• sudo does not work in GUI after upgrade to 13.10

  - by Radim

  On 2 completely different machines I have the same problem after upgrading from 13.04 to 13.10: All programs/task requiering sudo permissions (software updater, starting synaptic, installing programs, shutdown) do not start / execute. No gksu (or other) window comes up. Synaptic never shows, software updater pops up with a "you are not allowed to perform this action" message. All programs / task work when started from terminal with sudo, like "sudo synaptics" asks for my password, starts and works as expected. I am in the admin group which is liked in sudoers config (verified with visudo and getent group admin). Some link from GUI to gksu (or similar) is broken. Please help! Radim

• Environment variable blank inside application

  - by Jake

  I have an environment variable that I've set in ~/.profile with the following line: export APPDIR=/path/to/dir When I log in and load up a terminal, I can verify that the variable is set: $ printenv APPDIR /path/to/dir I'm trying to access this variable from within a Qt application: QString appdir = getenv("APPDIR"); QTWARNING("dir: |" + appdir + "|"); The warning window that pops up shows me: dir: || What is going on here? Am I misunderstanding about how environment variables work in Ubuntu? This is with a C++/Qt App on Ubuntu 11.10 x86.

• 12.10 Unity doesn't appear when using Nvidia drivers

  - by Torben Gundtofte-Bruun

  I've just installed 12.10 from scratch. Unity also started okay, but in a poor resolution. I found a setting (I think it was in "software sources") to change the display driver to Nvidia, and then I rebooted. When Ubuntu now starts, it goes to the desktop (I see a file that I saved to the desktop) but there are no other screen elements -- no Unity, no menu bar at the top, no window decoration, nothing. Ctrl-Alt-T and Ctrl-Alt-F2 work as they should, but it's kinda limiting... How can I restore the default driver? I guess I need a way to open those "software sources" settings again - or anything else that could fix it! I hope I don't have to type all this by hand. How can I install a proper Nvidia driver so that I can get up to 1280x1024? My old tricks don't seem to work, but perhaps they might if I solve #1...

• Clicking on active apps on unity launcher stopped working

  - by Tim

  I don't know how it suddenly became this but here's what's happening right now: e.g. I have 2 firefox windows open, so I see 2 small arrows on the left side icon of the unity launcher. Before, when I click on the firefox icon, I see 2 small windows of the firefox so I can choose which one. Now it suddenly stopped working. (super+W still works though). The bug on my system applies to all progams with multiple window instances like nautilus, terminal, etc. Please help, I don't know what to do. I also have cairo dock, compiz, myunity installed in my 12.04. I tried searching online to no avail.

• What happened to my files?

  - by Ivan Broes

  After a successful upgrade from 11.04 to 11.10 a gradual deterioration occurred -- my laptop became unstable with updates -- I corrected the Aspell file, only to have another appear, I sought but I was blocked out. Had an idea, but resolved one that another problem appeared -- going from bad to worse -- I re-installed windows Vista and Ubuntu 11.10 in the original partitions. Window called it Windows Old and I had no problems recovering my files there - Ubuntu decided it is going to make a new Home directory -- . the questions is where did these files go to after re-installation -- are they deleted? If so That's fine duplicates are in Ubuntu 1 by synchronization - I can only download one file at a time!

• Function keys and Hot are switched

  - by Brian

  I recently got a new laptop and installed 12.10 on it. I noticed right away that the "hot keys" on the F keys didn't always do what was pictured and also I noticed that the "hot keys" and the function keys were reversed. e.g. to close a window I have to hit alt-fn-F2 instead of just alt-F2. This is pretty annoying because I've been using the same keyboard shortcuts for years and I don't really want to have to re-learn them. I would also like to switch what the hot keys do, for example the F3 key is pictured as increase screen brightness but it really puts the computer to sleep. I would like to change this back to increase the brightness I looked in keyboard shortcuts settings but these options are not in there. I also downloaded gconf-editor but was unable to find where to change the shortcuts on it. (they weren't at apps \ metacity \ keybinding_commands like others described) any help would be greatly appreciated

• Unity environment way too slow in Ubuntu 13.10

  - by Santiago

  Unity and its apps open too slowly whenever I open one. It takes a while for them to appear completely. Everything works properly when the window is already open. The biggest problem is with the dash: it's SO SLOW when I'm looking for an app although I have removed some lenses. What should I do or what can I do? These issues only occur with Ubuntu 13.04 and 13.10 whereas 12.04 works AMAZNGLY but I have issues when updating a package or installing a new one, that's why I don't opt for that one. Specifications: RAM: 2GB, Processor: Intel® Atom™ CPU N2600 @ 1.60GHz × 4, Graphics card: Gallium 0.4 on llvmpipe (LLVM 3.3, 128 bits)

• Launch Rhythmbox using a Keyboard shorcut

  - by palerdot

  I use Rhythmbox all the time in my Ubuntu. Is it possible to have a custom shortcut like Ctrl+R in Ubuntu, which can launch the Rhythmbox window, even if it is playing in the background ? Since, the emphasis of Linux OS flavors is to use keyboards as much as possible instead of mouse, i thought this functionality might tremendously help me in my Ubuntu environment. The Keyboard shortcuts sections asks for a command; So, I'm not able to figure out how to give a custom keyboard shortcut to a program like Rhythmbox. I'm using 12.04 if that helps. Thanks.

• Event Driven Programming 101

  - by JHarley1

  Good Morning, I previously asked the Q. of how Event Handlers Work (which I got a great answer for). I would now like to understand the basics of how are events are associated with on-screen objects? An explanation of how Events are associated with on Screen Objects: The application registers the Event, the Event Handler and the Component with the GUI Server. When an Event is detected the GUI Server has to link an Event to a Window and then to a Component, it then consults the Event / Component Table to identify which Handler (s) to be executed. I am having problems finding resources/papers that have mention of this process - especially of a Event / Component Table - can anyone clarify?

• Displaying a grid based map using C++ and sdl

  - by user15386

  I am trying to create a roguelike game using c++ and SDL. However, I am having trouble getting it to display the map, which is represented by a 2d array of a tile class. Currently, my code is this: for (int y = 0; y!=MAPHEIGHT; y++) { for (int x = 0; x!=MAPWIDTH 1; x++) { apply_surface( x * TILEWIDTH, y * TILEHEIGHT, mymap[x][y].image, screen ); } } However, running this code causes it to both dither for a while before opening the SDL window, and (usually) tell me there is an access violation. How can I display my map?

Zoom level which sets the zoom level of the camera. And this is the code I have so far. void Zoom(int pointOfInterestX,int pointOfInterstY,int screenWidth, int screenHeight,int zoomLevel) { glTranslatef( (pointOfInterestX/2 - screenWidth/2), (pointOfInterestY/2 - screenHeight/2),0); glScalef(zoomLevel,zoomLevel,zoomLevel); } And I want to do zoom in/out but keep the point of interest in the middle of the screen. but so far all of my attempts have failed and I would like to ask for some help.

• Synaptics touchpad sensitivity. Issue?

  - by Dave

  Just installed 12.04 LTS and I experience some problems with my touchpad. Everytime I tap/double tap the touch the cursor is moving around (not static as should be) (for example if I want to close a window, I click on "x" button from touchpad, the cursor is moving and not always hit the "x" button). Touchpad buttons left click, right click are working well, but tap not. Did u guys experience the same problem? Is there something related to sensitivity? How to fix it? PS: on Ubuntu 11.10 didn't had this issue

After having installed it using alt+f2 and having used gksudo nautilus I have installed MATLAB in the correct folder which is: /usr/local/MATLAB/R2012a Then I inserted the license and the window told "activation complete" or something like that.

• Loading assets in Monogame

  - by Matebu

  I'm creating a MonoGame application on Visual Studio 2012, yet when trying to load a texture I get the following problem: Could not load Menu/btnPlay asset! I have set content directory: Content.RootDirectory = "Assets"; Also the file btnPlay.png has properties set: Build Action: Content and Copy to Output directory: Copy if newer. My constructor and LoadContent functions are totally empty, but have a look yourself: public WizardGame() { Window.Title = "Just another Wizard game"; _graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Assets"; } protected override void LoadContent() { // Create a new SpriteBatch, which can be used to draw textures. _spriteBatch = new SpriteBatch(GraphicsDevice); Texture2D texture = Content.Load<Texture2D>("Menu/btnPlay"); _graphics.IsFullScreen = true; _graphics.ApplyChanges(); } How do I properly load a texture?

• Errors with linux-image-3.8.0-36-generic and GRUB

  - by user285239

  OS: Ubuntu 12.04 LTS Problem 1: When installing anything (or updating) it always ends with this error: Errors were encountered while processing: linux-image-3.8.0-36-generic linux-image-3.8.0-38-generic linux-image-generic-lts-raring linux-generic-lts-raring Problem 2: When installing or updating stuff it opens some grub files and halts execution until I close these grub files. See screenshot below. Grub files + terminal window (screenshot) Pastebin with terminal output while trying to install something I should mention that I don't known if these two errors are related, but it is a fact that every time I try to install something or run an update both of the above errors pop up. I couldn't find anything of interest in the logs I looked at (probably because I don't know what/where to look), but tell me if you need me to upload something. Edit 02 june. This is the output from lsb_release -a kasper@ubuntuRW:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 12.04.4 LTS Release: 12.04 Codename: precise

I ran ubuntu again and used the help install feature. Needless to say the same thing happen again! does ubuntu work on hp touchsmart computers?

• When tracking which elements were clicked e.target.id is sometimes empty [migrated]

  - by Ivan

  I am trying to test the following JavaScript code, which is meant to keep track of the timing of user responses on a multiple choice survey: document.onclick = function(e) { var event = e || window.event; var target = e.target || e.srcElement; //time tracking var ClickTrackDate = new Date; var ClickData = ""; ClickData = target.id + "=" + ClickTrackDate.getUTCHours() + ":" + ClickTrackDate.getUTCMinutes() + ":" + ClickTrackDate.getUTCSeconds() +";"; document.getElementById("txtTest").value += ClickData; alert(target.id); // for testing } Usually target.id equals to the the id of the clicked element, as you would expect, but sometimes target.id is empty, seemingly at random, any ideas?

• Proxy authentication box not showing (sometimes)

  - by zerologiko

  I'm behind a proxy that require authentication by means of user/pass. I'm using Ubuntu 11.04, I think the proxy is "Squid". Usually everything works fine, that means that the browser shows me the window to insert proxy user/pass and I can navigate. The problem: Sometimes the browser refuse to show the authentication windows and if I wait enough it gives me an error like: Errore 130 (net::ERR_PROXY_CONNECTION_FAILED) Even if I restart, disconnect, the situation doesn't change. BUT on Windows the network (and the proxy) works.. So, bottomline what I know is: the network is working (though only on Windows) the Ubuntu configuration is ok (because i can navigate most days) The problems resolves itself in a few hours but I don't understand why. Some hints? Thanks in advance! Andrea

• If my URL's are static, but then parsed by Javascript, does that make it crawlable?

  - by Talasan Nicholson

  Lets say I have a link: <a href="/about/">About Us</a> But in Javascript [or jQuery] catches it and then adds the hash based off of the href attribute: $('a').click(function(e) { e.preventDefault(); // Extremely oversimplified.. window.location.hash = $(this).attr('href'); }); And then we use a hashchange event to do the general 'magic' of Ajax requests. This allows for the actual href to be seen by crawlers, but gives client-side users with JS enabled an ajax-based website. Does this 'help' the general SEO issues that come along with hashtags? I know hashbangs are 'ok', but afaik they aren't reliable?

• where does the discrepancy between \# in PS1 and n in !n come from?

  - by Cbhihe

  Something has been gnawing at me for a while now and I can't seem to find a relevant answer either in man pages or using your 'Don't be evil' search engine. My .bashrc has the following: shopt -s histappend HISTSIZE=100 HISTFILESIZE=0 # 200 previous value Putting HISTFILESIZE to 0 allows me to start with a clean history slate with each new term window. I find it practical in conjunction with using a prompt that contains \#, because when visualizing a previous command before recalling it with !n or !-p, one can just do: $ history | more to see its relevant "n" value In my case, usually the result of: $ \history | tail -1 | awk '{print $1}' # (I know this is an overkill, don't flame me) equals the expanded value of # in PS1 minus 1, which is how I like it to be at all times. But then, sometimes not. At times the expanded value of # sort of "runs away". It's incremented in such a a manner that it becomes than $(( $(\history | tail -1 | awk '{print $1}')+1 )) Any pointers, anyone?

• Really weird situation with Swap that refuses to work

  - by Ghost

  So I decide to move my Swap partition to another HDD to make hibernation more fast, I create a partition with a liveUSB, do swapon, and then hibernate just disappears I go into the terminal, reactivate hibernate (so the button shows) for some reason the swap wasn't "on" so I do swapon again. Still not working. I go back to the terminal and edit the file with the UUID of the new swap partition. The partition shows as swap on gparted, it's on, the file has the right UUID, even the task manager shows a swap area of 10GB, and there is a hibernate button on the shutdown window. But it-wont-hibernate! What's going on?
