envycontrol VS cpupower-gui

You're probably looking for envycontrol ... it will allow you to switch back and forth between integrated/hybrid/dedicated-only graphics as needed. I used this on my 2023 Legion Slim 5 and it made a huge difference in power consumption. Now I only enable dedicated if I need it for something specific, which is rare for me. Computer generally sips between 16w-20w doing basic browsing tasks, with no other optimizations performed (this is on Fedora Silverblue)

Install EnvyControl, which is a useful package that can offload applications to the integrated GPU and turn off the dedicated Nvidia GPU. This will add a few hours at least to your battery life. Distro-specific instructions: https://github.com/bayasdev/envycontrol

Check out this video. https://youtu.be/Pn2iUgW3l6w . It's how I setup my graphics card. You could also use envy control https://github.com/bayasdev/envycontrol.

Now, it's much easier to enable the Fusion repository and Envycontrol makes it as easy as Ubuntu to switch GPUs! I also use DisplayLink for additional monitors and there is now a 3rd party rpm for that.

use envycontrol

I thus played a bit with https://github.com/bayasdev/envycontrol which is listed on the archwiiki, the problem is that now, even when selecting the "nvidia" mode and even when going back to "discret graphics" in the bios I'm encountering bugs I didn't have before, mainly SDDM being really zoomed, i3 borders being HUGE (while the rest is normal, I didn't change my config so it's likely not a DPI problem there), glitches when I first login with polybar duplicating itself and the wallpaper being broken, requiring to refresh i3 to have those 2 things fixes, picom animations are also super glitchy.

I use cpupower-gui for this, and installing the .deb on their releases page works flawlessly. In my experience, it does a pretty good job at improving battery life, even on modern systems.

I was looking into using envycontrol to disable the dGPU in linux, and maybe ryzen controller or cpu-power to limit cpu power usage.

For power management, you could use something like cpupower-gui to underclock the CPU whenever you need to conserve battery.

There's https://github.com/vagnum08/cpupower-gui but its GTK based

I use gnome so I have no clue what the KDE slider does, sorry! But you should check out cpupower-gui

You can also use cpupower-gui to park cores, although Phawx mentioned he used some other tool. In this tool, you just need to uncheck the cpu you need to turn off.

Also I would recommend using cpupower-gui if your frequencies are too high. This tool lets you do frequency scaling and lets you select a governor in a gui.
