Disabling the card aslo disables the touchpad!

[falbarelli]

Hello, thanks for the work you've done with bumblebee and bbswitch.
I've got an ASUS NS53sv with a NVIDIA® GeForce® GT 540M. I run Ubuntu 11.10 64bit with kernel 3.0.0-15-generic., my versoin of Xorg is 1:7.6+7ubuntu7 and i have no nvidia driver installed (I just use bbswitch to turn-off the card, I don't need optirun).
I installed the module with DKMS and then i manually run the command sudo tee /proc/acpi/bbswitch <<<OFF. For the first time under linux the led which shows if the nvdia card is on is working, and that's really great!
But I have a really strange problem, as soons as i run the command my touchpad stops working (but a usb connected mouse works fine).
I can't explain this behaviour, could you help me maybe?

If it can help this is the output of dmesg | grep -C 10 bbswitch:

Thanks again for your great work!

[Lekensteyn]

Please generate a proper bug report according to the README. Try unloading the asus_wmi module and try again.

[falbarelli]

Ok I was going to generate a proper bug report, but I updated to the latest version (0.3) and now the problem is solved!

[ArchangeGabriel]

Then that wasn't bbswitch, because I can't believe that the only change made solved that.
