• DockbarX Applet not loading

  - by Nik

  I used to have dockbarX applet installed on my gnome panel. However one day when I login in I got a error message which can be seen in the screenshot below. So I removed it, and then tried adding it again to the gnome panel but I still get the error message. I am running the latest version of dockbarX 0.43 with the helpers enabled and media buttons etc. I did not update it recently and have been using this version for a couple of weeks now and got this problem only now. How can I solve this problem?

• Ubuntu Software Centre Issue (unity 11.10) after broken sun-java6-jre package installation

  - by Stephen Myall

  I have been installing software packages from USC and I am getting the following error message. Worked fine one minute then the message below. Tried to search but couldn't find a solution Previously I was installing the sun-java6-jre package in terminal and had an connection outage and it didnt complete. I attempted an apt-get -f install with no success. i dont know what to try next. I'm relatively new to Linux. The answer provided with a similar question on this site didnt resolve the issue for meClick on this link An unhandlable error occured There seems to be a programming error in aptdaemon, the software that allows you to install/remove software and to perform other package management related tasks.

• GDM locale problems

  - by Simón

  I have two problems with GDM on Ubuntu 10.04. The first is with locales. In my system I have defined: $ cat /etc/environment PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" LANG="es_ES.UTF-8" LANGUAGE="es_ES:es:en_US:en" $ cat /etc/default/locale LANG="es_ES.UTF-8" LANGUAGE="es_ES:es:en_US:en" $ cat /var/lib/locales/supported.d/local es_ES UTF-8 es_ES.UTF-8 UTF-8 en_US UTF-8 en_US.UTF-8 UTF-8 But when I enter in gnome desktop: $ locale LANG=es_ES LANGUAGE=es_ES:es:en_US:en LC_CTYPE="es_ES" LC_NUMERIC="es_ES" LC_TIME="es_ES" LC_COLLATE="es_ES" LC_MONETARY="es_ES" LC_MESSAGES="es_ES" LC_PAPER="es_ES" LC_NAME="es_ES" LC_ADDRESS="es_ES" LC_TELEPHONE="es_ES" LC_MEASUREMENT="es_ES" LC_IDENTIFICATION="es_ES" LC_ALL= I have deleted ~/.dmrc and I have restarted the system but nothing. GDM login screen also doesn't permit change this setting. However, in the text terminals (tty1,...): $ locale LANG=es_ES.UTF-8 LANGUAGE=es_ES:es:en_US:en LC_CTYPE="es_ES.UTF-8" LC_NUMERIC="es_ES.UTF-8" LC_TIME="es_ES.UTF-8" LC_COLLATE="es_ES.UTF-8" LC_MONETARY="es_ES.UTF-8" LC_MESSAGES="es_ES.UTF-8" LC_PAPER="es_ES.UTF-8" LC_NAME="es_ES.UTF-8" LC_ADDRESS="es_ES.UTF-8" LC_TELEPHONE="es_ES.UTF-8" LC_MEASUREMENT="es_ES.UTF-8" LC_IDENTIFICATION="es_ES.UTF-8" LC_ALL= The solution to problem is to edit .drmc file, but I think this isn't the right way. Why doesn't GDM read/apply the system locales? Why don't I see, in GDM login screen, the box to change the locale?

• App installed in ~/usr launches from terminal but not Applications menu (or why does setting ld_library_path in .profile not work as it should)

  - by levesque

  I have built and installed an application under a directory of my choosing, let's say under /home/jim/usr, so files have been put in three-four folders, all under this $HOME/usr folder (e.g., bin, include, lib, share, etc.). I can launch this application from the command line just fine as I added the proper paths to my environement variables PATH and LD_LIBRARY_PATH in ~/.bashrc. I added the same paths to the ~/.profile file, which, if I'm not mistaken, is supposed to be parsed by Ubuntu. Doesn't work. Nothing. Where can I go from there? EDIT: I logged out/in and restarted my computer. Both didn't change a thing. The problem seems to come from the fact that no matter what I do the LD_LIBRARY_PATH environment variable is not properly passed to Ubuntu. Using log files, I found that the application I'm trying to run in this example doesn't find one it's dependencies located in ~/usr/lib. One solution would be to add the /home/jim/usr/lib folder inside a file located in /etc/ld.so.conf.d/, but I don't have admin rights on this machine. Making a wrapper script like this one works: #!/bin/bash export LD_LIBRARY_PATH=$HLOC/usr/lib application &> $HOME/application_messages.log but that would force me to wrap all my home compiled applications with this script. Any ideas? Why does Ubuntu/Gnome remove the LD_LIBRARY_PATH environment variable from my set variables? Is it because trying to do this is bad practice? UPDATE (and solution): As found by Christopher, there is a bug report about this on launchpad. LD_LIBRARY_PATH is unset after parsing of the ~/.profile file. See the bug report. Seems the only solution for now is to make a wrapper script.

• Error message when running OpenGL programs with bumblebee

  - by user170860

  X Error of failed request: BadDrawable (invalid Pixmap or Window parameter) Major opcode of failed request: 152 (DRI2) Minor opcode of failed request: 8 (DRI2SwapBuffers ) Resource id in failed request: 0x4200005 Serial number of failed request: 2166 Current serial number in output stream: 2167 primus: warning: timeout waiting for display worker Segmentation fault (core dumped) I don't get this on all OGL programs, but only particularly GPU intense ones. Also, I only get this using primusrun. optirun gives the same error no matter what I run: [VGL] NOTICE: Pixel format of 2D X server does not match pixel format of [VGL] Pbuffer. Disabling PBO readback. I don't know what either of these mean. Neither of them stop the programs from running, but I'd like to fix the problem if there is one. Also, I prefer to use primusrun because it is faster and it does a better job with vertical sync, however, it only supports OGL 4.2. This isn't a big issue because the programs I write are forward compatible, but it still seems odd to me. So basically I'd just like it if someone could explain to me what is happening and if there is something I can do about it. Thanks.

• Packages are not available under 13.04?

  - by Sven

  I have a small problem with installing packages under Ubuntu 13.04. Yesterday I wanted to install "pdfshuffler" (https://apps.ubuntu.com/cat/applications/raring/pdfshuffler/). If I go to the Ubuntu Software Center and look for "pdfshuffler" there is one item in the list (the package I want to install). When I click once on this item, the install button does not appear. If I then on furter information a error message appears telling me that there is no package called pdfshuffler in my package sources. I tried to install other packages like Eclipse or Supertux but nothing works. Why can't Ubuntu find these packages? Best regards, Sven...

• how do I go about removing all the language packs I don't need

  - by knotech

  I just noticed that in /usr/share/help I have the ubuntu help files in 70 different languages. I only speak 2, and I only really compute in one. I also noticed that it is full of broken symbolic links to /usr/share/help-langpack. I want just want to get rid of all the languages I don't need. How can I do this without getting all rm -r happy? I'm preferably looking for a way to do this without installing any new packages, as my main goal is to get rid of excess stuff on my machine. I'd like to find a way to do this preferably with dpkg, or apt.

• 12.04 LTS boot hangs at "SP5100 TCO timer: mmio address 0xfec000f0 already in use", didn't yesterday

  - by DarkIron112

  Dual-booting Windows 7 and Ubuntu 12.04 LTS. I went to reboot from Win to Ubu, and found a few interesting things. My POST screen is covered in blocks of epileptic colors until I hit GRUB, which continues when I try to boot into Ubuntu. These color blocks don't appear when I use my on-board VGA, so I'll just attribute to that. Grub dimensions are swapped (card vs onboard, probably), but, when interfacing with onboard VGA, the Grub Timeout Counter works and when using my card, it does not (see "[!!!]" below for more information) Booting into Ubuntu directly causes the error: SP5100 TCO timer: mmio address 0xfec000f0 already in use Booting into recovery mode, meanwhile, and then "resuming normal boot" gets me to the desktop without native 1440x900 resolution and graphic drivers can't tell the monitor it's looking at (I assume this is because it's not a full graphic boot, and as it says, some drivers won't run?) [!!!] When I reboot after going into recovery mode, the countdown timer works ONCE, puts me back into default ubuntu boot, and then does not work again until after another recovery-mode boot. Windows 7 can boot perfectly with no issues whatsoever from epilepsy color blocks or driver detection. This makes me wonder /why/ the POST screen can't handle my video card anymore. Amidst all the diagnostics, I opened my case and re-seated the videocard securely, ensuring it wasn't a loose connection-- But this did nothing to help me. Hardware I am running an NVidia GeForce GTX 8800 video card in a PCI slot. I have 4.8GiB memory, an AMD Athlon II Quad-core 640 Processor, on an MSI K9N6GM Series Mobo. Onboard video is an NVidia GeForce MCP61(V/S/P) card. Note: I did not have any of these problems yesterday, and I have been using Ubuntu intensively for a week, though it's been working flawlessly for months. I've recently been using it to mod my Android phone, perhaps I messed something up in the file system?

• Where do I add boot parameters to use ks.cfg

  - by user10822

  Hi, I created a kickstart file ks.cfg and then I have put that in the bootable disk*(Ubuntu 10.04)* and then added the following line to the isolinux.cfg linux ks=ks.cfg and have not removed any other lines from the isoconfig.cfg file and then while installing the installation is not automated, again it is asking for language and all. If i removed include menu.cfg or any other line from isolinux.cfg i am getting a boot error. What should i do now to automate the installation.Where should i add the boot parameters so that installation will start from the ks.cfg . Thanks and Regards Ravi Kumar

• C code - ls system command not showing bash colors

  - by m0atz

  I've just been fooling around with some code in C, an example of a really basic program is as follows which just, obviously, lists the directories using the ls system command. #include <stdio.h> int main (void) { system("ls -l -d */"); printf("I've just listed the directories :-)\n"); return 0; } This runs fine, but it shows the ls output in monochrome, whereas Bash would output the list using colors for the directories (or files if I included files). How can I make my C code use the bash colors? Thanks

• Uploading or attaching files that located on a shared drive doesn't work?

  - by Alex

  I have this odd, quite minor, but annoying issue that I am quite perplexed about. Whenever I try to upload a file via my browser(let's say attach a file to an email in GMail), I click 'Browse' button and it opens standard file selection dialog, that doesn't show network drives. Further more if I try to drag a file from a network drive into GMail, it doesn't work either, it just doesn't let me do that. This issue has been around for quite sometime now, and I am just curious if this is something on my side or if it's a bug or a misconfiguration of some sort. FWIW, I am currently running 10.10, network drive is a samba share on NAS. This happens in FF and Chrome and this is only happens with Samba mounts. As a matter of fact, NFS volumes that are located on the same network operate perfectly fine.

• How to retrieve old facebook/XMPP messages as well as new with kopete?

  - by searchfgold6789

  I have been considering using Kopete to use Facebook chat instead of logging on to Facebook with a web browser. That way, I can integrate messages with my KDE desktop better. The problem is, when I open Kopete, I am unable to see messages that I recieved in Facebook while Kopete was not opened. I can only see messages that I sent or received when Kopete was open. The same thing happens in Outlook.com (which is a website that connects to Facebook), Pidgin software, and other instant messaging tools. So my question is, how can I receive these messages with a desktop chat application in KDE, such as Kopete? Facebook has made their API publicly available to developers, and KDE has its own Facebook integration plugin. So it would seem achievable.

• System boots in console + login loop

  - by Imagicien

  I messed up my system while trying to fix permission problems for setting up a LAMP local server. I tried this solution: How to avoid using sudo when working in /var/www? without success. Then I saw this solution: Permissions issue: how can Apache access files in my Home directory? I understood that I had to change the permissions of my root directory (among others), so I executed: sudo chmod 710 / I also changed the user group on / to www-data. I also did these operations on /home. I'm pretty sure one of those commands broke something, because it's the last commands I executed, and after that, my system showed strange/broken behavior: Firefox stopped showing pages Some icons got replaced by an red X icon (meaning "Icon not found" I guess) Applications refused to launch (no reaction) After rebooting: I got a strange graphical message talking about not being able to mount something, asking me if I wanted to wait, and talking about /tmp (I forgot the message since I was in shock) My system now boots in console, and when I login, it flashes unsignificant stuff* before re-asking me to login. My important data is on Ubuntu One. I'd prefer not having to reinstall from scratch. Is there a way to regain access to my system? Thanks a lot for your help. *Looks like a terminal header with the name of the OS and other info. Doesn't seem important.

• My computer will no longer suspend or shut off when I close the lid

  - by dave

  This is somewhat annoying. I have an old laptop and the screen on it is shot, so now I have an old monitor hooked up and it works fine. Before the upgrade I had it set so that when i closed the lid on the laptop everything would shutdown or suspend, when I lift the lid, everything would come back. Now, however, when i close the lid nothing happens, when i open the lid the screen flashes black and comes back. I have it set so that it should suspend when i close the lid. It's confusing...

• BCM 4306 not recognized after upgrade on a Dell Latitude D600

  This is extremely frustrating to me. I had the wireless card working before I upgraded to 11.10.

  - by fioan89

  I've just installed Ubuntu 13.10. I have a Radeon HD 4570 card and I want to use the hardware acceleration capabilities that were introduced with linux 3.10 in the mesa 9.2 So my question is: since I have a linux 3.11 and mesa 9.2, do I really need to compile the mesa library with --enable-vdpau option enabled? I have installed the libvdpau from the repository but no acceleration. Should I compile and then install the latest mesa(I don't want to mess my newly installed Ubuntu 3.10)? Thanks!

• Applications Menu disappeared

  - by Sophie Sperner

  I'm using Ubuntu 12.04, classic desktop without effects. Once the indicator-applet-complete (right part of the top panel) had been disappeared. I found how to fix it: Alt-Win-RightMouseClick on the panel, then "Add to the Panel", where choose "Indicator Applet Complete" to add. Now, the left part of the top panel (Applications Menu) has been disappeared! If I do Alt-Win-RightMouseClick on the panel, I can add only individual Menu sections like Internet, Office, Settings etc. But how to get back the full Menu as it ought to be?

There are already 4 partitions on my hard drive ( one windows 7 , one system tools ( windows 7), one for ubuntu and one for common media storage(ntfs)). Therefore Gparted didn't allow me to create any further partition for swap volume.All it said to create an extended partition, but i do not know to do this. I want to create a swap volume out of common media storage. How can i accomplish this? And I'm completely new at Ubuntu , so can you suggest some good getting started tutorial for it?

• Can I define keyboard shortcuts using the Super key?

  - by Rasmus

  In 10.04, I had a lot of keyboard shortcuts defined using Super/Mod4 and one single other key, Super+O ran Opera Super+W opened Nautilus pointing to my Work folder, etc. In 11.04, these do not seem to work -- only Super+R works to run the terminal, and Super+Shift+W successfully runs Nautilus. Is there some way I can get these to function again? Adding them in Keyboard Shortcuts does not work, and neither does adding commands in CompizConfig Settings Manager.
