Hi list,

Furthermore, if the laptop has two graphics cards, one intel and one nvidia, which I understand is called Optimus™ by Nvidia, there seems to be the bumblebee project to use this under Linux (with one free implementation in bumblebee and one non-free in bumblebee-nvidia packages). This package also provides the optirun binary which apparently can be used to start specific programs with one of the two cards explicitely?
Try building Gem with/without optirun on your machine and check the config status.
In the first build directory, do ./configure make
In a 2nd directory, do optirun ./configure optirun make
You should see differences in the config.log and check for differences in libraries linked
