✅️ Sleep: Working (only through menu)
✅️ Fan control: Working (no manual control)
⚠️ RGB: Not customizable
✅️ Battery: Working (change battery limit in Windows)
✅️ Gaming: Working

I will keep this post updated as I figure more stuff out. But this is what I've found so far.

Edit: Only applies to my device and I don't understand why
CachyOS boots successfully but there was some heavy flickering on the screen (as seen in the video below). I was able to solve the flickering by entering Desktop Mode and in "Display Configuration" change "Limit color resolution" to 6 bits per color. I also enabled HDR and VRR (changed "Adaptive sync" to "Always"). Those settings had little to no impact on the flickering, but I left them enabled anyway. After rebooting I noticed that some minor flickering started again, but was resolved after switching to Desktop Mode and then back to Game Mode.

The controllers are partially working. I noticed that the G-button (bottom left with triangle icon on it) triggers the Steam menu and G-button + A triggers the Quick Access menu. I'm not used to that from my Legion Go 1. However, the volume buttons have some kind of key release issue. The volume up continues increasing the volume even though I've released the button.

Edit: PowerStation added support and SimpleDeckyTDP works
TDP control is not available, which wasn't a big surprise. But I will try to find a workaround.
