Recently I am trying to install Nvidia's Cuda framework, which requires the Nvidia's graphic card. I have tried several solutions described in many posts, like: http://askubuntu.com/questions/519372/ubuntu-and-asus-g750jm-gtx860m-nvidia-problems, http://askubuntu.com/questions/162639/how-do-i-get-ubuntu-to-recognize-my-nvidia-graphics-card, http://askubuntu.com/questions/523528/why-does-ubuntu-14-04-not-recognize-nvidia-geforce-310m-hardware, and several else. Unfortunately none of them works for me. My problem here is even trickier than most of the posts, because my system can't recognize the model of my graphic card: >jinchao@jinchao-laptop:~$ sudo lshw -C display [sudo] password for jinchao: *-display description: 3D controller product: NVIDIA Corporation vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a2 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:51 memory:d0000000-d0ffffff memory:a0000000-afffffff memory:b0000000-b1ffffff ioport:4000(size=128) memory:b2000000-b207ffff *-display description: VGA compatible controller product: 4th Gen Core Processor Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 06 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:47 memory:d1000000-d13fffff memory:c0000000-cfffffff ioport:5000(size=64) My laptop is Lenovo Y50 and it has a Nvidia GTX960M graphic card.
