sony-laptop on AR series

[eaglex]

Hello,

I own a Sony Vaio VGN-AR41E and have gotten the Fn keys
to report ACPI events by adding:

---------- paste ---------
            .ident = "Sony Vaio AR Series",
            .callback = sony_nc_C_enable,
            .driver_data = sony_C_events,
            .matches = {
                DMI_MATCH(DMI_SYS_VENDOR, "Sony Corporation"),
                DMI_MATCH(DMI_PRODUCT_NAME, "VGN-AR"),
------- end paste -----

to the appropriate section in drivers/misc/sony-laptop.c, but that's
about all that works.

I get no controls in /sys/devices/platform/sony-laptop. I do get a few
controls in
/sys/class/backlight/sony, but they don't seem to do anything.
(I get these: actual_brightness bl_power brightness max_brightness).

Any suggestions?

Great, I can add this laptop to the list.

Could you send the output of lspci and upload somewhere the DSDT (or
send me provately as I'm not sure about the limits for postings to this
list).

01:00.0 VGA compatible controller: nVidia Corporation G86M [GeForce 8400M GT] (rev a1)

eh... this is known not to be working with sony-laptop. Even though the
DSDT exposes the brightness methods the nvidia cards have their own way
to handle dimming the screen.
You can try with nvclock which works for *some* cards.

For now all sony-laptop can do is enable the Fn keys, I'll add your
model to the DMI list asap.

Thanks, I'll try nvclock.

Any chances of getting the rest of the controls working? (like turning
on bluetooth and so on)

well, not until somebody is able to trace which SNC device methods (if
any at all) are called to control the extra features.
Unfortunately there are no specs available for it.
