** Description changed: After fresh install of 24.04 the power consumption raised about 40W being idle. Previously running Ubuntu 22.04. Analysis found that the the step from login screen to Ubuntu/gnome desktop consumes ~40W. Doing the same with KDE doesn't do that. The KDE desktop is near login screen power consumption. The Ubuntu/gnome behaves the same as the gnome/gnome package. CPU usage/load is near zero. Setting the CPU governor to powersave reduces the power consumption significantly. The default schedutil governor is a pretty bad choice. It seems that gnome shell does something that prevents the CPU from going to sleep, without creating lots of CPU load. The governor conservative produces much better power consumption. Not sure what gnome does to keep the CPU in boost mode but it waists a lot of energy. - I use a desktop PC with AMD Ryzen 5900x, using 65W eco mode in BIOS. - Connected via power meter. + I use a desktop PC with AMD Ryzen 5900x, using 65W eco mode in BIOS.
