Hi all, I've been mostly happy with my natty install on vpcz1390x so 
far. My main remaining 'that would be nice to fix' issues are the 
graphics switch and the internal mic.

Can anyone suggest how to default to nvidia card OFF (so that I don't 
have to manually run the acpi_call module each time)

How do I do this? Currently my process was:

* get the code: git clone http:// github. com/mkottman/ acpi_call. git

* Then do this each time I boot:

cd acpi_call
make
sudo insmod acpi_call.ko
./test_off.sh


For me, .test_off.sh returns:

Trying \_SB.PCI0.P0P2.DGPU._OFF: works!

This means the discrete graphics card (NVIDIA) was turned off by this 
script. Checking my battery life, I go from 1:45 of battery time (with a 
99% charged battery) to 3:25 of battery time. Nice!

So, how do I somehow automate this, so that the NVIDIA off is the 
default setting, but still be able to easily turn it on if I ever want it?

Ideally, this would be done with the graphic hardware switch 
(speed/stamina/auto).


Thanks,

sc
