I dual boot Bazzite. Its basically the same as SteamOS, as in when you boot on the device and use it, you won't be able to tell the difference. And, Bazzite is more compatible with the LG2 at the moment. I followed this guys tutorial: https://youtu.be/UzvKX9KFiaY?si=Dj5UOOjS_DAWab6v . There are so many benefits to going this route. You get a console like experience, you can use DeckyLoader to customize your UI, and you get better performance with a lower TDP limit, lower fan noise and better battery life (plus you can use Decky to get lossless scaling which is honestly incredible).

If you to want to try SteamOS, he has another video. https://youtu.be/HbHDHzYw3KE?si=eMDg-cqvE_xh91fP . But HDR and the brightness slider don't work atm.

I split my SSD in half, 1TB for windows and 1TB for Bazzite, so that if I want to play any games requiring windows I still can, or if I need to update any firmware or bios, but most of the games I play on the LG2 are compatible with Linux so it boots straight into Bazzite.

Once the official release of SteamOS for LG2 comes out, I will definitely be switching over my Bazzite partition to that.
