Hi,

I'm using linux 3.12.9 on a Thinkpad T440s with Intel HD 4400 and Nvidia GT
730M. The nvidia card is not working with nouveau:

Hi Tobias

Initial mode-setting support for nv108 has been added in 3.13, with pgraph
(read opengl) landing in 3.14. Give those a try but note that gl support may
not be a smooth experience as expected.

3.13+ should provide modesetting, 3.14-rc1+ should provide the pgraph fw
required to do 2d and 3d acceleration. The mesa driver is known to be very
buggy for it (and I've yet to hear someone actually confirm that it uses the
gk110 shader isa... if it uses the 'regular' nvc0 isa, then after a
couple of
small fixes, mesa will be much less buggy).

You probably don't need to use bbswitch if you have runtime pm enabled; the
card should get automatically powered down by the driver.

This particular issue should not happen on recent kernels (3.13+). Feel free to
reopen if it does, or open a new issue if there are other problems.
