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.

How can I make terminal applications immune to terminal emulator close, but still able to use all virtual terminal features?
egin{UPDATE}I want my terminal application remain alive and accessible if I accidentally close terminal emulator. This functionality is provided by screen and tmux, but they have issues with colors and they flush screen.Yes,I can run the shell inside screen, but I do not want the shell remain alive unless there is some other program running.
end{UPDATE}I see this must be something like screen, but without VT100 terminal emulation, something which will just apply whatever application does with "terminal proxy"'s terminal (like outputting something to stdout/stderr or using stty to set terminal options) to the terminal this proxy runs in.
// I know about screen and altscreen on, but it makes either this (screen with TERM=screen):
or this (screen with TERM=rxvt-unicode):
while I want this (rxvt-unicode without screen):
I have figured out that everything looks fine if I compile rxvt-unicode with USE=-xterm-color (in fact vim looks like on the second picture even without screen if I add this USE flag) and set TERM=screen-256color, but I do not like this workaround because it actually changes colors and I can't be sure that it will always change them only this way:

I'm on Ubuntu9.10 with pulseaudio setup, everything works fine so far. But when I try to record my Desktop with xvidcap or recordmydesktop I'm unable to get the sound working.
xvidcap uses only OSS so I tried to setup the emulation by loading the kernel modules and adding the following lines to /etc/modules:
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
[Code].....

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 did something stupid; I think while creating some new short+keys for the terminal, I must have enabled an unknown feature to me. The keypad now acts like a mouse. For example; With NumLock on, I press 7 the mouse goes north+west. I press 6 the mouse pointer goes east.

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 am using windows XP as my host machine and vmware workstation 6 to install and run RHEL 5. I have set the inittab to runlevel 5. While i am in gnome, i tried pressing
Ctrl-Alt-F3 and nothing happens. I searched the net and found that i should do this
Ctrl-Alt-Shift-F3. It worked and kinda throwed me to shell mode. When i issued runlevel command it showed me
N 5
Now when i tried to go back to gnome by pressing
Ctrl-Alt-Shift-F5 it didnt work !! i tried all other combinations
Ctrl-Alt-Shift-(F1-F5) but no response.

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.

this may not be the right place to ask this, but my sister has a macbook and the keyboard does not want to work. i have looked online and i see that the main cause of this problem is in Leopard (correct me if im wrong). So i was wondering if perhaps using linux would solve this problem or if the problem is more hardware related than os related.
Also, how would i go about booting into a linux cd? since u need to enter some keyboard keys at startup and assuming that won't work, is there another way?

I don't know if this is a configuration issue or a hardware issue, but I have a Kinesis Advantage USB keyboard and for some reason the F3-F5 keys aren't responding as they used to. They don't respond to anything and, when I tried using F5 on Emacs, it said <XF86AudioNext> is undefined, so I guess it's a weird mapping problem.
Any idea how I could remap them to the original meaning?

Is there an application that allows one to 'export' a drive or virtual disk image to firewire so that the machine at the other end sees the computer as a regular firewire drive? Apple computers can do that via their target disk mode (hold down t on boot), but I am searching for an application that would work under Windows or Linux.The goal is to boot an older Apple iBook, which can not boot from USB, via this emulated firewire drive.

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 am having trouble using home and end keys in a terminal, to go to the end or beginning of a line. With xterm it will only work with the bash shell, while under zsh nothing is output. With urxvt, mrxvt and aterm pressing the keys in either bash or zsh always just results in a tilde being printed. Is this perhaps because urxvt, aterm and mrxvt are emulating a different terminal type to xterm by default?
Why does xterm work for bash but not for zsh? I don't just want a solution, I want to understand why it doesn't work by default. As a side question, is there any way to press alt+enter within a terminal? I tried to use wicd-curses where you have to use alt+enter to save settings, and it didnt register in any of the terminals, even xterm.

How does one switch between command line and keypad modes when using the jed editor with EDT emulation?
OpenVMS User's Manual states that when using the EDT editor if the user wants to control EDT using the keypad, the mode needs to be set for keypad rather than command line input:
I am using:
with this .jedrc file:
Using the -batch shows that the .jedrc file is correctly located.

Im running ubuntu 9.04 remotley via ssh, using putty on a windows computer to control it. I want to redefine one key (I have a swedish keyboard where I have to press AltGr+key to get a tilde sign, would be better if I could get the tilde without AltGr modifier).
I read about xmodmap and xev. Using them I succesfully redefined the key for x-programs. For example if I start firefox over ssh and press the key I get the correct key. But in the terminal session the changes does not take effect. Which is probably logical since xmodmap does only work on the x-server. But how do I redefine the keys for terminal use?

I want to reassign ctrl-shift-C and ctrl-shift-V. How is that done? (I'm using a Mac keyboard and I'd like to take advantage of the command key to avoid having to hit two modifiers.)

I was trying to sign my Ubuntu Conduct Agreement with the key I created for luanchpad. I have one other key that is used for my private folder. While using pgp --clearsign to sign my agreement it kept using the first key I created for my private folder. My work around was to create an email and then copy/paste using the correct key. how can I select between multiple keys from the terminal with pgp --clearsign?

Since the upgrade to Xubuntu 10.10, I'm having issues with Xfce4-terminal. When I use aptitude, the home and end keys don't scroll the list to the top or bottom. With vim, it generates input of adding a new line with F or H on it above the current line. Ctrl+arrow left/right also generate unwanted signals/characters.This does not happen with Kubuntu or Ubuntu and when I install Gnome-terminal and use that, everything works as you expect. This even happens on the live environment. I don't want to use gnome-terminal, as it pulls in more packages than I need and the Xfce4-terminal should just work.
Another thing that happens is that when I read a man page or close vim or aptitude, it behaves as if it's in a TTY: the text it just showed stays on screen or it clears the bunch in the current view and puts the prompt at the bottom. It should be that the application just closes and you get the prompt back the way it was before you started to read the man page for example.It is purely a terminal emulator problem. Does anyone have a solution for these issues?

Ubuntu 10.04 - Gnome Termainal - BASH pressing cursor keys in certain users produces garbage. For example:
pressing up arrow produces: ^[[A
pressing down arrow produces: ^[[B
pressing right arrow produces: ^[[C
pressing left arrow produces: ^[[D
Naturally, I'd like my bash history instead of this. For root and my main user I have no problems. I have a few system users (who don't have a standard home directory) and this seems to occur with those users. For example, my amandabackups user has a home directory of /var/lib/amanda.

I have recently added a new keyboard layout - international U.S with dead keys - so I can type accentes and so in spanish. Ever since that gnome-terminal doesn't recognize the shortcuts keys like <ctrl>r or <ctrl>c and I get my other language charecters instead. thats happen with any keyboard layout I swith to. Furthermore, <alt><ctrl>+F1...F9 doesn't work either.

Is there any way to disable shortcut keys in XFCE Terminal ? I can't seem to bind the shortcut keys, and F1 especially really gets in the way for some programs. Have no clue who thought it would be a good idea to bind F1 to a stupid help screen, when many terminal programs need this. I am using fluxbox, so maybe this has something to do with it.

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

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.

I just love Linux! I am using Fedora 14 and just starting out. I am curious as to why is that when I click the Firefox icon to launch the internet from the menu bar a Linux terminal window has to be open. If I close that particular terminal, (which by the way says "Terminal" and does not show my chosen host name) Firefox closes. If I go to Applications, then Internet, then Firefox to launch the browser, the terminal doesn't open.

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 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.
