• How do I change the volume control icon?

  - by Richard Oren Pincook

  I recently switched to gnome 3 (love it!), but the default icon theme was a little dreary and gray, so I switched that back to ubuntu-mono-dark. But now whenever I change my volume, I get this ugly pixelated icon show up. The forum says I don't have enough reputation to post an screenshot, but it's pixelated and ugly with these fuzzy straight blue lines that turn on as the volume goes up. I found identical images in the Humanity and Humanity-Dark icon themes (one example: /usr/share/icons/Humanity/status/24/audio-volume-high.png). I tinkered with the images by changing their names, temporarily deleting them, etc. But it had no effect on the ugly icon. What file is responsible for violating the beauty of my desktop?! Once I find it, I can replace it.

• What's the location of a personal 'gtkrc' file in Ubuntu 12.04?

  - by Kevin Perez

  Good day everyone! I am currently writting a software that makes easy to change default cursor theme with a few clicks. At this point it works well, but applications like Firefox or Lazarus IDE remain with the DMZ-White cursor, everything else is ok. I noticed that when I change the default cursor using my software, and later change the 'personalized' cursor theme using Ubuntu Tweak, it does the job, and the new theme is now applied everywhere. So, what file is need to modify in order to change 'personal' cursor theme? If my software can do this, that would be great! I found that 'gtkrc' is a file where settings of GTK+ are stored. I searched in my home folder but I can't find yet. Can you help me with this, noble people of Ubuntu? :)

• Logic in Entity Components Systems

  - by aaron

  I'm making a game that uses an Entity/Component architecture basically a port of Artemis's framework to c++,the problem arises when I try to make a PlayerControllerComponent, my original idea was this. class PlayerControllerComponent: Component { public: virtual void update() = 0; }; class FpsPlayerControllerComponent: PlayerControllerComponent { public: void update() { //handle input } }; and have a system that updates PlayerControllerComponents, but I found out that the artemis framework does not look at sub-classes the way I thought it would. So all in all my question here is should I make the framework aware of subclasses or should I add a new Component like object that is used for logic.

• Keyboard Layouts Plugin forgets settings, unable find workaround

  - by Honza Javorek

  I use Xubuntu. As everyone knows, Keyboard Layouts Plugin is very, very buggy and it still forgets my settings. It drives me crazy - I have to set them again and again every time I wake up or turn on my laptop. So I found a solution - put into my .bashrc this: setxkbmap -option '' -option grp:alt_shift_toggle cz,us -variant querty That should set my toggle to Alt+shift and my layouts to Czech QUERTY and plain US English as a second one. Voilà, that seems to work! I could use Keyboard Layouts Plugin only as an indicator, that's okay. However, it doesn't work well. The problem is that it ignores -variant setting. More or less. In Keyboard Layouts Plugin I actually see Czech QUERTY selected, but in reality my keyboard types QUERTZ. That's insane :-( Could anyone help, please?

  - by christian ashton

  I'm having serious problems trying to install ubuntu 14.04 on my Toshiba Satellite C850 laptop. Whenever I try to install it it says "No root file system found. Please correct this error from the partitioning menu." I've tried to create new partitions but I don't know what size to make them etc. can someone please help me on this? (Is there a way to create partitions through the terminal? I'm new to ubuntu) but i was on it 2 days ago, laptops crashed and now I can't get past the installation. I've created a new partitioning table just need guidance on which partitions to create and how big to make them. I have absolutely no partitions whatsoever on my hard drive (or whatever the partitions are part of) so it will need to be from the very start. Thanks in advance!

• How to install Radeon Open Source Driver?

  - by Clintonio

  I have an MSI Radeon HD 7850 card. MSI provide no Linux support, and the AMD driver gives me an Unsupported Hardware watermark that does not show up in screenshots. I uninstalled the proprietary driver and found that Unity 3D no longer works, and I really only picked Ubuntu because of the excellent shortcuts provided in the recent versions. Trying to locate the open source driver has been a pain for me. According to the documentation I have read it is pre-included in Ubuntu 12.04, yet there is no Unity 3D support. I tried using the newest drivers from AMD's website, but that also had the watermark. Does anyone know how I can get the open source driver? If not, does anyone know how to remove the watermark. I'm on the verge of going back to Windows.

• Is agile about development or management?

  - by ashy_32bit

  On a debate over what Scrum is all about, I found that perhaps I totally misunderstood the agile thing. It appears to me that Scrum (which is certainly considered an Agile process) is all about managing features and sprints and roles and stuff with nothing to do with TDD, pair programming, CI, refactoring and other developer centric techniques and practices that I though (until now) are the heart of agile. Now I am facing a difficulty ! 1) Is Scrum agnostic to whether developers do agile practices? 2) Can you implement Scrum in a team that does not utilize automated tests? does not perform refactoring or does not adhere to the agile programming practices?

• No wireless network recognized on a Dell Vostro 3560

  - by Itai

  I just installed Ubuntu 12.04 along with Windows 7 on the same laptop - Dell Vostro 3560. Now, on Windows 7 I can access to different wi-fi networks. However, when I am logging onto the Ubuntu section (after re-starting my laptop) - an error message appears: Disconnected - you are now offline When I take a look at my network menu (in the upper bar on the screen), I see that no network is found (and I have a few of them in the area. ). I tried to look around but really could not find a concrete practical solution to this specific problem, would appreciate any solution from anyone out there that had this problem and solved it.

• I'm on Charter's email blacklist, how do I get removed?

  - by Mike Wills

  I am a programmer in a local government agency. I found out today when I got to work that Charter Internet has blacklisted us for our mailing list that we run. This list is used for communicating news and alerts for our residents. Does anyone have a phone # I can use to contact Charter about this? Normally the email approach is fine, but we have yet another snow storm coming and 75 of our customers won't be alerted to a snow emergency if we have one and may possibly be towed as a result.

• how to recover deleted ntfs patition with data entirely while installing ubuntu 13.04

  - by Anson Varghese

  I've installed ubuntu 13.04 onto my hp 2231tx computer. During installation all of my data was erased. I didn't know all of my three partitions would be deleted. I was shocked after finding out that all of my personal data was erased. I didn't know what to do to resolve this problem so I search google for an answer. I found a program called testdisk and I used it to recover about half of my data. Among this data weren't my personal photos and videos. Is there a way to recover the other half?

• Does Webmaster Tools list traffic from ads as inbound links?

  - by Mohamad

  In Webmaster Tools, under the inbound links section, do ads get counted as inbound links? I am doing a review of inbound links on a website and found that most of them are sourced from meaningless blogs and spam websites. Before I accuse anyone of not doing their job properly, I would like to know something: Is it possible that those inbound links were generated when an ad for the website appeared on the spam website? An SEO firm was paid handsomly to generate inbound links and I am afraid all they did was submit material to spam blogs and websites.

• How to make "Chameleonic Ambiance Script" select a lighter hue for dark wallpapers?

  - by Nirmik

  I just started using an amazing script that makes the default "Ambiance" theme use that selected color. More details can be found Here I find this really amazing. But with my wallpaper being as shown below, the selection color, progress-bars color as after running the script are too dark (that can be seen in the following screenshot). I've learnt that what is done is the average color from the wallpaper is selected and then its tint is used (which is always a darker tint). So can I make this algorithm or whatever select a lighter tint of the average color?? Or can it be made to select the lightest color instead of the average color from the wallpaper??

  - by deiga

  Hello all, I've been trying to install MoinMoin -wiki on this webserver, where I have no root access. The server doesn't support wsgi, but it does support cgi/fcgi/etc. I've scoured google for a simple guide on how to accomplish this, but the only guides I found were from the year 2004 or so. Other guides always assumed that one has root access. So can anyone link a good tutorial for my question or just help me out here? Your help is appreciated :) P.S. Sorry if this is the wrong stack -page

• java MainServer gives java.lang.UnsupportedClassVersionError: Unsupported major.minor version 51.0

  - by Paradox

  Compiling is easy but when using java to run the programs, it gives Exception found. I am using Ubuntu 12.04 without internet connections. Also, installed Oracle JDK7 and JRE7. Also did the update-alternatives command on java, javac and javaws. Changed the machine java in /etc/profiles. PATH is pointing to oracle java folder. I did many searches on Google about this topic but each time jdk and jre version are different. Also check version of jdk and jre using java -version and javac - version. Both of them are the same. The system also contains OpenJdk6 and OpenJdk7. So, how do I remove these errors?

• Best way to track multiple sites with Google Analytics

  - by stevether

  I currently have 63 websites (and counting) that I'm tracking on one Google Analytics account, and I'm starting to realize... this is becoming a bit cumbersome. What's the best way to collect traffic data in bulk? Are there other resources out there that are better suited for this task? Does Google offer a bulk option for this kind of thing? Would it be better to make separate analytics accounts? I'm just wondering if anyone else has had found a better solution that manually setting up all these accounts/setting up the tracking codes etc, when it comes to large scale management.

• Revert F3 and F4 behavior in byobu?

  - by James Zimmerman II

  With a fresh 12.04 installation of Ubuntu, byobu's interpretation of the function keys seems to have changed. F3 and F4 will still change the active tab on the current session, but it changes it for all connections. Previously, if you have two active connections to the same user (same session) with User 1 on shell 0/tab 0 and User 2 on shell 0/tab 0, when User 2 pressed F3 , they would be changed to tab 1 while User 1 would remain on tab 0. With the latest version in 12.04, when User 2 presses F3, all connected users are moved to shell 1/tab 1. Is there any way to re-enable the old behavior? I have looked at the /etc/byobu directory and only found backend and socketdir files there. Toggling backend between tmux and screen did not seem to render any difference. Anyone know what, if any, configuration option exist to control this?

• Error installing Windows7 64 bits on VirtualBox

  - by MetaDark

  I am trying to set up Windows in Virtual Box, so I don't need to reboot in the rare occasion that I actually need it. The problem is, Virtual Box doesn't preform any errors when I insert the 32bit installation CD but when I try to use the 64bit installation; What!? I am already using the installation disc! I've checked my BIOS to see if I have SVM (AMD's version of VT) disabled and all I see is "Enabled" I have a K9N6PGM2-V2 motherboard A Triple Core AMD Athlon II A Nvdia NForce 430 integrated graphics card 4GB of RAM An 80GB IDE And a 1TB SATA I don't think the last three specifications matter but just in case XP I am pretty sure the CD isn't broken ( I am going to make sure in just a moment ), what could be the cause to this problem? Edit: The 64bit installation CD is not broken, but I found out when trying to install from the 32bit version that it's trying to upgrade, not preform a fresh install - Odd.

• To what extent do code-signing certificates boost sales of your software?

  - by Dan W

  In the experiences of everyone here, have you found a certificate to boost sales of your (downloadable) program? I produce .NET software and upon clicking the installation file, Windows 7 pops up a message saying the software is from an "unknown publisher" and to proceed with caution. For Windows 8, this appears to be even more prominent, and may adversely affect the number of downloads, and therefore the number of sales. A certificate will help soften this 'warning' by (for example) changing the warning's colour from orange to blue, and give the publisher's name instead of 'unknown'. But I'd like more tangible evidence since many people are obviously used to that message, and may not care and download anyway. So has anyone noticed a jump in sales after the switch?
