CUDA on Alienware M11xR2(optimus) Can't install developer driver

[planetmarshall]

I have an alienware M11x R2 and I am having a bad time trying do install cuda and made it work, i.e. compile and have the executable files to recognize the NVIDIA device. How did you manage to have cuda working?

Thanks for any light.

[list=1]

[*] Install the 260.19 developer drivers. Opt not to modify your X config ( this will not work as the driver does not support using the NVIDIA card as a display device )

[*] Install the nvidia module with modprobe ( may or may not be necessary ).

[*] Install the CUDA Toolkit. Modify your startup file (.bashrc or whatever) to add the location of the cuda libraries to LD_LIBRARY_PATH

[*] Install the SDK

[*] Compile the cuda utils and deviceQuery sample in the SDK. If this doesn’t work you’ve done something wrong.

[*] run deviceQuery as root.
