** Description changed: I have a problem with my system, i think it's a kernel issue because light sensor stop to respond after kernel load. For example, when i am in the GRUB menu, light sensor work correctly and i can enable and disable sensor with FN+left arrow, but when kernel starts to load, without any module loaded (i stop loading to an emergency shell, so i eliminate issues concerning modules or any other software, i.e. gnome-power-manager), light sensor stops to work. I test my pc with a CentOS 5.5 live (kernel 2.6.18) and it's OK, also in emergency shell, if i try with CentOS 6 (kernel version over 2.6.30) the issue is present, so i think it's a kernel regression, but i'm not sure. My collegue with a Dell Latitude XT (it's an older series) has not the issue, its ambient light sensor works fine. with lsinput i identify the Dell Wky Hotkeys and if i check with /lib/udev/keymap -i input/event6 i read: scan code: 0x4B key code: unknown So is this a problem related to dell_wmi? What can i do to identify the issue more precisely?
