I am trying to run Steam on my Fedora 21 system with NVIDIA Geforce GTX 860M graphics card.

This is what I get (same result with primusrun and optirun)

$ optirun steam
Running Steam on fedora 21 64-bit
STEAM_RUNTIME is enabled automatically
/home/mukundan/.local/share/Steam/steam.sh: line 730: 31159 Segmentation fault      (core dumped) $STEAM_DEBUGGER "$STEAMROOT/$STEAMEXEPATH" "$@"

Bumblebee is working fine since I am able to use it for other applications. For example,

$ primusrun glxspheres64
Polygons in scene: 62464
Visual ID of window: 0x20
Context is Direct
OpenGL Renderer: GeForce GTX 860M/PCIe/SSE2
61.297444 frames/sec - 68.407947 Mpixels/sec
60.007811 frames/sec - 66.968717 Mpixels/sec

I am running NVIDIA 340.46 drivers. How can I get steam to work?

Thanks!
