I've obtained a copy of the .deb for the Steam beta, but it was pretty disappointing to see that it simply doesn't run.

Hardware - Dell XPS L502, with Nvidia Optimus

I have bumblebee installed. Trying to run Steam with the Intel HD 3000 completely fails to start it.

• Message received

  Installing breakpad exception handler for appid(steam)/version(1352224866_client)

followed by a crash with no other information provided.

Trying to optirun steam runs the client, but as soon as it gets to the home screen, it says that the Nvidia drivers I am using are out of date (and Steam requires newer drivers to run). It's probably worth to note that it throws the same Installing breakpad... error when run with optirun, but it doesn't crash the client immediately.

Any way to fix this? Also, is there a way of manually updating the drivers in bumblebee without breaking anything? Alternatively, is there a reliable way of completely disabling the Intel GPU (in order to use the Nvidia GPU exclusively)?

Note: I am using Xmonad with gnome-fallback, if that makes a difference. However, when I tried everything mentioned with Unity (2d), everything was the same, so I guess it has nothing to do with the window manager in use.
