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).

I'm running Debian (Squeeze) and I have a toshiba portege m700. It has five buttons on the front just under the screen, which are the only ones accessible when you flip the screen over into tablet mode. One of them is for rotating the screen, and another is for switching to external display. I want to remap the remaining three to control, alt and super so that I can use shortcuts with the stylusThe problem is, when I used showkey to find out the key codes, I found out that each button generates more than one key code:Button 1:
key 126 press >> super_r, although this is distinct from the actual super key (125) key 7 press >> 6 key 7 release key 126 release
I recently put Ubuntu on my HP G series laptop that originally had Windows Vista and ever since some select function keys (i.e. dim/brighten display) and the num lock/num pad won't work. Why is this and can I fix it?
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 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.
I've never seen it before and its entirely possible that I may have done something to my system to cause it. Basically, when I open any new terminal window I have a '$' sign instead of the usual blah@blah etc. Also, the cursor keys don't work
i use a HP Pavilion dv6-3016ax everything works perfectly and i am very happy with ubuntu! If i could get the Brightness keys to work and the microphone i'd be even better. The brightness FN keys change the slider but make no physical difference of the brightness. And the microphone just doesn't work.
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.
SOLVED (for my laptop at least - Acer Aspire 5740)
The trick was to add "acpi_osi=" (without the quotation marks) to the GRUB parameters. Setting the parameter to an empty string means that no OS is reported to the BIOS. By default acpi_osi is set to Windows NT. I had previously tried "acpi_osi=Linux" but it didn't work, apparently it had to be an empty string.The brightness keys work now I think it might work for other models as well if they have core i3 processors.
I use Ubuntu 10.04 32 bits and I have one keyboard Logitech Comfort Wave 450 with some multimedia keys (PLAY/PAUSE, VOLUME UP/DOWN, MUTE,.This multimedia keys works well in Rhythmbox but in Qmmp and Audacious2 doesn't. I explain this: Start my Gnome session. I open Qmmp/Audacious with one playlist charged, I press PLAY/PAUSE in my keyboard, but Qmmp/Audacious doesn't play. Close Qmmp/Audacious. I open again Qmmp/Audacious and now, when I press PLAY/PAUSE, it works! It also works if I open Rhythmbox before to open Qmmp/Audacious.
I have a logitech dinovo wireless keyboard with those extra multimedia keys on it like Volume Up, Volume Down, and Mute. They didn't do anything so I installed KeyTouch. I was able to select my keyboard from the list in KeyTouch, and if everything was working right then at that point all my extra keys would work. But they still didn't do anything. So I went into the Keytouch editor to make my own custom profile. You click add to add a new key and then it asks you to press a key. So I press the key (Mute) and it recognizes it, and then you select what action you want it to do. I did this for Mute, Volume Up and Volume Down. But yet they still don't work!
Now obviously it detects my key presses (keycode) just fine when I added the new key. So it should do the assigned action when I press that key. What I *want* it to do is mute or change the volume of the Headphones. But as I said that wasn't working at all for some reason. So to narrow it down I instead set the Mute key to simply launch firefox. But it still doesn't work. So there is some disconnect... in the keytouch editor it's detecting the key just fine, but afterwards when you press Mute it doesn't do the action it's supposed to.
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?
I wanted to try out Aqualung, and I like the program, but with one big drawback: the media keys at the top of my keyboard don't work with it. Is there something that needs to be done to enable those keys, or is this a bug with the program or my computer?
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.
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.
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?
I would like to use Caps Lock as its own UNIQUE modifier key (not merely replace it with Ctrl). I have figured out how to do this on windows but not yet in Ubuntu. Here is what I'm looking for:
1. When I press "Caps Lock" on its own, it is equivalent to the Escape key (or at least sends the "escape" command). 2. When I press Caps Lock + <new key>, it does other stuff.
I have figured out how to get EITHER ONE of these to work, but not both at the same time. For example, I have figured out how to turn Caps Lock into the unique "Super" modifier using xbindkeys and xmacro (this achieves #2). I have also figured out how to switch the escape and capslocks keys altogether to achieve #1. But I can't figure out how to get both outcomes at the same time!
Predefinations: From here on in, I will refer to the "Windows Key" on the keyboard as the "Super Key" (Linux terminology)
Consider a user's experience in Windows: * UseCaseA: Accessing the start menu --> "Super Key" open the menu. * UseCaseB: Open the "run dialogue" --> "Super Key" + R * UseCaseC: Open win explorer --> "Super Key" + E * etc.
In GNOME/ubuntu however, apparently there is this odd limitation in that the "Super Key" cannot be both a standalone key, and a modifier key. Is it still the case? Currently running Ubuntu 10.04 and 10.10. Apparently in KDE this works, and in Windows it's worked since Windows95. How can we achieve this functionality in Ubuntu/gnome?
Using: Ubuntu Lucid Lynx (Gnome). I have a physical disability which makes pressing the <Ctrl><Alt> key combination very hard, but it would be nice to have that key combination available to me for keyboard shortcuts. I've never got on with 'Sticky Keys' and don't want to use that as a solution, it takes me so long that it is self-defeating as a shortcut key combination. I use a reduced size keyboard, a Cherry ML4100 (image below), which has a 'Fn' key between the left <Ctrl> and <Alt> keys, this 'Fn' key when pressed in conjunction with F1 or F2 will simulate a F11/F12 key press (see image), it also allows the use of a 'num pad' with the u,i,o,p, etc. keys to the right of the centre of the keyboard but which I never use.
In System -> Preferences -> Keyboard Shortcuts I can not currently use the 'Fn' key at all, it is totally ignored, the system just does not recognize it. Eg. If I press <Fn><A> only 'A' is recognized. What I'd like to do is somehow map the 'Fn' key so that when pressed at the same time as <Ctrl> it simulates a <Ctrl><Alt> key press, while still leaving 'Fn' to work as usual generating F11/F12 key presses when F1/F2 is pressed with it. Alternatively if I could set up the 'Fn' key to work as a shortcut with any other key, EG. <Fn><LeftArrow> to switch to the left workspace, and then map F11 and F12 to another key combination - in fact this second solution would be preferable.
However the xev utility, which I had hoped would provide me with a key mapping code for 'Fn', does not even register when 'Fn' is pressed on its own, but when 'Fn' is pressed with F1 it gives what I suppose is the the F11 key code (it is a different code to what is shown when F1 is pressed on its own). I am beginning to suspect that what I am trying to do is not possible. My disability means that using keyboard shortcuts is a really good way of my doing things, much faster than the mouse, so I'd like a lot set up, and I mean far more than most people would ever use, including starting a dozen or so regularly used apps, I'm running out of what I can do with <Ctrl><Shift>, so really need to simulate <Ctrl><Alt> or have the 'Fn' key active when setting my Keyboard Shortcuts, EG. <FN><A>.
This just started happening, but I haven't logged out or rebooted in a while, so I'm not sure what could be causing this. I have setup some keyboard shortcuts to use the Win modifier key (Mod4, Super, whatever). The keyboard shortcuts utility in KDE list it as the Win key so that is how I will refer to it. Some example shortcuts: Win+t starts a terminal, Win+m toggles windows maximize mode. I had these setup and they were working fine on this install that I've had for about a month, but they stopped working today. I can still use Ctrl, Alt, and Shift as modifier keys and they work fine.
I open the keyboard shortcuts utility in KDE Control Center (kcontrol) and start to set a new keyboard shortcut. i.e. I click on the button to "build" a keyboard shortcut. I can press the Win key and it shows that it detects it, but when I press the 't' key, the shortcut is just set as 't' instead of Win+t. I can also push shift+win and that shows in the builder but when I press the 't' key, the shortcut is now set to 'shift+t', so it seems like the Win key is acting funky.

I understand that some of them may work only with Xorg (e.g. toggle screens), but screen and kbd backlight and volume may work at tty too (because I can change this from tty when xorg is down). I know how to do it all from the console, but I want to bind keys with actions.
E.g. I can change kbd backlight with dbus and attach this action to key in my wm config, but it is not what I want. I want to make it global. I don’t understand which layer may provide the functionality for all users. Now only two keys works as I expect: toggle wifi and toggle touchpad. I haven’t set it up, it works out of the box.

I recently install a Debian 8.0 Jessie on a Laptop Dell latitude E6540 with gnome 3.14+3. But the problem is that it doesn't recongnize my multimedia buttons, I tried some methods but I didn't get results.
I removed pulseaudio save for the libs, and now I can't lock down my desktop with ctrl+alt+l anymore. I can still lock the system with the menu (System > Lock Screen), but it's kind of annoying. Removing pulseaudio has cleared up all of my mplayer stutter issues, but I would like to be able to use the keyboard shortcut keys. Here's the command I used to strip out pulseaudio:
I've setup the .ssh/authorized_keys and am able to login with the new "user" using the pub/private key ... I have also added "user" to the sudoers list ... the problem I have now is when I try to execute a sudo command, something simple like:
$ sudo cd /root
it will prompt me for my password, which I enter, but it doesn't work (I am using the private key password I set)Also, ive disabled the users password using
$ passwd -l user
I am trying to harden my system ... the ultimate goal is to use pub/private keys to do logins versus simple password authentication. I've figured out how to set all that up via the authorized_keys file.Additionally I will ultimately prevent server logins through the root account. But before I do that I need sudo to work for a second user (the user which I will be login into the system with all the time).
For this second user I want to prevent regular password logins and force only pub/private key logins, if I don't lock the user via" passwd -l user ... then if i dont use a key, i can still get into the server with a regular password.But more importantly I need to get sudo to work with a pub/private key setup with a user whos had his/her password disabled.
1) I've adjusted /etc/ssh/sshd_config and set PasswordAuthentication no This will prevent ssh password logins (be sure to have a working public/private key setup prior to doing this
2) I've adjusted the sudoers list visudo and added
root ALL=(ALL) ALL dimas ALL=(ALL) NOPASSWD: ALL
3) root is the only user account that will have a password, I am testing with two user accounts "dimas" and "sherry" which do not have a password set (passwords are blank, passwd -d user)
The above essentially prevents everyone from logging into the system with passwords (a public/private key must be setup). Additionally users in the sudoers list have admin abilities. They can also su to different accounts. So basically "dimas" can sudo su sherry, however "dimas can NOT do su sherry. Similarly any user NOT in the sudoers list can NOT do su user or sudo su user.
