• Cannot get laptop wifi to work in ubuntu 12.4

  - by Coda

  Hi i have a Toshiba Satellite L645D-S4106 laptop and i recently installed ubuntu 12.4 on it and i cannot get the wifi to connect for the life of me. When i tried ubuntu out before installing it, the wifi worked while windows was still installed on it. Then i installed ubuntu and now there is no wifi. I can't even flip the wifi network switch to the on position. I installed the driver from realtek for the linux driver and still nothing. Doing rfkill list all shows soft blocked: no and hard blocked: yes. Can anyone help me :p haha very frusterating. It probably is something very dumb. Thanks

• Why does Ubuntu Freezes on ASUS K42DY laptop with RADEON HD6470M Graphics Card?

  - by ix3

  Hi,I have an ASUS K42DY laptop with AMD Phenom II x2, 8 GB Ram , 500 GB Hard Drive and has a didicated ATI RADEON HD 6470M Graphics Card and I'm running Ubuntu 12.04 LTS 64bit on it. I have installed GNOME 3 and also followed this Make Ubuntu look like Mac OS X. I have also installed apps from the software center, getdeb & playdeb all of which worked fine. However, I noticed that Ubuntu freezes after inactivity let's say 1-3hrs. I have already set power setting to never standby or hibernate. This is completely annoying because all I can do is log-out via ctrl+alt+del or manually shut down and reboot my laptop. What should I do? By the way, this happens on all shells Unity, Gnome (even with the basic) and Cairo Dock.I set Swap Space at 8GB during installation. Any help will be appreciated. Thanks!

• More than 2gb of Music without paid plan possible?

  - by user8007

  Hi there, I do not have a paid plan for UbuntuOne and do not intend of buying one, but I do like to buy music from the UbuntuOne Music Store. Is it possible to buy music, once I bought more than 2gb or would I have to move the music out of the UbuntuOne share? In this case, I would suggest to put the music in the official ubuntuone-folder instead of a hidden one. Non-technical users will not understand, why their shared music files are not in this folder, but others are popping up there (e.g. in the webinterface). Best Regards, Lars

• Filling up the empty blocks when the player touches the safe zone again! using cocos2d

  - by user3445020

  Hi guys i am stuck with filling up the data of all the blocks which are empty like the ones in the image. As you can see there i have a pacman like object where i will be moving around. But when you are in the empty space where there are no Blue boxes available i should be able to add new blocks in the path of my pacman and when it touches any other blue boxes like in the below case if my pacman touches the top row of the blue box i should be able to fill all the empty boxed inside the border of the path created by pacman. For now i am using a 2d bool array to store all the filled boxed info like if there is a box inside i am making that cell in an array as true. But how to fill the area with blue boxes after player finishes his path ? Any help would be great thank you. More info about this problem is here: filling the empty spaces in a certain region in a grid using c++ Same problem

• Upgrade Ubuntu 10.04 to Ubuntu 10.10

  - by user8561

  Hi. I'm new to these forums so I'll be quick. When I try to upgrade to Ubuntu 10.10 from 10.04 I get this error, I have tried upgrading from Terminal and Update Manager as well. Could not determine the upgrade An unresolvable problem occurred while calculating the upgrade: E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. This can be caused by: * Upgrading to a pre-release version of Ubuntu * Running the current pre-release version of Ubuntu * Unofficial software packages not provided by Ubuntu If none of this applies, then please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bug report. Restoring original system state Thanks Aborting

  - by Svendbenno

  Hi. I've always had this problems with skype and pulseaudio on ubuntu. Whenever i start up skype, i have to call someone, then hang up 4-5 times, before the other person can hear my voice. When i, or the other person hang up, skype tends to lock up. I can't kill it with "killall skype" or a logout, so i have to restart my computer. Have anyone else encountered this problem, and if so solved this? I'm using 10.10 btw.

• How can I make my generic comparer (IComparer) handle nulls? [closed]

  - by Nick G

  Hi, I'm trying to write a generic object comparer for sorting, but I have noticed it does not handle the instance where one of the values it's comparing is null. When an object is null, I want it to treat it the same as the empty string. I've tried setting the null values to String.Empty but then I get an error of "Object must be of type String" when calling CompareTo() on it. public int Compare(T x, T y) { PropertyInfo propertyInfo = typeof(T).GetProperty(sortExpression); IComparable obj1 = (IComparable)propertyInfo.GetValue(x, null); IComparable obj2 = (IComparable)propertyInfo.GetValue(y, null); if (obj1 == null) obj1 = String.Empty; // This doesn't work! if (obj2 == null) obj2 = String.Empty; // This doesn't work! if (SortDirection == SortDirection.Ascending) return obj1.CompareTo(obj2); else return obj2.CompareTo(obj1); } I'm pretty stuck with this now! Any help would be appreciated.

• Get Compiz working on x1300 ati

  - by wdkrnls

  Hi, I have Ubuntu 10.10 installed on a thinkpad T60 with an ati mobile x1300. Ubuntu isn't loading any proprietary drivers and compiz doesn't work. A google search turned up nothing. Sure, some people reported "bad performance", but I'm not getting any "performance" with compiz and these post were all for previous editions. I'm new to messing with ati drivers. Is there a way to make sure xorg-video-ati is loaded? Do I have to add any voodoo lines somewhere in /etc/X11/? Did anyone else have this problem? Thanks for your help!

• 3D primitive rendering library

  - by tomzx

  Hi, I am looking for a library which would easily allow me to render shapes (cubes, spheres, lines, circles, etc.) in 3D3 and OpenGL if possible. I want to be able to rapidly design visual debugging tools and I am not proefficient enough in graphics rendering to do it myself (writing the low level stuff that is). The library would have to be for C/C++. I've already taken a look at the open-source 3d engine, but I feel those are too big for what I really need. Do any of you know if such library exist? If so, links would be appreciated!

  - by heartcode

  Hi everyone, First of all, Happy New Year! I am thinking about making my blog accessible and enjoyable on mobile devices (as many handsets as possible). I am using Wordpress 3.0.4. What I've found is couple of cool plugins like WPTouch (for touch enabled devices), The Wordpress Mobile Edition and the Wordpress Mobile Pack. I am wondering which one is the best to use if I can use only one. If I can use more or (even all these three) are they compatible? Does anyone have any experiences in this topic? If so I would much appreciate some advices or best practice links. Happy 2011, thanks in advance, Rob

• Need some help fixing fonts (11.04 Alpha 3)

  - by Spacecraft

  Hi I changed my Application Font and Window Font to something much better looking but it has a few problems. The font is Umpush Light. It's doing this in the software center: http://img851.imageshack.us/img851/8307/workspace1004.png If I increase the font size from 11 to 12, that problem goes away, but then everything is too large. When I increase it this also happens: http://img819.imageshack.us/img819/6231/workspace1006e.png It starts moving the text in the search box up, and the "All Applications" drop down gets messed up too. It seems like there is too much padding around the font or something. Anyone have any ideas on how I can fix this?

• Relationship between databases [closed]

  - by user1525474

  Hi I am getting ready to create my first web aplication.I have some knowledge of databases but I have never used databases with relationship created beetween them and also I am not sure how to acces the data in the relationship.My experience is limited to basic CRUD applications and working on simple tables with no realtionship using PHP and MySql. For example I will be creating a login system and for each user I would like to create a profile page that store different data(name , address , profile image etc.).Some of the info will be the same in both tables so there is no point in creating the same table twice. What I would like is if anyone can tell of some tutorials so I can better understand the concept?
