Description of problem: I've got a new Dell laptop that I've installed F19 on. When using the brightness down/up hotkeys (FN-F4/FN-F5), each key registers three times. The three times happen from: - the dell-wmi module (if I rmmod that, I get only two key presses) - the systemd keymaps for dell laptops (if I use the keymap util to map those keys from brightness{up,down} to unknown, that removes another key press) - ACPI Version-Release number of selected component (if applicable): systemd-204-9.fc19.x86_64 kernel-3.9.9-302.fc19.x86_64 How reproducible: Always Steps to Reproduce: 1. Press fn-F[45] while in X. Actual results: XFCE brightness monitor goes in steps of 3 Expected results: XFCE brightness adjusts in steps of 1 Additional info: I can use the panel app (or echoing to the appropriate sysfs file) to set the brightness manually - this is solely a key-related issue (I have to boot with acpi_backlight=vendor for that, though) The dell-laptop and i8k modules are loaded, but doesn't seem to make a difference either way showkey -s output: press any key (program terminates 10s after last keypress)... 0xe0 0x4c 0xe0 0xcc 0xe0 0x4c 0xe0 0xcc 0xe0 0x4c 0xe0 0xcc 0xe0 0x4c 0xe0 0xcc 0xe0 0x4c 0xe0 0xcc 0xe0 0x4c 0xe0 0xcc 0xe0 0x54 0xe0 0xd4 0xe0 0x54 0xe0 0xd4 0xe0 0x54 0xe0 0xd4 0xe0 0x54 0xe0 0xd4 0xe0 0x54 0xe0 0xd4 0xe0 0x54 0xe0 0xd4 0xe0 0x4c 0xe0 0xcc 0xe0 0x4c 0xe0 0xcc 0xe0 0x4c 0xe0 0xcc 0xe0 0x4c 0xe0 0xcc 0xe0 0x4c 0xe0 0xcc 0xe0 0x4c 0xe0 0xcc /usr/lib/udev/keymap -i input/event3 : Press ESC to finish, or Control-C if this device is not your primary keyboard scan code: 0x85 key code: brightnessdown got scan code event 0x85 without a key code event scan code: 0x86 key code: brightnessup got scan code event 0x86 without a key code event scan code: 0x01 key code: esc # acpi_listen PNP0C14:00 000000d0 00000000 video/brightnessup BRTUP 00000086 00000000 video/brightnessdown BRTDN 00000087 00000000 PNP0C14:00 000000d0 00000000 (first two lines are from me pushing the UP combination; last two are pressing the DOWN one once.
