Hi All,

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.
