Installing ATI and NVIDIA in same machine, how?

I have tryed esterday CUDA (GTX260) and ATI Stream (HD 4850) on the same PC.

Unfortunatly it is not working. 😞

Only one of them are working, and it depends which one is the first one.

It is strange, Win7 in this case support 4 displays, but Catalyst not able to finde HD4850 on the second place.

Mabe i have to connect them trough CrossFire cable.


I do not know, but now it is not working. 😞

Same result if ATI GPU is used with onboard GPU enabled.

one of dx11's feature is Heterogeneous graphics support - This was missing in Vista but was in XP. Basically you can take two different graphics cards with totally different drivers and have them run at once. But this isn't an alternative to SLI or Crossfire. Meaning if you run a game, it'll still run on one card or the other. The same thing will happen for stream computing.

Confirmed, ATI Card is not recognized if onboard graphic is enabled (that sucks!), if onboard is disabled, Linux will hang if no monitor is attached (that also sucks, because it is a compute node in the server room without kvm)

Installing ATI and NVIDIA in same machine, how?

It is possible under Linux, at least, but the drivers need to be installed in a particular order. The following worked for me using 1.3 (not tried with 1.4 or 2.0beta)

1) fully remove any NV driver from the system

2)  Install ATI drivers

3) Configure the X server to use the ATI driver

4) Install Nvidia drivers, telling the installer to neither replace the GL libraries nor reconfigure X.

CUDA can be used without any display, ATI seemed to require an  X-server to be running.

YMMV, etc.
