  • How to eliminate an old Ubuntu partition?

    - by GUI Junkie
    I installed Ubuntu 12.04 64-bit side by side with my previous 11.10 32-bit. As everything is working correctly, I want to eliminate the old partition. According to update-grub: Found Ubuntu 11.10 (11.10) on /dev/sda1 But according to GParted, /dev/sda1 is the boot partition! So, how can I discover which partition should be the boot partition for 12.04? Can I safely eliminate the /dev/sda1? Also, GParted gives /dev/sda5 as file system unknown, it's 2.93Gib and might be the swap partition (just guessing).

  • How do i get this to work? [closed]

    - by user1867842
    This is my code.... it speaks for itself. <?php define("html","<html>"); define("htmlEnd","</html>"); etc... etc... ?> What i'm trying to do is make a wrapper for html's tags so they won't be needed anymore. But i can't get any of the attributes for html elements to be defined in php. This again speaks for itself... i don't know any other way of saying this... i guess how would i make a other mark up language like html without any tags but still keep everything about html is what i'm trying to say.....

  • E-Commerce Website

    - by haargott
    I am planning to create an e-commerce website for users to buy products and services. In this website I want users to register and also participate in something like a browser game, where every user may receive some questions which they have to answer. For each question they successfully answered, they receive points and the number of collected points will decide on which rank they are. Edit 2 Currently I am considering using only HTML, CSS, JavaScript, PHP, SQL to design this e-commerce website. Together with this I was thinking about learning jQuery as it may help me, but I am not sure if I should code everything specifically by myself or just use the library to make it faster. 1) Could you tell me if those languages are sufficient enough for creating such a website described? 2) Could you tell me what kind of free software tools and frameworks are most appropriate to use when creating this e-commerce website?

  • I have reinstalled 12.04 and there is no dual boot option

    - by JuP
    Tonight, I have reinstalled Ubuntu 12.4on Win XP pro machine for a 3rd time. (Uninstalled in between.) Oddly enough, this machine had a dual boot between xp pro & ubuntu for several months before we decided to reinstall everything (because of windows). Have you had any problems with the reboot on XP Pro SP3 with all updates & microsoft essentials? I am not getting a choice of which operating system to boot into, it just boots into windows & does not acknowledge ubuntu!

  • Wifi very slow on Ubuntu 12.04 but not on Win7, need help

    - by user84504
    I have an enormous problem: I've a Sony Vaio VGN-NR21S with win7 and Ubuntu 12.04 in dual boot. With Windows everything is fine (except that is windows) but with Ubuntu the wireless connection is awfully slow, basically unusable. I've already search for similar discussion but the solution proposed didn't worked. I've noticed this issue also in live mode both with ubuntu and linux mint. I've installed Ubuntu onto an Acer that shows the same problem when connected via wifi to my router, so I think that maybe the issue is about compatibility with my home router. I really need help, I don't want unistall ubuntu! Please tell me which output u need to help me, thanks.

  • Using Minified Page Specific JS [migrated]

    - by Mike C
    I've been working on a rather large scale project which makes use of a number of different pages with some very specific Javascript for each of them. To lessen load times, I plan to minify it all in to one file before deploying. The problem is this: how should I avoid launching page specific JS on pages which don't require it? So far my best solution has been to wrap each page in some additional container <div id='some_page'> ...everything else... </div> and I extended jQuery so I can do something like this: // If this element exists when the DOM is ready, execute the function $('#some_page').ready(function() { ... }); Which, while kind of cool, just rubs me the wrong way.

  • How do I move my LVM 250 GB root partition to a new 120GB hard disk?

    - by Dennis Schma
    I have the following situation: My current Ubuntu installation is running from an external HDD (250 GB) because I was to lazy to buy an new internal hdd. Now i've got a new internal (120GB) and i want to move everything to the internal. Installing Ubuntu new is out of disscussion because its to peronalized. Luckily (i hope so) the root partition is partitioned with LVM, so i hope i can move the partition to the smaller internal HDD. Is this possible? And where do i find help?

  • SEO - Hidden content before main site content

    - by 0pt1m1z3
    I have a two hidden divs before my main site content, one with the login form and another with the signup form. I then have login and signup buttons within the page that use JQuery to show or hide these divs. I like the effect this setup offers, dropping down from the top of the page and pushing the rest of the content down. However, recently I have been getting serious about SEO and I am wondering if these divs have been affecting my SERP rankings. Basically, every non-logged page (everything bots see) has the same two display:none; divs at the top of the document flow. Is it bad? Should I re-engineer these forms and the way they are displayed?

  • Ubuntu Crashes @ Login Screen

    - by Peter
    So, I've been having troubles with the newest Windows Installer for Ubuntu Desktop(http://www.ubuntu.com/download/desktop/windows-installer). When I start up up the operating system, i enter the login screen of Ubuntu. Everything is fine at that moment except my mouse and keyboard are frozen. Next I hear a "bongo" noise which is obviously the system looping and getting ready to crash. Soon enough, I enter a purple screen with white diagonal short lines in the background. I am then forced to unplug my desktop. Any way to fix this? Thanks!

  • UI font has rendering glitches in GNOME Shell

    - by user353889
    I don't really know how to describe this problem in English. A picture can say more words - look at the tabs at the top of the linked image. The current font settings are shown as well. I don't know what basic info I should provide so if something missing, please tell me. Ubuntu 12.04 GNOME Shell 3.4.1 I know, a reboot can make everything normal but I'm looking for a more permanent solution that can fix this problem (or bug). Update Thanks for Fitoschido, I finally know what keyword I could use for googling. I think it's a bug of gnome shell. https://bugs.archlinux.org/task/34847

  • Is sudo dd taking too long to wipe hard drive?

    - by Adam133718
    I have a 200gb HDD which I removed from a macbook due to several corrupt files in startup. One thing led to another and I decided that I needed to format the drive. I used the command sudo dd if=/dev/zero of=/dev/sdb which is supposed to wipe everything off of the hard drive. It is my understanding that the command writes 0's over every bit on the drive, which I would imagine must take a while. The process has been going for about 18 hours now. I can use other functions of operating system like the web browser and I can even use another terminal window, so I know the system is not frozen. Should I restart the process or let it continue on? Any advice will help. Thanks. By the way, I already noticed a post similar to this that was previously answered though the user was not using the same command as I was.

  • Radeon HD5570 HDMI Video Card 5.1 Audio doesn't work

    - by ryandlf
    I am using Ubuntu and XMBC on my HTPC and have chosen the Radeon HD5570 Video card which has an HDMI output. In the sound preferences there is no surround sound option for the video card just stereo and although I can get sound through it in XBMC, my receiver does not state Dolby Digital on movies that are in fact Dolby so its definitely not giving me the true sound it should. Does this card not support surround sound through HDMI and I somehow missed it? If that is the case does anyone have suggestion that has been tested and works? Id like to know its going to work before investing in yet another video card. UPDATE I purchased a Nvidia GeForce GTS 450, plugged it in, downloaded the proprietary driver from the system control panel, disabled the onboard audio from the BIOS (not sure if this was necessary but I did it anyways), and changed the sound settings to use the new video card. Everything works flawlessly. It was a seemless setup.

  • How can I redirect any kind of access to my site to somewhere else, except for me?

    - by Omega
    My site, www.example.com has a MyBB forum installation, and has many users constantly checking it out. I would like to make a major change to it - basically, I want to delete everything it has and start clean. However, this rebuilding process may take me hours since I need to do a lot of things. Thus, whenever an user tries to enter any part of my site (www.example.com, www.example.com/blog etc), the user will always be redirected to www.example.com/underconstruction so they can see a nice HTML site explaining the current situation. But not only that - while I am configuring my site, I need to visit it myself to make sure things do work live. So basically, it has to redirect everyone who isn't me. Is that possible in any way? I am using GoDaddy hosting.

  • Can't install AMD drivers and Blinking problem

    - by demonscream
    I just installed Ubuntu 12.04 LTS with WUBI, everything is going fine and ubuntu is awesome but i have a little problem. When i open my Sony VAIO model E laptop, i have 2 choices (which is normal) but when i select Ubuntu 1/2 of the time it will just give a rapidly blinkin color background and can only be corrected if i reboot the computer and select ubuntu again. I think this has something to do with the fact i can't get any driver update for my computer from AMD, according to their website, VAIO computers aren't supported. I have a AMD RADEON HD 7650M graphic card which is not detected in ubuntu. When i try to install the drivers using the drivers application it gives a "can't install" error. What should i do?

  • Why do you have to manually type variable names while debugging?

    - by SoboLAN
    I've seen this in a lot of IDEs (even in the most popular and heavily used ones, like Visual Studio): if you want to watch a variable's value, you have to manually type its name in the Watches section of the debugger. Why can't there just be a list of all of them with checkboxes next to them ? The developer can then just check the box next to the one he wants to watch and that's it. Variables with identical names can probably be numbered in some way (for example a, b, x(1), x(2), c, etc. I've seen some exceptions to this (NetBeans or BlueJ), but there are exceptions to everything, right ? Maybe it's a stupid question, maybe not, but I've always wondered why this is so.

  • Game Development Resources? [closed]

    - by stas
    I want to make an iPhone game and I was wondering if somebody could point me to some resources. Before you rage and close this, I am not looking for just a tutorial on programming, I could just google that. I need to find a tutorial on how to actually make a game, as in how to organize your code, what type of methods to run in separate threads, how to manage these threads in a game, etc. I already know everything I need; I can write a physics engine from scratch, I can write a 3D graphics pipeline from scratch, and so on. What I cannot figure out is how to combine all of this knowledge into correctly and efficiently making a game. Obviously for this one would probably go to college, but seeing as I am still in high school, that is not an option. If anyone would know some tutorials or resources, any pointers would be appreciated.

  • Quantal upgrade broke my gnome-shell!

    - by hwjp
    Just updated to quantal 12.10, and Unity works fine, but and I can't get gnome-shell to work :( Some symptoms: when using gdm as the default, it decided to display everything in chinese. When attempting to log in, it accepts the password, and then seems to crash when trying to load my desktop, and seems to restart gdm and send me back to the login screen when switching to lightdm as the window manager, it gets a little further (and in english), bringing up a desktop, but a broken one -- the propeller key doesn't bring up a menu, there's no menubar or notifactions area. i can do a few things, like bring up a terminal with ctrl+alt+t, and launch eg firefox from there, but not much else. I have tried uninstalling gnome-shell, deleting /etc/gdm, and reinstalling Any other suggestions? Which log files to look at for example?

  • 11.04 Wireless is disabled by hardware switch Hp Compaq nc6220

    - by user75711
    Here is some backstory if it is helpful: I had Windows Vista on my computer and I wanted to use wubi to install Ubuntu, everything was fine until I booted into the OS. It said my wireless was disabled by a Hardware Switch. So I booted back into Vista and it disabled there too. I have gotten rid of vista and installed 11.04 instead. It still has this error and as far as I know there is no switch anywhere and the fn keys do nothing. My lshw is: *-network DISABLED description: Wireless Interface product: PRO/Wireless 2915ABG [Calexico2] Network Connection vendor: Intel Corporation physical id: 4 bus info: pci@0000:02:04.0 logical name: eth1 version: 05 serial: 00:15:00:0c:5d:62 width: 32 bits clock: 33MHz capabilities: pm bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver-ipw2200 driverversion=1.2.2kmprq firmware=ABG:9.0.5.27 (Dec 12 2007) latency=64 link=no maxlatency=24 mingnt=3 multicast=yes wireless=IEEE 802.11abg resources: irq:21 memory:d0400000-d0400fff Thanks

  • Configuring httpd.conf to handle wildcard domains and multiple scripts?

    - by Steve
    I have a full-blown site like: http://www.example.com (uses index.php) http://www.example.com/scriptA.php http://www.example.com/scriptB.php I now want to have the possibility of setting up subsites like: http://alpha.example.com http://alpha.example.com/scriptA.php http://alpha.example.com/scriptB.php From http://stackoverflow.com/questions/2844004/subdomain-url-rewriting-and-web-apps/2844033#2844033 , I understand that I have to do: RewriteCond %{HTTP_HOST} ^([^./]+)\.example\.com$ RewriteCond %1 !=www RewriteRule ^ index.php?domain=%1 But what about the other scripts like scriptA and scriptB? How do I tell httpd.conf to handle those properly as well? How can I tell httpd.conf that handle everything after the 'forwardslash', exactly as it does on the main site, but pass a parameter flag like ?domain=alpha (Cross posted at: http://stackoverflow.com/questions/11365566/configuring-httpd-conf-to-handle-wildcard-domains-and-multiple-scripts)

  • Different set of workspaces for each monitor? Ubuntu 13.04 with Unity

    - by Darren
    currently for my new setup, I have a 3 monitor setup. With an NVIDIA Geforce GTX 770(if this matters for this). What I'm wanting to do, is to create a separate set of workspaces for each monitor. For instance: Monitor 1 has a set of 4 workspaces, that are specific to monitor 1, and change independently of the other monitors. Then the other 2 monitors also have their own set of 4 workspaces. So in total I would have 12 workspaces, but each monitor would have it's own set of 4 that work independently from the others. I've read things about Xmonad and Xinerama, but I'm not really sure where to go from here. I haven't ventured to far into different window managers and everything. I'm sure there's not a tool that does this, but if someone could point me in the right direction(I've been using Ubuntu for about 4 years so I can figure some things out on my own too).

  • Gnome/X logs off immediately after login -- which logfiles are relevant?

    - by joebuntu
    I've been tinkering with fingerprint-gui as well as X/xrandr resolution settings. When I start my machine, it boots up normally. As soon as X and gnome have finished starting, it logs me off automatically and brings me back to the gdm login prompt with the user list. Then I am, however, able to log in using "Ubuntu Desktop Fail-safe". I've checked the list of start-up applications, but everything seems fine there. I can't yet put my finger on what exactly might be responsible for this: X, gnome or some messed up pam.d settings. So far I've checked /var/logs/X11/xorg.0.log, /var/logs/auth.log and ~/.xsession-errors. In addition, I don't quite seem to understand the "interplay" between X, GDM, GNOME, GNOME-policykit, PAM.d and all that. Are there any other relevant log files that could point me to what's broken? Specs: Ubuntu 10.10 Maverick Meerkat IBM/Lenovo Thinkpad R60, ATI Radeon x1400 Mobility all updates installed Linux User 1 year+,

  • Would it be more efficient to handle 2D collision detection with polygons, rather than both squares/polygons?

    - by KleptoKat
    I'm working on a 2D game engine and I'm trying to get collision detection as efficient as possible. One thing I've noted is that I have a Rectangle Collision collider, a Shape (polygon) collider and a circle collider. Would it be more efficient (either dev-time wise or runtime wise) to have just one shape collider, rather than have that and everything else? I feel it would optimize my code in the back end, but how much would it affect my game at runtime? Should I be concerned with this at all, as 3D games generally have tens of thousands of polygons?

  • Is there any map maker for javaME game?

    - by user1494517
    For the past two weeks I was trying to make a map maker for my java ME 2D RPG game. I failed because i get errors using slick TWL and the forum for this is inactive. So I just wondered is there anyone that knows slick TWL (Themable Widget Library)? Or maybe do you know a good MapMaker where i could upload my map elements build a map and get numbers to use them for building map with LayerManager class? Already found one http://sourceforge.net/projects/tilemapeditor2d/. But the thing is my map elements are in different .png images. In one of those images there is 16 elements (trees water and etc) and those kind of images are 29. So it would be hard to build a map with LayerManager Well I was thinking putting everything into one image and that way it would be simplier.
