Linux Desplay Driver

Hi All,

Is Linux display driver is a requirement for using the device emulation mode?

Thanks Much.

No, it is not.

However, the current version of cutil is linking GL and GLUT libraries, so you need to have them installed on the system. If you are not installing the linux driver ( that includes those libraries), you need to take care of them or avoid to use cutil.

Seems I’m having trouble installing the driver. So, for now I prefer to find some way around. Do you have any suggestions?

Thanks Much.

A related newbie question:

Is Linux display driver a requirement for running SDK examples in the ‘release’ mode?

I have successfully compiled the SDK 1.1 examples in Red Hat Enterprise Linux 5, 64 bits, and have a

8800GT card installed, but without installing any Linux display driver. When I ran any of the SDK

programs such as ‘cppIntegration’, I got an error message: “There is no device supporting CUDA.”

Currently, I am using an old PCI graphics card for my display instead of the 8800GT, because I

figure that, this way, I can reserve all the resources in the 8800GT for computation.

Am I right, that is, can I use a CUDA card strictly for computation without installing any Linux display

driver?

Thanks.

No, you need to load the linux driver.

I went ahead and installed the linux driver NVIDIA-Linux-x86_64-169.09-pkg2.run and

used the automatically generated xorg.conf file. However, I was unable to start the X

server. The error message was:

(WW) NVIDIA: No matching Device section for instance (Bus ID PCI:1:0:0) f

(EE) No device detected

I am running Red Hat Enterprise Linux 5, 64 bits, with a 8800GT card installed. Could you

suggest what I should do to resolve the problem?

Thank you.

P.S. The automatically generated xorg.conf file is:

The problem is resolved: It was a bad PCI-E power supply cable. I replaced
the cable and the 8800GT card is working fine now.
