I just thought of trying to get my hands on opencl and cuda stuff. I do have a machine with GeForce 210, I know it’s an very old card but as I said just wanted to do some testing. After installing Ubuntu 14.04 X86_64 I updated to driver 340.96 and everything was working fine. After installing cuda 7.5 (local installer) there is a problem with display. I followed several articles but nothing is helping out. I would be grateful if anybody shed some light here.
