Title: [udev] changing hwdb requires calling udevadm control --reload Status in systemd package in Ubuntu: Won't Fix Bug description: I have a small gaming keyboard (Ideozon Fang) which has a terrible default keymapping that I want to fix. To do that, I need to change its default keymapping. But only for that keyboard and no other. My system is Ubuntu 14.04 (amd64). As an example, I will change the key '3' which is by default mapped to 'Numpad 3' to 'PgDn'. The old way that used to work (and still does in Debian 7.6) was this: <----- snip -----> root@debian~# /lib/udev/keymap -i /dev/input/event7 Press ESC to finish, or Control-C if this device is not your primary keyboard scan code: 0x7005B key code: kp3 root@debian~# cat /etc/udev/keymaps/ideazon-zboard 0x7005B pagedown root@debian~# /lib/udev/keymap /dev/input/event7 /etc/udev/keymaps/ideazon-zboard Remapped scancode 0x7005b to 0x6d (prior: 0x51) root@debian~# evtest /dev/input/event7 Input driver version is 1.0.1 Input device ID: bus 0x3 vendor 0x1038 product 0x310 version 0x111 Input device name: "Ideazon Zboard USB Gaming Device" [...] Event: time 1408993871.777960, type 4 (EV_MSC), code 4 (MSC_SCAN), value 7005b Event: time 1408993871.777971, type 1 (EV_KEY), code 109 (KEY_PAGEDOWN), value 1 <----- snap -----> However, this method does not work anymore in 14.04 (for instance, there is no 'keymap' utility). Now, if I researched it correctly, we are supposed to do this: <----- snip -----> root@ubuntu:~# lsusb | grep -i ideazon Bus 003 Device 009: ID 1038:0310 Ideazon, Inc. root@ubuntu:~# cat /etc/udev/hwdb.d/91-local-ideazon-zboard.hwdb keyboard:usb:v1038p0310* KEYBOARD_KEY_07005b=pagedown root@ubuntu:~# udevadm hwdb --update root@ubuntu:~# evtest /dev/input/event6 Input driver version is 1.0.1 Input device ID: bus 0x3 vendor 0x1038 product 0x310 version 0x111 Input device name: "Ideazon Zboard USB Gaming Device" [...] Event: time 1408993986.205654, type 4 (EV_MSC), code 4 (MSC_SCAN), value 7005b Event: time 1408993986.205654, type 1 (EV_KEY), code 81 (KEY_KP3), value 1 <----- snap -----> But, as you can see, it does not work. 'evtest' still reports the key as 'Numpad 3'. Even unplugging and re-plugging the keyboard has no effect. 'udevadm' seems to compile my custom file alright (it complains if I purposefully put a syntax error in it). But I still cannot redefine my keymap. I do not know if this is a problem of the newer udev itself. But even if it is, Ubuntu should not use it until it actually works. Especially not in a LTS version.
