Bumblebee " Failed to initiate mode change "

Hi! I already had success getting nvidia optimus running on my older laptop.

When I run

$ optirun glxheads

Bumblebee outputs the following:

[31653.201204] [INFO]bumblebeed 3.2.1 started
[31682.890210] [WARN][XORG] (WW) `fonts.dir' not found (or not valid) in "/usr/share/fonts/OTF/".

[31682.890325] [ERROR][XORG] (EE) NVIDIA(0): Failed to complete mode change

It's the two last lines that worry me. glxheads gets the right information about the card as it outputs 

Name: :0
  Display:     0x19e8d90
  Window:      0x2800002
  Context:     0x1a16860
  GL_VERSION:  4.4.0 NVIDIA 337.19
  GL_VENDOR:   NVIDIA Corporation
  GL_RENDERER: GeForce GT 755M/PCIe/SSE2

But steam doesn't . All steam sees is the intel integrated card when I start it with optirun or primusrun.

3.14.4-1-ARCH

Thanks a lot!
