General :: Differences Between Two USB Keyboards?
Jun 24, 2011
I have a proprietary device - something like an iPad screen - which has a front panel display with touchscreen buttons that work internally as a USB keyboard. During testing/debugging I want to connect it to another keyboard via the external USB port.Any application which I open on the device by pressing some characters on the touchscreen accepts input codes from either USB keyboard. I want to limit the touchscreen USB keyboard input only to a specific set of apps.Is there a program which can help me detect which USB port or device the code is coming from? Or someway I can map one keyboard to send a different set of codes? The device is using Linux.

If there is a file in the Ubuntu Repository that will drive a Music Keyboard connected to a desktop computer through a joystick connector? If so, what is the name of the best file in the Ubuntu repository? Then, if there is a driver file for the keyboard, are there any additional files that would be good to download to play piano music on that keyboard?

My old Intrepid box got old and senile in the hardware, so I had to take it back round the shed and put her down.I buried her next to her favorite tree in the backyard. So yes, I got this new Mini ITX setup with a dual core Atom processor and 4 gigs of ram for my new computer. I'm going to use it as a media center in my living room. However Atom 1.6 ghz is no screamer so I'd like to build a system using a light weight operating environment to leave more power for running programs and playing my media.
I could install the latest version of Kubuntu again but I thought this time I'd try to get a bit deeper into Linux and educate myself. Could someone clarify the differences between XFree86, Window Manager, and a Desktop Environment (KDE/GNOME/etc)? I know it goes like Hardware -> XServer -> XFree86 -> Window Manager (I read the tutorial on linux.org). But where does KDE or a "Desktop Environment" come in? Is KDE a decked out window manager with its own programs that runs on top of XFree86 or what? Or does it totally replace XFree86?

I took the simple approach and installed the gnome desktop, but I have read about KDE and Xfce and am curious. There may be a lot more that I just haven't heard about yet too. So the question is: Without doing a reinstall and messing up the downloads and settings I have now, how do I try a new desktop like Xfce or Kde? Also, what are the basic differences between the desktops?

What are the differences between shell , console & terminal?
This probably sounds like a stupid question but I'm having a lot of trouble clearly differentiating between a shell (such as Bourne or bash) and the Terminal application in GNOME. I realise that both are completely different but I can't seem to find a clear answer written in text. Could anyone clearly distinguish between both?

Is it correct to say that Windows UAC is conceptually the same as Linux sudo?
Can you point out the differences between the two?

I have come across the use of the term terminal, virtual terminals/consoles, real-text terminals but do not understand what terminal refers to. Does it refer to the screen that is in-front of me whilst I post this question or does it refer to something specific?EDITI came across a similar post at What are the differences between shell , console & terminal? and it seems to be similar to the one I posted although am still confused about the use of the sentence Decades ago, this was a physical device consisting of little more than a monitor and keyboard. What does this device look like and how is different to a monitor?

I am interested in kernel configuration and compilation, so I have executed ltib and menuconfig, but I am not sure to understand what is the difference between Linux Target Image Builder and the Menuconfig tool? Is menuconfig used by or included in ltib? I understand that both tools generate a kernel, But I guess ltib can process "something more"? (packages/target selection? )

I am only using the 128 character set defined in the original ANSI standard. But as a whole how are the files implmeneted differently. I am not concerned with the display, i.e. if a tab is displayed with 6 or 8 characters but the actual internal representation in memory
One differnce I've hear is the use of (Windows) vs. for line termination (Linux).

[code]...
Well, let's suppose the file is very large, say 10 GB of disk space it is consuming. We perform the above steps. Which operations: cp (copying) or mv (moving) will be more efficient and less time consuming? The inode number 1566966 which was pointing to the file in my home directory is now pointing to the same file which is in some other directry, i.e. /tmp/. Isn't the inode value getting modified in some ways to point to the correct location / beginning of the data block on the hard disk? If the the physical location of the data would not change then we would not be able to free up space in our home directory. That means the mv operation is copying the file into some other location. In other words, it is also performing the cp operation first and then deleting the file from its original location, my home directory in the case above. However, when a file is copied it's inode value changes. But the mv operation is retaining the same indoe value. So, how to determine which operation - mv or cp - is more CPU-friendly or more efficient in terms of performance and time taken to perform the action?

Whenever I boot my Fedora 13, I see that the keyboard layout is switched to USA. I switch it back to TR, and it goes until the next reboot.. Then I have USA again..
I tried removing the USA layout altogether, it just comes back at next reboot.

I physically have a Dvorak keyboard (i.e. not using the layout switch). I also occasionally type in Russian, using the software layout switch available in Ubuntu (I'm using Hardy Heron).
I am unable to switch layouts (correctly) unless I am using a QWERTY keyboard. Is there an easy way to tell Ubuntu that I am using a standard Dvorak keyboard and to adjust the layout maps appropriately? If this is unavailable, how can I make my own Russian keyboard layout to correct for this?

As the title says, I'm interested in two (or more) simultaneous keyboards, each with a unique layout. Everything I've researched indicates this should be possible, but I'm unable to get it to work. Regardless of how I set things up, all keyboards consistently operate as if they share the CoreDevice setting in xorg.conf.
In the above config, both keyboards behave as if they're set for the USA layout. Changing the layout in gnome-keyboard-properties affects all of the connected keyboards equally, but has no provision for altering individual devices.

I would like to be able to have two sessions, each with their own monitor and each having their own, assigned input devices, all off of one computer. In other words, two people would be able to use two different keyboards/mice and two different monitors simultaneously using two different sessions. Is this possible, or should I look into a terminal server machine?

I am having a lot of trouble with my computer... tried to upgrade to Ubuntu 11.04 on my computer, but the update crashed and then the keyboards lights just kept blinking. So I thought okay, I will try A fresh install. So I plugged up my old dinosaur and made a new boot cd. When I try to boot it, it shows that it is loading. But then the screen will go crazy, it will be a bunch of mashed boxes with funy colors sort off.can not get any responce out of it. So I try the boot cd in my old computer and everything works great.My computer specsare(custom):Motherboard = msi 785gm-e51 / 760gm-e51Cpu = AMD Phenom 2 duel core, running around 3.7 GHzRam = 2 gigs of ddr3Video card = GT240 galaxy...Geforce 200 series...An old wimpy 80 gig hardrive..Any ideas, I really like Ubuntu and usally have no problem that I can not Google myself out of but this time I can not find what I need.

I use jessie-32bit of kernel 4.1.3 on ASUS EeeBook X205TA.
And I use Japanese Model. There are key 【,|】and【,_】in this model keyboard.

I can Japanese layout, but the two keys is nonreactive.
And I cannot dpkg-reconfiguration keyboard-configuration.

I'm seeking to make permanent a selection in openSUSE-11.4 LXDE between english and Thai keyboards. And I need help here, as I have only succeed partially. After installing Thai via YaST regional settings, I followed the advice in an LXDE forum here LXDE.org Forum - View topic - How to add layouts to keyboard preferences in LXDE? and on the LXDE Panel I righted click on LXPanel->Add/Remove Panel Items->Panel Applets->Add->Keyboard Layout Switcher. Upon a restart of X that gave me a US flag symbol (for US keyboard) in lower right hand corner. No other language selection. I then as a regular user sent the command
Code:
setxkbmap -option grp:switch,grp:alt_shift_toggle,grp_led:scroll us,th
and I then had a choice between Thai and US keyboard which worked well. That unfortunately is only temporary until the next reboot. HOW to make it permanent ? I tried, and I was unable to make that permanent. I tried adding .Xkbmap to /home/user (restarted/tested) and when that failed I tried adding .Xmodmap to /home/user (restarted/tested) and when that failed I tried adding /etc/X11/Xkbmap (restarted/tested) and when that failed I added same line to /etc/X11/Xmodmap (restarted/tested) and that also failed. The line in all cases was
Code:

I also tired editing the /etc/X11/xorg.conf.d/90_keytable.conf file, changing it to
Code:
Section "InputClass"
Identifier "LocalKeyboard"
MatchIsKeyboard "on"
Option "XkbLayout" "us, th"
[code]....
I could create a script with my 1st successful effort (and have that run when LXDE starts up) but surely there is a more elegant way? I am also NOT keen to have this system wide (even thou I tried that system wide (unsuccessfully) at the end) but I would rather only have this for one LXDE user.

Does anyone know of a variant on the Logitech SetPoint software (it allows more functions for Logitech keyboards and mice) for Ubuntu? Would the Windows version work in Wine? I didn't think it would because the app uses Bluetooth, and I don't know if Wine can do that.

Seen as my ATI driver doesn't support Ubuntu 9.10 and neither does LinuxMCE [my two biggest bug bears at the moment] I am considering downgrading to Ubuntu 8.10.
I just wondered if there were any major differences or if I am likely to see any major issues because of things that were fixed or added to 9.10 that weren't available in 8.10.

I've seen in the forums people prefer or dislike Gnome/KDE. I looked around and the differences seem to be cosmetic and not that complicated. Are there any differences "under the hood"? What I mean by this is maybe the way programs behave, user options, etc. or is it all cosmetic?
