Saya menjalankan Ubuntu 9.10 (Karmic Koala) di laptop dan ingin NumLock untuk secara otomatis beralih tergantung pada apakah keyboard USB saya terhubung (numlock on) atau dicabut (numlock off).
Untuk mencapai ini, saya pertama kali menginstal paket "numlockx". numlockx on
dan numlockx off
bekerja dengan baik.
Untuk menghubungkan ke sistem perangkat, saya pikir saya akan menggunakan udev. Saya telah membaca "Menulis aturan udev" , tetapi saya mengalami masalah dalam menjalankan aturan udev.
Pertama, inilah contoh dmesg
outputnya:
[20906.985102] usb 3-2: perangkat USB kecepatan rendah baru menggunakan uhci_hcd dan alamat 6 [20907.166403] usb 3-2: konfigurasi # 1 dipilih dari 1 pilihan [20907.192904] masukan: Microsoft Natural® Ergonomic Keyboard 4000 sebagai /devices/pci0000:00/0000:00:1a.0/usb3/3-2/3-2:1.0/input/input20 [20907.193100] microsoft 0003: 045E: 00DB.000B: input, hidraw1: USB HID v1.11 Keyboard [Microsoft Natural® Ergonomic Keyboard 4000] di usb-0000: 00: 1a.0-2 / input0 [20907.217810] masukan: Microsoft Natural® Ergonomic Keyboard 4000 sebagai /devices/pci0000:00/0000:00:1a.0/usb3/3-2/3-2:1.1/input/input21 [20907.217979] microsoft 0003: 045E: 00DB.000C: input, hidraw2: Perangkat USB HID v1.11 [Microsoft Natural® Ergonomic Keyboard 4000] di usb-0000: 00: 1a.0-2 / input1
Saya biasa udevadm info
mengumpulkan info perangkat:

Jadi saya membuat file bernama /etc/udev/rules.d/usb-keyboard.rules
:
# Nyalakan NumLock saat keyboard dicolokkan. ACTION == "add", ATTRS {manufacturer} == "Microsoft", SUBSYSTEM == "input", RUN + = "/ usr / bin / numlockx on" # Matikan NumLock saat keyboard dicabut. ACTION == "hapus", ATTRS {manufacturer} == "Microsoft", SUBSYSTEM == "input", RUN + = "/ usr / bin / numlockx off"
Saya sudah terbiasa udevadm test
memverifikasi bahwa aturannya benar:

Masalahnya adalah ketika keyboard dicolokkan atau dicabut, status NumLock tidak berubah. Saya telah mencoba memulai kembali layanan udev, tanpa hasil. Apakah aturan udev saya salah? Apakah saya salah tentang hal ini?
