uninstalls the kernel package

I would not recommend someone who does not know what they are doing replacing the DE, the process heavily varies depending on your current setup. If you want Ubuntu with KDE, just use Kubuntu.

SteamVR runs terribly on Linux, Monado/WiVRn is pretty playable.

I prefer to drag my friends toward games without integrated rootkits. Better for them, better for me. Thankfully, there are plenty of games to choose from today.

If something does not work, mostly it either has a kernel level anticheat or it’s Adobe. I just learned to live without these, I think it’s for the best. You can even do VR on Linux nowadays!

I’d say your best chance is just launching an Android version with a controller (I assume Android version supports controllers). It’s just that nobody on PC plays Bedrock. All the community content (mods, resource packs, custom tools) is for the original version, after all, and Bedrock is a walled garden.
