  • How to get Skype's indicator on 12.04 [closed]

    - by herpson
    Possible Duplicate: How do I get the Skype status icon back? (on panel/tray) After upgrading to 12.04 (64bit), I've started installing the programs that I used to have on 10.04, one of them is skype. Downloaded the .deb file from Skypes website and installed it using the Ubuntu software center. However, when I launch skype, it doesnt add an indicator to the top menu like it used to, which means that when I click the 'x' on the program's window, it goes away, I cant reopen it, and I'm still logged in. How can I get the indicator back? Thank you

  • Rolling With the Punches

    - by D'Arcy Lussier
    So I’ve been tweeting the last little while “Rolling with the punches” and I’ve had some people ask me what that meant. Whether you’re running a conference (like I am this week), or a project, or a birthday party for a 2 year old, you need to be ready to handle those things that are unexpected. Risk mitigation can only go so far and its at those times that you need to become resourceful. So let me tell you what the last few days have been like. Today is the first day of Prairie Dev Con Winnipeg, a conference that I run. On Friday I was informed that my keynote speaker had lost his voice, one of my speakers had a family emergency and had to back out, and I got a warning from another that he was travelling over the weekend and if there was a storm or something he may not be able to get back by Monday for his talk. A storm didn’t happen, but their car did break down and he was delayed. Finally, Saturday night I took my printing order to Staples. It was at 5 and they closed at 6, and I had a bunch of surveys to be printed and cut. The girl working said that she’d have it ready by the next day (Sunday). Her intent was to come in the next morning and finish the job. Unfortunately, she had to be hospitalized that night and never made it into work…and never informed anyone of the remaining work. They found out at 3pm when I came to pick it up and there was no way they’d be able to cut everything in time. So how did we roll with these punches? - Miguel, my keynote speaker, was a trooper and was able to do the keynote but asked that his session get moved from Monday to Tuesday. This is why I wait until the last day before printing out schedules, they can change up to the event and even later. - I was able to move some sessions around to accommodate my stranded speaker and fill the empty slot from the speaker that couldn’t make it. - Staples was able to get me half the cut surveys so I took those and my wife will pick up the rest today. I altered how we’d collect session surveys, and actually I think it’ll work better. So all of this is to say, plan but also plan for what you can’t plan for – there will be things that happen that blindside you, that you’re not sure how to handle or solve. Stop, take a deep breath, and don’t feel that you need to limit yourself to the boundaries that you initially set for yourself. Roll with the punch and learn from it so that you can avoid the blow next time. Now, back to the conference! D

  • How do I correctly upgrade the kernel on Ubuntu 10.04 LTS?

    - by lal00
    I'm trying to upgrade the linux kernel from 2.6.32-34 to the latest update of that series, which appears to be 2.6.32-34. I ran: sudo apt-get update sudo apt-get upgrade At this point i was told that some packages were kept back: The following packages have been kept back: landscape-common linux-headers-server linux-image-server linux-server I proceeded to install those and then to autoremove the kernel (that's what apt-get recommended): sudo apt-get install linux-headers-server linux-image-server linux-server sudo apt-get autoremove My problem is that after booting, and running uname -a i still get the 2.6.32.34 kernel. How can I guarantee that the latest kernel will be loaded? thank you in advance.

  • WiFi, No ping, other works fine

    - by Linux Mom
    I installed Ubuntu 12.04 LTS for my mom, this runs OK. However recently, I switched back and forth between encryptions on our WiFi Router from WPA-PSK to WEP and back again to WPA-PSK, same password. Now this old laptop won't even ping the gateway on the router, although the nm-applet shows connected. I tried re-adding the network and putting in the BSSID. I did this over again sometimes just to verify. I tried with my 3G Tethering on my phone, it works fine, can go online too. My other Linux laptop can go on the same wifi as well as my phone. And this laptop used to been online on the same network, same password, same encryption (WPA-PSK) What can be wrong ? Does it need a serious kick in the butt or removing some cached authorisation somewhere?

  • Particle system lifetimes in OpenGL ES 2

    - by user16547
    I don't know how to work with my particle's lifetimes. My design is simple: each particle has a position, a speed and a lifetime. At each frame, each particle should update its position like this: position.y = position.y + INCREMENT * speed.y However, I'm having difficulties in choosing my INCREMENT. If I set it to some sort of FRAME_COUNT, it looks fine until FRAME_COUNT has to be set back to 0. The effect will be that all particles start over at the same time, which I don't want to happen. I want my particles sort of live "independent" of each other. That's the reason I need a lifetime, but I don't know how to make use of it. I added a lifetime for each particle in the particle buffer, but I also need an individual increment that's updated on each frame, so that when PARTICLE_INCREMENT = PARTICLE_LIFETIME, each increment goes back to 0. How can I achieve something like that?

  • Communication between Box2D and libGDX Stage (Scene2D) running in separate threads

    - by atok
    I'm making a physics based 2D game using libGDX and Box2D. I want to move the execution of the simulation out of render thread. I use immutable messages and the BlockingQueue to pass the information about player actions. The Box2D applies forces and runs a frame of simulation. In the next step I would like to sync back the changes and update Scene2D Actors accordingly. Making an immutable copy of the state of the game world and sending it back using Gdx.app.postRunnable() is one option but it seems inefficient. Is there any other option?

  • 12.04 reboots rather than shutting down

    - by Luca
    I have a ruvo with a fresh installation of 12.04. When I try and shutdown the computer reboots. Until I upgraded (by doing a fresh install) I ran it with Ubuntu 10.04 and I didn't have this issue. I have tried sudo shutdown -h now sudo shutdown -P now sudo init 0 sudo poweroff All of these cause a reboot. I have added acpi=norq to my grub file as suggested by someone in the first post below. This is being used as a mythtv frontend and I would like the power button to shut it down. I have modified the button to perform a shutdown -h now, but this too causes a reboot. I have studied the posts below and tried some of these ideas, but with no luck so far. Why do I get a reboot instead of a shutdown? Ubuntu 12.04 not shutting down properly Stuck on reboot and shutdown Shutdown does not power off computer

  • How to get Unity interface on my PC?

    - by Prarobo
    I downgraded by PC to 11.04 from 12.04 2 days ago. I was using the Unity interface and I am quite used to it. Today when I started my PC, I got a message (after the login screen showed) saying that my system does not support Unity and it automatically defaulted me to the classic interface. Now when I start my PC, even when the interface choice selected is Ubuntu and not Ubuntu Classic, it falls back to the classic interface. Any advice on how to get Unity back?

  • Developing web sites that imitate desktop apps. How to fight that paradigm? [closed]

    - by user1598390
    Supposse there's a company where web sites/apps are designed to resemble desktop apps. They struggle to add: Splash screens Drop-down menus Tab-pages Pages that don't grow downward with content, context is inside scrollable area so page is of a fixed size, as if resembling the one-screen limitation of desktop apps. Modal windows, pop-ups, etc. Tree views Absolutely no access to content unless you login-first, even with non-sensitive content. After splash screen desapears, you are presented with a login screen. No links - just simulated buttons. Fixed page-size. Cannot open a linked in other tab Print button that prints directly ( not showing printable page so the user can't print via the browser's print command ) Progress bars for loading content even when the browser indicates it with its own animation Fonts and color amulate a desktop app made with Visual Basic, PowerBuilder etc. Every app seems almost as if were made in Visual Basic. They reject this elements: Breadcrumbs Good old underlined links Generated/dynamic navigation, usage-based suggestions Ability to open links in multiple tabs Pagination Printable pages Ability to produce a URL you can save or share that links to an item, like when you send someone the link to an especific StackExchange question. The only URL is the main one. Back button To achieve this, tons of javascript code is needed. Lots and lots of Javascript and Ajax code for things not related with the business but with the necessity to hide/show that button, refresh this listbox, grey-out that label, etc. The coplexity generated by forcing one paradigm into another means most lines of code are dedicated to maintain the illusion of a desktop app. What is the best way to change this mindset, and make them embrace the web, and start producing modern, web apps instead of desktop imitations ? EDIT: These sites are intranet sites. Users hate these apps. They constantly whine about them, but they have to use them to do their daily work. These sites are in-house solutions, the end-users have no choice but to use them. They are a "captive audience". Also, substitution will not happen because of high costs. But at least if that mindset is changed, new developments would be more web-like.

  • Flashing screen hovering over menubar on left side

    - by iwekb
    Just installed Ubuntu 10.10 netbook version on an older Dell Laptop (no other operating system installed). When hovering with mouse over menu bar, the full screen changes to default coloured back ground shortly and then back to normal (as after start-up) again. And that each time the mouse is over any of the (default) icons on the menu bar. I am not able to select any icon. No left or right click works on icons or anywhere on the menubar apart from the left top small icon, white Ubuntu logo, and the right top small icons for WiFi, sound, mail, shut-down etc. Those icons work. I tried re-installation again and all patches are downloaded. Same problem. Problem is that I can't enter commands either to reduce e.g. the swappiness (if that would be of any help). Can somebody help me that encountered similar problem or knows a resolution?

  • debian (stable), google chrome, sencha and tranparency [closed]

    - by Kim Alders
    I am a bit unsure where to post this, but i guess it should be here, as it has to do with rendering in a browser. We have a sencha touch 1.1 application running in Google Chrome. On mij own computer (ubuntu) there are no problems. On the touch screen attached to a computer running debian-OS, transparency is shown as semi-transparent. It happens on sliders. Sliders have a button on them. This button is rendered bij sencha with CSS. It is NOT an image. Anyone has any idea how to get it 'nice' on debian too

  • Ubuntu thinks I have two displays

    - by ResidentBiscuit
    When I first installed Ubuntu I noticed that my mouse would flicker a lot, which caused me to investigate. I remembered back when I ran Fedora I had an issue where it thought I had two displays (hp-dv7 4285dx laptop). In Fedora, this didn't cause any issues. In Ubuntu, it causes the mouse the flicker a lot. The fix I've been using is to just go into settings displays and disable the display that doesn't actually exist. The only problem is that this is not permanent. Each time I start up Ubuntu, I have to go back in and disable this display. They're each just titled "Built-in Display", and have the same resolution. My laptop does have two graphics cards: one on-board and one dedicated. I'm not sure if maybe that is causing is an issue? Any guidance towards this would be great. Thanks!

  • Restrict user to folder (not root) on VSFTPD in Ubuntu

    - by omega1
    I am a new Linux (Ubuntu) user and have a VPS where I am setting up a backup FTP service. I have followed this guide, which I have managed to do correctly and it works. I have two users (user1 and user2) with the same directory /home/users/test. user1 can read/write and user2 can only read. This works OK. When the users log in, they go straight into the correct directory /home/users/test, but they can navigate back down to the home directory, which I do not want to happen. I cannot seem to find out how to not allow this, and have them not be able to navigate back to the /home/ or /home/test/ directories.

  • Getting Started with 12.04 LTS Problems

    - by mark
    Okay previously I used ubuntu 10.04 in Desktops and Loved it! I bought a newer Toshiba Satellite with an i7 CPU, 8GB Ram, 1TB HD, first thing I tried to do was install Ubuntu 9 on it then I found out it was no longer Supported. (I gave my 10.04 disk away) So I tried installing Windows 7 and experienced SO MANY problems, I am going back to try 12.04. Starting all over again. After installing 12.04 Wireless was Detected yet said it was Disabled by a Hardware Switch. Went read through the Message Boards found Solution which was Sudo rf Kill All. Okay all excited I would finally get my Ubuntu to finally work I rushed back to my laptop from the internet cafe, and went looking for the TERMINAL input on my Ubuntu 12.04, and I cannot find the Terminal. If I can't find the TERMINAL how Can I enter any Sudo Stuff? So I guess the first question is Where is the Terminal Located in 12.04? Thank you.

    - by SwissStar
    I don't even know how long it's been but I had given up. until now. My screen does not come on AT ALL, not even and the Bios loading screen. I have to connect it to my TV in order to see.

I know that for sure, because I remember running an update and BAM . That was it for the screen. How could I restore my screen back to Life ? I have a Nvidia Graphics Card.

  • Need your opinion: which domain should I use for the blog?

    Reader new to my blog might have wondered why blog lives in a .NZ domain: to make a long story short is because when I started my blog I was soo excited about my relocation to New Zealand that I registered a .NZ domain. Then I came back to Italy, and started to work in Milano. Last autumn I had to chance to go back to New Zealand again, but at the same time the offer to work for an European Institution arrived. And then my .net.nz domain didn't make sense any more. And because it seems like I've...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • How do I remove Skype 4.3 from Ubuntu 14.04 LTS (32-bit)

    - by Lucas W
    I installed Skype on my nephew's new Ubuntu 14.04 LTS machine, and now we've decided to remove it. But I'm not able to locate it in my Installed programs section of Ubuntu Software Center. I'm able to call it up by opening the debian package, Software Center opens it up, but where I would normally see the "Remove" button, I have a "Reinstall" button. For the life of me, I can't figure out how to uninstall Skype. Any suggestions? In case you're wondering I used the version of Skype designed for 12.xx, as there was no option available for Ubuntu 14.xx.

  • Cocos 2D - Hold down CCMenuItem

    - by Will Youmans
    I am using the following code to move a CCSprite left and right. -(id)init{ CCMenuItemImage * moveLeftButton = [CCMenuItemImage itemFromNormalImage:@"Move Left Button.png" selectedImage:@"Move Left Button.png" target:self selector:@selector(moveLeftVoid:)]; } -(void)moveLeftVoid{ id moveLeft = [CCMoveBy actionWithDuration:.3 position:ccp(-10, 0)]; [_mainSprite runAction:moveLeft]; } This does work, but only as a single tap. What I want for the CCSprite to move continously in that direction when the CCMenuItem is held down. Then when it's released the character stops moving. If you need to see more code, please just ask. :) Thanks

  • How do developers find the time to stay on top of latest technologies?

    - by u2sonderzug
    I was a freelance web developer until circa 2004 when I started going down the management route but have decided to try to get back into development again (specifically JavaScript and HTML5 web/mobile web apps) and I really get the impression to be truly good at these and similar fast moving technologies a constant amount of time is required to be set aside to invest in getting better at existing skills in addition to learning new skills. I understand right now since I am getting back into things there is a pretty steep learning curve, but seeing how good many guys are out there - the only way I see of getting up there is putting in a serious amount of time. For those working as fulltime developers, what I am trying to understand is this - on most days, how much time in the office is spent actually grinding out code compared to learning/research. I could easily spend 2-4 hours daily getting on top of the best ways to go about doing things. Do most good developers who are employed full time invest significant hours outside of work sharpening their skills? Or maybe I'm looking at all of this completely wrong?

  • How do I get the name of a package, modify and install it?

    - by Ken
    I'm not very familiar with Ubuntu or Linux, but I'm a programmer, and some people told me that you can just go ahead and modify your system. So my question is, how do you go on about that? For instance, If I'm interested in modifying the behavior of the button or the desktop icons, or whatever it is: How do I get the source code? I guess I need the package name and download it. But how can I get the package name? Let's say I want the button package, where do I look to get the package name? is there a list on a website or a help file? Once I modify it, how can I replace the original with the new one? P.S. I had some troubles finding the right tags, feel free to edit them

  • Binding hotkey for toggling wireless card state - System76 Bonp3

    - by user109076
    Recently, my wireless card shut off on my laptop (System76 Bonp3 running Ubuntu 12.04 LTS). Awhile back, my keyboard had a meeting with a cup of coffee, and my F11 key no longer works. The key binding for turning my card back on happens to be Fn + F11, so I cannot turn my wifi on. The only solution I can think of is to somehow change this to be bound to another key. I'm looking for the script that handles this particular hardware switch so I can bind it elsewhere.

  • How do I make the 'Shut Down the Computer' window be monochrome ?

    - by Agmenor
    When I hit the power button of my computer, a window titled 'Shut Down the Computer' appears. It gives a few options, including shutting down or restarting. This window is different following the context I hit the power button : when logged in and seeing my desktop, it includes colourful icons (red for shutting down, for example). when I am not logged in yet, the icons are monochrome and a little bit more stylized. I clearly prefer the last type of icons : how do I set them as default whatever the context of use of the 'Shut Down the Computer' window ?
