  - by deepak365

  Issue: After installing cinnamon 1.6 the unity desktop environment having some cinnamon settings. Yesterday I installed cinnamon 1.6. It causes some changes in my unity desktop environment. After login in Unity: I am getting a "Open in a terminal" option while right-clicking on a desktop. While I am trying to open "Change Background Option " after right-clicking on desktop, cinnamon setting is opened instead of Ubuntu default setting. Please help me to getting back default options in unity desktop. (I don't want to remove cinnamon). I am using Ubuntu 12.10

• How do I execute a file from a FAT USB drive?

  - by Derek Redfern

  I'm trying to install a portable app onto my USB drive such that it is compatible with both Ubuntu and Windows (specifically, a program called eToys). Support is already built into the app for both operating systems - there's etoys.sh for Ubuntu and etoys.exe for Windows. I decided to install onto a FAT drive since that can be read from both systems. This works fine for Windows, but for some reason I cannot execute etoys.sh on Ubuntu. The problem is not with the file - when the whole folder is copied to the local hard drive, the app works great in Ubuntu. But when I try to execute it from the USB, it opens the file in a text editor. I then tried running it from a terminal, but I got the message "Permission denied." I've had the same problem with other executables as well. Is there an easy way to execute things from a USB stick? Thanks! -- Derek

• I cannot search/find any applications in the Dash on 12.04

  - by Russell

  Its been a while since I booted my Ubuntu (12.04), but when i did I had several updates (over 100) and I installed them along with rebooting. These updates seemed to mess with my video driver but I seemed to have fixed this. My problem is that my applications do not show anywhere. I can open them via terminal or if there are shortcuts (such as on the toolbar) but if I hit Super and go to Apps, there is nothing. This is true if I hit Super and search any app name nothing will come back (except for files). I need help to understand what happened! Also for some reason I can't upgrade to 12.10 (I assume because I have 12.04 and not 12.04.1, which I don't understand how to get).

• Missed environment variables in Eclipse Juno

  - by hara

  I recently moved from Eclipse Indigo to Juno. I installed the IDE in my Ubuntu 12.04 by downloading the archive from here. Then I created an entry in the unity launcher for Juno as I done before for Indigo. Here is what I wrote in ~/.local/share/applications/eclipse-juno.desktop: [Desktop Entry] Type=Application Name=Eclipse Juno Comment=Eclipse Integrated Developmentm Environment Icon=~/.eclipse-juno/icon.xpm Exec=~/.eclipse-juno/eclipse -vmargs -Duser.name="my name" Terminal=false Categories=Development;IDE;Java; When I run eclipse from the unity launcher, eclipse does not see environment variables that I set in ~/.bascrc. Instead, if I run eclipse from shell, it can see all the env variables. How can I fix the problem? Thanks a lot.

• install Cirrus Logic cs46xx (audio card) drivers

  - by Aikanáro

  I have two sounds cards, one is the on-board (it's VIA) the other is Cirrus Logic cs46xx. This is what lspci shows me: 04:04.0 Multimedia audio controller: Cirrus Logic CS 4614/22/24/30 [CrystalClear SoundFusion Audio Accelerator] (rev 01) It only show the cirrus logic, cause I disable the VIA card through BIOS. This page: http://es.driverscollection.com/?file_id=13152 gives me instructions to install it, but I can follow them because the folders indicates in the page do not matches with the ones that I see in my system. The alsa page: http://alsa-project.org/main/index.php/Matrix:Module-cs46xx, also give me instructions, but I don't understand it. For example, they say: type in a terminal: ./configure but don't say in what directory. I think that isn't instructions for begginers... Right now I can't heard anything. I decide to disable the VIA audio card, cause I've read they don't get along with linux, although i use the integrate VIA video card. I have ubuntu 11.10

• RAM Cache always full

  - by Tobias

  I have 6GB RAM, i5 2.4GHZ Processor running Ubuntu 11.10. When streaming online or opening several tabs in Chromium I soon have 4GB Memory in the cache. And this makes my Notebook slow. When streaming a video, after a few minutes it really slows down and stumbles/jerks. I partitioned my HD so that I have 8GB swap. What could the problem be? How can I solve this? P.s: initially I had 4gb and recently upgraded to 6GB, but I did not experience a significant change. P.P.S: if I enter "free -g" in the terminal this is the result: total used free shared buffers cached Mem: 5 2 3 0 0 0 -/+ buffers/cache: 1 4 Swap: 8 0 8

• How do I mount this HDD?

  - by Casval Deikun

  I have a Windows HDD attached to an external docking bay on my Ubuntu System, but the HDD brings up an error message: Mounting exited with exit code 14:windows is hibernated, refused to mount. Failed to mount '/dev/sde2':Operation not permitted. The NTFS partition is hibernated. Please resume and shutdown windows properly or mount the volume read-only with the 'ro' mount option, or mount the volume read-write with the 'remove_hiberfile' mount option. For example type in command line: mount -t ntfs-3g-o remove_hiberfile/dev/sde2/media/FE46D60C46D5C615 I am at a loss for exactly how to remove the hiberfile, or even mount it as read-only or read-write. I tried directly copy and pasting that exact command into my terminal, but it said: mount:only root can do that I do not know what to do at this point. I do need to get the information off of this drive, but I do not have a computer to put it in. Does anyone know what I should do from here?

• Gnome Mplayer failed to open VDPAU backend libvdpau_nvidia.so

  - by Tim

  When I open an avi file under Gnome Mplayer, there is an error report: Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory I then followed this blog to solve this problem, which suggests two ways. The first way is to call mplayer in terminal: mplayer -vo xv video.wmv This works for me. But I would like to try the second way, which is to write options in one of the configure files of Gnome Mplayer. I choose to write into ~/.mplayer/config, where I wrote: -vo xv But it does not work. So I was wondering if I make any mistake? What to write into the configure file? Thanks and regards!

• Should security updates 'always' be installed?

  - by kmansoor

  We are a small shop, no real sysadmin. So developers (Java EE) also try to maintain Ubuntu server 12.0.4. When I login a terminal and I see messages like: 6 packages can be updated. 6 updates are security updates. Should all security updates always be installed? can some be ignored? Should these be acted upon immediately? Or one could wait for 2:00 AM coming Sunday? Is there a way to know a 'critical' update? Is there a good sysadmin for dummies resource I should be reading?

• How can I break out of ssh when it locks?

  - by Wayne Werner

  Hi, I frequently ssh into my box at home from school, but usually when I change classes and my computer suspends, the pipe will be broken. However, ssh simply locks up - ^c, ^z and ^d have no effect. It's annoying to have to restart my terminal, and even more annoying to have to close and re-create a new screen window. So my question, is there an easy way to make ssh die properly (i.e. when the pipe fails "normally" it will exit with a message about a broken pipe)? Or do I have to figure out what the PID is and manually kill it? Thanks!

• Low graphics mode on Ubuntu 12.04 with Intel Graphics

  - by NightShadeQueen

  When I boot, my computer just tells me it can't detect graphic card (or something else) settings and it has to use the low graphics mode. Then it gives me four choices, but doesn't let me choose any of them. I can get my computer to boot by going to some sort of terminal mode and then typing sudo gdm. The other graphics manager I have is lightdm. I originally had the nVidia propriety driver, and I've tried bumblebee. Mobile Intel Graphics Media Accelerator 4500M is my graphics card. Is there any way to fix this so I can use lightdm again?

• Ubuntu 12.04 GTK Problem

  - by Dana Holt

  I am running Ubuntu 12.04 and compiled and installed GTK 3.4 to go through some GTK developer tutorials. Installing this version of GTK has caused problems with Unity. All system dialogs and top bar now have a different (older) look, and when I try to launch Nautilus I get the following message: Gtk-Message: Failed to load module "canberra-gtk-module" Initializing nautilus-open-terminal extension Initializing nautilus-dropbox 1.4.0 Initializing nautilus-gdu extension nautilus: symbol lookup error: nautilus: undefined symbol: ubuntu_menu_proxy_get I have run make uninstall on the newer version of GTK and reinstalled just about every package I can think of, but I am still having the same problem. How can I repair the default Ubuntu GTK libraries? EDIT Also, I noticed that my desktop icons are gone (launcher works), and I can't interact with the desktop. I can't drag any shortcuts to it, etc.

  - by LittleBobbyTables

  I'm desperately trying to install ubuntu 12.10 64bit on my new Ultrabook. Its a Sony T13 with 8gb ram, 256gb ssd, i7, windows 8. I have an extra partition, D: "UBUNTU" already created with about 30gb space using FAT32. Ubuntu is MD5 checked, on a previously working USB stick using UNetBootin. Grub loads fine When I ask to test out Ubuntu ("Try ubuntu without installing") it shows the purple loading screen for a bit then brings up this error in a busybox terminal: initramfs - Unable to find a medium containing a live file system Things I've tried that don't work: Different versions of Linux (Fedora, Arch, SL, even gParted) Using USB2/3 - No difference Legacy or UEFI - different interface, but same error BIOS has no option for anything "ACHI" related I have read through tons of other people having this problem and diligently tried all the above solutions, with no luck.

• Prevent nautilus showing partition mounted in bash script

  - by bcbc

  In my bash script I mount partitions, check them, copy files to them, and unmount. When the script mounts the partition, Nautilus pops up with a Window showing the partition and stealing focus. This is something I want to avoid. Note: I know I can change the behaviour of this in System settings, Details, Removable media, Never prompt or start programs on media insertion, but I don't want to change the behaviour e.g. if a USB stick is plugged in, I just want to prevent it in my bash script. Actually this auto display doesn't seem consistent. If I do the exact same command from the terminal, Nautilus doesn't show, and I know there are other mounts in my script that don't show. So what could be causing this? Here's an example of the code: mkdir -p $target/home mount $target/home $homedev Thanks in advance

• How do I install Sublime Text 2?

  - by Michael Gruber

  I installed Sublime Text 2 on 12.04 as per this tutorial. However I don't have adequate permissions when launching the program from the Unity launcher. For example I cannot install packages, or if I add a folder to the sidebar when I close Sublime and reopen, the folder is no longer listed. If I run sudo sublime in the terminal all changes remain after closing. I've tried chown-ing the Sublime Text 2 folder in usr/lib sudo chown -R mylogin:mylogin /usr/lib/"Sublime Text 2" but this seemed to have no effect.

  I followed the steps of this guide and it doesn't work. I've entered the following command and I had an output with dependencies error. sudo dpkg -i fglrx*.deb So I tried with gdebi instead, and it works. Now fglrx & fglrx-amdcccle & fglrx-dev are installed. The next step is Generate a new /etc/X11/xorg.conf file, but I can't do this due to the following reason: When I enter sudo aticonfig --initial -f the terminal show me this output: sudo: aticonfig: command not found I've installed the packages correctly or not? What I have to do to fix the problem? NOTE: I've not uninstalled nothing (drivers, config., etc.) before beginning the installation.
