• Is there any way to downgrade or revert an update to the kernel?

  - by David

  Today I installed the linux 3.9 Kernel update (because I heard it would fix sound through HDMI which I no longer have since installing 13.04). After restarted my computer and logging in my screen has only a desktop, and no dock or tool bar. I tried to reset unity and compiz using guides like this one but nothing happens, even after reboot. Is there any way to downgrade or reset the update? EDIT: Running uname -a in terminal brings up 3.8.0 as my current kernel for some reason.

• Connecting Ubuntu home server to internet via laptop

  - by Gray-Wolfe

  I recently got a spare desktop computer from a relative to play around with and since I've been using Ubuntu for a few years I decided to install Ubuntu Server 12.04 to play around with and learn more. However it doesn't have a wireless card, the wireless adapter had a shipping error and will be awhile, and plugging it into the router is not an option. So I figured I could give it access to the wifi from my laptop(which I switch between Windows and Ubuntu) so I could at least get some things started and set up while I'm waiting for the adapter. However the few guides I can find to do that require a GUI, something lacking on the server version. Could someone tell me how to set this up via the terminal? I would appreciate it.

• Microphone doesn't give any input, yet music does

  - by user52643

  I've tried a few guides but nothing works as of yet. I've tried two microphones, both of which work on my Vista setup but do nothing on Ubuntu. Nothing is on mute both on the Sound utility or Skype (which I'm trying to use my mic for). I've been informed that when my speakers are playing very load, this can be heard on the other end of a call, too. See link for cat /proc/asound/card0/codec#0 results which are apparently relevant... _' N.B. I am noob x

• CS4326/7 sound chipset on Thinkpad 600E

  - by user7120

  OK, I know this has been a problem for a while, and I know by now this really old Pentium II laptop is really really really obsolete. However, I have installed Lubuntu 10.10 on this laptop and things seem to work fine except the sound. Now I've read and gone through a bunch of tutorials and guides to working around this, none of which have worked. I have gone through this Ubuntu bug report and that doesn't work either. The problem I think is that the latest workaround is (understandably) about two Ubuntu versions behind. Now I'm not sure what has changed since then to make that workaround not work, but I would appreciate any help. Thanks

• Ops Center and Oracle Solaris 11

  - by user12609425

  There have been a few questions about Ops Center and S11 recently. People have been trying to discover and update S11 from Enterprise Controllers installed on S10 or Linux, and running into problems, and wondering what the solution is. Well, the solution is that, if you want to be able to discover, monitor, and update S11 OSes, you need to install your Enterprise Controller and at least one Proxy Controller on S11 systems. The Oracle Solaris and Linux install guides both note this in the chapters that cover preparing your environment. Technically, if you have an S11 Proxy Controller you can at least discover, manage, and monitor S11 systems. However, features like the automated installer and the image packaging system (for OS updates) can only be used through Ops Center if your Enterprise Controller is installed on S11 as well.

• Getting Started Quickly

  - by Owen Allen

  If you're interested in using Ops Center, you'll want to get up and running as quickly and effectively as possible. One way to do this would be to work your way through the documentation library - use the Linux or Oracle Solaris install guides, then go through the Feature Guide and Admin Guide to start using the software. They're thorough, but they're a lot of reading. But if you're looking to install a simple deployment quickly, and you don't want to do all of the configuration work right off the bat, you can use the Quick Start Guide. It's a streamlined procedure that runs you through installing a single Enterprise Controller and co-located Proxy Controller, and then shows you how to discover assets quickly. Once you've discovered these assets, it describes how to use the analytics feature to view their performance, and use monitoring to keep track of their statuses and health. You'll have to do some additional configuration to use features like OS provisioning, OS updates, and virtualization, but the Quick Start guide gives you an overview of how to install and start using features quickly.

• game is playing but broken graphics

  - by mewanttux

  I installed Steam on Lubuntu and wanted to play dota2 (it has source engine) and it sayed i need a 3dts driver or something but i installed it alredy. I can start dota now, but when i start a game it is not... displaying correctly. For example when i pick a hero the 3d modell is covered in some kind of a lasershow and the map...... i looked around a bit think it is because of the drivers and i should have mesa 9.

• iOS NSError with global handler

  - by Sebastian Dressler

  I am in the beginning of programming an iOS app. Having read the Apple guides on how to deal with errors, I got the following most important points: Exceptions are for programmers Use NSError for the user Now, NSError is usually passed as out-argument which can then be used inside and has to be checked by the caller. However, I'm asking myself whether it is a good idea to use a global error handler, say a singleton which wraps around NSError and could be used to trigger errors and error handling from within the called function. Is there anything against that method or would it be a bad practice?

• Where can I find some Cocos2dx beginner tutorials?

  - by Skeith

  I have tried to start programing with Cocos2dx but I have no idea where to start and the tutorials are no very not very helpful. What I am looking for is some tutorials/guides on how to begin using cocos2dx for the total beginner. Things like how to setup a project and run it and how to do simple things like draw graphics on the screen, play sounds and get input. I am running on windows 7 and have been told by the Cocos2dx wiki that this may cause problems so if anyone has a solution to this that would also be helpful.

• How to set up a local webDAV server for use with Goodreader on the ipad? [migrated]

  - by confused-about-webdav

  I need to know how to set up a local webDav server on my PC so that goodreader on ipad can automatically sync with it over the local wifi network? I am really a rookie when it comes to setting up a web server and have tried various guides on the internet. I tried setting up a webdav server using IIS and forwarded the required ports and enabled webdav publishing but goodreader can find it in the local wifi network automatically nor is it able to connect even after manually entering the credendtials. So i'll be really greateful if someone who has successfully setup a webdav server for use with goodreader can point me on how to do it?

• Wireless will not work in fresh ubuntu 12.04 lts installation

  - by Taake Manning

  I did a fresh Ubuntu 12.04 install on my Sony Vaio laptop, which worked perfectly with 10.04. Now my wireless won't work. I have read just about every Q&A on the subject and I have tried different solutions, including the official troubleshooting guides. My laptop is equipped with a Intel 5100 wireless device. Ubuntu recognizes the device and it's status is given as connected in nm-tool. I can ping the gateway, my own IP number and localhost. Rfkill shows no soft or hard blocks. Any ideas? I am just a few hours shy of reinstalling good old 10.04! Taake

• Downloading anything is hell and arduous without an application. Care to help out an Ubunt-noob?

  - by FilthyCasual

  Torrent from the Pirate Bay even though I have Tixati installed and working? Asks for an application which I don't have (apturl or something similar?) Trying to get the latest AMD Radeon drivers automatically installed? the main file downloads...but just shows up in a window full of files but idk where to drag them. And PlayOnLinux my one hope for gaming since Steam is buggin out without proper drivers? Can't figure out where to "mount" the DVD version it asks for. I'm so lost. I dove head first into the Linux thing thinking it was wildly superior, and maybe it is, but dang if the simplest things aren't hard to do. Any help appreciated. I've been reading guides and manuals but what I need is human experience most of all.

• How to properly code in Unity? [on hold]

  - by Vincent B.

  I'm fairly new to Unity (yet I touched it and made a few proto with it) and I'd like to know how I'm supposed to work with it. I'm student in programming so I'm used to C/C++ with SDL/SFML, writing code and only using Input/Graphics/Network libs. I followed a few Unity guides and it was way more around drag & drop on scenes and a bit of scripting to activate it all, which disturbed me. So I fond a way to only use one GameObject and use a Singleton to launch code and display stuff (for 2d games at least). At the end of the day I make games not using "Instantiate" or such at all. Is it the right way ? Am I supposed to do this ? How much are your scenes populated (in a professional environment) ? When should I stop coding and start using the editor ?

• Multiple network installs with cached downloads

  - by popey

  I tend to do lots of Ubuntu installs, and I'd like them to be up to date from the moment I do them, and not have to install a bazillion updates as soon as the install finishes. I'd also like to cache those packages somewhere on a machine on my LAN, so I don't re-download all the packages every time. How easy is this to achieve? Is there a guide somewhere to making this happen? Bonus points if I don't have to burn any CDs or use USB sticks! Edit: I have noticed a lot of guides for PXE booting and would be tempted to set this up but every time I find one they seem to be old/outdated and broken. My home server runs 10.04 LTS.

• How to transfer a website hosted online to my Virtual Host

  - by user831740

  I'm doing some work on a webpage, meaning I gotta modify a few things. As a result of this I installed apache and all the things that come associated with it, and also installed Joomla, and I got everything running well. My problem is, I need to make apache run this website locally, so I downloaded the public_html folder from the FTP server on my website, but I have absolutely no idea how to implement the website in order to make it run on apache. I've read a few guides, but they all tell me how to create a new website instead of helping me host a website already done.

• Framework to implement an in game gui editor

  - by momboco

  I need to do an in game gui editor. The game engine has his own widgets elements and I don't want a gui library that substitute it. The most difficult task is the implementation of the functionality that makes usable to artists and designers. Positioning Resize Alignment between some elements Multiselection Relationship between children and parents Add guides Magnet to place elements quickly Use of layers Undo / Redo ... I'm searching a framework or something like, with these functionalities implemented. And a form of append my own engine to make use of it. It would be ideally a mixing between a tool like Photoshop and libRocket ( engine rendering independent ).

• where do you track team Decisions

  - by rerun

  I have been on many development teams and as the team matures decisions about direction are made. These decisions often come back up over and over. Like why don't we fill in this field why didn't we use memcache over a custom solutions. These decisions add up over time and become a significant part of style guides coding standards and unit tests. My question is I have never run into a good way of tracking these decisions or the discovery that went into making them. Does anyone have a best practice.

• Help with off-game tasks

  - by peoro

  I love writing video games for fun, and often do that. I noticed, anyway, that most of the times implementing the gameplay itself doesn't take too much time to me (maybe because I already did that plenty times and know what and how to do for most of the things), but when I try to implement off-game stuff I get lost. By off-game I mean what is not gameplay: menus, cutscenes between levels, world map to choose levels, saving and loading status, managing replays ... Only tried to write a few of these a few times, but always failed; that's why I never really completed and distributed a game. Are these common problems? And where should I start to do this? Where could I find some books/guides about such stuff?
