Como posso fazer com que a taxa de repetição do meu teclado seja aplicada a um teclado USB hotplugged?
Eu fiz uma regra do udev para definir o atraso e taxa de repetição do teclado, /etc/udev/rules.d/99-usb-keyboard.rules com o seguinte conteúdo:
ACTION=="add", SUBSYSTEM=="usb", RUN+="/home/michael/bin/keyboard_settings.sh"
keyboard_settings.sh:
#!/bin/bash
# Set keyboard repeat delay and rate
xset -display :0.0 r rate 250 40
O udev parece ver isso, usando o comando udevadm test /sys/bus/usb/devices/3-2\:1.0/
read rules file: /etc/udev/rules.d/99-usb-keyboard.rules
rules contain 393216 bytes tokens (32768 * 12 bytes), 37438 bytes strings
31709 strings (264322 bytes), 28154 de-duplicated (230440 bytes), 3556 trie nodes used

E, no entanto, isso não altera a taxa de repetição. O teclado do laptop tem as configurações corretas, mas o teclado USB externo não. O Xorg sobrescreve as configurações depois que a regra do udev é aplicada? Como posso descobrir?
Eu recebo isso no Xorg.0.log, indicando que o X11 está mexendo com as coisas, mas nenhuma das regras em /usr/share/X11/xorg.conf.d/ faz nada com teclados.
