• Domain resolution - local first then external

  - by stefgosselin

  I would like to know how I can configure my dns settings so that domain is resolved locally first, then if not resolved it goes to external DNS. I had this working before, I am using Ubuntu through a VM and need the local domain to resolve first but since I have upgraded I had to reconfigure network and now it works only external, local host file does not seem to even be used. Is there an easy way to check this out? I did slap it up in google but no specific answer seemed to match my case and I too tight on delivery deadline to test-and-try different approaches. You guys rock, thanks.

• Can't interact with windows after first login

  - by evilpie

  Every time I restart my computer and login into my ubuntu account for the first time, I can't click on anything besides the bar on the left. So I can start Firefox from there, but I am not able to click on the new tab button etc. Same will all other apps. I can start the Terminal via the keyboard, but I can't move it around. So I have to logout via the keyboard and login again. Usually everything works fine now. Just waiting doesn't help. The only obvious change I made to Ubuntu was to move the /home directory.

• updating from 8.04 to a newer version?

  - by user175802

  I have an old system. It doesn't have a DVD drive, and I think the cd drive is a bit wonky. The only disk that I have been able to get to install is an old (official) 8.04 Kubuntu disk. No disk that I've burned on a few systems works. They check out, but they don't seem to survive the install (another issue). I thought once I got a version on that I could update over the web, but no luck. It appears EOL. No updates seem to be available, or software to install. Is there a way? I'd like to get it to as new a version as possible. The next step would be to pull the drive and get a new one, but I'd rather not.

• How do I turn off WLAN automatically when LAN is connected?

  - by derroman

  I use my Thinkpad laptop with a docking station. The docking station is connected to my router via LAN. When I walk around the house I use my laptop with WLAN. Is it possible (and how) to manage these devices with a script or something to work like this: If a LAN-Connection is up, the OS should turn off Wifi and if LAN-Connection gets lost (undocking) Wifi should turn on automatically. I use Ubuntu 11.04 64bit with Gnome 2. The system works on an Lenovo ThinkPad R500 with. WLAN-Device: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] LAN-Device: Broadcom Corporation NetLink BCM5787M Gigabit Ethernet PCI Express (rev 02) Any help would be appreciated. Thanks.

• Machine check error on ASUS while booting from USB

  - by user100453

  I put the last Ubuntu iso on my USB stick using UNetBootin, after formatting it to fat32. I've already done that before with other operating systems and it worked. I can't actually boot Ubuntu from USB since I get a black screen with the error "Machine check error" on top the an automatic reboot happens. The error appears right after the boot, I can't see anything else before. I'm using my ASUS X54L latop. Does anybody know how to solve this? Installation from CD/DVD works.

• Sound not working

  - by Jason

  I am new to ubuntu, but really enjoy it. I do have one issue with setting it up on my computer. It is a GoBook XR-1 and everything works perfectly except there is no sound. I've searched and tried everything that I can think of, even uninstalling ubuntu and trying Windows to see if the speakers worked. I found out that it wasn't the speakers or any hardware issues. I tried to download the Realtek drivers, but still no success.

• How to post SEO jobs in the right way and other questions [closed]

  - by mdivk

  I have websites that needs an SEO expert to make them on the top of Google searching result based on some keywords, or at least the first page, the websites are created using common open source platforms (wp, joomla, or magento, zencart) I want to post a job on oDesk but I have no idea on how this particular type of requirement works? what would the guy do on my website? will I be asked to spent extra advertisement money? How do I know s/he really did anything on my site and what have been done? if it's just to optimize URL to make it meaningful then I don't need that, and I am sure giving every page's URL an alias is not enough to make the site popular. Beside, I want to know how much it roughly costs and how long it takes. It would be great if you can shed me some light, thank you in advance.

• ATI ES1000 graphic card

  - by Jorge Biurrun

  I am installing Ubuntu 12.04 on an IBM x3250 M2 server, It has an ATI ES1000 with no acceleration (that does not bother me, we don't need it), we use it to connect remotely via FreeNX. FreeNX works fine, (except than in Windows 7 machines NX Client shows only icons and no text ?!) but the only resolution I can get in the monitor directly attached to the server is 800x600. The display manager also shows me two monitors!, the real one and one IBM 15". Which driver should I install?. It seems that the ATI driver that comes with Ubuntu does not work properly. Any help will be apreciated. Thanks in advance. j&b

• Drag and Drop Team Selection

  - by davidjwest

  I have a Fantasy F1 Website, currently users select their teams using dropdown menus. It works OK but isn't as user friendly as I would like. I would like to implement a drag and drop type of system, there's jQuery code out there that would go part of the way to allowing me to do this: http://jqueryui.com/demos/draggable/ But I am not sure about how to integrate that into PHP and MySQL, my jQuery skills are limited! I'd also need to stop them spending more than a certain amount of money, each driver has a value and the teams can only spend a certain amount of money. There's also limits for example you can only pick a driver once, but you can have three different drivers. Finally, how would you decide that the user had picked their team, I don't want a submit button as that kind of defeats the object of the exercise! Thanks for any advice, I don't expect anyone to write the code for me but some pointers would be greatly appreciated.

• How can I derive force vectors from velocity vectors?

  - by PixelRouter

  I'm making a 2d shooter ala Geometry Wars. I've got my own simple physics at work driving the background grid and all my entities. To move anything in the world I apply a Vector2d force to it. The 'engine' calculates the resulting acceleration and therefore the velocity. I am trying to port some code I found which implements the classic 'Boids' flocking algorithm, but the code I have works by calculating the Boids' velocities directly, so If i use it as is, it bypasses my physics engine. How I can translate the velocity vectors into force vectors that I can apply to the Boids and which will result in the proper velocities via my physics engine.

• Ubuntu crashed while 13.10 was installing and now it doesn't detect my keyboard when I boot

  - by iirelu

  I was running the 13.04 to 13.10 installer, and it slowly caused Ubuntu to break down until eventually the installer itself along with Unity crashed, forcing me to Alt+SysRq+B. Now, when I try to start Ubuntu it doesn't detect my keyboard at all. It boots up completely fine apart from that bringing me to the 13.10 login screen. The backlight on my keyboard remains on but not a single thing works, not even SysRq. I was imagining that if I could run apt-get dist-upgrade it could finish the update, but I couldn't get that far.

• Ubuntu and surround sound

  - by keith

  I'm trying to connect my Logitech x.530 to my Dell studio 1558 and get 5.1 sound. I have 3 jacks and in Windows I automatically could switch between line in adn mic. Which means I could get 5.1 surround over these 3 jacks. Ubuntu does not realise that one of the three jacks should be switched to give sound to the center and LFE speaker. I tried all the tips in the forums, but nothing works. I can only select 4.0 sound in pulse audio. As the dell and the IDT 92hd89e chip for the sound are probably famous laptops I thought there must be someone who has similar issues in the 5.1 sound. I would like to stay at Linux but without this hardware support it's almost impossible.

• Sound Delay With AVAudio Player

  - by Will Youmans

  I'm using the following code in my viewDidLoad to load a sound: NSURL * url = [NSURL fileURLWithPath: [NSString stringWithFormat:@"%@/Moto - Hit Sound.mp3", [[NSBundle mainBundle] resourcePath]]]; NSError * error; hitSoundPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:url error:&error]; hitSoundPlayer.numberOfLoops = 0; Then I'm using this in a void method to play the sound: if(CGRectIntersectsRect(main.frame, enemy1.frame)){ [hitSoundPlayer play]; } This does seem to work, however the first time the sound is played there is a lot of lag and the game stops temporarily. I'm using this same method for when in an IBAction and it works fine, it must be the fact that it's also detecting a collision that makes the sound lag. If I want to be able to play sounds quickly and on the spot without any sort of lag am I doing the right thing? Do I want to use another method? I'm not using any frameworks like cocos2d. If you need to see any more code just ask.

• Unable to change desktop environment in 12.10

  - by LEOXD

  I upgraded to 12.10 some days ago and now I'm unable to change between the environments. I currently have GNOME 3 (with extensions), KDE and, of course, Unity installed. The computer is a Lenovo G550. In the login screen I can get into the menu where the DEs are listed, but I can't select one. I can't use a test account of mine, which used GNOME 3, because after I logged in X crashes/restarts. Unity works, but I can't switch from the broken GNOME 3 to Unity. What did I broke during the upgrade and how can I fix it?

• NetworkManager refuses to manage my WLAN interface

  - by user104167

  I'm using Ubuntu 12.10 with Gnome 3.6 on a brand-new Samsung NP900X4C. The installer detected the wireless adapter, took in the SSID and WPA passphrase, wrote these into /etc/network/interfaces and connected perfectly. Once installation was finished I wanted to switch to using NetworkManager to manage the wireless adapter, since this is much more convenient than fiddling with /etc/network/interfaces every time I find a new hotspot. Therefore I edited /etc/NetworkManager/NetworkManager.conf to set: [ifupdown] managed=true When I rebooted NetworkManager, the problems started: - The NetworkManager tray applet changed from saying device not managed to device not ready - I lost all internet connectivity as wlan0 would not associate to the Access Point - if I set managed=false in NetworkManager.conf and restarted both NetworkManager and networking services from the command-line, the Gnome desktop "semi-crashed" and lost all its Window Decorations, the panel, the launcher and basically became unusable. However if I restart the computer completely after setting managed=false, wlan0 once again works perfectly.

• Having problem to login after upgrading from 11.10 to 12.04

  - by LinuxIsMyFriend

  I just update to 12.04 from 11.10 and I get to the login screen w/o problems. When I enter my password the screen turns black and returns to the login screen half a second later. There is a related question out there which was solved by creating more space on the disk but my disks (or rather partitions) are all below 30%. I can log in as guest. I can also login at the cmd prompt (going to tty with Alt+Ctrl+F1) with my normal user credentials. When logged in as guest I can also install programs using my normal account password. There is the normal authentication error when I mistype my password so I'm also sure the password works. Any suggestions?

• Linux does not connect to wireless network under Hyper-V with Windows 8

  - by Graznarak

  I have a VM I am trying to run under Hyper-V on Windows 8 Pro. I am using an Asus PDE-N15 adapter on the host machine. When I run Windows 8 in the VM it connects to the network and everything works. When I use Linux (Ubuntu 13.04 32-bit, Ubuntu 13.04 64-bit, Fedora, CentOS) it will not connect to the network. When I run ifconfig I see the adapter show up as eth0 with the correct HWaddr. I see that TX bytes 0, and RX bytes == 0. Could anyone help me figure out how to get this to work?

• AHCI, Power Mode S3 and HPET 64bit - please help with these settings!

  - by thetattoo

  my problem is the that for a Hackintosh (unofficial PC running OS X) I needed to set AHCI, Power Mode S3 and HPET 64bit. Now, I want to install Ubuntu (when 12.04 comes out) and was wondering if these settings will be right to use for Ubuntu. I read that AHCI is how the hard disks are accessed, Power Mode S3 is how suspend works with the RAM but couldn't figure out if using HPET 64bit makes any difference than HPET 32bit. What I would like is an explanation of what these BIOS settings do and what is best for Ubuntu. Thank you very much

• jQuery event not working after load

  $(document).ready(function(){ $(function() { $('a.ajaxload').live('click', function(e) { var url = $(this).attr('href'); $('#desktopcontainer').load(url); // load the html response into a DOM element e.preventDefault(); // stop the browser from following the link }); }); $(function() { $(".accordion .accordion-tabs .tab").each(function(){ $(this).click(function(){ if ($(this).hasClass('tab')){ $(this).removeClass('tab'); $(this).addClass('active'); }else{ $(this).removeClass('active'); $(this).addClass('tab'); } $(this).next().slideToggle('slow'); return false; }); }); }); }); My tab works fine but after I click the "a.ajaxload" to add a content to the page, then my tab doesn't respond anymore. Can anyone please tell me where the problem is? Thank you in advance.

• Touchpad stop working

  - by Diegov

  I'm in a HP 430 PC-Notebook using Oneiric. And sometimes my touchpad just stop working :(... I haven't installed anything, just safe playing with terminal following linuxcommand.org BTW my touchpad has a "hole" that in Windows, it works like this: two touch, block touchpad, two touch, unblock. And as far as I now, Ubuntu hasn't recognize this function so I think that the "hole" is not the problem... Also, I'm pretty sure that I haven't touch a little that... PD: Spanish speaker, sorry if "hole" is not the appropriate term haha.. Thanks!

• Wireless mouse temporarily freezes when resume from standby

  - by R Pennese

  I have been getting a very annoying problem since recently in Ubuntu 12.04, probably due to another update that did more bad than good... When I resume from sleep on my Lenovo Thinkpad T420, my wireless laser mouse (Logitech M705) freezes at regular intervals (15.20 seconds) for 5 seconds then works again. This happens regardless if the computer is on battery or on AC power. How do I debug this? I am getting tired of the fact that my system gets more and more unstable over time while it should be the opposite...

• Send some form info to a PHP page to be processed without going to that page? [closed]

  - by zuko

  Okay, so I'm not very familiar with php. I have a very simple form, just 2 text fields. All I want to do is, after validating with JavaScript, send these two string fields in an email to a pre-defined email address. I understand how JavaScript works on the client side; you can respond to user events, etc. And PHP is server-side. What I'm having trouble grasping and figuring out is how do I run PHP functions, etc when I want? I figured out how to use the 'action' attribute of the form to send the data via POST to another PHP page. But this simply opens that page. I don't want to open the page I just want to do some processing and send a message back to the page the user is still on. How do I go about something like that? Thanks.
