When starting NVidia X server settings(yes,its working) says that GT630M is working, all is good(but recently terminal show that GT630M is not using by system) and!!! it has a temperature about 56!!! degreese(celsium)!How its possible?I dont understand. Bamblebee configurator gui is not working, and gives an errors after trying start.
Please help me. My notebook is so hot, that i cant put my hand on it a long time!
P.S. Sorry for my terrible english.
