Linux on Sony Vaio - Miscellaneous
A page that I found recommends installing the
sjog packages to get control over the LCD brightness and JogDial.
spicctrl working, you need the
sonypi kernel module. Fortunately, it’s installed in the stock Debian kernel.
Unfortunately, there’s no entry in /dev for it. Create one with:
# mknod /dev/sonypi c 10 250
Create a new file,
/etc/modutils/sonypi, containing the following:
alias char-major-10-250 sonypi options sonypi minor=250
update-modules to rebuild
Then, you can test it like this:
$ spicctrl -a $ spicctrl -b 100 $ spicctrl -b 255 $ sjog
I haven’t figured out how to get the jog control to come back when you next use the dial. I’ll look into that later.
