Ctrl-key not working properly under Linux

Hello,
I am using Labview 8.6 under Ubuntu Linux 8.10 (Gnome) with a German keyboard layout.  If I want to enter a backslash "\" and hit the control-key I first get one ore more space-characters. This is very annoying and produces sometimes hard to find typing errors. I don't have such problems with any other applications so the keyboard settings of Gnome/X-server seem to be fine.
Any help would be appreciated.

Okay.  It was just a thought of where there might be a problem with LabVIEW and doing a Ctrl-S for save being a problem, but not for other apps.
I don't have any other ideas right now.  I don't do Linux and it seems like that is where your problem lies.  I don't have the time or desire anymore for the sake of trying to make non-conventional operating system with a myriad of flavors and versions functional, so I stay away from it.
Good luck.  Hopefully those people who love to dive into the nitty gritty details of an operating system like Linux have some ideas.

  • Ctrl key not working properly

    Hi,
    I have an HP Pavilion 17-e031sa Notebook PC purchased only 2-weeks ago and running Windows 8.  The ctrl key is not working as it should.  I would typically use it together with the left mouse key to highlight non-consecutive items for copying, but it will not work for this function.  It doesn't seem to be the key itself as it does work in the alt/ctrl/del combination.  I have tried uninstalling the keyboard driver and rebooting, but without success.  Any help would be appreciated.

    Hi riggy69,
    Sorry for the confusion, I knew those hotkeys wouldn't do the function you were looking for. I wanted to know if those shortcuts worked using the Ctrl key. This way we can see if it that particular function is working or all the ctrl key shortcuts are working. Did any hotkeys do what they were supposed to do? For example, does Ctrl+X cut the selected text or does Ctrl-Esc open the start menu?
    Trying to see if there is something wrong with the key itself or is someone is wrong with that particular function you are trying.

  • Windows 7 Brightness and Function key not Working Properly

    i have HP 15-af024AU APU Quad Core A8-7410 - (4 GB DDR3,1 TB HDD) Noteboook and it  came with windows 8.1 preinstalled than i installed windows 7 ultimate.
    i have problem in Display Brightness i am not able to change Brightness by function key or by manually from windows settings.
    2. my Function key are not working properly . all key are fliped whiout holding function key it work as function key. 3. bluetooth is not working when i search for new device not able to find any available discouable bluetooth device. 4. wireless button software is not wokring in windows 7 i already updated my bios that available in drivers support and install alll drivers too properly so please give proper drivers for windows 7 for this product that works perfect.

    Sorry that driver didn't work. You can try this graphics driver and if that doesn't work, unfortunately, I won't be able to help you with that issue. This package provides the AMD High-Definition (HD) Graphics Driver and Catalyst Control Center for supported notebook models that are running a supported operating system. For notebooks with switchable graphics modes, this package includes drivers for both graphics processing units (GPUs). Switchable graphics enable users to switch between a power-saving graphics mode (normally used under battery power) and a high-performance graphics mode. If high-definition multimedia interface (HDMI) video output is supported, this package also installs the HDMI Audio Driver. File name: sp71253.exe As far as the Fn keys being 'flipped,' I have no idea what you mean by that, or what to do about it. Did you install the software that controls the funtion keys? This package contains the HP System Event Utility, which enables special function keys on supported notebook models to be programmed. For example, HP System Event Utility enables users to press the Fn+ESC keys to view system information. This software works with the supported operating systems. File name: sp71156.exe

    Hello:
    I do not know of a setting that would do that - especially intermittently.
    I would suspect the KB is failing/has failed.

  • Shift key and ctrl keys not working correctly...

    both rt/lt shift keys are making symbols ⁄€‹›fifl‡ÎÔÇ´ instead of caps and my ctrl key asks me if i really want to shut down my computer. i'm really hoping this is an easy fix but can't find anything in forums. if additional information is needed please let me know. HELP PLEASE

    Hi, Chris. I don't know of any. If there were a way, I'm sure it would require that all the keys be working properly, which yours aren't. You've got crossed wires somewhere, and you're going to need a replacement keyboard.

  • Key not working properly

    I bought E-71 about one month back. I upgraded its software to 110.07.127. After this upgrade process, the keys are not working properly.
    For example, the key titled '?' is not printing '?' while another key titled '.' is printing '?'. This problem is for the whole keypad.
    FYI, my keypad also contains the Arabic letters. They are also not working after this upgrade.
    Software upgrade is done from the following link: http://www.nokia.co.in/A4767968
    Thanks a lot in advance for the kind support.

  • 2007 MacBook Pro ctrl key not working

    Hi all,
    I have used various iterations of bootcamp with my 2007 macbook pro without problem. I have also sucessfully installed Windows 7 64-bit using bootcamp and got it working almost perfectly (sound, video, magic mouse) despite it not officially being supported by the version of bootcamp that came with Snow Leopard.
    My only problem now is that the control lkey isn't working. I've tried various keymappers to map it to another key (generally the Apple key) to no avail. And when I say it isn't working, I mean it's not working at all. Key mappers don't recognise when I tap it, I can't Ctrl-C to copy or Ctrl-anything to anything.
    I have installed the Apple keyboard driver and everything else works perfectly, including the F-keys, Fn, alt and the Apple key (which opens the start menu). Any suggestions for how I could fix this would be greatfully received.
    Thanks,
    Alexis

    Sadly it turns out that it's not working in OS X either. I had convinced myself it was a software issue but it is apparently hardware. Shows how seldom the control key's used in OS X doesn't it.
    If anyone has any suggestions as to how I might have a bash at fixing it, please let me know.
    Thanks,
    Alexis

  • Portege R500 - Ctrl Key not working

    Hi Guys
    I have two toshiba portege r500 which have never really be used since purchase about 2 years ago.
    Today I get one out to start using it and find the ctrl key is not working which I thought was strange.
    After a little browsing I could not find a solution so I simply got the other identical laptop out and starting using that only to find the exact some problem.
    The laptops are both running XP.
    One of which I have reformatted and uninstalled the keyboard driver to see if that would solve the problem but it did not.
    Any others. Many have suggested that it may be due to a damaged keyboard cable but I think it would be highly unlikely that they would both break in the same way.
    Thanks in advance

    Connect an external USB keyboard and check if the button would work.
    If the button can be used with external keyboard then the internal keyboard is faulty and needs to be replaced.
