What I meant about the 2 (now 3) days is that they removed the needed files from the repos on Thursday, and I finally decide to try to install it on Saturday
The other guide I found uses different repos, so I am hoping the files will still be there.
It only works on 2 monitors, though, so I will have to find something I can have the 3rd one doing. And the cube thing is more like a rectangular prism, but I guess thats the price you pay
