Tripple monitoring with ubuntu? 2 different vga cards

[Megabug]

Hi,

I am planning to switch on my main computer from a well knows and hated OS to ubuntu.

My problem is, that I am using 3 monitors on that PC. In the middle is a 24" TFT and on both sides of it I have 17" TFTs.

The 24" one is running at the onboard Nvidia 7050PV chipset @ DVI and the both 17"s are running at a Radeon X550 on PCIe x16.


Oh yes, and the resolutions are:
24" -> 1920x1200
17" -> 1280x1024


So, how can I make things work? As far as I see this, the problem are the different resolutions and/or the different grphic cards?


Thanks in advance...

Oh yes, and if not Xinerama, what else? randr won't work (shows only one screen, connected to my primary card)
