I do have the same combination (i5 + 425M), but on Ubuntu 11.04. The nVidia-Card is detected and I had the driver installed but "not in use". Rebooting failed so I disabled the card through failsafeX. I tried it with vgaswitcheroo but I don't get it to work out... It's running stable since, but without the extra GPU - any ideas?
