I'm learning Signals, and I have a question:
Is possible to make a handle when I press any of the keyboard buttons?
The SIGINT handles the Ctrl-C combination, but I want to handle if any keyboard button was pressed.
When I boot, apparently any Linux (Ubuntu and CloneZilla), I see the letters Code: ^]]B scroll pass, over and over again. This represents the down key as when I try to do anything the down key is held down. This occurs during boot on Ubuntu (once I get to the login screen it stops and does not happen). This does not happen at the GRUB screen or in Windows. It also occurs during the entire CloneZilla process and Ubuntu alternative install process (making both of these impossible)
I can't find any reason for this to happen and have been using both CloneZilla and Ubuntu for a long time before this happened. Does anyone know what I could try to fix this.
Ubuntu no longer boots.
A friend of mine has an old emachines with XP on it and at first it would complain it had to test the disk and turn off in less then a minute. Now it won't do anything except run the power supply and cpu fans while the start button is pressed. I checked for power on the blue , purple ,red and orange wires while 14 and 15 were jumped on the power supply. There are no lEDs on the board and no beeps. I disconnected all the peripherals also

When I press the power button, I see a dialogue box which asks for confirmation and if nothing is confirmed system automatically shuts down in 60 seconds.
I want to change this time of 60 seconds to say 30 seconds. Is it possible? Also is there a way to hide that dialogue box...
I have a dell zino inspiron media pc with Ubuntu 10.04 installed. I am able to shutdown using the power button on machine i.e. System->Preferences->Power Management option 'when power button is pressed': choose 'Shutdown'.But for option 'when suspend button is pressed', I only get 'Suspend' or 'Hibernate' in the drop-down. Where is my 'Shutdown' option?I really want to be able to shutdown my machine from my wireless keyboard!

Code:
pthread_t Timer::Init(long _clock_interval_musec)

// Set interval.
clock_interval = _clock_interval_musec;
// This is called while in a single threaded environment.

clock_interval is 50.
Is the timer not firing? Did I not set my interval correctly? Did I not proper block the signals ensuring the that the default handler would not take care of them?
I have a Microsoft Wireless Desktop 3000 (Wireless Keyboard 3000 + Wireless Mouse 5000), actually, I have two of them, one in this computer, running Ubuntu 10.10 and another one in a box running Ubuntu 10.04.In the box running 10.04 I can perfectly use 70% of the hotkeys the keyboard has, the 30% left I guess they're not compatible, but that's not a problem.In the one running 10.10 whenever I use a hotkey,t works, but,sametimet "blocks" the mouse left button in the 'pressed' state. Let me be more clear, it's like I'm holding down the left click all the time and I don't ever release it. Unless I restart the system, I can't recover the left click.

The mouse buttons on my machine are frustratingly loud, unreliable and hard to press down. (the touchpad thingy that *moves* the mouse works great though)
I would like to map a certain (unused) keyboard key I have, to do the job that the left mouse button does (i.e. the opposite of what tons of mouse-keyboard mapping programs do).
I'm open for suggestions on how to accomplish this, but I would prefer using xmodmap, possibly in conjunction with xdotool. Thus, I need someway to map events as follows: (button1=leftmouse; keycode123=keyboard key alternative)
KeyPress 123 ---> ButtonPress Button 1
Keyrelease 123 ---> ButtonRelease Button 1
Compiz is also a great way to map stuff to xdotool commands, but it doesn't handle separate KeyDown/KeyUp event.
I recently upgraded to Jessie and am using the LXDE desktop. I like using the keyboard power button to shutdown the system but it does not work. I looked at /etc/acpi and everything appears okay to my untrained eyes, but there is obviously something not working correctly. Do I need to edit some config file or install some code in order to use the power button for shutdown ? When I look at Services Settings I see that acpid power management is selected.

View 2 Replies View RelatedYesterday night everything was normal until I rebooted to Fedora. This morning I switched back to Kubuntu 9.04 and the keyboard had a strange behaviour. Every button needs to be pressed ~2 sec. in order the letter to show up. And that happens in every application (shell, firefox, etc). I tried to upgrade to 9.10 hoping that it will return to defaults but the problem persist. Please help solve this issue, my work is hanging and all the programs I'm using at the moment are installed on my Ubuntu partition.
View 4 Replies View RelatedI have a Genius K627 Keyboard with Power, Sleep and Wake buttons. ACPI is unsupported on my computer, but it can turn off its power supply when the system halts (PM is ok). I would like to bind the Power key on the keyboard to execute the /sbin/halt command. What I already know is that I can specify an event in inittab (kbrequest) that would execute a command. What I don't know how I can make my system receive pressing Power button as a kbrequest. The scancodes of Power button on the keyboard (by showkey): 0x74 0xf4
This is the line I was talking about in my inittab:
Code:
ce:12345:kbrequest:/sbin/halt
I think I should edit /etc/console/boottime.kmap.gz but don't know how I could insert this scancode into it.

My knowledge on programming is very low but I'm opend for learning.
View 1 Replies View RelatedI am currently using xmodmap for remapping keys like Caps Lock on my keyboard.However, my keyboard has a bunch of keys on the top that are rarely used (Multimedia keyboard with buttons like Internet, Music, Next song, Mute etc)I want to remap these keys to specific commands (Not keys).
For example: Pressing the Internet button should fire up my Firefox (/usr/bin/firefox)(which happens only in Windows for me)Also I need to map a specific button to xkill.
Is there any keyboard shortcut that mimics the 'win' button operation in windows?got it..i should search a bit before asking..

I have a file with 200 000 lines and I want to append the fields of each line based on matching first field. The resulting file should have 70 000 columns but has "only" 18 000. The command I'm using is working perfectly with a smaller file, wich lead to 14 000 columns. Could there be a limit in number of fields that awk can handle ? Here's my awk command :
Code:
awk -F, 'END { for (k in _) print _[k] } { _[$1] = $1 in _ ? _[$1] FS $4 : $1","$4 } ' file > out
Also, this command writes ^M (windows line break) after each columns. Removing them is easy but where do they come from ? Working on Ubuntu 10.10
I want to install Linux on my laptop. I started with Arch but 4 hours later, I'll take anything so now I'm trying Ubuntu.It appears that the keyboard function button that corresponds to my wireless does not work, and perhaps is windows dependent?Every time I try to interact with wlan0, I get the error "Operation not possible due to RF-kill". And as I've looked around online, it has been suggested in other forums that the only way to resolve this is to reinstall windows and dual boot, so the FN key will work.
I think this is ridiculous. There must be a way to persuade the RF-kill to be turned off again, shouldn't there?I don't have a recover disk for this laptop and I don't want to go through the trouble of requested one from acer. I reformatted the whole disk while attempted to install arch.

I installed Ubuntu 9.10 on a new acer emachine e525. All is fine except that now I cannot switch the wireless on as the button above the keyboard no longer functions. Can anyone tell me what I can do to fix this as wireless is obviously vital in a laptop. BTW the wireless waqs working fine while the machine had Vista on it.
