[Bug 700646] Re: nVIDIA 425M (with Optimus) is not detected

 

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?

kern.log says (anyway if enabled or not):
