  • No programs or applications show up in dash

    - by sky
    There are no programs on the dash list (seacher on appmenu). Yesterday I logged into my account and I tried to find a particular program, but there weren't any! Additionally, I tried to view installed programs and manually find programs, but nothing was displayed. And today, when I wanted to turn on Ubuntu Software Center, it just don't turn on. I'm using Ubuntu 11.10 (64bit). I installed this as a "fresh" OS a few days ago. Ubuntu is updated and has many Gigabytes of disk memory available.

  • Unable to mount NTFS Partition after resizing

    - by sam
    I was having only 15 GB space allocated to LINUX. I wanted to have more space available to linux. So I just re sized one of my ntfs partition using GParted. But after resizing I am not able to open the partition neither in Ubuntu nor in windows. OS: Dual Boot Win7/Ubuntu 10.10 The error message i get is the following: Error mounting: mount exited with exit code 12: Failed to read last sector (395458824): Invalid argument HINTS: Either the volume is a RAID/LDM but it wasn't setup yet, or it was not setup correctly (e.g. by not using mdadm --build ...), or a wrong device is tried to be mounted, or the partition table is corrupt (partition is smaller than NTFS), or the NTFS boot sector is corrupt (NTFS size is not valid). Failed to mount '/dev/sda5': Invalid argument The device '/dev/sda5' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

  • Hide debug information when running apps from the command line

    - by tutuca
    Most of the time running a gtk application from the command line it starts dumping debug information to the stdio even though I put them in background. Example: ~$ gedit test.html # and ctrl+z to suspend zsh: suspended gedit .zshrc ~$ bg [1] + continued gedit .zshrc ~$ # do some editing (gedit:6208): GtkSourceView-WARNING **: Could not find word to remove in buffer (whoosh), this should not happen! (gedit:6208): GtkSourceView-WARNING **: Could not find word to remove in buffer (haystack), this should not happen! I want to note that the error, or warning, changes according to what I'm doing at the moment. The GtkSourceView-WARNING shown here is one of the cases. Anyway... Do you know if it's at all possible to avoid getting that information printed out?

    - by Sebastien Lachance
    I'm trying to set a redirection in my VirtualHost configuration for my website. So far I am able to redirect non www trafficto the www address like this : <VirtualHost: *:80> ServerAlias www.gcbeauce.com RewriteEngine on RewriteCond %{HTTP_HOST} ^guidedescommercesdebeauce\.com$ [NC] RewriteRule ^(.*)$ http://www.guidedescommercesdebeauce.com$1 [R=301,L] But what I also want is to redirect the old domain to this new one.

  • Google Desktop shortcut Ctrl + Ctrl weird behavior

    - by Leonid
    Just noticed a weird behavior of Google Desktop shortcut Ctrl + Ctrl. This shortcut is supposed to bring Google Desktop search bar to the front. If Ctrl + Ctrl is pressed the search bar appears, but once you release one of the Ctrl keys it will disappear. If you hold one Ctrl key, and press the other twice the search bar will toggle it's state. Do you have any idea how this can be fixed and what can be causing this behaviour?

  • How to associate hardware volume control to USB speakers?

    - by Wolfger
    My Xubuntu system recognizes my speakers, and I can change the mixer settings to make them the active sound device, but no matter what I do, the hardware dial will only affect the onboard sound device. generic-usb 0003:046D:0A19.0003: input,hidraw1: USB HID v1.00 Device [ Logitech Logitech Z205 ] on usb-0000:00:1d.1-1/input2 updated to reflect the fact that this was Xubuntu desktop (from Kubuntu install originally) where I had this problem. I was able to easily do this from Ubuntu Natty installation.

    - by Teddy
    I updated to Ubuntu 12.04 with Compiz..now Compiz is failing and I have no tool bars or ways of getting to applications except for firefox from a link presented from sending an error report. How am I supposed to: Fix this mess with no navigation to get to the terminal, or software center. When will this problem be fixed? When I updated the system why didn't it change me back to the crappy Unity interface (No offense). If it can't be fixed how do I get my files back?

  • GRUB- error: no such partition grub rescue and Error: No default or UI configuration directive found boot > on pendrive

    - by Ash
    I have dell inspiron, previously I installed Ubuntu 11.10 on my Windows 7 and made it dual boot. But since I want to upgrade my Ubuntu version and change the partition spacing, I deleted 11.10 partition directly and extended my hardrive space (Windows + Ubuntu) at that moment everything was fine. Then I prepared a 12.04 32bit USB and installed it . It was installed but isn't showing dual boot option like 11.10 and my machine directly boot into Windows 7. So instantly i again deleted my 12.04 partition . Now I login into Windows 7 but whenever I put USB ( with 12.04 ) to boot from it, I am facing error of "no such partition grub rescue" even though I try to put lower version(11.04) it showing another error "Error: No default or UI configuration directive found boot " I have reinstall Windows 7 and reformat all partition, still I am facing same error :(

    - by Greg Pauline
    Using firefox and chrome on an Acer Aspire 5100 with an AMD Turion 64 MK36 processor with 2GB of RAM and an ATI Radeon Xpress 110 Graphics card. I had a problem viewing Vimeo and youtube that has now been resolved with the help of this website. But now I find that trying to watch Facebook videos from family and friends is impossible due to the terrible choppy frame rate and near freezing of the browser window. Any idea what is going on and how to fix it?

  • will Unity have a keyboard shortcut for accessing the "Session Menu" that appears on the panel?

    - by Sam
    I noticed in screen shots of Unity the presence of the "Session Menu" indicator in the right corner of the top-panel. This menu drops down to offer Log Out, Hibernate, Restart, Shut Down, etc. I know the keyboard shortcuts are not complete yet. But are there plans to implement a shortcut for accessing this Session Menu (i.e., so users can log out, restart & shut down without having to use the mouse)? Further, will the shortcut allow navigation through the menu by just typing the first letter of the listed word (e.g., R for restart and S for shut down)?

    - by MetaChrome
    I would like to run ownCloud client as a different user, with something like: gksudo -u owncloud owncloud However, it is specifying: ownCloud requires a working system tray. Please install a system tray application such as trayer. If you are running xfce follow these instructions: http://docs.xfce.org/xfce/xfce4-panel/systray The question remains, how does one facilitate having the owncloud user account use the parent's system tray?

  • Bluetooth mouse contstantly failes to reconnect after sleep

    - by Peter NUnn
    It seems the bluetooth subsystem shows some bugs after the upgrade to 13.10. It was working quite happily at 13.04. The bluetooth mouse I have, simply won't connect after the computer goes into any sort of sleep and has to be re-added each and every time. Sometimes the the entire bluetooth stack has vanished alltogether. What changed with the bluetooth between these versions, that may cause this? This is a fresh install of Kubuntu I'm using (bluedevil) no an upgrade, but the same hardware as 13.04 was happy on. I have reported this as a bug https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/124698 and added the link here as requested.

  • ".ts " files not recognised

    - by Keith Gardner
    I have some .ts files (programs recorded from my Sharp TV on USB stick) that I want to store/play on my PC. However, although they are listed on the stick when its plugged in the PC nothing will recognize the files. I have tried VLC (the "slider" moves but there's no sound or video) and changed the extension to MPEG, MP2, etc. but no joy. I have tried converting the files with file converters and demuxers but none of these recognize the files. Are the files corrupted (they play on the TV) or do Sharp have a unique file structure? Any help would be greatly appreciated.

  • USB device not accepting address

    - by Mike Williamson
    I have a series of machines that I am building for work that have usb card readers. When I boot them I get a long series of messages: ... [ 2347.768419] hub 1-6:1.0: unable to enumerate USB device on port 6 [ 2347.968178] usb 1-6.6: new full-speed USB device number 10 using ehci_hcd [ 2352.552020] usb 1-6.6: device not accepting address 10, error -32 [ 2352.568421] hub 1-6:1.0: unable to enumerate USB device on port 6 [ 2352.768179] usb 1-6.6: new full-speed USB device number 12 using ehci_hcd [ 2357.352033] usb 1-6.6: device not accepting address 12, error -32 ... On some older machines this only takes a few attempts before the card reader finally accepts an address, while on newer machines it can take many minutes. Changing hardware is not an option and plugging the usb card reader into a different port is only an option for the older manchines. This was a problem under 11.04 and I am now running the 12.04 beta and its still happening. Is there something I can do in the software (a udev rule perhaps?) that would fix this? Any advice appreciated. I'm happy to provide more details if you need them.

  • How to merge two .iso images

    - by pgrytdal
    I am following this tutorial to install Android onto my computer VIA Virtual Box. My problem is, they want you to download liveandroidv0.3.iso.001 liveandroidv0.3.iso.002 then they want you to merge these two files with cat liveandroidv0.3.iso.001 liveandroidv0.3.iso.002 > liveandroidv0.3.iso in the Terminal. The problem is, when I run the command, I get the following output cat liveandroidv0.3.iso.001 liveandroidv0.3.iso.002 > liveandroidv0.3.iso cat: liveandroidv0.3.iso.001: No such file or directory cat: liveandroidv0.3.iso.002: No such file or directory So, I was wondering if there was an alternative way to merge these files? Or if you guy's could help me merge them this way? Extra info: OS: Ubuntu 12.10 I downloaded the files to my /downloads folder in my home directory.

  • Screen dims on opening certain applications on Macbook

    - by yayu
    I have ubuntu 11.10 installed on an old 2008 macbook. There is an issue of screen dimming that I didnt find anywhere else on the forums. The issue is that the screen is dimmed when I open certain applications (Firefox, Software Center) and this cannot be readjusted by the physical brightness buttons on the keyboard. I tried a bunch of things on the barely barely visible screen, and had no choice but to restart. This has happened everytime. Does anyone know how to solve this?

  • Why do I get "permission denied" errors with Python easy_install?

    - by ATMathew
    I'm an Ubuntu newbie and have been trying to install python's easy_install so that I don't have to deal with source files when install Python libraries. I"ve ran the following, and it seems to install the correct applications: sudo apt-get install python-setuptools However, when i run easy_install sqlalchemy or easy_install pysqlite3, it doesn't work. I get the following error message: install_dir /usr/local/lib/python2.6/dist-packages/ error: can't create or remove files in install directory The following error occurred while trying to add or remove files in the installation directory: [Errno 13] Permission denied: '/usr/local/lib/python2.6/dist-packages/test-easy-install-1674.pth' The installation directory you specified (via --install-dir, --prefix, or the distutils default setting) was: /usr/local/lib/python2.6/dist-packages/ Perhaps your account does not have write access to this directory? If the installation directory is a system-owned directory, you may need to sign in as the administrator or "root" account. If you do not have administrative access to this machine, you may wish to choose a different installation directory, preferably one that is listed in your PYTHONPATH environment variable. For information on other options, you may wish to consult the documentation at: http://packages.python.org/distribute/easy_install.html Please make the appropriate changes for your system and try again.

    How do I customize the Unity launcher for different workspaces for Ubuntu 12.04? I am using x86-64 bit architecture running solely Ubuntu 12.04. I have searched in the community for possible aspects of this question as per the link Different Launchers for Different Workspaces? but the links provided in this doesn't address my issue as the links are outdated and it does not exactly say how to customize the launcher.

Thanks a zillion in advance. Is there any features enabling customization of launcher in different workspaces in unity 5.4?
