I tried to switch from i3 a few months ago and spent several hours trying to get it to work with my Nvidia card before finding out that the project doesn't support Nvidia for ideological reasons.

I'm not well versed in the details of the conflict, and of course any open source project is not compelled to support anything they don't want to. That being said it would have been nice to know that they have no plans to support a large percentage (majority?) of the consumer, dedicated GPU market.

If/when I am able to get a new AMD card I will certainly try it then.
