I have a strange issue with the Keyboard. Generally Volume buttons should work with Fn + F11 or F12 and Mute FN + Mute key. But it seems that Fn doesn't work or is not required. When i press F11 or F12 is changing the volume (without Fn) (Same goes for brightness) instead of showing Desktop or Dashboard. The mute key just display Mute (OSD) but does not actually mute the sound.
Did i missed something? I remember that with Chameleon the Fn + F1 - F12 was working. Is it because of UEFI implementation of Dell?
Well i started with custom settings from Clover (Inject Nvidia, also NvOptTbl). This is how i managed to enable it. Now i am trying some cuda tests. I don't care so much about 3D as much for CUDA. (Premiere CC, DaVinci ...)
