• Printing to a printer connected to a wireless router

  - by mspencer

  I have a Netgear WNDR4500 wireless router which allows me to print wirelessly to a printer connected to it via a USB cable. However, the software used to print to it only works for Windows and OS X. I've seen the question Printing to a printer attached to a network USB hub, and tried the instructions it gave using my router's IP address, but when I print a test page it says copying data then says printer is in use. In the printer queue window it says not connected. How can I print to the printer using Ubuntu? Thanks.

• How to Delete/Disable gnome panels. No existing solutions working

  - by Alan Peabody

  I would like to remove gnome panel completely. I spend most of my time in a (tmux) terminal or a browser. Synapse and a small hidden AWN panel fit the rest of my needs. I have tried all recommended solutions including this (found it a few places): How to delete Gnome Panel? However it always comes back at log in. I have tried changing the required components panel to avant-whatever as well as to empty. I have tried setting them both as default (right click set as default). Right now I just have the last panel set to transparent and auto hide, but it still tends to be annoying. What do I need to do to get rid of this damn thing? Clarification: Using gconf-editor, gconftool2, and/or Ubuntu tweak to set /desktop/gnome/session/required_component/panel to avant-window-navigator is not working. The setting stays when I reboot, but the empty gnome panel sticks around.

• Thread problem updating Windows Forms control in XNA C#

  - by Luis

  I'm development a network card game, and for now i've two players connected but there is a problem with one of them, this one can't do anything on the game. Looks that screen was blocked. I'm think that is because a code i used before. That code is: if (InvokeRequired) { this.Invoke(new MethodInvoker(delegate { ... })); return; } The code above is surrounding code to changing Button values, make connection with server and create game window. Without this code a warning is shown. InvalidOperationException was unhandled Cross-thread operation not valid: Control 'startGameButton' accessed from a thread other than the thread it was created on.

• copy & paste in VirtualBox remote console when running headless

  - by katsumii

  One can run VirtualBox guest in "headless" mode and access it using Remote Destkop Protocol(RDP) client.This is typical when VBox server is installed on Linux/Solaris where X-window stuff is not installed and users useWindows to access the VM.So, one can install OS into VBox guests using Remote Desktop client.(e.g. mstsc.exe)Here's the setting. One lesser known feature here is that you can copy&paste into and out-of VM guest and your client.Apparently, "VMware Workstation" still doesn't support it. VMware Workstation Documentation CenterYou cannot copy and paste text between the host system and the guest operating system

• Display in applications on ubuntu 12.10 is broken - maybe theme problem

  - by Aleksandar

  I have a problem which looks like this: http://s16.postimage.org/yjusy9en9/Screenshot_from_2012_10_28_22_49_07.png If you take a look at buttons "Apply", "Reset", "Close" or any other buttons or drop-downs, you will see there is no style on them. It is a fresh install of ubuntu 12.10 and it was working on the beginning. But after some time setting up ubuntu I noticed the style on the elements has gone - I don't know when. I installed compiz-settings - maybe that caused - but when I un-install nothing changes. Also checking/unchecking "window decoration" in compiz doesn't help. Please help me. I am out of options :/

• Why is Google not indexing my forum?

  - by jsoldi

  I have this web site that as you can see on the top right has is a "Forums" button that links to my forums. My problem is that if, for instance, I make a Google search "site:heliumscraper.com answers" I don't get any result, even though the word "answers" is in the forum's board index and it has been there for a few months already. I don't have a robots file. I also uploaded a sitemap to Google that contained the forum. I'm thinking the problem might be the fact that the only link from my main page to the forum opens in a new window. Could this be the problem?

• Switching to Kubuntu results in low graphics mode

  - by HackToHell

  I looked at some screen shots of Kubuntu and I liked it so I went to Synaptic and installed the kubuntu-desktop package and set my desktop window manager to kde and rebooted. After reboot, I saw Kubuntu splash screen then this message; running in Low Graphical Mode. Then I was not able to dismiss the message because my mouse did not work Seemingly How to Geek had the same problem http://www.howtogeek.com/howto/ubuntu/install-kde-kubuntu-on-ubuntu/ . You will probably see that your xorg.conf file was backed up to xorg.conf.1 during the ?KDE / Kubuntu installation. Just copy the xorg.conf.1 back to xorg.conf, reboot, and everything should be fine. I also tried to do that by booting into recovery mode and then droping onto the shell. But it would not let me rename, came up with some error.

• application custom stock icons not working in ubuntu unity top panel menu (aka appmenu) ("Menus Have Icons" ON)

  - by giuspen

  I recently noticed that in ubuntu unity the top menu of my apps does not show the (custom) icons I added to the gtk stock, but only the basic gtk stock icons. This happens only since the top menu is displayed in the unity top panel (appmenu) and not in the application window. In place of the correct custom icons I see "gtk-missing-image". On my apps toolbars and other menus those icons are displayed properly, the problem is only with the top menu. This happens either with pygtk2 (e.g. http://www.giuspen.com/cherrytree/) and gobject introspection (e.g. http://www.giuspen.com/nautilus-pyextensions/). I use gtk ui manager after integrating the stock icons this way: factory = gtk.IconFactory() pixbuf = gtk.gdk.pixbuf_new_from_file(filepath) iconset = gtk.IconSet(pixbuf) factory.add(stock_name, iconset) factory.add_default() If anybody solved this problem please help. Cheers, Giuseppe.

• Run application in specific X server or VNC port

  - by SirCharlo

  I have an application that I'd like to run, yet I'd like it to be visible only through a certain VNC port. I don't want the app to show up on the normal Ubuntu desktop. I want the app to run "in the background", and be viewable through VNC only. And when connected to this "alternate X server", the end-user wouldn't see any menu bars, no window decorations.. Just the app. Come to think of it, what I'm asking for is a sort of kiosk-mode for only a certain app, accessible through VNC. Is this possible or am I really reaching here? Thanks! Note that the app I wish to run in this fashion is written in Java. It is a JNLP file.

• What Extends JComponent?

  - by Geertjan

  Let NetBeans IDE tell you what extends JComponent: Thanks to Damian from Gdansk in Poland who left a comment in this blog yesterday that explains how to achieve the above: "Let's say you would like to find all implementations of TreeModel interface. I found today an answer: r-click on class/interface -> chose Navigate->Inspect Hierarchy->select second filter at the bottom of opened window or press Alt+Shift+F12 and then Alt+B." In the list above, double-click an item to open it in the NetBeans Java editor. Handy tip, dziekuje bardzo, Damian.

• Why is the top menu-bar not accessable when previewing open windows of an application?

  - by coversnail

  If I have more than one window of the same application running then clicking its icon in the launcher displays a preview of that application's open windows, When this preview is activated I can't click on any of the icons in the Ubuntu menu-bar/panel/top bar (although hovering over them does highlight the icons). It seems odd that you can highlight the icons but pressing them has no effect. Is this behaviour normal, a bug, or a slight design flaw? I only noticed because I wanted to shut down when previewing the open windows and couldn't click on the panel power icon.

• BizTalk 2009 - Project Creation Failed

  - by StuartBrierley

  A couple of weeks ago I had some issue with my BizTalk Server 2009 development environment  which resulted in a reinstall of Visual Studio 2008 and the Visual Studio 2008 Service Pack 1. Following this reinstall I began to have problems when trying to create  BizTalk 2009 projects: Error Details: “Create BizTalk Project …. Project Creation Failed” It turns out that this is a known issue with BizTalk Server 2009 and Visual Studio 2008, whereby the installation of the Visual Studio Service Pack 1 can cause corruption to the BizTalk installation preventing the creation of any new projects. To resolve this issue go to control panel > add or remove programs > Microsoft BizTalk Server 2009 and select Change or Remove.  When the window opens choose “Repair”.  Upon completion you should once again be able to create BizTalk projects.

• Override Built-In Maverick Keyboard Shortcuts

  - by jrc03c

  Having used the Command+M keyboard shortcut to minimize windows in OS X, I'd like to use the same functionality in Ubuntu 10.10. When I try, though, it only brings up the "communications" section of the indicator applet; like so: In the Keyboard Shortcuts preferences, I have set as the minimize shortcut Mod4+M, which I got by capturing the Apple Command key and the M key. I find no other shortcut using this key combination in Keyboard Shortcuts, and yet I cannot get the window to minimize when using it. Does anyone know how to override Ubuntu's default usage of this key combination? Thanks!

• Why do I need to relaunch dkpg-reconfigure keyboard-configuration after every startup?

  - by yves Baumes

  I've switched recently to an UK keyboard, from a FR keyboard. It is an usb keyboard, and first I plugged it in, I had to launch dpkg-reconfigure keyboard-configuration in order to request the correct layout (ie: uk). But after every reboot of the machine, the laytout comes back to the FR layout. How can I make the modification persisting? I am using Ubuntu, running the Stump Window Manager. And here is the /etc/default/keyboard at any time (that is right after startup, and before and after I run the dpkg-reconfigure tool) XKBMODEL="hhk" XKBLAYOUT="gb" XKBVARIANT="" XKBOPTIONS="terminate:ctrl_alt_bksp"

• Can't Select Continue to install ubuntu alongside them

  - by msknapp

  I'm trying to install ubuntu 14.04 alongside Window 7 on my PC. I got to the installation type page and it detected my windows 7, then asked me what I would like to do. I selected the option to install ubuntu alongside them; however, the continue button was then grayed out. If instead I chose the option to do something else, the continue button was still grayed out. I was given absolutely no explanation for why it was grayed out. The only option that would let me continue was to erase the disk, which I do not want to do. I have two hard disks, and one of them has two partitions on it. The second partition is completely unused, and has a terabyte of space. That's where I wanted to install it. Can somebody please tell me why I can't install ubuntu alongside Windows 7 here?

• How do I make Nautilus windows stick for drag & drop?

  - by e-satis

  When you drag and drop a folder with nautilus, you must carefully set both windows on non overlapping areas of your screen, otherwise selecting one folder will bring the windows to the front, hiding the second one. On Windows, doing so will stick the explorer.exe windows to the back and let you drag and drop the folder. I suppose it detect a long click to decide whether or not bring the window to the front. Is that possible with Ubuntu? Now I know that Nautilus now has split panels by pressing F3, but that not handy. Most of the time, you open a folder, THEN decide to copy. With split panel, you must decide, THEN split the panel and go to the right folder.

As a work around I: Open another window (usually my browser or mail client); I type the character I need; Select and copy the character onto my clip board; Copy the character into processing. What do I have to do to make processing accept characters under dead keys? Disabling dead keys is not an option.

• Google's Opinion on Javascript Page Refresh

  - by user35306

  I was wondering if anyone knows Google's view on this. My company has a homepage that features a lot of 3rd parties on it and it needs to inform customers which ones are currently online, which aren't, and which are currently busy. Because this constantly changes, we have the homepage refresh to show the most relevant and up-to-date content to our users. I'm not using a meta refresh element in the http-equiv parameter to do this. Instead I have this js element to refresh the page: window.setTimeout("refreshPage()", 120000); I just want to know whether people think Google might consider this a violation of the content guidelines or not. Or if it's not an outright violation, then at least if Google frowns on this or not. It doesn't redirect the user to a different page or anything, just refreshes the page so that they can see the most relevant content.

• KVM switching from lower resolution system resets Ubuntu high resolution

  - by Ed Manet

  I'm running 12.04 desktop on my main desktop and it's hooked to a KVM (IOGear miniview) that shares the peripherals with a SLES 11 machine. The SLES 11 machine can't get the same resolution as the Ubuntu machine because of different graphics hardware. If I switch from Ubuntu to SLES and stay there too long, when I switch back to Ubuntu the screen resolution on Ubuntu is reset to the same as SLES. I can get it back easily just opening the Displays configuration; it immediately resets to the high resolution as soon as the Displays window opens. But all my open windows have been maximized and it's a P.I.T.A. having to resize them all again. How do I get it to just stay at the high resolution between switching between systems? Is there a setting in the Xorg conf file I need to set?

• Keyboard shortcut: Win key doesn't work for custom commands

  - by Xiè Jìléi

  It's all ok before upgraded from 10.04 to 12.04. It seems all right. In keyboard shortcut window, if I pressed Win+V, it can capture the key combination as Super+V, no problem. I've checked the output from xev utility, the left and right Win keys are translated to Super_L and Super_R correctly. I have found a workaround, though. Using gconf-editor, edit the entries /desktop/gnome/keybindings/*/binding and replace <Super> with <Mod4> for the problem bindings. However Super+... keys do work for most built-in actions such as "switch workspace", they just don't work for custom commands.

• Can empathy be configured to stay updated will a full conversation?

  - by kas

  The Google Talk web app and Android app will always update themselves with all messages sent from all clients and I was wondering if Empathy can be configured to do this. For example, if I start a conversation on my phone and then change to my PC an use the web app, all the messages I sent will show up in the IM window on the PC even though I sent them when I was on my phone. Empathy does not behave this way. It only shows the IMs that occurred when using Empathy. If Empathy cannot do this, is there another client that can?
