• Fixing Two keys events on single key press by xmodmap

  - by William.Ebe

  I'm using Dell Latitude D620. Whenever, I'm pressing the space key, the down arrow key also triggered perform it's action. Here is the log: KeyPress event, serial 30, synthetic NO, window 0x3200001, root 0x10c, subw 0x0, time 2248017, (70,-9), root:(76,39), state 0x0, keycode 116 (keysym 0xff54, Down), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyPress event, serial 31, synthetic NO, window 0x3200001, root 0x10c, subw 0x0, time 2248018, (70,-9), root:(76,39), state 0x0, keycode 65 (keysym 0x20, space), same_screen YES, XLookupString gives 1 bytes: (20) " " XmbLookupString gives 1 bytes: (20) " " XFilterEvent returns: False KeyRelease event, serial 33, synthetic NO, window 0x3200001, root 0x10c, subw 0x0, time 2248083, (70,-9), root:(76,39), state 0x0, keycode 65 (keysym 0x20, space), same_screen YES, XLookupString gives 1 bytes: (20) " " XFilterEvent returns: False KeyRelease event, serial 33, synthetic NO, window 0x3200001, root 0x10c, subw 0x0, time 2248085, (70,-9), root:(76,39), state 0x0, keycode 116 (keysym 0xff54, Down), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False ClientMessage event, serial 33, synthetic YES, window 0x3200001, message_type 0x157 (WM_PROTOCOLS), format 32, message 0x155 (WM_DELETE_WINDOW) The above log is for a single press+release of spacebar key. I would like to know how to fix that. Thanks. PS: I'm using the same laptop to post question. If somebody helps to align it into code format, it would be helpful as I can't do that with this keyboard properly.

• Chrome in the launcher does not open with keyboard hotkey (Super + #)

  - by Jin

  I'm running Ubuntu 14.04 LTS and I have chrome as the first application locked in my launcher. When I click it or press Super+1 the Chrome icon just flashes, but never opens the app. All other apps open fine. I have to manually find it in Unity and launch it from there, or from Terminal. I've set this to launch properly on another machine but I don't know why it's not working on my laptop. Why does this happen?

• Map function+backspace to delete

  - by Espressofa

  I'm used to Apple laptops, on which Function + Backspace is mapped to Delete. I'm also okay with Shift + Backspace. Is there a way to obtain this? Note, I'm using Xmonad and have some keyboard modifications set up with xmodmap but have very little understanding of how it works. I've tried xmodmap -e "keycode 22 = BackSpace KP_Delete BackSpace BackSpace", which works in some applications but is ignored by my terminal. I've seen this question but it seems KDE-specific. I would prefer not to have to use some GUI.

• emacs keybindings in ubuntu 12.04

  - by sam

  I am trying to get emacs-like keybindings in gtk, firefox, chrome, etc. I have followed the directions recommended here (and in lots of places) but to no effect: http://kb.mozillazine.org/Emacs_Keybindings_(Firefox) In other words, I added 'gtk-key-theme-name = "Emacs"' to my .gtkrc-2.0, and I also ran gconf-editor and set "/desktop/gnome/interface/gtk_key_theme" to "Emacs". I even rebooted just for good measure. I am using an ordinary Ubuntu 12.04 install, with unity3d as the desktop environment. Thanks! Sam

• Custom keybindings without gnome-settings-daemon

  - by Carlito

  I am using Ubuntu 12.04 (Fallback) and I am trying to slim it down, mostly for fun/learning experience. I killed gnome-settings-daemon because I set up my theming from elsewhere. But now some of my keybindings are lost. I think the windowmanager ones are still working, like Alt-Tab and switch workspace. But my mediakeys to change volume and my custom keybindings are not working anymore. Is there a different way to save custom keybindings? Do I really need to run settings-manager to setup my keybindings?

• alt+tab moves windows between workspaces and crashes unity

  - by Ruslanchik

  I have recently been using multiple workspaces in unity but have run into a bug that is making it very difficult to do this effectively. The problem is with alt+tab. When I am focused on a window that is not in the primary (top-left) workspace one of two things happens: Unity restarts (the launcher and menu bar disappear and screen flashes blank before everything reappears) and all of my windows are moved to different workspaces. The focused window is always moved to the primary workspace and other windows are typically moved one workspace to the left. alt+tab will usually function normally after this. Unity completely crashes. The windows in the current workspace are still there, but the launcher and menu bar are gone, I cannot switch between workspaces, and none of the hotkeys work. The same issues occur when using alt+` as well. I have installed ccsm, but have made only minor adjustments with it. I am still using the Unity switcher. I actually uninstalled ccsm hoping that would resolve the issue, but the issue persists. Is there some resolution to this issue? I like Unity and want to keep using it, but having to use the mouse to switch between programs is irritating and enough reason to switch to Gnome.

• Two Simple Keys to SEO Success - Take Care of the Basics and Forget About Algorithm-Chasing

  Search engine optimization (SEO) is critical to the success of any website because it helps to improve a website's visibility in the natural search results - the end result of which should be that the optimized website experiences a sustainable boost in search referral traffic. And yet in spite of the obvious importance of SEO, the reality is that the vast majority of websites have never been exposed to even a bare-minimum level of SEO effort, meaning that they are potentially forfeiting top rankings - and the traffic that top rankings virtually guarantee - to their competitors Why do so few people bother with SEO when it is so essential to a website's success?

• "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.

• Disable/remove Cinnamon keyboard shortcurts

  - by Robin

  I installed Cinnamon on Ubuntu 12.04 using sudo add-apt-repository ppa:gwendal-lebihan-dev/cinnamon-stable sudo apt-get update sudo apt-get install cinnamon Now I am looking for a way to disable the keyboard shortcuts ALTF7 (move window) and ALTF8 (resize windows). I already disabled those key bindings under Keyboard - Shortcuts. This has no effect. I did not find them in gconf-editor under apps -> muffin . Does anybody know how to remove/edit/disable those key bindings ?

• Is it possible to use mac trackpad gestures on a linux virtualbox? (macbook pro)

  - by David

  Specifically, I would just love to use the trackpad to do "three finger swipes" and switch between workspaces, that would just be slick as hell. I imagine this might require a plugin or some such thing, in addition to the disabling of the underlying mac os's responding to the gestures, which is what it currently does. This might be impossible. PS/FYI: I am running ubuntu, but I imagine this might apply to debian builds as well.

• 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?

• 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.

• 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?

• 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.

• Working with Primary Keys and Generators - Quickstart with NHibernate (Part 4)

  - by BobPalmer

  In this NHibernate tutorial, I'll be digging into the ID tag and Generator classes.  I had originally planned on finishing up a series on relationships (parent/child, etc.) but felt this would be an interesting topic for folks, and I also wanted to start integrating some of the current NHibernate reference. Since this article also includes some reference sections (and since I have not had a chance to check for every possible parameter value), I used the current reference as a baseline, and would welcome any feedback or technical updates that I can incorporate. You can find the entire article up on Google Docs at this link: http://docs.google.com/Doc?id=dg3z7qxv_24f3ch2rf7 As always, feedback, suggestions, and technical corrections are greatly appreciated! Enjoy! - Bob

• How to use multiple search keys?

  - by user32565

  I have a database wherein the files are named abcd100.00b, abcd101.00b, etc. I need a code where when the user enters abcd separate then 100 to 110, all the files with the name abcd and in the range 100 to 110 should get displayed now the following code can display only the first four characters. How do I implement this? <?php //capture search term and remove spaces at its both ends if the is any $searchTerm = trim($_GET['keyname']) ; //check whether the name parsed is empty if($searchTerm == "rinex_file") { echo "Enter name you are searching for."; exit(); } if($searchTerm == "rinex_file") { echo "Enter name you are searching for."; exit(); } //database connection info $host = "localhost"; //server $db = "rinex"; //database name $user = "m"; //dabases user name $pwd = "c"; //password //connecting to server and creating link to database $link = mysqli_connect($host, $user, $pwd, $db); //MYSQL search statement $query = "SELECT * FROM rinexo WHERE rinex_file LIKE '%$searchTerm%'"; $results = mysqli_query($link, $query) ; /* check whethere there were matching records in the table by counting the number of results returned */ if(mysqli_num_rows($results) >= 1){ echo '<table border="1"> <tr> <th>rinex version</th> <th>program</th> <th>date</th> <th>maker name</th> <th>maker number</th> <th>observer</th> <th>agency</th> <th>position_X_Y_Z</th> </tr>'; while($row = mysqli_fetch_array($results)){ echo '<tr> <td>'.$row['rinex_version'].'</td> <td>'.$row['pgm'].'</td> <td>'.$row['date'].'</td> <td>'.$row['marker_name'].'</td> <td>'.$row['marker_no'].'</td> <td>'.$row['observer'].'</td> <td>'.$row['agency'].'</td> <td>'.$row['position_X_Y_Z'].'</td> </tr>'; } echo '</table>'; }else{ echo "There was no matching record for the name " . $searchTerm; }

• Unity elements sometimes appear while full screen in Virtualbox - how to stop it?

  - by frumbert

  Launcher is great, and it helps me finds stuff. I have the latest release of 12. But when I'm full screen in VirtualBox running another operating system and I hit some key combination I haven't yet figured out, Unity suddenly grabs keyboard focus. It might be alt-tab, it might be left-control x. I have physically pulled both the windows key and FN key off my laptop because they get in the way, so it's probably not the windows key. You don't know the focus has been stolen because the full screen app (VirtualBox) is still full screen and the Unity element is in the background. But you're busy typing into a Unity box, not your foreground application. This is particularly annoying. In my screenshot (taken from a camera, because the built in screen capture program can't capture a screenshot containing the launcher...) the windows VM is the foreground application, but the "Run Command" entry box has come up and is capturing the keyboard: I would like a foreground full screen app to stay that way. Is there a way that I can keep Unity but only have it activate its elements (e.g. pop out with its search box) if I physically click a button, not type some random key combination that foreground applications can get confused about? Otherwise I can do without the launcher or other elements, because doing my actual work is more involved than just launching programs.

• 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).

• 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?

• What X keysym to use for rfkill / flight mode?

  - by Dave E

  On my laptop Fn+F12 toggles flight mode in windows. I'd like the same functionality in Linux and am looking for the appropriate X keysym that will invoke the equivalent of rfkill block all when mapped with xmodmap. I can see there is XF86WLAN and XF86Bluetooth, but they are not what I'm after. I want it to kill/enable all radio devices. I'm not after the script that would do this (see here for example), but wondering if Ubuntu has this functionality already hooked up and if so, what keysym to set up in xmodmap.

• How to change keyboard sleep button to hibernate?

  - by Allu2

  I have a keyboard with a "sleep" button that does indeed make my computer go to sleep. The problem is that Ubuntu can't really handle sleep on my computer, causing it go into a non-responsive mode, having the CPU fan spinning at full speed and it stops receiving any input. Hibernation instead works mainly as it should. I would like to set the sleep key to hibernate, but the keyboard settings' hotkeys tab doesn't have this "sleep" keybinding and though I could make new one with hibernate --force as the command, it would require root rights to run. How can I change the keyboard sleep button action to hibernate?
