• pointer jumping about Lubuntu 12.04

  - by Gary Kirkpatrick

  Using 12.04 on a Samsung NC110. If I disable Touchpad, the cursor does not jump about while typing. This is very very annoying. Tried this tutorial, but this does not help. The problem occurs even when my fingers are well away from the Touchpad. I wonder if another key or key combination causes this problem? I sure could use some help on this. I have had this problem with various versions of Ubuntu and now Lubuntu.

• Why is the font spacing on some websites broken?

  - by user950731

  I am using Ubuntu 12.04 on a Dell Studio 15 and so far am really impressed. I could not find a solution for my problem by googling. The fonts on some websites do not have proper spacing. they overlap and are very hard to read that way. I am using the Ubuntu standard fonts and have not changed them after installing. Here is a screencap that shows my problem. The problem occurs in Firefox and Chrome the same way, and on the same websites. Thanks for your help. Best regards el

• The field for entering password freeze if no text is enter quickly after i install cinnamon on 12.04

  - by user109162

  Iam a total newbie to Ubuntu . I installed Cinnamon through terminal . The problem is that when i boot up, if i don't enter the password before 1 or 2 minutes the password field will freeze and won't accept any text inputs.The problem was most likely caused by Cinnamon because i guess the problem started after i tried to install some Cinnamon extensions. Please answer in non-technical way as far as possible. I will never go back to Windows whatever be the outcome. Help me stay on to Ubuntu.

• Need a few reboots to connect to wireless

  - by Debajyoti Nandi

  I am running xubuntu 12.10 on my msi wind U100 netbook. I have a problem with the wireless connection. Whether the wireless connects automatically to a known wifi hotspot (both at home and starbucks) is temperamental. Sometimes I need to reboot one or more times to get it connected. Otherwise, it tries and keep asking me to enter the password (which is saved and when it works it does, so the problem is not with the password). Every time my computer awakes up from sleep the same problem. I have to do a reboot to connect to wireless. I searched everywhere but found no solution. I would greatly appreciate if someone has any solution. I will gladly share the hardware/software or config info, if asked, but I don't know exactly what to share and where to find them. Thanks you for any help.

• Print jobs to Epson Stylus Photo 640 all stopped after upgrade 10.04 to 12.04

  - by Tessa Sayers

  Upgraded from Ubuntu 10.04 to 12.04 on 19th oct 2012. Now all print jobs end up in the print queue with the label "Stopped". Reinstalled the printer driver - it is gutenberg 5.2.8 pre1. Looking at "http://localhost:631/jobs" shows an error message by each stopped job as follows:"The PPD version (5.2.5 Simplified) is not compatible with Gutenprint 5.2.8-pre1." Found a long bug-fixing history in bugs.launchpad.net which seem to imply that this problem has been fixed. It seems to be a problem with the installation not updating the ppd files. Is there any workaround to fix this problem?

• Question about metacity issue from previous post

  - by Alex Poulos

  Yesterday I had an issue with my 12.04 - 12.04 Does anyone know how to fix this? all of a sudden - my Terminal shortcut doesnt work and windows only appear in top left corner and some configuration causing an issue with metacity making it crash - I was walked through the problem, and found out that by creating another user account and logging onto it - the problem wasn't present anymore on that account but still was present on my old account. So my question is - was the problem just something in my old Home folder? - also - can most issues that occur like this be solved by making a new account and backing up the "Home" folder?

• Why does the BADSIG/"Untrusted sources" error recur forever?

  - by Jeff McMahan

  On at least a dozen occasions, I've spent 2-3 hours figuring out how to get Ubuntu 11.10-12.10 to either update or acquire software from software center, or both. I want to fix whatever is causing the BADSIG problem once and for all; I've wasted so much time trying to get this to work well enough that I can rely on it, but the same problem comes back after a couple weeks of normal updates and software center usage. Don't refer me to a standard posted solution on the web---whatever it is, I've used it more times than you have. The question isn't whether I can get it to work right this afternoon. I can. The question is what is causing the problem to recur regularly across 3 releases. Notice: I use this computer 4-5 hours per week and I do little on it. PDFs, Latex, FireFox, Mendeley, and that's it. I don't constantly install new software, and I don't fiddle with things unnecessarily.

  - by George

  I have a problem that is not of easy resolution, happen to tell... I have Installed Ubuntu 10.10 Server. I want to join to the system way vga=788, into the grub it changes without any problem editing the file grub.cfg, the problem is that editing the above mentioned file I join to the system way vga=788 (800x600) and then command line puts itself in way vga=792 (1280x1024). Is there any way of changing this configuration so that it is always vga=788? tanks. sorry for my english :D

• What's the point of Rabbit MQ? [duplicate]

  - by bad_boy

  This question already has an answer here: When to use Advanced Message Queuing Protocol like RabbitMQ? [closed] 2 answers First of all, let me say, I have no problem following tutorials. The problem is that I don't understand why even Rabbit MQ is ever needed. And there's no such explanation on tutorials - they only show what to do and how to use, but not when its usage is the case. Can you explain this? Why would you want to use Rabbit MQ? To solve what problem?

• windows system (bootloader) partition accidently deleted during multiple installs

  - by S.Y.T.

  After experimenting with multiple variations of backtrack and xbmcbuntu variations of Ubuntu with dual boot successfully, my windows partition became unrecognizable to grub. I used my windows boot CD to try to correct the problem. However, I deleted all partitions except for the NFTS one that contains my old windows install. (And, merged all other ones into that in hopes of getting back to the windows boot loader and out of grub) Now, all I get is a grub command prompt when I try and boot the system (how??? - I thought I deleted grub) And, now the windows boot disc doesn't even recognize the install. I've tried TRK to try and resolve the problem. Though I must admit ignorance in correctly using this utility. I've searched for other answers to this problem. Any help would be much appreciated. S.Y.

• Blender: Having trouble moving vertices

  - by capcom

  I've been using Blender for two days now, and ran into an issue while following a tutorial. Before anything else, I'd like to show you all what my problem precisely is. Here is a short video I uploaded: click here. I thought it may be easier for you all to help me identify and solve my problem more accurately with a visual aid. I would like to emphasize that this issue began to occur after I extruded that trapezoidal region (misstated as a parallelogram in the video). I decided that I did not want the extruded region, and just hit undo. Ever since then, I began to experience the problem you viewed. Thanks.

• Is there a 'design pattern' type listing of common algorithms?

  - by KevinM1

  Is there a 'design pattern' styled listing of common/popular algorithms anywhere? Specifically, something that has a similar format along the lines of: Algorithm Name: e.g., Quick Sort, Bubble Sort, etc. Problem: A description of the stereotypical problem the algorithm is supposed to address Description: Description of the solution Implementation: Code examples of the solution Big O Rating: Self-explanatory Similar Algorithms: Algorithms that address the same problem in different ways, or similar problems I really like the GoF design pattern listing style, and I think it would help me learn various algorithms better/easier if I could find a resource that was similar in terms of organization.

• Force Xorg to run in specific resolution

  - by Z9iT

  From my past experience (using Win-Xp), this particular monitor works only on 60Hz , Best resolution being 1024*768. I have "installed n configured" Ubuntu 12.04 Minimal (on USB stick) so that most of the time terminal is used, however whenever theirs a need to enter GUI I may issue startx command to go into gnome. However the problem is that on this particular system, issuing this command poses problem for its default refresh rate don't synchronize with the monitor. The display keep on flickering and utterly unreadable. It is visible that gnome has been loaded and default wallpaper and desktop items are visible. But the problem is due to refresh rate different than 60Hz. I am looking for a command attribute to startx command which will force the refresh rate to 60Hz and resolution preferably to 1204*768

• GPG and libpcap help

  - by Johnq

  I was trying to install the newest version of libpcap (as the version in the repositories doesn't seem current) and ran into the following problem. I copied the tcpdump-workers.asc text from the tcpdump website (which hosts libpcap as well) and imported the key to my keyring using gpg --import tcpdump-workers.asc. That when all well and fine but when I tried to verify the libpcap-1.4.0.tar.gz file against the key with gpg --verify, I ended up getting the message that unexpected data. was found. I am wondering if anyone else has run into this problem as the ancient technique of googling my problem has done little to answer my question.

• Acer AO722 flickering screen

  - by user1131702

  The screen on my Acer Aspire One netbook (AO722) flickers for a few minutes when Ubuntu awakens the screen after a period of inactivity. I am pretty sure this is not a hardware issue, as I never see this problem in Windows and both of my Acer netbooks exhibit the same problem. I see the flickering in all recent versions of Ubuntu -- 11.10, 11.04, and 10.10. Surprisingly I haven't been able to find a lot of information about this problem online. I believe the video card in this netbook is Radeon 6290 paired with AMD C-60. I am using the default open source video driver. Would appreciate any tips on how to get rid of the flicker. Thanks!

• Jumping around to work on different features when you get stuck, is it a source of project failures?

  - by codecompleting

  On personal projects (or work), if one gets stuck on a problem, or waiting to figure out a solution to the problem, if you jump to another section of your code, don't you think it will be a good reason your application will be buggy or worse yet never get completed? Assuming you are not using git and code each feature to a specific branch, things can get out of hand since you have 3 different features you are working on, and you have unresolved issues in each. So when you get done to work, you get stressed out because you have these hanging issues and half-baked code lingering about. What's the best way to avoid this problem? (if you have it) I'm guessing using something like git and creating a branch per feature is the safest way to avoid this bad habit. Any other suggestions?

• I can't login to facebook from any browser

  - by user92974

  I'm Using UBUNTU 12.04. I'm having problems with Facebook. It really hard to login. Takes like 3 or 5 min. At first I thought it was a flash problem but then I realized it could be some proxy's conf file. Other sites doesn't have problems. Yesterday I tried Tor-browser-bundle and I installed privoxy using this rules http://www.neilvandyke.org/privoxy-rules/ . Today I removed privoxy and the conf file with the Ubuntu software center and ubuntu-tweak. I don't really find the problem and my windows pc does not have any problem with the same modem. I don't have an ISP'S PROXY it just a direct Internet connection using automatic DHCP. Maybe I am missing something else. But I want to be sure so, I'm asking. PD: Sorry for my English I'm Argentinian.

• Rendering only a part of text FTGL, OpenGL

  - by Mosquito

  I'm using FTGL library to render text in my C++ project. I can easily render text by using: CFontManager::Instance().renderWrappedText(font, lineLength, position, text); Unfortunately there is a situation in which this Button which displays text, is partly hidden because of resizing container in which it is situated. I'm able without any problem to draw Button's background to fit the container, but I've got a problem with doing the same with a text. Is it possible to somehow draw only text for given width and the rest just ignore? This is a screen which presents my problem: As you can see, the Button "Click here" is being drawn properly, but I can't do the same with "Click here" text.

• Redirect from domain to other one

  - by Michal

  I deal with the following problem. I am customer of one domain reseller, which has fair prices, fine administration, and I have all my domains registered by it. Recently I've created a new webpage using a free web service (those sites where you can create a simple webpages with some template after few clicks). This new web page has default address in the following form: "pagename.provider.cz", but I want to use my own domain "pagename.cz". And that is the problem, because the provider would assign domain name to my presentation only if I registered mentioned domain by him. That wouldn't be a problem, but he is three times more expensive then my favorite one. So I am thinking about registering domain "pagename.cz" under my favorite registrator and then making 301 PHP redirect from it to "pagename.provider.cz". Shall this affect (negatively) my domain ranking? Are there any catches which I shoud care about?

• Dell Inspiron N5110 Battery lasts only for 1.5 hours as opposed to 4 hours on Windows 7

  - by ubuntufan

  I've a Dell Inspiron N5110 laptop with the following specs: i5 processor 4 GB RAM NVIDIA GeForce GT540M Ubuntu 12.04LTS My laptop is overheating and the battery is lasting for only about 1.5 hours. I had checked if the battery indicator was problematic but it turned out it wasn't. I drained the battery to it's least possible value and that came to around 1 hr 40 minutes. In fact, I've the same problem with Debian and Xubuntu as well. I would like to get some proper solution for this. FYI: I've been having this problem since Ubuntu 11.04 but I'm not able to solve this in spite of trying various fixes like reducing brightness, Removing startup apps, Updating kernel and what not?. I'm a big fan of Ubuntu but this problem is stopping me from using Ubuntu and I'm using Win7 for 90% of the time.

• Excel duration converts to date

  - by Malcolm Anderson

  I'm working on an Excel 2010 spreadsheet and I'm trying to put in durations for some tasks I want to schedule.The interesting thing is that up until a few minutes ago, I couldn't do it.I was entering in "47:00" and excel was (and still is) converting it to "1/1/1900 23:00:00"In my mind, I want the value to be 47 minutes, but for the life of me I cannot find a fix for this behavior.Here's the weirdest thing, I haven't had this problem in the past.  Usually I put in times, add them up and they work like magic.  Put in 18 entries of 20 minutes each, total them and excel will usually tell me that it's a total of 6 hours.No problem.Today, problem.Here's the weird bit:As I was writing this post, I got it to work.By formatting the column as custom "[hh]:mm" and summing the columns, I can get total times.But the times are still being formatted into dates if I look at the underlying data.  Bottom line, if you need to calculate durations, you can, but don't look too closely at what is happening underneath the covers.

• LXDE will not suspend when laptop lid is closed, and will die when woken up

  - by user46061

  I am not an experienced Linux user, although I have been using Ubuntu occassionally some time already. ( Since Feisty Fawn probably? ). Now I installed Ubuntu 11.10 and it is nice ( well, after I installed LXDE, Unity sucks and I didn't really like gnome-fallback-session ), but it has one problem: After being suspended, when I wake my computer up, it starts up and in about 5 seconds it dies. Like a normal shutdown. Then, when I start it again, the screen stays blank, so I have to hard-turn it off - only then, when I turn it on, it works. It is an MSI laptop, about 3-4 years old. The second problem is: After installing LXDE, when I close the laptop lid, it does not suspend. I can only suspend using the shutdown menu - and the waking up problem remains. Many thanks for your time and advice guys.

• New "How do I ..." series

  - by Maria Colgan

  Over the last year or so the Optimizer development team has presented at a number of conferences and we got a lot of questions that start with "How do I ...". Where people were looking for a specific command or set of steps to fix a problem they had encountered. So we thought it would be a good idea to create a series of small posts that deal with these "How do I" question directly. We will use a simple example each time, that shows exactly what commands and procedures should be used to address a given problem. If you have an interesting "How do I .." question you would like to see us answer on the blog please email me and we will do our best to answer them! Watch out for the first post in this series which addresses the problem of "How do I deal with a third party application that has embedded hints that result in a sub-optimal execution plan in my environment?"

• Layering Design Pattern in Java clean code style

  - by zeraDev

  As a Java developer, I am developing trying to use the clean code rules. But in my team we are facing a concrete problem: We have a business layer offering a service called "createObject", this service makes a lot of operation which can result to problem. E.g: parentObjectDontExist, objectAlreadyExist, dontHaveAuthorizationToCreate, operationFailed... and we want the UI using this service to display different information messages depending which error occurred. In old java dev, we should have create all signed exception type and throw it in createObject. As Clean code says, it is forbidden to use Exception for business logic AND signed exceptions are evil... Why not...But i don't know how to solved this problem and i don't want to use return code. How do you do? Thanks for youre experience return.
