GPU3 is "configured"

[Predrag Punosevac]

Dear Autonians,

GPU3 is "configured". Namely you can log into it and all packages are
installed. However I couldn't get NVIDIA provided CUDA driver to
recognize GPU cards. They appear to be properly installed from the
hardware point of view and you can list them with

lshw -class display

However what scares the hell out of me is that I don't see NVIDIA driver
loaded

lsmod|grep nvidia

and the device nodes /dev/nvidia are not created. I am guessing I just
missed some trivial step during the CUDA installation which is very
involving. I am unfortunately too tired to debug this tonight.
