Programming :: Multimedia Keys On Laptop - Special Control
Jan 14, 2011
I would like to use my multimedia keys on the laptop.
As I have seen in kde, they are recognized already, very good.
But I would like to use the play-pause, ffd, rwd and stop button in a special way.
After pressing one of them , a programm or script is called, which does:
a) determine the entries ( in a list ) of assigned applications to be controlles by this mm-buttons. ( The list can be edited, I decide to add vlc, amarok, flash plugin for firefox )
b) determine, which of the applications are running actually.
c) determine, which of this applications has the focus ( means, which of them ( if all more running ) is "the active one".
d) issue its shell command, which corresponds to the keyhit ( play, pause, fwd, rwd, stop )
Now my question : Is it all possible via shell/and or x-script?
If not, i will have to code something, i suppose.

Right now, it controls both Master and PCM, resulting in weird volume increments. I want PCM to stay at 50 and only change Master with my volume keys.

I have a Dell 1525 and I just installed Ubuntu on it. The Multimedia keys (previous, stop, play/pause, next) and volume control keys (mute, increase, decrease) buttons aren't working at all. Is there anyway I can get them to work?

I am running Arch Linux with KDE 4.5. I have a Microsoft Wireless Keyboard 3000 v2.0
At the top of the keyboard are 5 extra buttons numbered 1 to 5. These are in addition to the function keys.
I ran xev to determine the keycodes generated by these buttons and nothing results. The keys do nothing in xev. How can I enable these keys to use for desktop switching?

I'm installing Slackware 13.1 on a Samsung N150 netbook and am stuck trying to make the special keys do their normal functions when using a virtual terminal, that is not under X. Under X + Xfce it can be done via Menu->Settings->Keyboard->"Application Shortcuts".
In essence the question is how to make a special key (example Fn+Up to increase screen brightness) run a command in the background.
Changed title and text to make clear that the command should not run in a virtual terminal but while the display is being used for a virtual terminal, that is after Ctrl+Alt+F2 for example.

I've been making some progress with my new Dell Inspiron n5110 and the OpenSUSE 11.4. After searching through the net I found some drivers to get my laptop going. Now I'm facing the following problem: I want to adjust the audio volume using a special key combination on my laptop(fn+F11 to rise, fn+F12 to lower, and another key that works as mute). Although the sound itself works fine, when I use these keys the have no effect on the volume. It stays exactly the same. Some I ask myself are the drivers for the sound card installed? In "Playback Devices" there are two devices: Internal audio analog stereo(which is the one that is working) and GF108 High Definition Audio Controller Digital Stereo(HDMI). The lsusb provides:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 003: ID 8086:0189 Intel Corp.
Bus 001 Device 004: ID 1bcf:2880 Sunplus Innovation Technology Inc.
Bus 002 Device 003: ID 0bda:0138 Realtek Semiconductor Corp.
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
So I searched for some Realtek drivers and came up with nothing. If you have any idea on how to get my audio running or how to make the special keys working, please let me know!

how to set at least my headphone/lineout socket precisely to -15dB at boot up? If I knew how to make amixer commands permanent, I wouldn't be re-raising the issue
The Gnome GUI volume control is fine in normal circumstances but to set it accurately requires a bit too much fiddling, IMO - now if someone were to adjust the programming so a dB readout accompanies slider movement, rather than as a pop-up after adjusting the slider, 'twould be more ergonomic, IMO.

Volume up, volume down and mute keys on the keyboard don't control the volume any longer.They worked before. Hitting the keys brings up a progress bar widget with the volume level unchangeable, set at 0% (which is not accurate at all).It looks like the key mappings or key bindings are working, but there is a disconnect with actual functionality. The volume cannot be changed or muted anymore from the keyboard.
This worked just fine in KDE on Fedora 11 before upgrading KDE components yesterday with Yumex. I am now using KDE 4.3.2 I don't think that it's a coincidence that it stopped working after doing an update.
I updated the kernel and nVidia drivers too, but this problem exists when I went back and tested with the previous kernel, so I don't suspect the kernel upgrade. No info in Xorg.conf about the keyboard. Is there a setting that I am missing?
Sound works just fine. I can listen to whatever source I like. This is not a problem with the sound drivers as far as I can tell.I just want to be able to control the volume with the keys on my Logitech Illuminated Keyboard, model Y-UY95. Is anyone else experiencing this?I can adjust the volume with Kmix 3.5 or GNOME Volume Control V2.1

I've got my xubuntu 10.10 install just about perfect on a little acer aspire d250, apart from a small sound useability issue: In the interests of simplicity and resource usage I removed pulseaudio. After a bit of fiddling I got it so that my USB soundcard (ProDac) is recognized and automatically set as the default soundcard when plugged in. Any sound applications automatically use the USB sound if it present, no need to around with pulse. The only problem is that my netbook's volume control keys still only control the master volume of the inbuilt soundcard, and have no effect on the usb sound. Does anyone know of a way to change which sound device these keys actually effect? I'd like to write a little script so that when the usb device is detected the keys are remapped.

I am using Samsung N150 and ubuntu 10.10 is installed in it. There is problem with brightness control i.e., I cannot control my brightness by up & down keys. I made settings such as:
I Add the repository to the sources list and enable it
sudo add-apt-repository ppa:voria/ppa
Perform complete system update
sudo apt-get update && sudo apt-get upgrade
it may take long time depending the internet connection
than I installed packages "samsung-backlight" and "easy-slow-down-manager"
sudo apt-get install samsung-backlight easy-slow-down-manager
Also I made changes in brightness setting in during the boot i.e set to user control instead of automatic. But after doing all these stuff still my laptop brightness not control by fn + up/down keys.

control keys aren't working most of the time in Open Office. I can copy, cut and paste with the mouse, but Control+C/X/V/Z is not working at all. I also use intellij idea, there I have the same problem, but I can use its own defined control+alt+space. I've tried Abiword, the control keys worked at the begging but then after a while when I used control+something(C/X/V/Z), it always selected everything. Besides that, the control keys are working perfectly in nautilus, terminal, firefox, chrome, gedit. I'm using Ubuntu 9.10.

I installed Keytouch in a useless attempt to allow me to brighten my screen (but that's another thread...) and now the control keys don't work. I tried a couple of files that were supposed to be my keyboard, but neither worked. I don't want to mess with it any more, but I can't figure out how to uninstall it!

I don't care if this is done in the bios or a kernel module or software. Is there any way at all to do make the 'fn' key act as 'control' and the 'control' key act as 'fn' in linux running on a macbook pro?
PS. You can do this with software in OSX with the application KeyRemap4MacBook.

I have a problem with keyboard mappings on F13. I have the following in my .xmodmap file that is run from .bash_profile:
[code]...
The problem is that at seemingly random times the roles of the caps lock and control keys (and the other customisations) gets reverted back to normal - which makes for an awful lot of confusion! Running xmodmap again switches them to how I like it, but again after a seemingly random period it resets itself. This occurs under KDE and Gnome in F13, but did not occur in F12. Using the KDE keyboard settings dialog to switch caps lock and control does the exhibits the same behaviour.

I am having a lot of problems with hitting the arrow keys while typing. At least, I think that's what it is. Maybe the page up/down/back buttons, too. Is there a way to disable one or more keys on the keyboard via software, other than going into BIOS? It's getting annoying having to retype stuff over and over. I guess maybe I'm just not used to my new keyboard, is all. But I never use those buttons and likely never will.

I have installed Xubuntu 11.04 on a HP Probook 4510S and the FN Keys of brightness only works when I on the login screen (gdm). Until I enter to my desktop the FN Keys stop Working. This is a XFCE Issue? I have another Laptop, a IBM THinkpad X40, with the same Xubuntu 11.04 and the FN Keys works perfect! Even the keyboard light Works! I think this is a ACPI related problem, I google it the problem with out a specific issue like this. The only thing that I can do it is use of xbacklight when I'm on my session.

I have played around a bit with the Open Shot Video Editor and just download Kdenlive. I am trying to teach myself how to create and edit videos by inserting music, transitions, etc. However, I want to add special effects such as fireworks, explosions, get text to light up, blur, etc, and add sparkle type effects. I know Open Shot won't do this and it does not look likve Kdenlive will either. Trying to find something that will jazz my videos and almost give them a semi professional quality to them. Is there any other Open Source video editor type program that can do special effects like what I am looking for?
