Hi to all, I have some good news about vga_switcheroo and 1215n. I try to make a summary of my test.
I use the 2.6.38 kernel from kernel.org. I boot linux in runlevel 3 and by default my kernel loades module i915 for intel integrated graphic card. Then when I load the module nouveau via modprobe in /var/log/messages file I see cleary that vga_switcheroo is enabled.. I connect HDMI port to a tv.. At this point I try to switch video cards and it happens that a netbook's flat panel become gray color as the console goes on tv, so I conclude that the nvidia card is actually working. At this point I start the graphical session with the command: init 5 and X server doesn't start automatically because it needs nvidia configuration in xorg.conf. So I make a basic configuration and the login screen is prompted to me on the tv, via hdmi. At this point, however, I need your help to better understand how to use flat panel of netbook with the disceret graphic card. In fact, if I do the test without connecting the HDMI cable I get nothing on flat panel ofnetbooks. Any suggestions?
