I'm running nvidia graphics cards (2 connected to monitors) so its a royal pain but I'm running the nvidia drivers. Its not that easy to set up the first time (I spent a lot of time the first time) but now its a painful process but its quite doable.
Sounds like your doing multi-card, not specifically multi-monitor, am I mistaken?
2 cards and 4 monitors 1 monitor in portrait and 3 in landscape mode (wouldn't mind a 4th in landscape!)
Xrandr works great for multi-monitor, but does indeed assume single card. The assumption is not Xrandr's fault, support for multi-card been a target feature of Xorg to for the last decade. Multi-monitor single cards have been "good enough" for just as long.
My research showed that multi-card has been a 'hope' for a very long time. It must be because few people actually run more than 1 graphics card. I wish there were an easy way to slave cards together (I actually have 3 graphics cards - - - wanted them for serious numeric processing).
You need to remove the nouveau driver. Means that first you need to get
your system running on something else and then you black list nouveau and then you install the nvidia drivers and then you need to setup all the goodies and then you can turf the nouveau drivers and then you have OK performance.
Fought with this today actually. Add to your kernel boot line:
modprobe.blacklist=nouveau
This gets it gone before it's used to by the console.
One needs to NOT be running any x window stuff at that time too! The whole process isn't very straightforward. Its a pity that nouveau weren't just either seriously upgraded or perhaps deprecated. Dee
