Fedora :: F12 - KDE Keyboard - Meta Keys

Jun 26, 2010

After one of latest update I have problem with meta keys (like shift, ctrl and alt) in KDE. When I press one of this keys, it sometimes stays active after release and deactivates only after I press it again. It's annoying especially while I'm writing some code (php or html) and meta keys randomly stays active after release.

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.

Fedora :: Volume Control Keys On Keyboard Don't Control Volume Anymore

Oct 29, 2009

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

Ubuntu :: Control Keys Not Working In Some Programs?

Mar 19, 2010

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.

Red Hat / Fedora :: Uninstalling KeyTouch - Control Keys Not Working

Mar 6, 2011

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!

PS. You can do this with software in OSX with the application KeyRemap4MacBook.

Fedora :: Random Times Roles Of Caps Lock And Control Keys Gets Reverted Back To Normal

Oct 18, 2010

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.

Ubuntu :: Modifier Keys Do Not Work Through VNC

Aug 30, 2010

I've been an ubuntu user for a few years now, I just never joined the forums since I never really had problems with my installations. Today, however, is completely different. I recently converted my server from windows 2k3 to ubuntu server 10.04, and have been setting ssh and VNC so that I can access it remotely. Both x11vnc and ssh are installed and working fine, as I can connect to the server from my Macbook, but here is where it gets weird. When in VNC, none of the modifier keys work(shift, ctrl, alt, super) and caps lock only works half the time. (I have to press it twice to turn it on and twice to turn it off).

Server Specs:
Dell Poweredge 2500
1x Intel Pentium III 1Ghz (coppermine)
1GB RAM

Hardware :: Multimedia Keys Work When They Want?

Dec 29, 2010

I have tried two different keyboards on 3 distros (Xubuntu, LM 10, LM 9) and I run into the same problem.I the volume (+/-) & mute buttons always work upon login and sometime into the session they just stop working. There seems to be no logic what kills it. The audio , mixer and volume applications work fine just the key bindings somehow get broke. Other key bindings have no issue.

Debian Hardware :: Getting Sun Keyboard Keys To Work

Oct 11, 2010

I got Sun Type 5 Unix keyboard which uses mindin-8 connector, attached to a PC through a special adapter which converts it to USB. The keyboard's distinctive features are Control key in the middle row (swapped with Caps Lock which makes it a Unix layout - much more comfortable for the pinky) plus a whole bunch of extra Sun keys, including such useful ones as "Copy", "Paste", and volume control. (Sun Type 5 keyboard has very good feeling to its keys, much better than Type 7 one).Those extra keys work as expected with this adapter in Gnome on OpenIndiana (OpenSolaris previously), but aren't supported out of the box on Debian. Looking around I didn't find any good up to date tutorial how to enable them on Debian or any other Linux. Did anyone try to do it?

Ubuntu :: FN Keys Of Laptop Brightness Does Not Work

Jul 25, 2011

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.

General :: Getting F Keys To Work In Terminal Emulation?

Jan 28, 2010

I'm running Debian (both Sarge and Lenny, on different systems) under Gnome and have a number of thin client workstations that connect to a software application on an AIX server. I'm using gnome-terminal to provide terminal emulation for this software. Unfortunately, the emulation leaves something to be desired, and doesn't catch all of the F keys properly. It seems F1-F4 act as some form of escape key, exiting out of the software back to the command line, when they should be performing different functions in the software. F5 and F6 work as they should in the emulation. Is there a setting I can apply to my gnome-terminal launcher that will make this behave like it I want? The terminal should ideally match the behavior of a Link MC5 terminal (we have some of these old beasts still around, still crunching away), but alas, I don't know how to implement this.

OpenSUSE Install :: Arrow Keys Don't Work In GRUB

May 26, 2010

I bought a fancy new keyboard a couple of weeks ago, a Logitech illuminated one, and it works great in openSuSE 11.2 . . . after it's booted up. It's a dual boot system, however, and today I needed to get into Windows to do some CAD work, and couldn't! That's when I discovered that the arrow keys didn't work in GRUB. It's the particular keyboard, because I can plug the old one in and the problem goes away. Both are USB keyboards. And it must have something to do with loading a keyboard driver of some sort prior to the GRUB screen, because the new keyboard works fine once the bootup is completed. In fact, I've been using it for a couple of weeks now and didn't notice a problem until today.

General :: Ssh Without A Password (setting Up Ssh Keys Doesn't Work)?

Mar 9, 2011

I want to ssh, scp, git fetch, etc. without a password. I saw the previous questions, and closed ones regarding this issue, but the suggestion seems to be to use ssh keys. However, after setting up ssh keys, I am still asked for my password (it's not asking for my private key password; it's asking for my login password). How am I supposed to set this up so that it only uses my private key for authentication?

Ubuntu / Apple :: MacBook Pro 5,1 Backlight Keys Do Not Work

Mar 27, 2010

I am dual-booting Karmic/OS X. I have a MacBook Pro 5,1. When using the keyboard to change the backlight, the graphic in the top left does move to indicate a higher brightness (albeit, it moves extremely slowly).

I, of course, have all the necessary drivers installed.

I have all the packages I needed from the Mactel repository. This has been a problem within Karmic since I've put it on my MBP. There have been several updates from the Mactel repository concerning the Nvidia backlight package (I don't remember exactly what that package is called though). I hope each time that it will fix what is going on, but obviously, it hasn't.

Is there any program that I could use to otherwise change the backlight? When I'm sitting outside it's really difficult to see what's on my screen as it also doesn't automatically respond to the change in environmental brightness by making the screen brighter.
