I have an Intel HD 3000 (integrated graphic card) and a nVidia GeForce 520m. I had some problems installing BackTrack and Ubuntu and I discovered thatif I set the video card from "Switchable" to "Integrated" from CMOS Utility Setup, the installation goes on and it's not freezing. I'm just wondering why... Does Linux work just with one video card or are there any commands or another ways for fixing this problem?
