[Solved]Problems with nouveau and Acer monitor

Ahoi,

I'm having a bit of a hard time trying to get nouveau to work. I get a "Input not supported" from my Acer x223w monitor. 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'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.

I wonder if there is anyone who had/has similar problems. 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. 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 managed to get to slim once or twice, but my computer will then hang and become unresponsive, even for ssh.

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.

Oh, and here's the relevant parts of my xorg.conf:

Section "ServerLayout"
    Identifier          "DualScreen"
    Screen          0   "Screen0"
    Screen          1   "Screen1" RightOf   "Screen0""
    Option              "Xinerama" "1"
EndSection

Section "Monitor"
    Identifier          "Monitor0"
    ModelName      "Acer X223W"
    HorizSync         31.0 - 84.0
    VertRefresh      56.0 - 77.0
    Option             "Enable" "true"
EndSection

# This monitor works flawlessly
Section "Monitor"
    Identifier          "Monitor1"
    Option              "Enable" "true"
EndSection

Section "Device"
    Identifier          "Device0"
    Driver              "nvidia"
    Screen              0
EndSection

Section "Device"
    Identifier          "Device1"
    Driver              "nvidia"
    Screen              1
EndSection

Section "Screen"
    Identifier          "Screen0"
    Device              "Device0"
    Monitor             "Monitor0"
    DefaultDepth        24
    Option              "TwinView" "0"
    SubSection "Display"
        Depth               24
        #Modes               "1680x1050_60.00"
    EndSubSection
EndSection

Section "Screen"
    Identifier          "Screen1"
    Device              "Device1"
    Monitor             "Monitor1"
    DefaultDepth        24
    Option              "TwinView" "0"
    SubSection "Display"
        Depth               24
        Modes               "1080x1024_75.00"
    EndSubSection
EndSection

Update:

I got nouveau to work on the main screen by reinstalling xorg-server and mesa. Apparently nvidia screws with those, too. Oh boy. I'm now going to fiddle with my two graphic cards to get my second (and eventually, third) screen running. Guess this means my main problem is solved, so I'm marking the thread as such. Hooray for posting on a forum, then finding the fix yourself immediately afterwards.
