Definitely it's almost impossible to achieve that but I will some things as well... The Nouveau driver is a monodrome I suppose. I was googling and found that maybe I can start a new X session at the second VGA but I will keep searching for now.

EDIT: That's the final setup that works (only for basic stuff). Only with the Nouveau driver activated. I don't think even a video with VLC will play correctly. It messes up a bit at the eight one which I thought it will be a black area because there is no screen there. The resolution I get is 1152x864 but the native one of my screen is 1600x1200. I can't use the full resolution because if I try to switch to it, the PC freezes. So I will stay as is. That's the best I can do for now.

Sounds like a nightmarish configuration, only the brave would attempt this. Personally I would never mix and match vendor graphics. Good luck :)

I create this thread to ask if there is possibility for a triple screen setup with Linux Lite.

I bought recently a PCI graphics card, ATI Radeon 9200, to accompany my NVIDIA GeForce 210 which is placed at a PCIe x16 slot. The PCI card was tested alone to see if it works properly, which it does but when I place both of them onboard, I can't use them both. I searched and found that is viable but a bit tricky to setup. The main problem is the proprietary drivers that may conflict with each other.

By the way, all this testing caused the bug at the login screen when using Linux Lite 1.0.8. (I didn't installed any driver for the ATI card. It worked with a generic one.)

The last I tried was to change from what VGA the PC will boot. PCI or PEG (PCIe). When I choose PEG only the NVIDIA seems to work all the way. When I choose PCI, it boots with PCI, at some point all the screens work (not just connected, the light at the respective buttons indicates that they show something) even those at the NVIDIA adapter but before the login screen show up the monitor that is connected to the ATI card (PCI) "goes to sleep".

I didn't tried to install a proprietary driver but I don't think that's the case because when I'm going to see the monitors setup at the Settings > Display, appear only 2, those of the NVIDIA adapter.

At the moment I connected it on the motherboard and booted with the PEG setting, but all screens worked only on boot procedure. When login screen appears, the monitor attached to ATI stops showing something and "goes to sleep" once again.

Any idea appreciated. Thanks in advance.

**EDIT**: After some testing I realised that the proprietary driver is the cause of not detecting the 3rd monitor. I switched to Nouveau driver to get all of them to work. But when trying to configure them from the "Display" most of the times the PC freezes or the 3rd monitor (attached to ATI) get messed up (the screen goes crazy :P ).
