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: [ 2.769730] nouveau 0000:04:00.0: enabling device (0004 -> 0007) [ 2.769936] [drm] hdmi device not found 4 0 1 [ 2.770067] nouveau E[ DEVICE][0000:04:00.0] unknown chipset, 0x108100a1 [ 2.770069] nouveau E[ DRM] failed to create 0x80000080, -22 [ 2.770697] nouveau: probe of 0000:04:00.0 failed with error -22 [ 0.000000] DMI: LENOVO 20ARS0XL00/20ARS0XL00, BIOS GJET67WW (2.17 ) 12/10/2013 % xrandr --listproviders Providers: number : 1 Provider 0: id: 0x49 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 6 associated providers: 0 name:Intel The issue also seemed to appear at https://github.com/Bumblebee-Project/bbswitch/issues/78 I attached the full dmesg and hope you can help!

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.
