced 1-2 seconds gui freezes, plasma animation stutters and I can literately feel system was extremely slow , still power consumption/discharge rate was huge on performance mode I the experience was OK but with a lot of heat forcing the fan to go crazy or if I forced thermal mode to quiet my laptop would burn my hands. TLP: all works smooth, no option to change modes in KDE plasma integration on power connect/disconnect events but it seams TLP is clever enough so no manual settings are required. Measurements: See the graph where I marked PPD with yellow and TLP with green. Conclusions : I changed to PPD some time ago when I discovered Alex’s Dell-power-manager app that supported it well, then I discovered PPD had nice integration with KDE plasma that allowed me (in gui) to set profile changes to power-saving when AC was disconnected. Now after comparing the data and the experiences I am reverting back to TLP and I recommend the same.
