Hi archers, I've been runing AL for some time, and, after more games has been added to steam lib, play them. So I've moved to bumlebee setup, in order to exploit my beefy GFX 660. Well, that's what I've got: szymon@arch /etc/X11/xorg.conf.d % optirun -vv glxgears [ 2103.749413] [DEBUG]Reading file: /etc/bumblebee/bumblebee.conf [ 2103.750131] [DEBUG]optirun version 3.1 starting...

Cheese, Pizza & Tacos Szymon Szydełko PS. I haven't any video "Driver" clauses in xorg.conf.d - there are only evdev and synaptics references. PPS. I use nvidia-bumblebee-ck driver and corresponding kernel, but on arch' mainline, everything is the same.
