How to set up Ubuntu to instantly transform NumLock on when an exterior key-board is affixed and also off when it is not?
Having NumLock on is hassle-free when making use of a complete - sized exterior key-board (having a keypad) and also really bothersome when making use of laptop computer is constructed - in key-board (which positions figures as opposed to letters on the key-board is appropriate sid unless Fn is pushed).
So I need to transform NumLock on every single time I attach an exterior key-board (or boot with it affixed) and also off every single time I detach an exterior key-board (or boot with it separated). And also I do this regularly due to the fact that I favor making use of a complete - sized exterior key-board, yet have not nearly enough (just 3) USB ports to connect - in it alongside with a computer mouse, a 3G modem and also an exterior hard/flash drive.
Can I automate this? Appears a really formaliseable, practically straightforward job : if there is an USB key-board affixed (some tool in/ dev existing?) - NumLock gets on, otherwise - NumLock is off. My laptop computer is constructed - in key-board is PS/2 - affixed, exterior is USB.
Possibly I should code it myself, yet where to place it in this instance?
I make use of Ubuntu 10.10.
I'm not exactly sure what I'm doing in different ways, due to the fact that my numlock on this key-board is failing to on (This is a Mac Pro Aluminum key-board). There are some instructions here that needs to suffice.
Hope this aids!
First off, install numlockx (click here to install numlockx). Primarily this permits you to write manuscripts to set the state of Num Lock - see the numlockx man page for information.
Next we require to start diving right into the enjoyable of udev regulations. First we require to figure out just how the key-board is recognized. You can do this by
ls /dev/input/by-id/
This needs to offer you some human legible documents names (that are soft links to the not specifically legible real name). My key-board was
/dev/input/by-id/usb-KINESIS_FREESTYLE_KB700_KB700_Kinesis_Freestyle-event-kbd
So after that we require to figure out all the details concerning the key-board. I did
udevadm info -a -p $(udevadm info -q path -n /dev/input/by-id/usb-KINESIS_FREESTYLE_KB700_KB700_Kinesis_Freestyle-event-kbd)
But insert your very own path there certainly. You'll get a great deal of details, yet you intend to consider the first block that names the key-board and also has SUBSYSTEMS=="usb". (Rather than the USB controller or whatever). In my instance that was:
looking at parent device '/devices/pci0000:00/0000:00:1a.0/usb3/3-2/3-2.3':
KERNELS=="3-2.3"
SUBSYSTEMS=="usb"
DRIVERS=="usb"
ATTRS{configuration}==""
ATTRS{bNumInterfaces}==" 2"
ATTRS{bConfigurationValue}=="1"
ATTRS{bmAttributes}=="a0"
ATTRS{bMaxPower}==" 50mA"
ATTRS{urbnum}=="6284"
ATTRS{idVendor}=="058f"
ATTRS{idProduct}=="9410"
ATTRS{bcdDevice}=="0122"
ATTRS{bDeviceClass}=="00"
ATTRS{bDeviceSubClass}=="00"
ATTRS{bDeviceProtocol}=="00"
ATTRS{bNumConfigurations}=="1"
ATTRS{bMaxPacketSize0}=="8"
ATTRS{speed}=="1.5"
ATTRS{busnum}=="3"
ATTRS{devnum}=="3"
ATTRS{devpath}=="2.3"
ATTRS{version}==" 1.10"
ATTRS{maxchild}=="0"
ATTRS{quirks}=="0x0"
ATTRS{avoid_reset_quirk}=="0"
ATTRS{authorized}=="1"
ATTRS{manufacturer}=="KINESIS FREESTYLE KB700"
ATTRS{product}=="KB700 Kinesis Freestyle"
So currently we have adequate details to write some regulations. Utilize your favorite editor to create /etc/udev/rules.d/10-local.rules and also place in:
BUS=="usb",ATTRS{product}=="KB700 Kinesis Freestyle",ACTION=="add",RUN+="/usr/bin/numlockx on"
BUS=="usb",ATTRS{product}=="KB700 Kinesis Freestyle",ACTION=="remove",RUN+="/usr/bin/numlockx off"
Again, placed the name of your key-board in below, and also the ATTRS if it is various. After that it needs to function:)
Note I have not had the ability to examine this, though I have actually run all the commands up till developing the regulations submit. And also the resources in instance you require to do some even more examination are:
