• It appears you are running a x server NVIDIA Drivers 304.02 Ubuntu 12.04

  - by user93444

  So I went to NVIDIA's site and I saw they had a version with a lot of bug fixes. http://www.geforce.com/drivers/results/49073 and I downloaded it, I ran the .run file rooted. It keeps saying "It appears you are running a x server" I don't have any current NVIDIA driver installed, I tried the nvidia x-config thing but that didn't work. It just says it can't be found. Should I wait until that version gets on Ubuntu's software center? I don't feel like installing their old and bad version of the drivers.

• What is proper way to get specific version of package

  - by Peter

  I am using Ubuntu 14.04 LTS I need to use curl package. But it comes in version 7.35.0 with known SSL bug (already fixed in next version) I either need lower version <= 7.33.0 or higher >= 7.36.0 to make it works, but how can I do it? Do I need to manually install curl? I checked synaptics, "Force Version" feature is greyed out. I also checked apt-cache showpkg curl, there is no other version available. I also tried to add "proposed" repositories, no new curl version either. What should I do? I am thinking about getting .deb package from previous ubuntu release...

• Skype 4.2 crashes and bugs on 13.10

  - by Juhani Taylor

  I've installed Skype and it appears to work fine right up until the point where I try to call someone. If I try to video call someone then the programme freezes and I have to force quit. I've tried several 'solutions' I've found on various forums but none seem to work. Now, when I try to call the Echo service as a test to see if the bug's fixed, it seems to connect and start the non-video call, except that it's completely silent. No audio at all. Any help? It seems to be 2 separate issues: audio and generic crashing. Anyone come across these and found solutions?

• All windows decorations disappear after I maximize any window

  - by korda

  When I maximize some of the windows all decorations disappear (by all, I mean on all windows)... Is that common issue on Unity or I'm just unlucky to have some prone to that bug configuration? Anyone have idea how to fix this? It won't fix after unmaximize. It seems like maximazing window simply crashes window decorator. Decoration isn't displayed for all existing windows and any new ones. Only way I found to fix this is to run compiz --replace (but this ruins current windows placement - all windows end up on same desktop). It happens almost every time I maximize window.

• How do I read my PDFs and watch videos properly again?

  - by asp

  Whenever I watch videos, either online of local via Totem and/or open PDF files using evince. The system gets really, really bogged down. All apps get really slow, menus take forever to display, switching windows gives me time to make a coffee, etc. I have a couple of bug reports open on this, but what do I need to do to really troubleshoot the issue? I've purged Adobe Flash from the system, but YouTube HTML5 videos still have the issue. A bunch of PDFs saved locally trigger the problem. And to (temporarily) remove the slowness, I need to shutdown the computer, breath for a few minutes, then restart. A simple reboot does not do the trick. How can I identify the cause? This only started on 13.04. I've had Ubuntu on this machine for a year without a problem until "upgrading" to 13.04. I am not a programmer, but I suspect an issue with the Intel video driver.

• Dolphin Search Toolbar is missing its text field. How can I get it back?

  - by Ike

  A while ago, my Search Toolbar bar went missing in dolphin. I'm referring to the Search Toolbar found under SettingsToolbars ShownSearch Toolbar. I used to sit at the very top right corner of the window. If the search toolbar is checked for view/unhide, the toolbar looks to activate something, as there is a slight shift in the interface buttons, but the text field is gone from the toolbar. I tried reconfiguring with dpkg, purging and reinstalling, etc. I left it alone as I thought it would be fixed in an update, but today I upgraded dolphin and it's still gone. This appears to be a 4.6 bug or something. Any thoughts?

• Is this fix for Avast Antivirus crashing safe to use?

  - by TmRn

  Well I have installed avast anti virus on Ubuntu 12.04. But after updating, it crashes! So I have made some tweaks like below: Press Ctrl+Alt+T to open the Terminal. When it opens, run the command below. sudo gedit /etc/init.d/rcS Type your password and hit Enter. When the text file opens, add the line: sysctl -w kernel.shmmax=128000000 Make sure the line you added is before: exec /etc/init.d/rc S This is what it should look like: #! /bin/sh # rcS # # Call all S??* scripts in /etc/rcS.d/ in numerical/alphabetical order # sysctl -w kernel.shmmax=128000000 exec /etc/init.d/rc S Save the file. Reboot. My question is: Did I do anything wrong? I mean as I have made some tweaks, will it lower the security of Avast down like viruses do? Please if you are a programmer check this if it contains bug or harmful intentions... Thanks.

• BigDecimal.floatValue versus Float.valueOf

  - by Frank

  Has anybody ever come across this: System.out.println("value of: " + Float.valueOf("3.0f")); // ok, prints 3.0 System.out.println(new BigDecimal("3.0f").floatValue()); // NumberFormatException I would argue that the lack of consistency here is a bug, where BigDecimal(String) doesn't follow the same spec as Float.valueOf() (I checked the JDK doc). I'm using a library that forces me to go through BigDecimal, but it can happen that I have to send "3.0f" there. Is there a known workaround (BigDecimal is inaccessible in a library).

• Ugly LibreOffice font

  - by tuhyk

  I have been experiencing this super annoying bug with fonts in LibreOffice. Please see below screenshot. The spaces between letters are just messed, no matter what font or level of zoom I choose. When I change the zoom level, the spacing is actually changing but still looks very ugly. I have a pretty much default instalation of Ubuntu. I installed a couple of fonts (droid, mscorefonts). I did not change any font settings. Fonts in other applications looks great. When I open the very same text in Google Docs or MS Web Word, it looks perfect. I would appreciate any help concerning this issue. Thanks!

• 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?

• Only one resolution available in Xorg.conf

  - by Kévin Guilbeault

  I recently upgraded to Ubuntu 12.10 and when I try to change my resolution in NVIDIA X server settings, I only get the native one (1600x900). When I had 12.04 installed, all resolutions were available in the drop down list. My goal is to have twinview working again. I used to set my two screens to twinview and clones, using my HDTV resolution (1360x768) which was previously available in 12.04 for my laptop screen too. In 12.10, I tried to install all of the NVIDIA drivers available except the nouveau driver. I tried to add a new mode using Xrandr --newmode / --addmode, but it didn't work; it coudn't detect my output. I'd like to know if this is a known bug and if there's something to do with that. Thanks!

• Cheese Not Working in Ubuntu 11.10

  - by user34305

  When i launch Cheese, nothing launches nor the green light on may laptop webcam glows. I typed cheese in terminal and i got cheese:2293): Gdk-WARNING **: The program 'cheese' received an X Window System error. This probably reflects a bug in the program. The error was 'BadRequest (invalid request code or no such operation)'. (Details: serial 144 error_code 1 request_code 136 minor_code 19) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)

• Comment l'analyse statique moderne peut-elle faciliter la vie des développeurs ? Découvrez la solution de Coverity, utilisée par le CERN

  Webinar : comment l'analyse statique de dernière génération peut-elle faciliter la vie des développeurs ? Découvrez la solution de Coverity, utilisée par le CERN Dans un monde où un bug mineur peut avoir des effets dévastateurs, les outils d'analyse statique d'ancienne génération s'avèrent souvent incapables de détecter les vrais défauts de code, difficiles à identifier. Mais des outils modernes d'analyse statique de code existent, permettent de détecter ces défauts critiques et potentiellement dommageables tôt dans le cycle de développement, permettant ainsi de réduire les coûts, les délais et les risques liés aux erreurs logicielles. Coverity Static Analysis est l'une de...

• Apple, Microsoft et Orange victimes d'un bogue de l'an 2011, avez-vous constaté d'autres dysfonctionnements du même type ?

  Apple, Microsoft et Orange victimes d'un bogue de l'an 2011, avez-vous constaté d'autres dysfonctionnements du même type ? En ce début d'année, plusieurs firmes ont été touchées par des bogues. Il y aura donc eu, d'une certaine manière, un bug de l'an 2011, et ce pour Microsoft, Apple et Orange. Commençons avec les utilisateurs d'Hotmail, le client de messagerie en ligne de l'éditeur de Redmond. Ces derniers ont eu la surprise de découvrir que leurs boîtes de réception était complètement vides le soir du 31 décembre. Les messages archivés et ceux classés dans des dossiers spécifiques avaient également disparus. Le pourcentage d'abonnés au service touchés par ce dysfonctionnement n'a pas été précisé, néanmoins tout serait rentré dan...

• How do you resolve the error "E: Unmet dependencies." ?

  - by Georgios Politis

  I did try apt-get -f install but that didn't work either. The problem appeared after installing a modified version of libapache2-mod-wsgi. I modified the package dependencies because, as you can see from the package details link, it depends on python 3. A version of python is required but not version 3 necessarily and I didn't want to install version 3. There's bug #672901 that describes the problem. So, modifying the package dependencies worked but now that I try to install another package I get the error above. How can I get rid of it?

• Alternatives to voxel-based terrain

  - by Neomex

  Are there any alternatives to voxel based terrains? Such terrain should be fully destructable, allow for arches, overhangs, preserve sharp features where needed and keep consistent topology. Maybe you can explain the problem that makes you ask this question? Voxel based terrain is basically just using a 3D grid of data to store data. There are lots of ways to render that data, but it doesn't get much simpler for storing it. – Byte56 Current isosurface extraction methods aren't most effective/bug-free. Cubical Marching Squares seem to solve most of the issues, however it is a relatively new method and there aren't too many resources about it. (I've found single university paper) Even if we stick to CMS, when we want to add multi-material support, we can either divide surface into multiple meshes, or pass a texture array or texture atlas to shaders, then we are limited to set amount of textures and additionally increase memory-usage alot.

• What is an "integration script" and why would I want one?

  - by ændrük

  When I navigate to Launchpad in Firefox, a pop-up appears: I think, despite its failure to form a coherent question, it's trying to ask me if I want to install an "integration script" called "unity-webapps-launchpad". Sadly, it does not provide me with enough information to make an informed decision, nor does it refer me to a source where I can learn more about it. The top result in my web searches on the topic is my own bug report. While this cyclical phenomenon provides a brief source of amusement, it is ultimately unhelpful. So, once again, I've come to Ask Ubuntu for a nudge in the right direction. What is this thing?

• How do I install on an Acer Aspire M3970?

  - by KillingJoke

  I cannot install Ubuntu 11.04 or 11.10 32 or 64 bit from CD or USB Drive on my machine. I tried to unplug all devices connected to USB, no changes the same thing: [ 15.383691] sd 7:0:0:3: [sdg] Attached SCSI removeable disk. And then the installation or Live image booting does nothing more... Its quite annoying that Ubuntu run on every of my Machines but not on my new PC :( What can I do to get that running? Edit: Fascinating thing I found out, is that the 10.04 LTS seems to work in every way. Why does 11.04 or 11.10 does not... Maybe theres a Bug in the installer ?

• 12.04 - Disable the HUD trigger key [ALT] in Emacs & Terminal

  - by EoghanM

  An answer on How to disable HUD in Unity 2D? points to https://bugs.launchpad.net/unity-2d/+bug/947613 where the ALT key will be made reconfigurable. Apart from emacs usage, I'm reasonably happy with using the ALT key to bring up the HUD. While using emacs though, the ALT key is tapped frequently to invoke commands. Should emacs be special cased with respect to the ALT key? I'm wondering what the situation is with games; surely lots of games repurpose the ALT key for their own use, e.g. to fire a weapon? If so, could the same be applied to Emacs, i.e. prevent the ALT key in emacs from triggering the HUD. Edit: just realized how extensively I use the ALT key in the terminal: a quick tap of ALT+B to move back a word loses focus of the terminal and brings up the HUD. Aghch

• Phone complains that identical GLSL struct definition differs in vert/frag programs

  - by stephelton

  When I provide the following struct definition in linked frag and vert shaders, my phone (Samsung Vibrant / Android 2.2) complains that the definition differs. struct Light { mediump vec3 _position; lowp vec4 _ambient; lowp vec4 _diffuse; lowp vec4 _specular; bool _isDirectional; mediump vec3 _attenuation; // constant, linear, and quadratic components }; uniform Light u_light; I know the struct is identical because its included from another file. These shaders work on a linux implementation and on my Android 3.0 tablet. Both shaders declare "precision mediump float;" The exact error is: Uniform variable u_light type/precision does not match in vertex and fragment shader Am I doing anything wrong here, or is my phone's implementation broken? Any advice (other than file a bug report?)

• Theme sometimes fails to load on some UI elements

  - by Neil

  I have no idea if this error as been seen before or not, I have looked around and found people saying they have errors that sound the same but none of the fixes work, my issue is that sometimes the theme does not load some parts of the UI, (the buttons and icons in this case) but the rest is just fine (window bars e.t.c) so I have no idea what the issue is, it works just fine for the most part but sometimes has this bug, if you restart the system it tends to fix it for some time so its hard to see how it could be a graphic card error, however I am very new to linux systems so I may be missing someting very fundamental here. Thank-you in advance. This image shows my problem

• Ubuntu one sync problem with Windows

  - by user87046

  I installed ubuntu one (ubuntuone-3.0.2b) on my Windows 7 pc. My problem is that it does not sync my files without admin rights. The ubuntu one app gets my username and used space, but then hangs.... Then I run the app as admin and it opens, and works correctly. After I run it as admin for all users (right click properties, run as administrator for all users) then the app will not autostart with windows, but when I open the app manually it works correctly. (the uac promt comes up and I accept) I think it is the UAC promt wich prevents it from autostarting, but I do not know how to work around this. I don't know if it is a bug or a problem with windows 7.
