Como posso substituir minhas regras do udev de teclado e mouse com xorg.conf.d?

Question

Como é impossível fazer com que as regras do udev que afetam as configurações do Xorg sejam executadas na inicialização , eu gostaria de substituí-las com outras alternativas. No momento, tenho dois scripts principais do udev que eu escrevi. A primeira altera o layout do teclado quando o teclado é conectado ou removido, além de iniciar xcape . O segundo retarda o ponteiro quando um mouse específico é conectado, e também permite a entrada do mouse para acordar o computador.

Estou usando o (K) Ubuntu 13.04. As regras e scripts do udev seguem, assim como os xmodmaps.

/etc/udev/rules.d/00-teck.rules :

ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="0e6a", ATTR{idProduct}=="030c", RUN+="/usr/local/bin/TECK_connect"
ACTION=="remove", SUBSYSTEM=="usb", RUN+="/usr/local/bin/TECK_disconnect"

#!/usr/bin/env bash

export DISPLAY=:0.0
cp -f /home/sparhawk/HDD/Computer/Xmodmaps/Xmodmap_for_TECK /home/sparhawk/.Xmodmap

  sudo -u sparhawk pkill xcape

Answer 1

Para substituir o xcape, eu instalei o modificador , que faz uma coisa semelhante, mas um nível de raiz. Ele tem a vantagem adicional de ser configurado pelas regras do xorg, permitindo que ele opere somente em teclados específicos.

Por isso, /etc/X11/xorg.conf.d/11-TECK-keymap.conf contém

Section "InputClass"
  Identifier "TECK"
  Driver "evdev"
  Option "XKBOptions" "terminate:ctrl_alt_bksp" # and so on

  # If you save this file under xorg.conf.d/ :
  Option "AutoServerLayout" "on"

  MatchIsKeyboard "on"
  MatchProduct "TrulyErgonomic.com Truly Ergonomic Computer Keyboard"

  ### at-home-modifier options begin here.
  # The basic option.
  Option "XkbLayout" "us"
  Option "XkbVariant" "altgr-intl"
  Option "XKbOptions" "lv3:ralt_switch_multikey,numpad:pc"
  Option "TransMod" "36:64" # Defines key/modifier pairs. Use xev. e.g. Enter (real key):Alt (virtual key).
EndSection

Para os mapas de teclado, eu usei o recém-lançado software para reconfigurar o firmware (embora eu possa ter modificado /usr/share/X11/xkb/keycodes/evdev ). Para as chaves AltGr , modifiquei diretamente /usr/share/X11/xkb/symbols/us , substituindo as entradas na seção xkb_symbols "intl" {

eu substituí

key <AE11> { [ minus, underscore, yen, dead_belowdot ] };

com

key <AE11> { [ minus, underscore, endash, emdash ] };

e

key <AB09> { [ period, greater, dead_abovedot, dead_caron ] };

com

key <AB09> { [ period, greater, ellipsis, dead_caron ] };

Em seguida, apaguei as configurações do xkb em cache em /var/lib/xkb/*.xkm conforme esta resposta e reiniciei.

Ainda não sei como fazer o brilho do controle Fn + F5 e Fn + F6 ( XF86MonBrightnessDown e XF86MonBrightnessUp )
