  • Is dual booting ubuntu and fedora/openSUSE as easy as popping in a liveCD?

    - by user25757
    I wish to dual boot ubuntu (currently installed) with fedora and/or openSUSE (fedora for vanilla gnome and SUSE for a good KDE experience). I do not know much about dual booting and grub. Do I only have to put in the liveCD and install side by side? Or do I have to partition and stuff? Also, is there an easy way to remove one if I do not want it? Please note that I do not want them on the same /home partition, I want them to have a different one each. (and also if there is a way that is mostly graphical and user friendly, it would be most appreciated)

  • Lenovo ThinkPad T400 and docking station

    - by hari
    Developer in me woke up this morning and asked me to fix this before Christmas. (As his Christmas gift). So, if I power on the laptop after docking it, everything works fine. But if I am working on it standalone and then try to dock it, I cannot get the display. Same way, if I undock it while working, I loose the display. Basically, I need to reboot for any docking/undocking dance to work. Questions: 1) What kind of information should I be looking for to understand the problem? 2) Where to find that information. After this, I can go and try to figure out what is going wrong.

  • ubuntu 11.10 foreman error

    - by user1060759
    Like this post I am also trying to complete this heroku tutorial I have installed and used everything (node.js, npm, express) successfully until I got to Foreman. I installed Foreman by first installing Ruby: alex@ubuntu:~$ sudo apt-get install ruby1.9.1 then installing Foreman. I am a newbie to Unix so I "sudo" perhaps unnecessarily here, but I got confirmation in the terminal that it had installed but also some errors: alex@ubuntu:~/NodeHelloWorld$ sudo gem install foreman Invalid gemspec in [/var/lib/gems/1.8/specifications/foreman-0.26.1.gemspec]: invalid date format in specification: "2011-11-10 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/term-ansicolor-1.0.7.gemspec]: invalid date format in specification: "2011-10-13 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/foreman-0.26.1.gemspec]: invalid date format in specification: "2011-11-10 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/term-ansicolor-1.0.7.gemspec]: invalid date format in specification: "2011-10-13 00:00:00.000000000Z" Successfully installed term-ansicolor-1.0.7 Successfully installed foreman-0.26.1 Then when I try to start foreman I get similar: alex@ubuntu:~/NodeHelloWorld$ foreman start Invalid gemspec in [/var/lib/gems/1.8/specifications/foreman-0.26.1.gemspec]: invalid date format in specification: "2011-11-10 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/term-ansicolor-1.0.7.gemspec]: invalid date format in specification: "2011-10-13 00:00:00.000000000Z" /usr/lib/ruby/vendor_ruby/1.8/rubygems.rb:926:in `report_activate_error': Could not find RubyGem foreman (>= 0) (Gem::LoadError) from /usr/lib/ruby/vendor_ruby/1.8/rubygems.rb:244:in `activate_dep' from /usr/lib/ruby/vendor_ruby/1.8/rubygems.rb:236:in `activate' from /usr/lib/ruby/vendor_ruby/1.8/rubygems.rb:1307:in `gem' from /usr/local/bin/foreman:18 Can anyone help me? I am a newbie to Unix after finally dumping windows as I found I could not get foreman-windows to work for me either I have found this post from someone with apparently the same issue.

  • Wireless with WEP extremely slow on an Acer Timeline 4810T with a Centrino Wireless-N 1000

    - by noq38
    I've upgraded an Acer Timeline 4810T to Ubuntu 11.10. Everything works fine except for the darn wireless interface (network manager). I just tested the wireless interface over a non-encrypted signal and it works beautifully. The issue is definitely related to WEP. Unfortunately, some of the networks I need to connect to are WEP encrypted, therefore this is a serious issue for me that is preventing me from using Ubuntu on my laptop. This was no problem in 11.04 and prior. Is there a simple solution for this? Any suggestions? Here's more hardware information. Hopefully this helps to debug the network issue: sudo lshw -class network *-network description: Wireless interface product: Centrino Wireless-N 1000 vendor: Intel Corporation physical id: 0 bus info: pci@0000:02:00.0 logical name: wlan0 version: 00 serial: 00:1e:64:3c:5e:e0 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlagn driverversion=3.0.0-13-generic-pae firmware=39.31.5.1 build 35138 latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:43 memory:d2400000-d2401fff lspci 02:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000 rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no 1: acer-wireless: Wireless LAN Soft blocked: no Hard blocked: no Many thanks for your help!

  • Installing LBP 2900 printer -> libs folders wrong?

    - by Peter Smit
    I am trying to get my Canon LBP2900 printer to work on Ubuntu 11.10 64 bit. What I have done is try to follow the steps on https://help.ubuntu.com/community/CanonCaptDrv190 So I downloaded the version 2.3 driver and tried to convert the rpm files to debian and installed them sudo alien cndrvcups-capt-2.30-1.x86_64.rpm cndrvcups-common-2.30-1.x86_64.rpm sudo dpkg -i cndrvcups-capt-2.30-1.x86_64.deb cndrvcups-common-2.30-1.x86_64.deb restarted cups and try to install the printer with lpadmin: sudo service cups restart sudo /usr/sbin/lpadmin -p LBP2900 -m /usr/share/cups/model/CNCUPSLBP2900CAPTK.ppd -v ccp://localhost:59787 -E What I noticed however that on the step with lpadmin it goes wrong with the error: lpadmin: Bad device-uri scheme "ccp" After trying to trace what has gone wrong, I think I nailed it to the fact that dpkg installed a file /usr/lib64/cups/backend/ccp instead of /usr/lib/cups/backend/ccp Checking the original rpm with archive manager shows indeed that /usr/lib and /usr/lib64 are used, with the backend/cpp file only installed in lib64. As I understand correctly, Ubuntu 11.10 uses /usr/lib32 and /usr/lib instead so the files are installed in the wrong place. Is there an automated method of converting the rpm/deb files with the wrong lib structure to one with the right lib structure for ubuntu 11.10? Or am I completely on the wrong track for getting my printer installed?

  • Ubuntu Server available updates

    In Ubuntu 11.04 Server when I would log in via ssh it would tell me how many packages are available for updating in the welcome message. After upgrading to 11.10 I no longer get that information.

  • Change /usr/lib to /usr/lib32 for eclipse to look for *.so files

    - by firen
    I am trying to run eclipse and I am getting: /usr/lib/gio/modules/libgvfsdbus.so: wrong ELF class: ELFCLASS64 Failed to load module: /usr/lib/gio/modules/libgvfsdbus.so I already found out that it is because this library is 64bits. I have found 32bit version of it and putted in subdirectory of /usr/lib32 but eclipse do not want to look for it there. How can I make it to look for libraries in /usr/lib32?

  • "SASL authentication failed" with mutt and Gmail, why?

    - by hhh
    I am confused by this, I have installed a lot of new pkgs and followed some tutorials after googling but I keep getting this kind of SASL -err. I am not sure whether the mistake is in some Gmail settings or should I check some settings in Ubuntu? I thought this tutorial here would have solved this problem (i am simply trying to set up local mail reading with mutt, using gmail) but I cannot see the instructed things with telnet: "250-STARTTLS 250-AUTH PLAIN LOGIN" so that is why it is not working. $cat .muttrc set imap_user = "[email protected]" set imap_pass = "pass" #set smtp_url = "smtp://[email protected]:465/" set smtp_url = "smtp://[email protected]:587/" set smtp_pass = "pass" set from = "[email protected]" set realname = "name" set folder = "imaps://imap.gmail.com:993" set spoolfile = "+INBOX" set postponed="+[Gmail]/Drafts" set move = no

  • How can I make Ubuntu One work on windows? It says "File Sync starting..." forever

    - by morph
    I'm using Ubuntu One 2.0.1 on Windows 7 64-bit, and I want to sync my files but the application refuses to. It says "File Sync starting" forever. I left it from morning to evening and it's still the same. Also, I tried reinstalling and deleting registry files then installing again but this didn't help. Im sharing my Pictures, Music and Documents folders. In Ubuntu, sync is working ok. I searched Google and found many people having same problem without a solution.

  • How can I add a bash script to the Unity launcher?

    - by hippyjim
    I open my favourite IDE (PhpStorm) using a custom bash script. I would like to add the script to the Unity launcher. I thought I could add it by clicking the "keep in launcher" option, and sure enough, the icon stays on the launcher after I close the app. But clicking the icon doesn't reopen the IDE - the launcher just sits there, flashing. When I relogin in, the launcher icon is gone. Anyone got any ideas how I can make this work?

  • Remove Kernel 3.1

    - by chazdg
    Is there a way to remove kernel 3.1 from Oneiric? I downloaded and upgraded to 3.1 with these instructions: Open the terminal and run these two commands for both 32-bit and 64-bit versions of Ubuntu 11.10/11.04: wget http://kernel.ubuntu.com/~kernel-ppa...241006_all.deb sudo dpkg -i linux-headers-3.1.0-030100_3.1.0-030100.201110241006_all.deb Ubuntu (64-bit) For Ubuntu 11.10/11.04 (64-bit), issue these commands: wget http://kernel.ubuntu.com/~kernel-ppa...1006_amd64.deb sudo dpkg -i linux-headers-3.1.0-030100-generic_3.1.0-030100.201110241006_amd64.deb wget http://kernel.ubuntu.com/~kernel-ppa...1006_amd64.deb sudo dpkg -i linux-image-3.1.0-030100-generic_3.1.0-030100.201110241006_amd64.deb Everything went well. I was able to reboot quickly, but Firefox and Chrome constantly crash with Kernel 3.1. I am using Gnome 3.2 and saw improvement with 3.0.0.13 provided by ppa. Any help with 3.1 or just removing it would be helpful. Thanks to all that reply.

  • Help making TP-Link Wireless USB Adapter TL-WN723N work consistently

    - by Savvas Katseas
    I've only recently made the jump to Ubuntu, using 11.10/64 as my only desktop OS. Everything seems to be working fine, except my USB Wireless adapter, TP-Link's TL-WN723N which is randomly connecting and disconnecting. The connection time appears to be random, too: I've experienced hours of connectivity and lots of connections/disconnections. I've tried searching for a solution, but what I find doesn't concern this specific USB adapter. I'd like some help identifying the problem... I've also recently switched to using a D-Link router as a wireless hub, which creates its own wireless/n network. Unfortunately this didn't solve my problems, as the new n network can be joined, but there's no connectivity to the internet. I know that's not much info to help others solve my problem, so please let me know of what else I can provide to make this a better question -- and possibly help others facing similar trouble. lsusb reports that I'm using Realtek Semiconductor Corp. RTL8188SU 802.11n WLAN Adapter

  • Google shows subdomain of main site instead of add on domain URL

    - by Welsher
    I have my host (lunarpages) set up with a few add on domains to my main account. These show up as sub-domains of my main account, but they can be reached by using the new domain I've created. So: subdomain1.domain.com -- www.mynewsite.com subdomain2.domain.com -- www.myothersite.com etc. The problem is, mynewsite.com shows up in google with that domain, but myothersite.com shows up with subdomain2.domain.com. I don't have a clue what might be causing this to happen. If anyone has an advice or can point me in the right direction, I'd really appreciate it! Thanks.

  • Simple blogging software (WP replacement)

    - by jontes
    I'm sorry if this is not the right place to ask this question, but I think it's certainly better than at stackoverflow.com. I'm planning to redesign my website and looking for a WordPress replacement for my blog. My requirements are: simple (I won't do a large, complicated website) and lucid well coded (OOP), extensions, templates, active development (not 3 years old) nice but temperate text editor (+images, links), tags and categories, page break easy integration with Flickr, Picasa and social networks technology: PHP and MySQL, not cloud service (like Posterous or Tumblr) Could you recommend me some blogging software which would meet these criteria?

  • My Sites Were Hacked. What To Do?

    - by Vad
    I host multiple domains with this very popular hosting provider and I just went into one of my sites and... I see a black page with message "Hacked by...". I checked and all my sites with the provider are showing this same page. Inside of file system I have seen the hacker placed all default.* and index.* files with this message. So the hacker overwrote all index pages, placed new pages and that is under every, I say again, every folder. Cleaning this up will be close to a most horrible job. What to do (right now I am awaiting the restore of files from hosting provider)? How to prevent this? Whom to blame?

  • How to prevent Google Website Optimizer from making Google Analytics spike Direct Traffic and lower Bounce Rate?

    - by Scott
    I am using Google Website Optimizer (GWO) and Google Analytics. Whenever a person (Google Website Optimizer) does a javascript redirect, Google Analytics will change the referrer. When the referrer changes, the traffic source becomes yourself and is changed to Direct Traffic. For Example: A visitor goes to google: searches for my great service. Clicks the link that goes to website page: /home/ At this point, Google Analytics tracks the referrer as Google. However, /home/ has a GWO javacript redirect to a battery of A/B tests. /home-1/ or /home-2/ or /home-3/ When the redirect from /home/ occurs to /home-1/, google analytics on the /home-1/ page now thinks the referrer is yourself and converts the referrer to Direct Traffic since the Direct Traffic bucket is the unknown. I'm really surprised that GWO and GA do this when they both come from google. Now, How does one fix this to prevent the overwrite of the referrer using GWO?

  • Is it possible to force a tab/window to take focus without an alert()? [migrated]

    - by Chris Brandt
    I've been working to solve some form / session timeout issues on our site. I'd like to get the users attention BEFORE this happens so that they don't lose data that they've entered into long forms. I'm using jquery's .get to confirm with my server when the users session is set to timeout, and warn them 5 minutes before then. I've found that if I pop an alert(), it will bring the focus back to that tab / page -- but this seems 'heavy handed'. Is there a better way to do this?

  • Collisions not working as intended

    - by Stan
    I'm making a game, it's a terraria-like game, with 20x20 blocks, and you can place and remove those blocks. Now, I am trying to write collisions, but it isn't working as I want, the collision succesfully stops the player from going through the ground, but, when I press a key like A + S, that means if I walk down and left (Noclip is on atm), my player will go into the ground, bug up, and exit the ground somewhere else in the level. I made a video of it. The red text means which buttons I am pressing. http://www.youtube.com/watch?v=mo4frZyNwOs You see, if I press A and S together, I go into the ground. Here is my collision code: Vector2 collisionDist, normal; private bool IsColliding(Rectangle body1, Rectangle body2) { normal = Vector2.Zero; Vector2 body1Centre = new Vector2(body1.X + (body1.Width / 2), body1.Y + (body1.Height / 2)); Vector2 body2Centre = new Vector2(body2.X + (body2.Width / 2), body2.Y + (body2.Height / 2)); Vector2 distance, absDistance; float xMag, yMag; distance = body1Centre - body2Centre; float xAdd = ((body1.Width) + (body2.Width)) / 2.0f; float yAdd = ((body1.Height) + (body2.Height)) / 2.0f; absDistance.X = (distance.X < 0) ? -distance.X : distance.X; absDistance.Y = (distance.Y < 0) ? -distance.Y : distance.Y; if (!((absDistance.X < xAdd) && (absDistance.Y < yAdd))) return false; xMag = xAdd - absDistance.X; yMag = yAdd - absDistance.Y; if (xMag < yMag) normal.X = (distance.X > 0) ? xMag : -xMag; else normal.Y = (distance.Y > 0) ? yMag : -yMag; return true; } private void PlayerCollisions() { foreach (Block blocks in allTiles) { collisionDist = Vector2.Zero; if (blocks.Texture != airTile && blocks.Texture != stoneDarkTexture && blocks.Texture != stoneDarkTextureSelected && blocks.Texture != airTileSelected && blocks.Texture != doorTexture && blocks.Texture != doorTextureSelected) { if (IsColliding(player.plyRect, blocks.tileRect)) { if (normal.Length() > collisionDist.Length()) { collisionDist = normal; } player.Position.X += collisionDist.X; player.Position.Y += collisionDist.Y; break; } } } } I got PlayerCollisions() running in my Update method. As you can see it works partly, but if it runs perfectly, it would be awesome, though I have no idea how to fix this problem. Help would be greatly appreciated. EDIT: If I remove the break; it works partly, then it is just the thing that it spasms when it hits two or more blocks at once, like, if I touch 2/3 blocks at once, it does twice the force up. How can I make it so that it only does the force for one block, so it stays correct, and does not spasm? Thanks.

  • WiX installer for XNA 4.0 game?

    - by Mathias Lykkegaard Lorenzen
    I'm trying to make a quick installer for my XNA 4.0 game which should be able to install silently. I did some research and figured out that WiX would probably be best for me. I don't like the setup projects inbuilt in Visual Studio 2010, and InstallShield LE doesn't have an XNA 4.0 redistributable. So, where can I find resources on how to make a WiX installer for an XNA 4.0 game? I've tried these links, but with no luck. They are targeting a different XNA version, and I want to make sure that a silent install would be supported (while still installing all prerequisites). http://blogs.msdn.com/b/astebner/archive/2008/11/17/9115792.aspx http://xnainstaller.codeplex.com/

  • Unity: Assigning a key to perform an action in the inspector

    - by Marc Pilgaard
    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; } }

  • NullReferenceException when accessing variables in a 2D array in Unity

    - by Syed
    I have made a class including variables in Monodevelop which is: public class GridInfo : MonoBehaviour { public float initPosX; public float initPosY; public bool inUse; public int f; public int g; public int h; public GridInfo parent; public int y,x; } Now I am using its class variable in another class, Map.cs which is: public class Map : MonoBehaviour { public static GridInfo[,] Tile = new GridInfo[17, 23]; void Start() { Tile[0,0].initPosX = initPosX; //Line 49 } } I am not getting any error on runtime, but when I play in unity it is giving me error NullReferenceException: Object reference not set to an instance of an object Map.Start () (at Assets/Scripts/Map.cs:49) I am not inserting this script in any gameobject, as Map.cs will make a GridInfo type array, I have also tried using variables using GetComponent, where is the problem ?
