I'm running LMDE on ASUS G53SW-XR1 Core i7-2630QM/8GB/640GB/NVIDIA GeForce GTX 460M (2.1 compute capability). I'm using the nvidia driver from repositories, 2.6.32-5 kernel, and after some dabbing managed to get almost all the important fn-keys to work with it (LCD brightness, wifi on/off, suspend, screen on/off, screen cloning). If interested I can post steps that I used to get the screen brightness and hibernate running. However I still don't have the keyboard backlight and most importantly, the volume keys. Does anyone have experience getting those to run on this or similar (G73) laptop?
