(...) This usually comes in form of a kernel module (for instance, I can locate "toshiba_acpi.ko" and "toshiba.ko") which allows acpi events to be triggered when hitting the corresponding function keys. As you can guess, the kernel module names vary depending on the manufacturer (there are modules for HP, Asus, Toshiba, Sony, Dell, etc... notebooks). In brief, I would check if the kernel modules are loaded in the netbooks where pressing the brightness key produces no result. Also, review the dmesg log, maybe there's something hanging there (e.g., "dmesg | grep -i - e acpi -e toshiba") Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
