i don't now if i did things right
i simply modify the video.c file
changed 5710Z into 5715Z
saved
cp Makefile Makefile.old
nano Makefile and put this
obj-m += video.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean
then i did a make
i boot on other kernel (to be sure i can write the new module)
i copy video.ko in /lib/modules/2.6.31-4-generic/kernel/drivers/acpi/
reboot with kernel 2.6.31-4
and .... nothing changed :(
other stuff i did
cat /sys/devices/platform/acer-wmi/interface
WMID
