envycontrol VS ALVR

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.

They also achieve very low latency, I didn't follow every single optimization they added but it basically boils down to a few encoding tricks (better image in the center, accept blurriness in the peripheral vision), good network infrastructure, and hardware decoding / encoding being really fast.

To use steamvr on flatpak I used this tutorial . There was a disclaimer that nvidia GPUs are not supported, but the guy that suggested it has a 3090, so it might work for me too.

They have a Wiki page on GitHub with a settings tutorial and troubleshooting. A downside with a lot of open-source software is that it's relatively difficult to setup but it might fix some of your issues.

You can play wirelessly using Air Link, Virtual Desktop, or ALVR.

They also have a detailed wiki page on GitHub

Quest 2 needs some workarounds (dev mode account), but once you've done those you can just install ALVR (I recommend nightly). As for the games, check ProtonDB. Some VR games (Pavlov beta, for example) have EAC that blocks proton. Some VR games don't work with ALVR due to https://github.com/alvr-org/ALVR/issues/1392, like the Pavlov beta and Crawlspace. Just install the proprietary NVIDIA drivers and use Xorg and most things should work fine. Steam has Proton, which lets you play Windows games with high performance.
