-= The udev keymap tool =
-
-== Introduction ==
-
-This udev extension configures computer model specific key mappings. This is
-particularly necessary for the non-standard extra keys found on many laptops,
-such as "brightness up", "next song", "www browser", or "suspend". Often these
-are accessed with the Fn key.
-
-Every key produces a "scan code", which is highly vendor/model specific for the
-nonstandard keys. This tool maintains mappings for these scan codes to standard
-"key codes", which denote the "meaning" of the key. The key codes are defined
-in /usr/include/linux/input.h.
-
-If some of your keys on your keyboard are not working at all, or produce the
-wrong effect, then a very likely cause of this is that the scan code -> key
-code mapping is incorrect on your computer.
-
-== Structure ==
-
-udev-keymap consists of the following parts:
-
- keymaps/*:: mappings of scan codes to key code names
-
- 95-keymap.rules:: udev rules for mapping system vendor/product names and
- input module names to one of the keymaps above
-
- keymap:: manipulate an evdev input device:
- * write a key map file into a device (used by udev rules)
- * dump current scan → key code mapping
- * interactively display scan and key codes of pressed keys
-
- findkeyboards:: display evdev input devices which belong to actual keyboards,
- i. e. those suitable for the keymap program
-
-== Fixing broken keys ==
-
-In order to make a broken key work on your system and send it back to upstream
-for inclusion you need to do the following steps:
-
- 1. Find the keyboard device.
-
- Run /usr/lib/udev/findkeyboards. This should always give you an "AT
- keyboard" and possibly a "module". Some laptops (notably Thinkpads, Sonys, and
- Acers) have multimedia/function keys on a separate input device instead of the
- primary keyboard. The keyboard device should have a name like "input/event3".
- In the following commands, the name will be written as "input/eventX" (replace
- X with the appropriate number).
-
- 2. Find broken scan codes:
-
- sudo /usr/lib/udev/keymap -i input/eventX
-
- Press all multimedia/function keys and check if the key name that gets printed
- out is plausible. If it is unknown or wrong, write down the scan code (looks
- like "0x1E") and the intended functionality of this key. Look in
- /usr/include/linux/input.h for an available KEY_XXXXX constant which most
- closely approximates this functionality and write it down as the new key code.
-
- For example, you might press a key labeled "web browser" which currently
- produces "unknown". Note down this:
-
- 0x1E www # Fn+F2 web browser
-
- Repeat that for all other keys. Write the resulting list into a file. Look at
- /usr/lib/udev/keymaps/ for existing key map files and make sure that you use the
- same structure.
-
- If the key only ever works once and then your keyboard (or the entire desktop)
- gets stuck for a long time, then it is likely that the BIOS fails to send a
- corresponding "key release" event after the key press event. Please note down
- this case as well, as it can be worked around in
- /usr/lib/udev/keymaps/95-keyboard-force-release.rules .
-
- 3. Find out your system vendor and product:
-
- cat /sys/class/dmi/id/sys_vendor
- cat /sys/class/dmi/id/product_name
-
- 4. Generate a device dump with "udevadm info --export-db > /tmp/udev-db.txt".
-
- 6. Send the system vendor/product names, the key mapping from step 2,
- and /tmp/udev-db.txt from step 4 to the linux-hotplug@vger.kernel.org mailing
- list, so that they can be included in the next release.
-
-For local testing, copy your map file to /usr/lib/udev/keymaps/ with an appropriate
-name, and add an appropriate udev rule to /usr/lib/udev/rules.d/95-keymap.rules:
-
- * If you selected an "AT keyboard", add the rule to the section after
- 'LABEL="keyboard_vendorcheck"'.
-
- * If you selected a "module", add the rule to the top section where the
- "ThinkPad Extra Buttons" are.
