Hi,
I progressed a little bit on that stuff today.

I've found two acpi messages in my DSDT which i believe are linked to switch
the Optimus mode on, and control the ION status.
See an extract of my DSDT here : http://pastebin.com/cSyADcpf
I've tried the 3 signals of DGPU in testoff.sh and they're working, then i
tried to modify the asus1215n.sh with those signals, but i think i didn't
make it well… in fact i don't know what i'm doing exactly.
Now, i don't know what to do next, i'd like to have some advices of people
who are more experimented with that stuff because i'm quite a newbie in ACPI
control…

cordially,
Quentin Gibeaux.

ps: i've attached my dsdt and my tweaked asus1015pn.sh.
