My nVidia GPU (GTX650-DC) can't be detected by my computer(OS is Ubuntu 14.04). I've searched for related discussion([Ubuntu 14.04 couldn't detect nvidia graphic card (not even detect the model of card)](https://askubuntu.com/questions/652721/ubuntu-14-04-couldnt-detect-nvidia-graphic-card-not-even-detect-the-model-of-c)) where the nvidia GPU information can be obtained by the command "sudo lshw -C display." However, the information shown on my computer is as follows and it seems that my nvidia GPU is never detected. Have anyone run into this situation as well? Any suggestions would be highly appreciated!

Output of `lshw -C display *-display` :

```
:~$ sudo lshw -C display   *-display
