• Why is 'libgnomevfs' files under /usr/include/gnome-vfs-2.0?

  - by George Edison

  Most applications, including the gnomevfs headers themselves, expect the files to be under /usr/include/libgnomevfs, but Ubuntu has them under /usr/include/gnome-vfs-2.0/libgnomevfs. Why? The package I'm referring to is called libgnomevfs2. Inside /usr/include/gnome-vfs-2.0/libgnomevfs/gnome-vfs.h` we find: #include <libgnomevfs/gnome-vfs-acl.h> #include <libgnomevfs/gnome-vfs-address.h> #include <libgnomevfs/gnome-vfs-async-ops.h> #include <libgnomevfs/gnome-vfs-cancellation.h> ... Meaning that even the headers themselves expect the files to be in that location - and nothing that includes this file will work. Am I missing something, or is this a glitch?

• What is supposed to happen when you install Gmail webapp?

  - by ubuntico

  I have installed Gmail (and other Google as well) webapps into Ubuntu 14.04 64-bit. After that I rebooted the system hoping that webapps will integrate into the system. But after logging back to the system, I see no changes. If I click on email envelope (top bar), I don't see my inbox. Also if I try to search email in Dash via gmail keyword, nothing happens as well. Am I using this wrongly or webapps don't work? What was supposed to happen when I install webapps? Note: I did start the Gmail app from Dash and logged in

• Detect Open Space in Farseer

  - by Tom G

  I'm working on a 2D platformer using XNA and Farseer. I would like the player's character to be able to grab and climb up ledges. Detecting a collision between the player and the side of a wall is simple enough with the OnCollision delegate, but I have to admit I'm a bit stumped on how to detect that there's enough clearance for the PC to mount the ledge. Essentially, I want to ensure there's an appropriately sized rectangle above and to the left or right of the PC (depending on their direction) and I'm not sure how I would check for such a space. Any suggestions on how to determine there is nothing in the simulated world within some bounding rectangle?

• Is there a way to change the root password while still logged in? I did something bad by accdient -_-

  - by Robert

  So I was trying to add my printer, and I wasn't able to make any changes due to the fact that cups was not accepting my root password. I was Googling some changes and trying to fix the problem when one of the commands CHANGED MY SUDO PASSWORD! Can someone please tell me which one of these is the culprit? I was trying to these commands: cat /etc/group | grep root cat /etc/group | grep myUserName usermod -a -G lpadmin myUserName sudo usermod -a -G lpadmin myUserName sudo gedit /etc/cups/cupsd.conf lppasswd -a myUserName lppasswd -a root sudo lppasswd -a myUserName I think it was this one, but I know which passwords I put in! There was nothing which I typed in besides my strong password or my easy temporary password. Unless I made a typo... please no. restart cups sudo password root This is so not cool, I was just trying to add a printer :'( Please help my stupidity!

• Dog-1 testing as a synonym for integration / system test

  - by SkeetJon

  In the company I'm working for the phrase Dog-1 is used for the software testing scenario where the first piece of data passes through the complete system. Has anyone heard this phrase in a similar context? There's nothing on Google about it in a software development context, so I'm guessing its a idiosyncrasy of my current environment. Is there a recognized phrase in the industry for this kind of test? I don't think it's simply a 'system test' / 'integration test' as 'Dog-1' refers specifically to the first item/unit through the system.

• how to apt-get install with only minimal components necessary for an application

  - by ib84

  apt-get is really great. However, when you want to install an application, you often are forced to install a lot of dependencies which I believe are very often optional. For example, I want to install okular and I'm ask to install 97 packages / 233MB ! That is a lot. I particularly dislike that it wants me to install nepomuk and a lot of other stuff that has nothing to do with PDF viewing per se, and which implies demons, and many of which are clearly optional but not necessary. Question: How to do minimal install with apt-get for a given package, with only the necessary componentents to get the thing run? It's ok if some features disabled at first.

• Disabling IPv6 on a single interface

  - by ijw

  I'm slightly weirded out by the fact that Ubuntu won't process ipv4 DHCP unless you explicitly tell it to, but will happily take ipv6 RAs unless you tell it not to. Is there any way to change the default behaviour to be 'do nothing unless I explicitly turn it on'? (Note to answerers: I'm not looking to globally disable ipv6, or completely turn off autoconf. I'm looking to disable autoconf by default (as in, I don't want ipv6 unless I say so in /etc/network/interfaces, in the same way that I don't just get a v4 address unless I've explicitly turned on dhcp). What's happening is that, for any interface that's up - e.g. has an ipv4 config - a v6 address tends to just turn up on the interface as well, despite the fact that I've not enabled that explicitly. The solutions to date are fine as far as they go, but if I disable v6 or autoconf globally, I can't then re-enable v6 on a per-interface basis with a simple command in /etc/network/interfaces. I'm fairly sure I'm asking for the moon on a stick, mind you.)

• Chrome keeps crashing after updates

  - by Phil

  I'm a chrome user and an enthusiast but few days ago I made Ubuntu get some updates using Update Manager, then I turned off my notebook and when I restarted it, I tried to start Chrome which after a few seconds turned the screen completely black, and some errors appeared for few seconds and then I got logged off, and had to re-login, and when I opened Chrome again the same thing happened! I've uninstalled it with Synaptic and did complete cleanings before re-installing Chrome but nothing succeeded. Now I can't use either Chromium and Chrome, but Firefox works. It's a very strange thing, never happened to me before and I don't know what to do because I had all my bookmarks syncronized in Chrome! Please help if you can :)

• How do I change the "Default" password

  - by Allwar

  hi, here's my problem. When I log in I'm beeing asked for a password connecting to the internet which is strange because I'm the only user and the admin. I have auto log in and it never asks for passwords, (except when i do administrative tasks.) I have looked in the menu (System -- preferences, but i can't find any topic that say's passwords or similar. the only place where I have found a way to change my password is my user ((System -- preferences -- user and groups). I did try to take screenshots but nothing happened, which also is strange. I'm running ubuntu 10.04 LTS Desktop on my Asus 1201n (12").

• Making a new instantiated prefab as a child for existing GameObject

  - by Akari

  I've been searched about how to make these fruit to move as the basket movement if it collided with it, and I've been found that if I want to perform this I've to let these fruit to be a child to the basket game object .. for example : banana.transform.parent = basket.transform; banana and basket each of them of type "GameObject" ... BUT unfortunately this way didn't work !! and I don't know why ?? So now I need to know if it is possible to destroy the banana if a collision with the basket happened and instantiate a new banana in the basket as a child at run time ?!! I need to try this stupid way because I've tried all the other ways and nothing worked :(

• Installing 12.10 messed up Xorg

  - by Ghost

  So I finally decided to upgrade from 12.04 and now my ubuntu install has been rendered unusable. I'm getting the "no screens detected" error from xorg in the console, and no mattr how many times I reinstall it xorg keeps throwing the same errors. I already had to do a bunch of hacks like nomodeset just to get to the console, else I would get an infinite tabulator after the purple boot screen. The machine has a 4200HD IGP, I even tried installing fglrx legacy (4xxx series and below are not supported in regular fglrx anymore) which was a subpar driver in 12.04 but in hopes that the machine would at least work, but nope, nothing at all. Anyone had the same problem? how do I fix it? EDIT: just wanted to add that I upgraded to 13.04 and it didn't solve anything, in fact it might have broken things even further.

• Internal mic not working on Aspire One D255

  - by user50652

  I can't get my internal mic to work with any app other than Sound Recorder. I've scoured the other posts on this topic and none seem to have an answer. I've installed Alsa Mixer, Pulse Audio controls, tried minimising one of the stereo channels but nothing works. The mic is not muted. There is no function key on the keyboard to mute the mic either. The only connector options are analogue mic or analgue input. Neither do anything.

• Fonts totally unreadable

  - by user11181

  I've just upgraded from 10.04 to 10.10 and my fonts are all just small rectangles with nothing in them. They are completely unreadable. EVEN THE FONTS IN THE TERMINAL. Thank god the fonts in my Chromium were ok, because I wouldn't be able to find this site or write this message. So far I've tried to use the Appearance - Font thing and it doesn't work. For some reason there was an error with the fonts during the installation. Please help, this is an utter nightmare...

• Truecrypted Windows 7 missing in Grub2 after upgrade

  - by user287545

  I have an encrypted dual boot Windows 7/Ubuntu System and upgraded my Ubuntu today. Everything went smooth but my Windows is not shown in the Grub2-List anymore. Starting up I have the Truecrypt Bootloader and after entering the Password I get to Grub (now Grub2). There my Windows 7 entry is missing now. Here is my report: http://paste.ubuntu.com/7569182/ Updating Grub did nothing to it. My guess is that within Ubuntu it does not recognize my Windows Installation on sda1 anymore. I can't mount it aswell. I can only mount it via Truecrypt itself. I think I might have to manually insert the menu item for Windows into that Grub config file. I guess that after entering the password in the truecrypt bootloader it would be possible to start Windows if the item was there - just a guess though. Edit: I basically followed these steps to set up my system: Dual Booting Windows 7 with Ubuntu 12.04LTS with Truecrypt

• Should I concentrate on writing code for money or my studies while in college?

  - by A-Cube

  I am college student of Software Engineering. My worries are that while I am concentrating on my studies, my peers are getting down with the code (e.g. HTML, ASP, PHP, etc) to earn money. Should I be worried that I am not doing coding like them? I was asked to be Microsoft Student Partner but I refused because the person what was doing before me told it was just arranging events. Nothing as such like getting with Microsoft and coding. Should I be writing code and earning money as I still am in 4th semester? I only have C++ as learning language in college. Will my job count on these projects that I do, or should I concentrate on studies for now to get maximum benefit?

Once installed, i tried to install ubuntu desktop using sudo apt-get install --no-install-recommends ubuntu-desktop Now I am unable to boot and i get the following error *PulseAudio configured per-user session After this, nothing happens and the ubuntu server does not boot.

• Deploying Asp.net MVC web application [migrated]

  - by Pankaj Upadhyay

  I have been trying to find a neat tutorial, guide or step by step instructions for deploying an Asp.net MVC3 webapp but have found nothing so far. Everyone talks about his version of the stroy and different type of MVC versions. Right now, I have build a simple Asp.net MVC web application which i need to deploy on my shared hosting account. In a very simple manner, I need to know which files should i copy. Do i upload everything in my webproject directory to the server including the controller directory, views, models, content and bin directory ?. What about the Global.asax, web.config, packages.config, myapp.publish.xml. In short, I have no idea which files should be uploaded and which should be not. I am sure of one thing that i need few(MVC and Razor dlls) following dlls in bin directory. Just treat me as someone who has never deployed any website NOTE:- I don't have VS SP1 installed and it doesn't install either. Basically i need a manual procedure.

• Efficient skeletal animation

  - by Will

  I am looking at adopting a skeletal animation format (as prompted here) for an RTS game. The individual representation of each model on-screen will be small but there will be lots of them! In skeletal animation e.g. MD5 files, each individual vertex can be attached to an arbitrary number of joints. How can you efficiently support this whilst doing the interpolation in GLSL? Or do engines do their animation on the CPU? Or do engines set arbitrary limits on maximum joints per vertex and invoke nop multiplies for those joints that don't use the maximum number? Are there games that use skeletal animation in an RTS-like setting thus proving that on integrated graphics cards I have nothing to worry about in going the bones route?

• How to get data from a bluetooth device that is not visible?

  - by jonobacon

  I just bought a Fitbit One which includes Bluetooth 4.0 to sync with mobile devices. Currently libfitbit does not include support for bluetooth syncing, so I would like to see how much data I can get out of the device that I can pass onto the libfitbit devs so that they can explore bluetooth support. I ran: hcitool scan which unfortunately did not return any devices. I also used blueman to scan for devices and nothing was found either. Therefore I am assuming that the bluetooth radio in the device is not visible by default. Can anyone recommend any ways to get data out of the device that could be helpful?

• Failure to start grub with Wubi

  - by Marco Ceppi

  My laptop battery ran down and died while using Ubuntu 10.04 with Wubi. Upon recharge (and restart) selecting Ubuntu from the Windows Boot menu brings me to the typical prompt which says (and I paraphrase): Trying hd(0,0) on Disk... After that the screen flickers to white (for a split second) then black. No grub menu comes up (as I would expect) no cursor, no grub sh prompt. Nothing. I've tried switching TTYs to no avail. As there are no logs, I can't trouble shoot anything. I've run a check disk from windows (on the NTFS partition the root.disk is stored) with no luck. What is causing this failure to load grub (and, by association Ubuntu) - How can I restore my setup and get Ubuntu via Wubi working?

  I have been using ubuntu 12.04LTS for last few months, and now suddenly something has happened to it. As a result, terminal opens on every start up when I login . Although, if i login as a guest, it works fine. I have already used startx command, and tried reinstalling the desktop as well but it doesn't work! If I use ctrl+alt+f9, terminal screen vanishes and a black screen appears, and then nothing happens after that. ctrl+alt+f1 takes me to the command prompt. I know similar questions have been asked here, but i could not find a solution for my laptop. Please help!!

• Newb: First install of ubuntu, no wired or wireless

  - by Ienzo

  Ran 12.04 through a usb drive for a day or so, and had no issues outside of some latency that is more due to the lack of ram on my aspire one D255e than to OS. Had wireless running with no issue, and wired tested as working also. Ran the install and removed windows 7, wireless network is detected but ethernet is not, and neither gets connection. Disabled proprietary driver and rebooted, re-enabled driver and still neither. I know nothing of ubuntu yet! What do? _<
