[ltp] hotkey brightness problem

[Riccardo Paterna]

Hi List,
i'm using gentoo with thinkpad-source i have some problem with
brightness keys...
If i use acpi_listen when i use the brightness key i don't see any signal
I'm using the latest ibm-acpi extra driver and in my dmesg i see :

thinkpad_acpi: Disabling thinkpad-acpi brightness events by default...
thinkpad_acpi: Lenovo BIOS switched to ACPI backlight control mode
thinkpad_acpi: standard ACPI backlight interface available, not loading
native one...


How i can fix this and have brightness keys working?

Thanks a lot

Regards
