Maybe it's possible to get it working.
I found this http://popies.net/sonypi/
Then it said,
In order to automatically load the sonypi module on use, you can put those
lines in your /etc/modprobe.conf file:
alias char-major-10-250 sonypi
options sonypi minor=250
This supposes the use of minor 250 for the sonypi device:
# mknod /dev/sonypi c 10 250
Then it said to install spicctrl, the command line utility that
could adjust the brightness level, etc.
After that, I ran spicctrl which gave me these options.
Sony Vaio SPIC control program version 1.9, Jun 28, 2005
Usage: spicctrl [COMMAND] [OPTION]...
-a, --getacstatus get AC adaptor status
-b, --setbrightness=NUM set lcd screen brightness (0-255)
-B, --getbrightness get lcd screen brightness
-c, --getbat1capacity get first battery capacity
-C, --getbat2capacity get second battery capacity
-l, --setbluetoothpower=NUM set bluetooth device power state (0-1)
-L, --getbluetoothpower get bluetooth device power state
-p, --powerstatus print out battery summary
-r, --getbat1remaining get first battery remaining capacity
-R, --getbat2remaining get second battery remaining capacity
-s, --getbat1status get first battery status
-S, --getbat2status get second battery status
-f, --setfanspeed=NUM set fan speed (0-255)
-F, --getfanspeed get fan speed
-T, --gettemperature get temperature
I ran then
and it gives me this.
# spicctrl -B
/dev/sonypi: No such file or directory
How can I fix that? I thought sonypi was installed because it came as default
with the kernel since the 2.4.7 kernel. If you guys or gals! could help me
on how to get the /dev/sonypi it would be great because this looks like
my only chance at being about to control the brightness.
