  • Downgrade a bunch of packages

    - by Manuel
    Maybe you have installed packages from a PPA or an external source (e.g. downloaded a .deb for a package that is available through the Ubuntu repos.). Then you decide to drop these upgraded versions in favour to the official repositories.First step is to remove the entries of the sources.list. Is there a way to downgrade all to the highest available version? I know you can install specific versions with apt-get install [package]=[version] But can you downgrade all?

  • Any spywhere threat due to 3rd party plugins?

    - by DUKE
    I installed the plugin mentioned in the following link and after that, by Ubuntu 12.04 LTS behaves a little strange, particularly keyboard shortcuts are not working as expected. http://www.webupd8.org/2012/03/recoll-lens-full-text-search-unity-lens.html Actual my worry is not about keyboard shortcuts, but are there any spywhere threats by installing 3rd party applications (not through Ubuntu software centre) like that.

  • No output devices in sound settings - therefore, no sound

    - by Kev Quirk
    I've just performed a fresh install of Ubuntu 13.10, and I've noticed that sound isn't working. When I go to sound settings, I can see that there is absolutely no sound devices detected. However, I do have my speakers installed and turned on, plus my machine has an internal speaker as well. I've seen other posts where people mention that they have "Dummy device" listed, this isn't the problem here, the output device section is completely blank. Any help is appreciated. Thanks, Kev

    - by leighman
    I have some simple opencv files which I wanted to compile on 12.04. I have installed all the -dev packages They use: #include <cv.h> #include <highgui.h> at the top of the file. Using g++ `pkg-config --cflags --libs opencv` canny.cpp gives cv.h: No such file or directory pkg-config seems to list /usr/include/opencv but the directory created at install is /usr/include/opencv2 Is this a bug? Any advice?

  • Boot Problem in Asus EEE PC 1015CX

    - by Sâmrat VikrãmAdityá
    I am a newbie to Linux world, although I have previously worked on Ubuntu 11.04 for daily use (Net Access and simple recordings using Audacity). I am not sure, at what level I stand as a newbie. I bought this Asus Eee PC two days back. The model is Asus 1015CX. See the specs here http://www.flipkart.com/asus-1015cx-blk011w-laptop-2nd-gen-atom-dual-core-1gb-320gb-linux/p/itmd8qu4quzu8srr . I created a live USB to install 12.10. The usb booted fine. When I clicked "Try Ubuntu" option, it showed me a black screen with a cursor blinking. I waited for 15 minutes and had to restart using the power button. On clicking the "Install Ubuntu" button, the install process went seamlessly. [I have a Windows7 installed on one of the partitions]. i installed it alongside previous windows installation. The system was then rebooted for the first time. It showed the GRUB menu and I selected the first option Ubuntu. After showing the splash screen for a second, it began showing various messages on a black screen and then it struck on "Stopping Save kernel state message". I had to force shut the system using power button. Sometimes it just gives a blank screen with a cursor blinking and on pressing power button, some messages stating that acpid is doing something and stopping services pops up and the system shuts down. I tried booting with "nomodeset" and other parameters as directed in solution to previous such problems on forums. Also Ctrl+Alt+F1,F2,F3,F4,F5,F6..F12 is not doing anything for me anywhere. At installation, I checked Login automatically option. On booting into recovery several options comes up. Clicking resume just gives me a blank screen with cursor blinking. on dropping to root shell and remounting filesystem as RW, I am able to supply some command that worked for others. startx -- Several messages comes up with last one stating Fatal error: No screen found sudo service lightdm start -- Gives a blank screen with a cursor blinking lspci | grep VGA -- Shows some Intel Integrated Graphic... something I don't remember I had reconfigured xserver-xorg, lightdm, reinstalled ubuntu-desktop, unity. What should I do..?? Will going back to 11.04 work..?? Or I should leave all hopes of running Ubuntu on my netbook. Please help.

  • How can I update Ubuntu if the update servers are blocked?

    - by Yasser Hussain
    I connect to the Internet through my college wifi and for some weird reason they have blocked all Ubuntu updates, so I cannot update Ubuntu through the common "Update Manager" way. So I was wondering if there was some other method to update Ubuntu, maybe manually download each package and then install them or download a DVD image which already has all the packages. I have Ubuntu 11.10 installed currently.

  • zoneminder - fewer events, longer duration?

    - by marvin
    I've got zoneminder 1.25 installed on 12.04 LTS 64 bit, and it's working fine, but seems to capure many events (modect, idle setting) with short durations. Some captures are only seconds apart, and when I watch an event, I don't see the person walk all the way through the room, sometimes it stops with them partway through. How can I make the event captures longer (so there are fewer of them, but they catch everything).

  • XFCE session with GNOME in background

    - by 100rabh
    Hi askUbuntu I recently installed XFCE on my Ubuntu 10.04 and it runs finely but with an issue. Everytime I login into my XFCE session I see the background image of GNOME session and after few seconds it disappears which gives me the impression that XFCE session is running over an already running GNOME session. If that is really the case then it might also be eating into my system's RAM which could be a bug. All helps and suggestions are welcome.

  • Gnome Do does not autostart and save shortcut in 11.10

    - by Matt
    For some reason the autostart of Gnome-Do will not work in 11.10. I've installed Gnome-Do via the Ubuntu Software Center. Then I changed the shortcut to launch Gnome-Do and marked the option to autostart Gnome-Do within Gnome-Do. In order to verify the autostart, I checked whether it's also found in the autostart applications (which it was). However, upon every restart I have to start Gnome-Do manually via the unity launcher and change the shortcut again.

  • Developing add-ins for multiple versions of Office

    - by Pranav
    Do you want to develop an add-in targeting multiple versions of Office? And you have basic questions like “Is it possible to do? ” and “How to do it?” ? Then you came to the right place. Few months back, I got a requirement to developed add-ins for Outlook 2003 and Outlook 2007. The functionality for both the versions is same. A doubt stroked… when the functionality is same, why would I develop two add-ins separately? Why don’t I make a single build for both the versions of Office? Then I started searching for techniques to develop add-ins which works in both (2003 and 2007) and read many articles written by VSTO Experts in their blogs, Official VSTO Blog, MSDN, Forums and what not. Misha Says: Theoretically, you can develop an add-in for multiple versions of Microsoft Office by catering to the lowest common denominator. This means if you use an Excel 2003 add-in template in Visual Studio 2008, you would be able to develop and debug this with Excel 2007. However if you try this, you may meet these error messages: “You cannot debug or run this project, because the required version of the Microsoft Office application is not installed.”, followed by “Unable to start debugging.” You can develop Office 2003 add-in in a system where Office 2007 is installed. The following is the procedure that demonstrates how to update your Visual Studio debugging options to use Microsoft Outlook 2007 to debug an add-in targeting Microsoft Outlook 2003. On the Project menu, click on ProjectName Properties Click on the Debug tab In the Start Action pane, click the Start external program radio button Click the file browser button and navigate to %ProgramFiles%\Microsoft Office\Office12 Choose Outlook.exe and click Open Press F5 to debug your add-in For more details. Go through this article in Misha Shneerson’s Blog. There are some tips and tricks to be followed and the things that one needs to take care while developing add-ins targeting multiple versions of Office in Andrew’s Blog. Have a look at this too. You might find it interesting and useful. http://blogs.msdn.com/andreww/archive/2007/06/15/can-you-build-one-add-in-for-multiple-versions-of-office.aspx Here is an MSDN article on Running Solutions in Different Versions of Microsoft Office http://msdn.microsoft.com/en-us/library/bb772080.aspx Hope this helps!

  • Flash Player Plugin on Firefox will not update on Ubuntu 11.10 32 bit

    - by George
    I am running on Ubuntu 11.10 32 bit, and my flash player plug-in for Firefox is outdated. I must update my plug-in to flash player 11, but I am not able. I have already installed Adobe Flash Player via Ubuntu Software center (As it prompted me to after trying to download from the Adobe site) Without the plug-in updated, videos can not be played from directly on a Facebook page, and I believe that it distorts the video player on Youtube. (Image of player can be seen at imgur.com/gYbFx)
