Guess this means my main problem is solved, so I'm marking the thread as such. I'm now going to fiddle with my two graphic cards to get my second (and eventually, third) screen running. Apparently nvidia screws with those, too.
I got nouveau to work on the main screen by reinstalling xorg-server and mesa. Oh, and here's the relevant parts of my nf: Please excuse me if anything in this topic has an obvious fix, I kind of spent the entire night with this so I'm not really at the height of my mental capacities right now. I managed to get to slim once or twice, but my computer will then hang and become unresponsive, even for ssh. For some stupid reason nvidia insists on installing its own libgl contained in nvidia-utils which prevents me from installing any other package that depends on libgl without removing nvidia first.
I'd like to get rid of nvidia, and also need libgl so I can install the ati drivers, since I'm trying to get a second graphic card to work. I wonder if there is anyone who had/has similar problems. I've arrived at the conclusion that something is wrong with the EDID of the screen, but I can't for the life of me figure out a solution. With the nvidia drivers, I can fix this by passing the kernel nomodeset, but that's not an option with nouveau since I need KMS. I get a "Input not supported" from my Acer x223w monitor.
