envycontrol VS ryzen-controller

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.

Also, you can use the Ryzen Controller software to completely limit the temperature of the CPU. It lowers the performance of the CPU but also lowers the power consumption. Because there is dedicated graphics, for just general tasks like web browsing you can even limit it to 50 degrees and it will not go above that no matter what you do. It makes the PC slower for more intensive tasks so of course you'd want to raise the temperature limit setting when you want to do heavier work. The nice thing is that this method does not create additional noise, it simply lowers the performance of the CPU.

here you go my friend

/u/Number-1Dad circling back, and I'll be damned. After a bit of finnagling, Ryzen Controller is woring rather interestingly. The TDP limiter stops the whole thing short of takeoff.

Ryzen controller got your back. Newest version might not work with your CPU, old one will. The trick here is to limit your iGPU clocks to the lowest possible for everyday usage and let your system decide in gaming. You can also set throttle temp for processor to avoid throttling.

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