• Firefox installed on my ubuntu 12.04 machine but I am unable to connect to the internet(Nobody know???)

  - by Chella

  every other browser installed is working fine..! except this Firefox. what are the things that I need to check, to make firefox work on my computer. I am a newbie for ubuntu. I tried googling not got enough and clear information. Please help me. Thanks in advance..! This is the error that I am getting just before launching of the application..! Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features.

• How to display time in the top panel?

  - by Mörre

  I thought I already had the time up there in the top bar, and it may have been so in previous Ubuntu versions (don't remember, my Ubuntu laptop is just one of three computers I use). Only that I just noticed - me being someone who never wears a watch, has the cellphone turned off 95% of the time and relying on the computer to tell the time - that there is no time being displayed anywhere, and I had expected it in the top bar on the Unity desktop. I searched around but found no obvious solution, but I'm sure someone immediately knows how I can get my time (back?) into the top bar?

• Looking for parallel programming problem

  - by Chris Lieb

  I am trying to come up with a problem that is easily solvable in a parallel manner and that requires communication between threads for a test. I also am trying to avoid problems that require require random waits, which rules out dining philosophers and producer-consumer (bounded buffer), two of the classics. My goal is for the student to be able to write the program in less than 20-30 minutes in front of a computer not knowing of the problem beforehand. (This is to prevent preparation more than to come up with something novel.) I am trying to stress the communication aspect of the program, though the multi-threaded nature is also important. Does anyone have some ideas? Edit: I'm using Google Go for the language and testing comprehension of the goroutines/channels combo vs an actors library that I authored.

• Windows Wireless Drivers - Install

  - by Justin Y.

  I have nearly ended my journey of making a dual-boot windows xp and ubuntu computer. Along with version 12.04, came the problem with my NetGear WNDA3100v2 wireless adapter. It wasn't compatible. My last step in my adventure is to install the software called Windows Wireless Drivers. I have internet access on my laptop and a flash drive. It would be preferable to receive a link to this program, because I see no link on the website, and I can't download it from the Ubuntu Software Center. Thanks.

• Neverwinter Nights does not run in 12.10

  - by 0x0me

  I recently installed a fresh version of Ubuntu 12.10 on my notebook. Then I copied the backup copy of my nwn folder from my old 12.04 install on the same computer to the new installation and tried to start the game. The terminal prompt disappears and top shows some low activity on nwmain, but there is neither showing up the game graphics nor plays any music. Any suggestions how to fix it? The game runs fine using the same setup expect for running on 12.04. Kind regards and thanks in advance

• How to bridge the gap between university and job requirements

  - by user1762636

  I study physics and computer science and both studies include minor programming tasks whereas larger tasks are only (potentially) a part of larger projects like for your thesis. When I look at job postings for scientific jobs e.g. in the area of HPC they usually ask for "extensive programming skills in C/C++ and HPC" or the like. This is what I would like to achieve, but frankly I don't know how. I don't mean to mourn, but you can imagine that studying physics/CS means having a busy schedule so I couldn't even work part time as a research assistant to get practice without negative influence on my grades. The second problem is that I lack ideas on what to code in my spare time. I would like to do something useful but even for open source projects you apparently need a whole lot of time and depending on the type of software a lot of experience to be useful. I would be grateful for any advice you can give me.

• issue with vmd install not working any more. lubuntu 12.10

  - by Magpie

  I had vmd working on my lubuntu 64 bit but all of a sudden I was getting errors when I tried to run it. I tried reinstalling it but no joy. The error I now get when I try to run rlwrap: No match. I don't use make unless I have to so I don't know all that much about it. I have removing vmd completely to see if that helped. I tried the suggestions it made (I am sorry, I can't remember the details but it was moaning about CUDA and my graphic drivers for a while. I had not updated it or anything. It was fine until I went away from the computer and came back to it like that. If nobody can help I will try reinstalling my system and see if that helps.

• SkyDrive Pro Limits

  - by Sahil Malik

  SharePoint 2010 Training: more information I’m putting this here, because I know I’m gonna forget it :) Overall size limits - On an on premises installation, there are no fixed limits on storage. You can configure it as you wish. For Office 365 (SharePoint Online), the limit is 7GB per user. Number of items (documents and folders): You can sync up to 20,000 items in your SkyDrive (personal library). You can sync up to 5,000 items from other libraries, per library. In other words, you could sync 10 libraries (for example), with each library having up to 5000 items. Third, site limits: No fixed limits. It depends on your computer's resources. Hooray! and Happy SharePointing! Read full article ....

• How to access UbuntOne when it asks for default keyring which has never been set?

  - by obu-tim

  I am trying to set up UbuntuOne on a new computer and after I enter the email and password, it asks for the keyring 'default'. I don't know what it is and I never set it. Makes it difficult to enter so it seems to be a counterproductive security default. I understand that if autologin is set the keyring is called. I tried setting the main user to need a password but if I reboot it doesn't ask for the password so it sort of autoboots still. So How do I set the keyring default password? If I can't set it I can't install UbuntOne

• Fujitsu B6220 laptop, sometimes my desktop freezes upon resume from standby

  - by user89756

  I installed Ubuntu 11.10 on my Fujitsu Lifebook B6220 laptop just before 12.04 was released. I can not remember if I had this issue with Ubuntu 11.10 as I updated the install to 12.04 about a week after 12.04 came out. My problem is that sometimes upon resume from standby my desktop is frozen. The keyboard, touch pad, and touchscreen work, but there is no response from the desktop. I can ctrl-alt-f2 and log in and then from there I just reboot the computer. This happens about 50% of the time when I resume from standby but I have not noticed a distinct pattern. I have thought about reinstalling 12.04, since I upgraded 11.10 to 12.04 instead of a fresh install. But I have customized my laptop a lot and I would prefer to avoid reinstalling it, I'm not even sure if that would fix it. Anyone have a idea what might be the problem? If I should submit this as a bug, could someone point me in the right direction please? Thanks, Matt

• I cannot change the screen brightness

  - by user1793249

  here's my problem: Ever since I installed Ubuntu 12.10 on my computer I haven't been able to change the screen brightness, it was always set to the maximum. I did take a look at this post: Decrease Backlight Below Minimum And it helped me resolved the issue with the unbearable brightness, however one problem persists: I cannot change it through "Brightness & Lock" or the function buttons (F2 and F3), when I press the buttons, the animation shows up but nothing happens. I tried the following: http://www.refreshit.info/2012/08/solved-brightness-increase-and-decrease.html It did nothing... If it helps: I have an HP-dv6 6185la, it has an ATI Radeon 6770M HD card and an Intel HD Integrated Graphics Card It only detects the "Intel® Sandybridge Mobile" Thanks in advance.

• Google Chrome Browser does not display the images from Local network or local host? [migrated]

  - by Arjang

  While developing and testing a site on local network I have noticed that while IE/FireFox would display the images coming from URL's like "http:\mypc" or "http:\localhost" or ip adress on the netwrok , google chrome on Galaxy, Windows Machine, or google Android will not display the images. After having burned too many hours trying various CSS, image src tag, html document description tricks, I have given up. During my search I found (and lost) the link to chrome forums regarding this issue that seemed to say it is just so by users. Anyone has any more information on weather it is possible to view images on local host/computer name on netwrok or ip adress?

• usb keyboard stopped working in terminal window after update from 13.04 to 13.10

  - by Jim

  When I start the computer, I am logged in automatically. Using the keyboard, I type Ctrl+Alt+t, which brings up a terminal window, just like it should; however, nothing happens when I attempt to type into the terminal. If I change over to the guest account, I can type into the terminal, but (different problem here, I'll ask it separately unless someone is kind enough to answer it here) my password doesn't work for sudo or anything else. Elsewhere I read that Language support could fix it, but that won't accept my password either - and no, I haven't changed it lately. Also, my Plex Media Server seems to have disappeared. I'll re-install everything if necessary, but I sure would rather avoid that if possible

• Strange sound distortion using headphones

  - by Luca

  When I use headphones, the sound comes out distorted. Voices sound as if they were far away, while instruments that should be in the background sound enhanced. When I play songs with the laptop's integrated speakers everything is alright, and the headphones work normally when plugged into another computer. I tried reloading ALSA and reinstalling some of the related packages, but nothing worked. I'm using Xubuntu 12.04 32-bit. Thanks to anyone who will suggest me how to solve this problem.

• Xubuntu and other Debian based distros slow

  - by William V

  I have a Compaq Presario SR1950NX desktop computer with the AMD64 3800+ processor and 1GB ram and it seems that Ubunutu, Xubuntu and Lubuntu are all laggy. Things seem to be slow such as clicking on menus and opening programs and the UI renders in peices. When using the browser the system slows down considerably. I ran the TOP command and I do notice that xorg hits 30 to 40 percent cpu when running the browsers. I have tried these distros on a spare P4 machine and it is even worse. As long as I don't have a several things open at one time I can manage to get around although sluggishly. I also notice that I can't get debian based distros to install in 64bit (crtc6 failure) only in 32bit. Can anyone tell me what is it that I might be doing wrong? I have an integrated Nvidia card and have tried several of the recommended drivers which sometimes result in no boot screen upon reboot. Thanks

• How can I learn to write idiomatic C++?

  - by yati sagade

  I am a computer science student, and as a result, I was taught C++ as a better version of C with classes. I end up trying to reinvent the wheel whenever a solution to a complex problem is needed, only to find sometime after that, some language feature or some standard library routine could potentially have done that for me. I'm all comfortable with my char* and *(int*)(someVoidPointer) idioms, but recently, after making a (minor) contribution to an open-source project, I feel that is not how one's supposed to think when writing C++ code. It's much different than C is. Considering that I know objected-oriented programming fairly well, and I am okay with a steep learning curve, what would you suggest for me to get my mind on the C++ track when I'm coding C++?

• Why can't I access hw:1,0 until gstreamer-properties is run once?

  - by Shadd

  Not necessarily an Ubuntu-specific question but I wasn't sure where else to ask. I have an AverMedia DVD EZMaker 7 which plugs into USB and works well on Ubuntu 12.04. I downloaded and installed the official drivers without error. However, when I try: gst-launch alsasrc device="hw:1,0" ! alsasink device="hw:0,0" it tells me: Setting pipeline to PAUSED ... Pipeline is live and does not need PREROLL ... Setting pipeline to PLAYING ... New clock: GstAudioSrcClock which is the normal output, however there is no audible sound. Trying the command again doesn't help. If I run gstreamer-properties and close it right away (don't need to touch any controls), THEN the gst-launch command works. If I unplug the device and plug it back in or restart the computer, I have to run gstreamer-properties again. What is gstreamer-properties doing that enables the audio?

• Best video recording & mixing software for Ubuntu

  - by ???? No

  I'm searching for a quality software for recording video streams and mixing 3 cameras' streams and photos. I need it also for online streaming on a website. It could be a commercial software, doesn't have to be open source or free. I just don't have a clue if there is something like this. Thanks in advance. P.S. It's for Ubuntu 12.04 P.S.S. Maybe my definition is not correct or full, so I have to add - I need the program for live broadcast and recording on the computer at the same time.

• Mic not working when vga connector removed

  - by yygyt

  I have a computer that should run continuously without any connection to a monitor. For developmental purposes I have been keeping the vga connection with the monitor and experienced no problem until now. When I start the machine removing the vga connection beforehand, external microphone does not work. At first I didn't know anywhere to look and see the problem, but after a google search I saw that there is a command as alsamixer I ssh the machine end type alsamixer when it is connected to the monitor, here is the result If I remove monitor connection and reboot again, and then type alsamixer, I see the error, $ alsamixer cannot open mixer: No such file or directory I suspect that this error is related to X somehow. I really don't know anything about what goes beyond. This machine needs to work without any connection to a monitor. I would deeply appreciate any suggestions.

• Can I launch Windows 8 with grub?

  - by Laurbert515

  I accidentally deleted the boot loader for Windows 8 (I think). Here is the situation: I just got a new computer with 2 HDD (sda, sdb). Now, all of the windows OS was installed on sdb (all except for about 210 MB on sda). I formatted sda and installed Kubuntu 12.04.2 (which only loads the terminal because it says it can't find a screen, but that's another story!) Now, my Windows 8 data and NTFS partitions, etc. are still on sdb and untouched. Unfortunately, I cannot see an option to boot into Windows 8 in grub, so is there a way that I can go about using grub to point to the Windows 8 OS? The only other option I can think of is to buy a fresh copy of Windows 8 and install it fresh (no, I didn't create a backup USB because I'm an idiot ...)

• category title and affect on SEO and ranking [closed]

  - by Mark

  We are working on a jobs and skills website (similiar to Skill Pages) and are deciding on the names of categories. Rather than having loads of categories and sub-categories like, for example, Builder, Electrician, Carpenter etc, we would like to have more general and easier on the eye category names. So for example we have House, Computer, Education, Art etc. So a builder would be in category House and a few others. Will this style negatively effect our SEO and ranking? And if so, should we abandon and go back to traditional categories and sub-categories?

• How do I get drivers working for an Nvidia GT560i on 12.04?

  - by keepitsimpleengineer

  I been using a test Xubuntu 12.04 LTS on my 64 bit workstation, because Ubuntu has dropped support for the nvidia graphic adapters my 10.04 LTS and I haven't been able to get them working. Now update manager has upgraded the kernel from 3.2.0-30-generic to 3.2.0-31-generic, and failed to produce a working nvidia module that the X server can load. Fortunately, when launching the 3.2.0-30-generic kernel, I still have use of the X server. Does anybody know a work-around or fix for this? I'm really worried, this is the last working Ubuntu distribution OS on the computer and I don't want to give up on Ubuntu. Details of problem here.

• After one has made many grid based puzzles how does one make then into a PDF ready for printing

  - by alan ross

  After one has generated many grid based puzzles like sudoku, kakuro or even plain crosswords and now one has to print them in a book. How does one make a pdf (book file) from them automatically. To explain the question better. One has the puzzle ready in computer format like ..35.6.89 for all nine rows. The dot being the empty cell. How does one convert then to a picture on a PDF page complete with box, automatically without doing them individually and then print a book from the pdf file. As can be seen there are other things also printed on the page all this is done automatically.
