• Upgrade to 12.04, nothing in dash, no date&time

  - by Nicolas

  I've upgraded from ubuntu netbook remix something to 12.04 lts, and I've got two issues. (Got an Asus eeePc 32bits, Intel 945GME x86/MMX/SSE2 and Intel Atom CPU N270 @ 1.6Ghz x2) Nothing in the dash. Only the "home" tab, other tabs are missing. No search result whatsoever. Missing elements in the system panel, privacy and date&time. No date&time on the right corner either. I've tried to reset unity with the terminal but the process was a whole mess full of errors. It did show date&time in the system panel (not on the top-right corner) while the process was going on in the terminal. But then it was such a mess (no more icons on the right corner amongst other things), and the process wouldn't complete: so I had to reboot the computer and get unity as before, still no date&time and privacy. Thanks for any help. nic

• How can I make sure my website will be available during a presentation?

  - by johnny_s

  I have an online presentation to do next week and I have it all ready to go. The website is HTML and CSS only (no DB), and currently resides on my shared hosting account. Now, although my shared hosting is (relatively) reliable, I have noticed that recently they have been making some changes and my website has been unavailable at times. I don't want this to happen to me on the morning of my presentation, so I am asking what is the best way to prepare for such a thing? My domain is www.presentation.mydomain.com and I would like to keep this if possible (even if issues arise). I have been thinking of a few alternatives: Host my site on two different domains or servers (but what about the domain name?) Have a portable XAMPP version on a USB stick (again, domain name?) Possible failover site/location Update: The presentation will be carried out on their laptop, not mine. So I am unable to install any software.

• No Sound from Shared Media

  - by Travis

  I have a shared media folder that I have all of my mp3's in. When I try to play them using Ubuntu, I get no sound, but the media player (Rhythmbox, Exaile, etc) display that they are playing the file, it looks like everything is playing but no sound. I have checked and rechecked the volume levels of the system and each application and I see no issues. If I move a file to the local drive, it plays just fine. I do sound checks while the file is playing and I get audio (front left, front right) from the test but not from the media file that I am playing. Any help would be greatly appreciated.

• I want to record a screencast of a processing sketch

  - by nathanvda

  I have a created a music visualisation using Processing. I now want to convert that to a video, and the least obtrusive way I could think of is to record a screencast. I figured exporting Processing to video including audio, from within Processing itself, on ubuntu seemed an unsolved issue. Very hard and also could cause timing sync issues (since the music keeps running while images are captured). So move on to the screencast method. Dead-easy, I figured. But I was wrong. First hurdle was to find a way to record the sound from the audio (and not the mic). I did find a tutorial for that here. In short: use gtk-recordmydesktop and pulse audio. But, apparently, what happens: Processing does not use ALSA. When the sound is playing, it does not appear in the Pulse Audio mixer. How can I record the audio now?

• building a website

  - by Ant

  A couple of my friends run a business and they asked me to build them a public website. It will only be used for information about the company with soe pictures. No transactions will be involved. Right now I work for a company where I build internal websites, and do alot of backend programming in C#. I understand html, css, jquery, etc. so I feel like I am completely capable of building a website for them. However, I do not know all the basic knowledge to building one. For example, where should we host the files, what type of security issues do I need to be aware of, what's the best software to use for developing websites (I use visual studio at work), where can I find some design techniques, etc. Any help is appreciated.

• Event Handling in jQuery

  - by bipinjoshi

  In the previous part of this series I discussed how HTML DOM can be manipulated using jQuery. Now let's proceed with one of the most common task you do in JavaScript - handling events. jQuery streamlines the JavaScript event handling mechanism by providing you a uniform and easy way to wire events with their handlers without bothering about the cross browser issues. As an example we will create a custom context menu (shortcut menu or right click menu) that displays some options specific to our website instead of the normal context menu of the browser.http://www.bipinjoshi.net/articles/fc9bf7fb-4b81-48cf-9b2d-cee10d2de2f9.aspx

• How to install CUPS 1.6.3 on Ubuntu 13.04

  - by chmike

  We have a CUPS server 1.3 and my freshly installed Ubuntu 13.04 PC has CUPS client 1.6.2. They are incompatible. On the CUPS web server I saw that CUPS 1.6.3 has fixed the issue. "CUPS 1.6.3 fixes some compatibility issues with servers running CUPS 1.3.12 or older..." So I would like to replace CUPS 1.6.2 with 1.6.3 on my Ubuntu 13.04 PC. I guess Ubuntu 13.10 will have CUPS 1.6.3 and later I would like to upgrade from 13.04 to 13.10. I would thus prefer avoiding installing CUPS 1.6.3 manually to avoid any troubles. Is there a way to install CUPS version 1.6.3 using a ppa or something like that ?

• Problems about responsiveness and keyboard/mousepad not working

  - by ChrisTheNoob

  So I installed Ubuntu 12.04, I'm very new at this and want to get into the world of Linux but have run into nothing but problems. I have an Acer Aspire 5553g. First off, my keyboard won't work. Second, my computer has more than enough of everything to run Ubuntu smoothly, but everything runs extremely slow. (You move the mouse and it gets there a few seconds later) It's to the point where I can't even use it and I really want to. I'm tired of Microsoft stuff and I've been looking at learning how to use Linux based operating systems for a while. Please send me some help to fix these issues and maybe some tips to help get me started. Thanks in advance chris

• Unity: Assigning String value in inspector

  - by Marc Pilgaard

  I got an issue with Unity I can't seem to comprehend, and it is possibly very simple: I am trying to write a simple piece of code in JavaScript where a button toggles the activation of a shield, by dragging a prefab with Resources.load("ActivateShieldPreFab") and destroying it again (Haven't implemented that yet). I wish to assign this button through the inspector, so I have created a string variable which appears as intended in the inspector. Though it doesn't seem to register the inspector input, even though I changed the value through the inspector. It only provides the error: "Input Key named: is unknown" When the button name is assigned within the code, there is no issues. Code as follows: var ShieldOn = false; var stringbutton : String; function Start(){ } function Update () { if(Input.GetKey(stringbutton) && ShieldOn != true) { Instantiate(Resources.load("ActivateShieldPreFab"), Vector3 (0, 0, 0), Quaternion.identity); ShieldOn = true; } } Hope somebody can help, in advance... Thanks

• AGPL License - does it apply in this scenario?

  - by user1645310

  There is an AGPLv3 based software (Client) that makes web service calls (using SOAP) to another software (Server - commercial, cloud based). There is no common code or any connection whatsoever between these two except for the web service calls being made. My questions - Does the Server need to be AGPL too? I guess not - but would like to confirm. Let us say the end point URL for the Server can be configured on the Client side (by editing an XML file) to connect it to different Servers (again, there is no connection other than the webservice calls being made) does it require any of these Servers being AGPL? Are there any issues in running the Client as a DLL that is loaded by other commercial applications on users' desktops? Does it require these other applications also to be AGPL?

• Administrator user session only shows a terminal

  - by Saariko

  Weird problem: After upgrading to 11.10 (and I am sure that I worked with it for couple of days). We had a power failure, and now, when open the computer, what I get is a screen, with a scrollable list of users (administrator is one of them). When I select the administrator user, and login, I get on the top left a terminal window. That's it ! I don't see my regular ubuntu desktop. What's wrong? I have tried some of the issues mentioned here: Delete the .Xauthority sudo apt-get update *I had some DNS errors, so had to fic my /etc/resolv.config (works now) please advise.

• No sound, even though devices appear OK

  - by Felix

  I have a weird problem. Sound used to work until a couple of days ago, but now the builtin speakers in my ThinkPad W520 have stopped working. This happened after either: An update Using the headphone jack in my laptop dock (I had used the jack in the actual laptop before without issues) As I was saying, the speakers do not work at all. Sometimes I get a clicking sound from the laptop, which I assume is the system beep. This does not happen consistently. If I plug headphones in the laptop, I do get sound in them. I have tried playing with all the possible settings both in gnome and using alsamixer. Some screens: What could I try next?

• Anyone code at a treadmill desk? [closed]

  - by Sequenzia

  have been thinking about getting a treadmill desk for awhile now but I just don't know if it is possible to code at one. I can see doing a normal computer job while walking very slow but I just don't know if you can write code do it. Like a lot of people I could stand to lose weight and I am just not in shape anymore. I sit at my computer for at least 12 hours a day and then I am on my laptop for a few more hours. I need to do something to help my health. I also have been seeing a lot of reports about the long term health issues related to desk jobs. Like this. Before I drop a few hundred dollars on a new desk I am wondering if anyone has tried a treadmill desk and if so which one?

• Skype 4.2 crashes and bugs on 13.10

  - by Juhani Taylor

  I've installed Skype and it appears to work fine right up until the point where I try to call someone. If I try to video call someone then the programme freezes and I have to force quit. I've tried several 'solutions' I've found on various forums but none seem to work. Now, when I try to call the Echo service as a test to see if the bug's fixed, it seems to connect and start the non-video call, except that it's completely silent. No audio at all. Any help? It seems to be 2 separate issues: audio and generic crashing. Anyone come across these and found solutions?

• Question about metacity issue from previous post

  - by Alex Poulos

  Yesterday I had an issue with my 12.04 - 12.04 Does anyone know how to fix this? all of a sudden - my Terminal shortcut doesnt work and windows only appear in top left corner and some configuration causing an issue with metacity making it crash - I was walked through the problem, and found out that by creating another user account and logging onto it - the problem wasn't present anymore on that account but still was present on my old account. So my question is - was the problem just something in my old Home folder? - also - can most issues that occur like this be solved by making a new account and backing up the "Home" folder?

• Launcher disappears when Focuswriter is minimized

  - by Andreas

  This bug has to do with the integration of the full-screen writing app Focuswriter within Unity. It appeared before I upgraded from Ubuntu 12.04 to 12.10 - probably caused by a an automatically upgraded change that persist in 12.10: When I minimize Focuswriter after it has been in full-screen mode the launcher is invisible - instead of seeing it I just see a rectangle the color of my desktop background where it should have been. The launcher becomes visible if I click the area once but then I'm likely to hit an icon and unwillingly open a program. I've reported the bug to the developer of the program here: https://github.com/gottcode/focuswriter/issues/101 He has labeled the bug "upstream" saying that the bug is can only be fixed in Unity. My questions are: 1) does anyone (perhaps experiencing problems with other full-screen programs) have a solution or workaround so the launcher won't disappear? 2) where can I file a bug report for this problem?

• Why is better to use external JavaScript or libraries ; and is it prefered to use jquery meaning more security?

  - by shareef

  I read this article Unobtrusive JavaScript with jQuery and I noticed these points in the slide page 11 some companies strip JavaScript at the firewall some run the NoScript Firefox extension to protect themselves from common XSS and CSRF attacks many mobile devices ignore JavaScript entirely screen readers do execute JavaScript but accessibility issues mean you may not want them to I did not understand the fourth point. What does it mean? I need your comment and responses on these points. Is not using JavaScript and switching to libraries like jQuery worth it? UPDATE 1 : whats the meaning of Unobtrusive JavaScript with jQuery ? and yes it does not say we should use libraries but we should have them on external files for that reason i asked my question.

• Sharing a mounted Truecrypt volume via Samba

  - by user10492

  Been banging my head against the wall on this one for a while. I have an encrypted (via truecrypt) partition on a drive. In windows, I mount it locally and share it on my local network. I'm trying to do the same in Ubuntu 10.10 but am running into permission issues. The tc volume has funny permissions and I just can't seem to figure out a way to access it (unsecurely of course) over my network. Other non-tc volume shares work just fine. To recap, I mount a truecrypt volume in Ubuntu and set up a samba share as normal. The share shows up on my local network but accessing it gives 'permission denied'. Mounting as a network drive using a password does not seem to work either. Any insight would be greatly appreciated.

• How to fix Bluetooth Sound in Ubuntu 11.10

  - by Cerin

  Bluetooth sound worked perfectly for me in Ubuntu 10.04. I recently upgraded to 11.10, and although sound in general works fine, Bluetooth sound almost never works. My headset is paired, and Sound Settings shows it's selected as the output device, but no sound is being output. I've tested the headset with other devices, and confirmed it still works, so the issue is definitely with 11.10. I'm not seeing any explicit errors and I can't find any similar issues with 11.10 through Google. I tried restarting the bluetooth service, but that had no effect. What can I do to fix this?

Hopefully this will be the start of a renewed posting binge! A piece of advice, if you are searching for a solution to an issue, or a recommendation, or anything else on the web, when you find a post or a forum thread do 2 things.  First, check the date on the post of thread. If it is older it may no longer be fully up to date and or inaccurate. Bear that in mind.  Second, READ THE COMMENTS! Often small omissions or other issues in the post itself are resolved in the comments. If the solution to your issue does not appear to work check the comments. There may be a step missing or something else relavent that was raised by a prior reader or the author themselves. Cheers, Robert Porter
