I was just trying to run Voxatron on my notebook with optimus, but it simply fails to start.
I have Fedora 17 and Bumblebee to run OGL stuff on the discrete card.
The notebook has a GT555M and some internal Intel Sandybridge GPU.
If I try to run Voxatron with Bumblebee(via optirun) it spews these errors:
ERROR: ld.so: object 'libdlfaker.so' from LD_PRELOAD cannot be preloaded: ignored.
ERROR: ld.so: object 'librrfaker.so' from LD_PRELOAD cannot be preloaded: ignored.
If I try to start it normally on the Intel GPU it neither starts nor prints any errors.
