Hello,
I've got a new laptop, some features are not working yet:
* Bluetooth (Device deactivated)
* Backlight Brightness (Can not be tuned)
* Hotkeys (nothing happens)
* Maybe more, don't know.
The current acer-wmi driver does not recognize my WMI interface, but seems to
be partially compatible.
WMID_GUID3 exists on my system and appears to work with acer-wmi.
The other GUIDs do not exist, hence the driver needs some modifications.
While playing around, I discovered the following:
The only data object, 05901221-D566-11D1-B2F0-00A0C9062910 (WQAB) is a blob of
binary data, 4392 (0x1128) bytes long, with a 16 byte header:
46 4f 4d 42 (FOMB in ascii. Wth is FOMB?)
01 00 00 00
18 11 00 00 (size of following data without header?)
9e 6d 00 00
WMID_set_capabilities expects an integer or a 4/8 byte buffer instead.
The events received from 676AA15E-6A47-4D9F-A2CC-1E6D18D14026 are 8-byte
buffers; I have found these values:
04 xy xy 00 00 00 00 00 Backlight Brightness, xy xy == 00 00 .. 09 09. If I
press Fn-Left/Right in Gnome, I get the on screen display and the event fires.
But no change to the actual brightness happens.
01 23 00 00 00 00 00 00 Key "P" (Programmable key) (1st key right of
powerswitch)
01 21 00 00 00 00 00 00 Key "Acer Backup Manager" (2nd key right of
powerswitch)
01 62 00 00 00 00 00 00 Backlight enable/disable (Fn-F6) or sometimes(?!) lid
open
01 82 18 00 00 00 00 00 Touchpad disabled (with Fn-F7)
01 82 1a 00 00 00 00 00 Touchpad enabled (with Fn-F7)
acer_wmi_enable_lm(); wmid3_set_device_status(1, 0x800); turns on the bluetooth
adapter, but most of the detection code does not work for my laptop.
Please tell me if there is anything else (e.g. testing) I could do; thank you!
