Default GT540m and 270.41.06

Hi all,
I have an Asus Notebook (K53SV) with Nvidia GT540m.

As I can see, the latest driver (v. 270.41.06) seems to support the GT540m. Btw, I have just installed Ubuntu 11.04, which has this driver version in its repository, but it doesn't work (black screen)...

I know Nvidia doesn't support optimus, but I'm asking myself if there is a way to use the NVIDIA graphic card only (without the Intel one), installing these driver...
Also because GT540m is with Optimus only... so if this driver is for GT540m it should work in some way :-/

Has someone tried this driver with GT540m? Thank you

If it's Optimus, there's no way use the nvidia card.

Mmm..but IF:

- GT540m has optimus
- the 270.41.06 driver says to support GT540m
- it's impossible to use the Nvidia card if it's optimus (as you said)

then:
In which situation should we able to use the 270.41.06 driver with GT540m?! Is there a notebook with the GT540m, but without integrated graphic? should it work in these (now almost rare) situation ?

Thanks

It will work in laptops that have the integrated GPU deactivated, or that have a hardware mux to switch between graphic cards.

Those are one and the same. The only machines that can disable the Intel onboard are the ones that have the additional mux.

gianvito: Optimus doesn't work how you think. For all intents and purposes you only have an Intel card. Don't try and install drivers the the nVidia card. To use the nVidia card on Linux you need to use something like Bumblebee (google optimus bumblebee) which lets you use the nVidia card on-demand (same as Windows).

Basically the way Optimus works is the nVidia card sits behind the Intel card and is used in addition and only when called specifically.

No they're not. There are laptops where you absolutely cannot use the integrated graphics, it is disabled for good (they're rare and are usually expensive high-end models). Then there are laptops with a hardware mux allowing you to switch between integrated and dedicated. Then there are laptops without the mux - here the integrated graphics is always on and the dedicated one activates on-demand, either automatically (Windows) or manually (Linux with Bumblebee). These are three separate hardware designs.

I actually misread your original comment as meaning that they have disabled it in the BIOS, not permanently disabled.
