Chip GT520M does not work

1 Attachment(s)

Hello:

My laptop, Lenovo z470 has two video cards:

- Nvidia GT520M
- Intel HD 3000

In openSUSE 11.4 (x86_64), when I see the System Information, the O.S recognize both cards BUT only works the Intel.

- If I install the driver (NVIDIA-Linux-x86_64-280.13.run) the "X" don't work.
- If I edit the xorg.conf to force to use the Nvidia card, the "X" don't work.
- If I edit the xorg.conf to force to use the Intel card, the "X" works.

Nvidia do not support optimus on Linux.

I do not think you can turn off the switchable graphics. IGP is connected to the display and the NV GPU works through routing.

You need Bumblebee to use the card.
