• kde keyboard problems Ubuntu 12.04

  - by chazdg

  I have Unity & Gnome 3.4 installed successfully. All Dell keyboard keys work perfectly with both. I installed kde - full via terminal. Everything is working great except for the hotkeys. No calculator, no Mute, nothing. I check which keyboard is selected and choose Dell Multimedia USB Keyboard. No luck. How do I get my Dell keyboard to work with kde - the same keyboard that works with Unity & Gnome 3.4. Thanks in advance for any advice.

• dnsmasq not running

  - by Yevgeniy M.

  i installed ubuntu 12.04 on a netbook with 16GB SSD. To keep the installation small i used the mini.iso i got from here. Everything worked fine, but i noticed that dnsmasq does not get started by NetworkManager. On a different machine i installed 12.04 from a regular iso and netstat shows dnsmasq running and listening on port 53. NetworkManager.conf look identically on both systems. The line dns=dnsmasq is present. Although i do not really need dnsmasq - name resolution works fine without - i would like to know the reason why dnsmasq is running on one system, but does not run on the other and how i could adjust this behavior. Thx in advance!

• "A hard disk may be failing" , but no additional info via gdu-notification-deamon (suggestions?)

  - by blunders

  Got this message after logging in: A hard disk may be failing One or more hard disk report health problems. Click the icon to get more information. On WUBI and 10.04, there was no icon to click, and clicking on made the message go away. After rebooting, the message did not display again. I've got everything on all my hard drives in duplicate, so not super worried about a disk failure, though I am wondering why the message had no info on which disk it thought had problems. Suggestions?

• Problem when scaling game screen in Libgdx

  - by Nicolas Martel

  Currently, I'm able to scale the screen by applying this bit of code onto an OrthographicCamera Camera.setToOrtho(true, Gdx.graphics.getWidth() / 2, Gdx.graphics.getHeight() / 2); But something quite strange is happening with this solution, take a look at this picture of my game below Seems fine right? But upon further investigation, many components are rendered off by one pixels, and the tiles all are. Take a closer look I circled a couple of the errors. Note that the shadow of the warrior I circled appears fine for the other warriors. Also keep in mind that everything is rendered at pixel-perfect precision when I disable the scaling. I actually thought of a possible source for the problem as I'm writing this but I decided to still post this because I would assume somebody else might run into the same issue.

• Is it safe to have no TOS or PP?

  - by JamerTheProgrammer

  I have coded my own forums from the ground up. I have tried my best to make my code as secure as possible and encrypting everything I can. I want to use this forum for a Minecraft server. I have one concern however.... I would like to setup this forum now but having no TOS or Privacy Policy has put me off. Will having none of either cause me any legal trouble in the unlikely event of a data leakage? Thanks

• Unity won't load in Ubuntu 12.10

  - by Nigel

  I just upgraded Ubuntu last night to 12.10 from 12.04. When I rebooted like it asked, everything seemed fine, except one of my monitors had a white screen, and I could not use it. After some tweaking in the AMD Catalyst center, I got it to work, but now Unity wont load, and the bar up top wont load either. I am in suspicion that it a problem with Compiz, but might be completely wrong. Any tips on getting this to work? I am also kind of new at Linux, but I could open a terminal and get Opera open for web browsing, but it is really choppy and slow.

• Why can't the Unity panel be hidden?

  - by newboldrob

  I am a light Linux user. I have Natty installed on my netbook and used to have it dual-booted on my Windows 7 PC. After a total refresh of my notebook off came Ubuntu and I'm back to basics over there. But HERE (I'm running Natty on a HP-Mini) I've decided to poke around a bit to get the best user experience on this little thing. I really like the Unity interface but really hate the static Unity Panel. I have no clue why it's even necessary to be on globally. After all, in the classic interface, both panels can autohide or get filed aside with buttons on either side of the bar. On a 10" screen, real estate is at a premium. What intrinsic purpose does the static unity panel hold for the OS? There has to be a great reason for this thing to HAVE to be here. It ONLY goes away in fullscreen apps and I can't use everything fullscreen Why can the unity panel not be hidden?

• Scale DIV with tiles

  - by user15350

  I am trying to create a repeating background. I have a main DIV with a grid of small 16x16 DIVs. I am trying to scale the main DIV in CSS; when the small DIVs simply have a red background color everything works great, but when there is a background image in the small DIVs then borders become visible between the tiles. This image explains the problem: http://cl.ly/FpNW/o Check the HTML in these examples: With BG-COLOR: http://jsfiddle.net/pTLXw/ With BG-IMG: http://jsfiddle.net/vkpuY/ Does anyone know what is causing this problem and how to fix it? If it is not possible to fix while using DIV, is there another way to do this? Thanks you so much!

• Ubuntu 13.10 not playing DVD videos

  - by John Hill

  I installed Ubuntu Gnome 13.10 on my computer yesterday, and everything seems to be working fine so far, except that it isn't reading video or audio CD's and DVD's. At first, I inserted a DVD video, and it played normally for maybe 30-45 seconds before coming up with a "internal read error" or something like that. I was using the Totem player when the problem occurred, so I tried installing the VLC media player. It wouldn't read the disc at all, so I uninstalled the player. Now, the Totem player won't even begin playing the DVD. The player sometimes doesn't even open up when I insert the DVD, and other times it will but says it can't read it. I've tried several different DVD's and CD's with similar results. The computer is recognizing the optical drive, because when I open "Files", it shows the drive and the disc, but can't play it. Previously, I ran Ubuntu 13.04 with the Gnome desktop installed from the software center, and I had no issues. Any help is appreciated!

• Samsung 7 Graphics Nightmare

  - by tanner

  I just bought a Samsung 7 laptop with the Amd Radeon hd 6490m an I installed the driver. Everything was working smooth and it was rendering nice until I rebooted it. I noticed that it wouldn't boot my favorite game because of a GLSBadRenderRequest. So I went over to the AMD Catalyst program, and it wouldn't fire up because it couldn't find the graphics card!! What do you think is going on? Oh, and that was the latest driver straight from AMD. Im running 12.04lts.

• Choosing the right version control system for .NET projects [closed]

  - by madxpol

  I'm getting ready for my first "bigger" .NET project (ASP.NET MVC 3/4) on which I'm going to lead another 2 programmers and right now I'm choosing the right version control system for the job (plus I'm gonna use it for my future development too). My problem is that I did't use any version control system before, so I would like it to have as fast learning curve and intuitive merging as possible. So far I quickly looked at VisualSVN (I like the Visual Studio integration in it), but I'm reading everywhere how Git is awesome and dunno which one to choose (not limited to these two).. Maybe I'm ovethinking this but I like when everything goes smoothly:) I'd like to hear some opinions from people who used multiple version control systems (preferably on VS projects) what do you think is the less complicated and effective version control system for such a use (one to 5 man projects)?

• Cannot use broadband in Kubuntu

  - by Amanz Linux

  I have 5 months of experience using ubuntu 10:10. And it is clear it is suitable for broadband use. For Kubuntu, I have thoroughly tried everything available, using the 10:10 Kubuntu CD that I have had for the last week. It is very appealing, but in the meantime I am unable to use broadband in Kubuntu. I've tried and tried, thinking that it was possible that the use of broadband in Kubuntu was the same as in Ubuntu, so I have attempted to use broadband just as I used it in ubuntu. But I have failed to successfully test the broadband. Kubuntu was much different from ubuntu. Can anyone help me solve this problem?

• Developing a computer system based on Nand2Tetris [on hold]

  - by Ryan

  I recently finished a book called Nand2Tetris (nand2tetris.org) where I built my own computer system from scratch with its own machine language, assembly code, and a high level language called Jack that's translated to Hack binary. However, I feel like the "computer" I built throughout the course of this book (called the Hack computer) is a bit too simple for various reasons: 1) There are only two registers (D and A), whereas most computers have much more 2) Peripheral devices like mouse and keyboard have to be directly implemented 3) Peripheral devices use a pre-planned shared memory map to communicate with the CPU instead of using interrupts (which aren't covered at all) 4) Jack (the high level language) code doesn't compile to Assembly code directly, instead it compiles to an intermediate language, which in turn gets translated to Assembly. 5) There is no ROM or permanent storage device, everything is stored in RAM 6) No support for colored monitor, networking or sound I would like to build a more complicated computer system now based on what I've learned from Nand2Tetris. Does anyone know of any good resources or books to get started on this? (BTW by computer system I mean software that can emulate the hardware of a virtual computer with its own unique instruction set)

• Port numbers appended to anchor tags

  - by glifchits

  I've built a static site. Locally, when I serve the content with python -m SimpleHTTPServer everything behaves normally, but when I copy the HTML onto the server and browse the site at the server's URL, some links will have a port number appended to the domain. For example: url.com:84/path where the correct path is url.com/path. The port number is usually different, always between 81-85. It is an Apache server. I'm not experienced with web server configuration, and I'm not the admin of the server. Let me know if there is more information that can help solve my problem. ~> cat /etc/*release* SuSE SLES-8 (i386) VERSION = 8.1 UnitedLinux 1.0 (i586) VERSION = 1.0 LSB_VERSION="1.2" DISTRIB_ID="UnitedLinux" DISTRIB_RELEASE="1.0" DISTRIB_DESCRIPTION="UnitedLinux 1.0 (i586)"

• React to a modified directory

  - by Ghanshyam Rathod

  In linux everything is considered as file, Now if I want to find only folders/directories not the files then how can i do that? I am getting all the modified files with the following command. find /Users/ghanshyam -type f -mmin -5 -print My goal is to generate the log file with all the modified/access folders. Here two options are available. create a module and call every time when a folder is modified (this one is bit difficult because I need to check particular event) create a cron task that will run after every 5 minutes. cron task will execute shell script and generate the log entries with the modified folders. Do you have any other option to do this task ?

• What options are there for integrating with payment gateways? [closed]

  - by Rowland Shaw

  It seems that there are only two types of payment gateway service out there at the moment; Either that the entire cart logic is handled offsite (with something like Paypal's Standard option) or the other option being that you need to go through the certification for handling credit card numbers and doing pretty much everything yourself. Ideally, for the project I'm working on, I'm after a bit of middle ground such that I can handle the cart on-site, and only pass over to a payment gateway (with an order amount, billing & delivery details, and order ref) for them to handle the card details, before passing back. I'm sure that I've used e-commerce sites using this pattern before, but I cannot find any payment providers out there that offer this sort of option, so are there any? The only over requirement we have at present is that it must accept orders in Sterling.

• practical way to learn C?

  - by jondavidjohn

  I want to dig into C and normally when I want to learn a new language I think of a simple/attainable project goal that has some practical purpose (make use of an api, automate a task, etc...) I'm having a harder time coming up with one for C mainly because everything I read points to the fact that C's primary use currently is in embedded systems and more complex software projects like operating systems. Does this point me to the fact that I don't need to learn it or that I just need to be a bit more convoluted in my learning strategy? References to practical learning resources? (tutorial/how to that produces an end result that has some purpose/benifit)

• How can I force the Nautilus sidebar text color to stay white in my Ambiance modification?

  - by WarriorIng64

  This is related to How can I change the color of this part of Nautilus for my Ambiance theme modification?, which has just been solved. Now I have a new issue. As shown below, the text color for the sidebar does not want to stay white unless it is selected. It did earlier, but now it's not and I'm not sure why. How can I force that text to stay white in the theme files? (See the linked question above for a reference as to what changes I made; everything else is the same as regular Ambiance.)

• Coordinating team code review sessions [closed]

  - by Wade Tandy

  My question has two parts: 1) In your team or organization, do you ever do in-person code reviews with all or part of a team, as opposed to online reviews using some sort of tool? 2) How do you structure these meetings? Do you choose to focus on one person's code in a given meeting? Do you look at everything? Take a random sample? Ask people on the team what they'd like to have looked at of theirs? I'd love to add this practice to my development team, so I'd like to hear how others are doing it.

• useradd instead of adduser,

  - by Chris at Well

  So I installed Ubuntu 13.04, set up sftp, that's all good. Setting up vsftpd for regular FTP users (we need those too, sadly. sftp isn't for good for all our purposes), i accidently used useradd to create one of the users instead of adduser. This user can't log in to frig all. I tried to delete the user and re-add it with adduser, no dice. It creates the user, but the permissions are frigged up. Any idea how I can completely undo a useradd, so that I can adduser this person and have everything coming up Milhouse again? Sorry boys, I frigged up hard.

X server's killed immediately, I can see the console only. What do I have to do now?

When I run the install command it says DHCP3 is installed, but when I type in the following command to start DHCP (sudo /etc/init.d/DHCP3-server start it says the command is not found.
