  • How to increase the amount of steps of brightness adjustment-key

    - by Koen
    The screen of my laptop (Dell Vostro 3460) supports 16 levels of brightness: Not only according to the manufacturer, but also as is clear from two OSs: Both Windows 7 and Ubuntu (dual-booted) support all levels. On Windows 7, the hotkeys for brightness adjustment support all levels. In ubuntu it is apparent when going on the brightness slidebar (see picture below) from left to right; I can count 16 different levels of brightness when doing so. When using the hotkeys (Fn+F4 and Fn+F4), however, only 5 levels are supported. How can I adjust these levels and make them in line with what my screen supports?

  • How do Unity 12.04/Compiz bindings really work?

    - by Daniel
    There is a bewildering array of places to set bindings, all inconsistent with one another. E.g. in Unity's System Settings having the Ctrl-key highlight the mouse position is an on/off choice. I like the feature, but not on such a prominent key where I keep activating it accidentally. The keyboard shortcuts allow only one binding per command, where I might like a convenient one on the external keyboard and an emergency alternative for when I'm on the road. Keyboard custom shortcuts has a nice interface, but allows only key bindings — besides it doesn't seem to work for me. So I activated CCSM Commands. There I have the choice of key-, mouse- and/or edge bindings. Whereas some places in CCSM offers only one or two of these binding possibilities, randomly at the whim of the programmer. I have not found a way to differentiate a mouse-drag from a click. E.g. I want <SuperMouse1-drag anywhere on a window to move it, while if I don't drag, it should be raise-lower. On the title bar I want the same without needing the <Super key. Now I find raise-lower only in System Settings where I can't assign a mouse binding. If therefore in CCSM I fallback to only lower and put move on the same binding, the window already gets lowered on mouse down, and I can then invisibly move it. Very useful! I have <Altasciicircum get in the way of an Emacs binding, with some to me useless popup overlay. I can find it nowhere, so I can't turn it off. So how can I go without these frontends until they have matured, and instruct Compiz directly, for example in the way Emacs or Sawfish have keymaps, and separate ones for each context, with inheritance?

  • How do I disable the sleep button on my keyboard?

    - by KillianDS
    I have a "power button" on my keyboard that enables standby or hibernate. I can't find the mapping of this key anywhere in "sytem settingsKeyboard", "systempower management", "compiz config or similar (where I could find it before unity). How can I disable (not remap) this button? I do not want to disable hibernate/sleep altogether, it's simply this key that gets pressed a lot by accident and it's getting quite annoying.

  • "Wireless disabled by hardware switch" after suspend and other hardware buttons ineffective - how can I solve this?

    - by fahadayaz
    I have recently purchased a Novatech nFinity N1410 laptop and am having problems with the wireless, which sudo lshw -C network tells me is Centrino Wireless-N 2230 and using the iwlwifi driver. The problem is that after the device has been suspended, I am not able to get the wireless working again without a restart. The network indicator states that the wireless disabled by hardware switch. Though Fn+F2 is meant to be the wireless switch, xev tells me that the system doesn't see it as anything at all when I press this hardware combination. Also, though the brightness up/down buttons work fine, the volume up/down buttons do not work either. What can I do to fix this? I am running Ubuntu 12.10 with all available updates installed.

    - by RealityDysfunction
    Fellow programmers, I have been learning C# for a while now, but my ultimate goal is to develop ASP.NET applications. A few ASP.NET books I looked at either start with absolute basics...What is C#? What is a function...or Assume that I have developed web apps in other languages like PHP...I am looking for a book that is tailored for people who already know desktop programming but wish to learn ASP.NET. Did anybody come across such a book? Many Thanks.

  • Photoshop alternative with same keyboard shorcuts

    - by user292254
    tldr; Is there a program with the same keyboard shortcuts and/or user interface as PS. I know the "photoshop alternative" question has been asked so many times, but I feel this variant is worth the time to ask. I am a web designer and have been using PS daily on a windows or mac machine for about 10 years, but I do most of my development in linux. The only thing that has been keeping me from the full switch to linux is PS. I have tried many alternatives, including GIMP, but I feel the barrier to entry is too high for one reason and one reason only, the keyboard shortcuts. Over the years I have become very adept and quick in the use of PS because of keyboard shortcuts and muscle memory. I realize that many shortcuts can be customized, but many actions are just too different from PS. So my question is what programs are out there that are the closest to PS in keyboard shortcuts and interface. I don't care if I have to do a bunch of customization to get it as close as possible, but I just can't take too much time to learn a completely new workflow. Of course I realize that any software will take time and effort, I just want to make that time/effort as minimal as possible. Thanks in advance for your responses. edit I should tell you the most important features and workflow I use on a daily basis are, Smart objects, linked documents, save for web and devises.

  • Unity bar only shown in Desktop - Alt+Tab doesn't show anything

    - by Christian Vielma
    I've experienced something weird with Unity and that is that sometimes the Alt+Tab switcher stops showing (yes, only showing because I can still to blind switch between applications), and the left unity bar is only shown on the desktop. I might think that it's compiz, but the rest of the effects are ok :S I don't have the exact sequence to repeat this error, it seems to be random :S Do you know what could it be?

  • How do you assign commands to keys in Terminal?

    - by NES
    Is there a solution to assign special key combinations to words in terminal use. For example the less command is very usefull and i use i a lot to pipe the output of another process through it. The idea would be to set up special key combinations that are only active in terminal use assigned to write different commands? So pressing CTRL + l in terminal window could write | less or CTRL + G could stand for | grep Note: i just mean adding the letters to commandline not execute the finally. A similar way what's tabcompletion but more specific.

  • How can I use my keyboard as a mouse?

    - by Michael Durrant
    I'm using my keyboard more and more these days for basic command line stuff, vim editing, alt-tab window switching and the like. Q) How can I use my number pad keys to move the cursor around on the screen without using the mouse? I looked to try and install btnx as mentioned by others but it doesn't seem to exist anymore as an available package I also tried shift-numlock as mentioned by another but that didn't work either (just turns numlock on/off).

  • Why do the Escape and Enter keys not always do the right thing in dialog boxes?

    - by Michael Goldshteyn
    Why is it that when a dialog pops up, the Escape key doesn't always cancel it and the Enter key doesn't always press the default button? Shouldn't this be a standard across all dialog boxes in all applications? I have gotten into the habit of pressing Escape to cancel a dialog and Enter to confirm it, but applications (and especially KDE, GNOME and Unity in many many cases) seem to ignore my wishes. What is the problem? Is consitency too much to ask?

  • New to emacs -- my key bindings are different from what is described in the tutorials. How to fix this?

    - by MountainX
    I'm using emacs v24 [GNU Emacs 24.0.94.1 (x86_64-pc-linux-gnu, GTK+ Version 3.3.20) of 2012-03-26 on meitnerium, modified by Debian] on Kubuntu 12.04. My basic problem is that emacs is not behaving the same as the tutorials I'm reading. I either need different tutorials or I need to make my emacs work as described in the tutorials. Being new to emacs and KDE, I don't know where to start because of this incongruence. My specific problem is this: When I shift-left-mouse-click, I get a buffer dialog popup. That differs from my understanding of the documenation: shift mouse-1 Draws lines, rectangles or poly-lines, erases, cuts, copies or pastes. I also want to use CUA mode. The CUA mode documents seem to indicate that shift-left-mouse-click produces: rectangle highlighting by dragging the mouse while holding down the shift key. I don't get that result either. In fact, I can't select using any modifier keys together with a drag action. Maybe this is a KDE issue. I don't know.

  • Run Virtualbox at boot without a Desktop Enviroment

    - by BiggJJ
    I am wondering if there is a way to run virtualbox XP machine on a Ubuntu base system with no/very minimal Ubuntu Desktop Environment. I want to use Ubuntu for as the base operation system for such things as Samba, DNS, LAMP. But some of the the applications we have developed and use are windows only. And require a bit more "juice" than Ubuntu But we also need the Windows GUI to make changes, etc. I would like this on one machine, rather than a two.

  • Non persistent keyboard shortcuts in Unity

    - by nblumoe
    I did change the keyboard shortcuts for window navigation in Unity to use hjkl (vim movement). I did reassign the shortcuts via GUI in System Settings Keyboard Shortcuts. Here are two examples of the assigned shortcuts: Move window one workspace to the left = Shift+Ctrl+Alt+H Switch to workspace left = Ctrl+Alt+H Occasionally, when restarting the maching, these shortcuts are being reset to theit default values: Move window one workspace to the left = Shift+Ctrl+Alt+Left Switch to workspace left = Ctrl+Alt+Left How can I make these changes permanent? Can someone help me, narrowing down the problem?

  • Disable “Alt+`”

    - by Albert Francis Lavietta
    How do I disable the keyboard combination of ALT+`. This is NOT the HUD nor in the Ubuntu System Settings. It is NOT in compiz configuration either. (I am NOT trying to disable the HUD's use of the Alt key*) When you press ALT+` on a default unity ubuntu 12.04 install it behaves the same as ALT + TAB. I would like to disable this, because my Windows 7 VM Uses ALT+` to switch languages such as korean or chinese.

  • How do I "alt-tab" between windows using Gnome 3?

    - by josmh
    All of the references I've found for Gnome 3 keyboard shortcuts list that alt+tab switches between applications and alt+` switches between windows (some actually say alt+~, but I think they're mistaken, and I've tried both anyway). Maybe that functionality works for Gnome 3 on Fedora or something, because no matter the key combo I try, nothing will switch between windows except for opening the alt+tab dialog and using arrow keys to navigate it (and at that point it's faster to just use a mouse..). How do I quickly switch between windows in Gnome 3?

  • How can I add missing Fn-key controls?

    - by Alex Ball
    I have a Toshiba NB200 netbook. The majority of the Fn-key controls come through fine and are recognized by my OS (I'm running Kubuntu 12.04/KDE 4.9) but according to the markings on my keyboard there are a few more that xev isn't detecting, i.e. Fn + F9 (touchpad toggle) Fn + 1 (increase screen resolution) Fn + 2 (decrease screen resolution) Fn + Space (zoom) Now, I don't particularly need those last three but I thought it would be quite useful to remap them to, say, Media Previous, Media Next, and Media Play, but I can't do that if the signals aren't getting through. Is there any way for me to persuade the OS to recognize these keystrokes? I've tried using acpi_listen to detect scancodes but it doesn't pick up any of function-related Fn-key strokes (like Audio Mute, which does work by the way).

  • Trouble with Ubuntu 12.10 install/evaluation

    - by Mike H
    I am trying to install Ubuntu 12.10 onto my Compaq Presario SR1215CL. I downloaded ubuntu-12.10-desktop-i386.iso file using BitTorrent and burned it to a blank DVD-RW. When I boot the computer with the Live Disk in the disk tray I am able to get to the Welcome screen. If I click on "Try Ubuntu" I am left at a blank screen except for the desktop background. There are no menus, toolbars, icons, etc. If I press Ctrl+Alt+Delete at this stage I am able to log out of the Live Session, but am unable to log back in. If I click on "Install Ubuntu" instead, I am able to proceed fairly far into the installation process, but eventually it quits and drops me to the same blank screen as above. I'm not sure at which stage the installer quits, but it does ask me to identify the issue and solve the problem myself from inside the Live Session, which doesn't work. Does anyone have some suggestions on how to get Ubuntu installed and working?

  • How can I define custom keyboard mappings to resize, move, and manage windows?

    - by fumon
    I just returned to ubuntu (13.04) after a year using OS X exclusively. I love the improvements that have come to ubuntu and unity, and I'm glad to be back. There's just one thing, though... Slate is a simple OS X tool that allows users to quickly create powerful keyboard macros and really take advantage of their screen space. I have to say I was spoiled by it. Even on a tiny laptop, my workflow was never interrupted by changing workspaces or leaving the keyboard to adjust a window, because perfect adjustment was a keystroke or two away. For example: bind h:ctrl;alt;cmd resize -10% +0 # this increases the window's left width by 10% bind h:shift;alt nudge -10% +0 # this moves the window left by 10% You make a big config file, and like vim, tmux, and everything else, it just becomes muscle memory. I can't seem to find a way to achieve anything close to this in linux or ubuntu. I've tried to make do with compiz window settings and the built-in stuff Ubuntu offers, but it's not even in the same realm. Although to be fair, this level of tuning isn't something most people care about. Thanks, guys. :) Any feedback would be appreciated.

  • Ubuntu worldtime desktop clock widget?

    - by ubuntico
    I am aware that in Unity we can add world time by clicking on time bar. However, it's still a list of locations and sometimes it may be hard to quickly find the timezone of interest. Is there any tool which can put a multiple clock instances on the desktop representing each timezone of interest? Similar to the clock in Windows 7. To be more clear, I am not looking for a weather widget, but a simple clock widget so that I can track time in different timezones.
