Please attach DSDT. Sound like we need a generic solution. Created attachment 4263 [details]
this is my /proc/acpi/dsdt file
this is my /proc/acpi/dsdt file
tosiba_acpi.c rely on : #define METHOD_LCD_BRIGHTNESS "\\_SB_.PCI0.VGA_.LCD_._BCM" #define METHOD_HCI_1 "\\_SB_.VALD.GHCI" #define METHOD_HCI_2 "\\_SB_.VALZ.GHCI" #define METHOD_VIDEO_OUT "\\_SB_.VALX.DSSX" The attached DSDT don't have those method. So you need to look for other solution for this toshiba's hot key. Could you describe the details of them? Maybe my generic hotkey driver can help. why, don't have the attached DSDT those method??? these kind of details?? tell me if not!

generic hotkey driver
With the enclosed patch, I enabled hotkey on ASUS2400 NE using the following
commands:
echo "0:\\_SB.ATKD::\\_SB.ATKD:INIT:1:1" > /proc/acpi/hotkey/ev_config :
Install hotey.
echo "1:1:0" > /proc/acpi/hotkey/action : Execute INIT method of Hotkey.
Without any specific driver, the hotkey functions work on this laptop.
So, I think you can config the driver through interfaces listed in
/proc/acpi/hotkey with respect to your specific DSDT.
Basically, acpi implement hotkey functionality through _Qxx or _Lxx (_Exx).
And, there could have Notify op to be used to notify OSPM for hotkey event.
This generic hotkey driver provide way to configure which acpi bus to notify
for a specific hotkey,
and way to call AML method for any specific purpose of enabling hotkey.
And, it also try to implement translation of specific hotkey event number to
standardized event number.
