Hello,
I’m trying to setup Cuda on my Gentoo.
I’ve successfully installed the driver (177.73), the toolbox (in /usr/local/cuda) and the sdk,
but the examples are failing (it runs but the display is broken or Test FAILED appears).
I’ve been using the rhel *.run files (from the NVIDIA website).
Here is the device query output:
There is 1 device supporting CUDA
Device 0: "GeForce 8400M GT"
Major revision number: 1
Minor revision number: 1
Total amount of global memory: 66781184 bytes

Maximum memory pitch: 262144 bytes
Texture alignment: 256 bytes
Clock rate: 0.90 GHz
Concurrent copy and execution: Yes
Test PASSED
Press ENTER to exit...
My graphic card is a Geforce 8400M GT 256 Mb (memory is correctly detected).
All the examples have been run with both version 177.73 and 177.80. I’ve also tested running them as root
but it did not change anything.
For instance, in the image denoising example, the windows appears, the noised image is displayed but pressing 1,2,3,4 doesn’t change anything (but there is console output saying that
the mode has been switched).
Any idea about how to solve that issue? I’ve seen other people having the same kind of problems but I didn’t catch any answer that could help me to solve the problem.
(I’m attaching a nvidia bug report to this topic).
Thanks!
