  • Cairo-dock only shows one workspace after upgrade to 14.04 LTS

    - by David M. Karr
    I have a Linux desktop that I try to keep up to date, although I don't use it a lot. I had it configured with cairo-dock, showing 2x2 workspaces. It's been like this for quite a while. I recently upgraded to 14.04 LTS, and now the switcher only shows a single workspace. I read several posts that talk about similar problems, but I wasn't able to get a viable clue. What can I look at to get some clues?

  • bash-completion for xelatex

    - by andreas-h
    I'm on Ubuntu 12.04. When using bash as my shell, I can just type latex my_do <TAB> to compile a file my_document.tex, as *bash_completion* does the auto-complete. However, this auto-completion does not work for the xelatex executable. So I would like to add the same auto-complete functionality for xelatex as exists for latex. I could find that the latex auto-complete feature comes from the file /etc/bash_completion, where I could find a line complete -f -X '!*.@(?(la)tex|texi|dtx|ins|ltx)' tex latex slitex jadetex pdfjadetex pdftex pdflatex texi2dvi Now I could of course just add xelatex to that line and everything is fine. However, I'm wondering if I could instead put a file in /etc/bash_completion.d, as this would leave the system file untouched. Unfortunately, I'm at a complete loss about the syntax -- but maybe someone can help me here?

  • Emacs keybindings for texboxes in firefox?

    - by Seamus
    I'm so used to emacs that sometimes, when I'm typing something in a textbox in firefox, I sometimes try and do C-p to move up a line. It is seriously annoying to have to cancel a print dialog box every time I try and move about my text. If it's not horrendously complicated, I'd like to have keybindings that emulate emacs inside textboxes in firefox... Obviously, I wouldn't need all the keybindings, but movement, marking, killing and yanking would be useful. Is this an insane request?

  • Tool to search for packages whose installed version does not match any version from a repository?

    - by Ryan Thompson
    I just upgraded from Lucid to Maverick, and as expected, all my PPAs were disabled. I have re-enabled most of the ones that I want, but I would like to get a list of all packages that I installed from PPAs that I no longer have enabled. I feel that the best way to do this would be to search for all packages where the currently installed version of that package does not match any version from a currently-enabled repository. Is there an easy way to search for such packages. Command-line solutions welcome.

    I can't load some domain on my ubuntu 13.04: youtube.com translate.google.com drive.google.com vk.com When I ping them they are responding: PING youtube.com (217.119.79.59) 56(84) bytes of data. 64 bytes from non-registered.plix.pl (217.119.79.59): icmp_req=1 ttl=59 time=21.9 ms 64 bytes from non-registered.plix.pl (217.119.79.59): icmp_req=2 ttl=59 time=20.5 ms 64 bytes from non-registered.plix.pl (217.119.79.59): icmp_req=3 ttl=59 time=21.3 ms --- youtube.com ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2002ms rtt min/avg/max/mdev = 20.544/21.255/21.914/0.560 ms But they don't load in any browser like firefox, chrome, lynx.

  • Bluetooth is always on after waking from hibernate

    - by Ali
    I have a problem that whenever my machine, Lenovo W520, wakes from hibernate the bluetooth starts. It does not matter what the situation was before hibernate. After hibernate the bluetooth is always on. Even in bluetooth settings it says that the bluetooth is off, but I can clearly see that the bluetooth LED is on. I would like to know what the problem is. Is it a hardware problem or software? How can I fix it?

  • Can I use VirtualBox as a sandbox for 12.04?

    - by Stephen Myall
    I am quite a cautious person though not afraid to experiment. I currently have 11.10 Unity and 12.04 Beta 2 running on different partitions (no problems). I have learned here that Unity can run in VirtuaBox. When I upgrade to 12.04 LTS later this month, I am curious to understand if I could also run 12.04 in Virtual Box for experimentation and test some things before I implement them into my system? Maybe there is a better way to achieve this, without partitioning my hard drive.

  • AWN displaying window icons even when Display Launchers Only selected

    - by EmmyS
    I'm using AWN with the DockbarX applet.I have Display Launchers Only checked in the awn dock properties, but I'm still getting window icons displaying for certain apps when they're open. Any ideas? Here's a screenshot, note the Firefox icon at the top of the bar (shaded icon) which is part of the DockbarX applet,then note it displaying again at the bottom of the bar (indicating an open window.) You can see from the Launchers list in the dock properties that it isn't in fact a launcher. (The Yahoo and Gmail launchers are standalone Prism apps, they don't use the FF Prism extension. And if I mouse over the bottom FF icon, it does display the title of the open Firefox window, not anything using Prism.) Any ideas?

  • Plastic Clamshell Packaging Voted Worse Design Ever

    - by Jason Fitzpatrick
    We’ve all been there: frustrated and trying free a new purchase from it’s plastic clamshell jail. You’re not alone, the packaging design has been voted the worst in history. In a poll at Quora, users voted on the absolute worst piece of design work they’d encountered. Overwhelmingly, they voted the annoying-to-open clamshell design to the top. The author of the top comment/entry, Anita Shillhorn writes: “Design should help solve problems” — clamshells are supposed to make it harder to steal small products and easier for employees to arrange on display — but this packaging, she says, makes new ones, such as time wasted, frustration, and the little nicks and scrapes people incur as they just try to get their damn lightbulb out. This is a product designed for the manufacturers and the retailers, not the end users. There is even a Wikipedia page devoted to “wrap rage,” “the common name for heightened levels of anger and frustration resulting from the inability to open hard-to-remove packaging.” Hit up the link below for more entries in their worst-design poll. Before you go, if you’ve got a great tip for getting goods out of the plastic shell they ship in, make sure to share it in the comments. What Is The Worst Piece of Design Ever Done?

  • How to change CapsLock key to produce "a"?

    - by Pit
    While typing I often hit the CapsLock key instead of the a key. (QWERTZU keyboard) This is quite annoying because the moment I realise that I hit the wrong key, I will have to delete multiple character/lines of text an rewrite them in the right form. I am searching for a way to prevent this. I have found a possibility to disable the CapsLock key in Keyboard Layout Options. But this would in my case mean that instead of writing an a I would write nothing. Positive - I don't have to rewrite a whole line, but only one character Negative - It's not that obvious that I hit the wrong key, as a missing character is not perceivable as an upper-case line of text. I would therefore prefer a possibility to map CapsLock to a . Thus when hitting CapsLock an a character would be written. Positive - If I hit CapsLock instead of a I get the output I actually wanted to type. Negative - If I hit CapsLock in any other context I will get an a character. As I don't ever intentionally use the CapsLock key this would not really pose a problem. (I think, or does it?) My Question: So how do I change to a ? And is there any case where this could be dangerous/provoke unwanted behaviour?

  • How to get shared bashed history among different tabs

    - by Luca Cerone
    I used the answer in http://unix.stackexchange.com/a/1292/41729 to enable real-time shared history among separate bash terminals. As explained in the answer above, this is achieved by adding: # avoid duplicates.. export HISTCONTROL=ignoredups:erasedups # append history entries.. shopt -s histappend # After each command, save and reload history export PROMPT_COMMAND="history -a; history -c; history -r; $PROMPT_COMMAND" This works fine if the bash shells are separate (e.g. opening different bash terminals using CTRL+ALT+T. However it doesn't work if I use tabs (from an open terminal `CTRL+SHIFT+T) rather than new windows. Why this difference in behaviour? How can I share the bash history also among various tabs?

  • Is there a difference between "." and "source" in bash, after all?

    - by ysap
    I was looking for the difference between the "." and "source" builtin commands and a few sources (e.g., in this discussion, and the bash manpage) suggest that these are just the same. However, following a problem with environment variables, I conducted a test. I created a file testenv.sh that contains: #!/bin/bash echo $MY_VAR In the command prompt, I performed the following: > chmod +x testenv.sh > MY_VAR=12345 > ./testenv.sh > source testenv.sh 12345 > MY_VAR=12345 ./testenv.sh 12345 [note that the 1st form returned an empty string] So, this little experiment suggests that there is a difference after all, where for the "source" command, the child environment inherits all the variables from the parent one, where for the "." it does not. Am I missing something, or is this is an undocumented/deprecated feature of bash? [ GNU bash, version 4.1.5(1)-release (x86_64-pc-linux-gnu) ]

  • Change from tri-boot to dual-boot

    - by Andrew Robinson
    I have been tri-booting Windows 7, Windows 8 Release Candidate and Ubuntu 12.04 LTS for a few months now. I have decided that, since I have no touch screen, I will not purchase Win 8. I now want to get rid of the Win 8 RC, then add that partition space to my Ubuntu partition, but have no idea how to accomplish this. Do I need to uninstall Win 8 RC from within Windows first? The grub loader sends me to the Win 8 loader, where I have Win 7 as the default. Does that complicate things? Any assistance anyone can give would be greatly appreciated.

  • /boot partition is NTFS on dual-boot Win7/Ubuntu 12.04 Desktop

    - by efreem01
    I recently purchased an Acer Aspire laptop. Windows 7 Home Premium edition was installed on the main drive. I booted to the Ubuntu 12.04 Installation environment and selected the option to Install Ubuntu alonside Windows 7. I now have two data partitions roughly half the size of the HD (NTFS and EXT4) and a /boot partition that is NTFS. How can i convert the /boot partition to EXT without breaking Ubuntu and Windows 7? I would like to tri-boot it with another Environment if possible, but this is presenting a problem.

  • Has anyone got Ubuntu Touch working on Nexus 5?

    - by user1628
    I have been debating whether to get a nexus 5 phone since it came out. My only fear is that I won't like android. I love ubuntu, I know that I'd love ubuntu. So I have a few question related to Ubuntu Touch: Is it easy or possible to switch between Ubuntu Touch and Android? Would I have to keep hacking the phone? Can I dual boot them? Would I lose my data every time I switch? The nexus 5 isn't mentioned here: https://wiki.ubuntu.com/Touch/Devices Does that mean it simply won't work if I follow the porting instructions? Would I have to do a bit of hacking? Has anyone got it working? Will it eventually be supported?

  • How to get exfat working in Ubuntu 13.10?

    - by davorao
    In Ubuntu 13.04 there was an option to use the PPA by Relan in order to get ExFat functionality. Seeing that in Ubuntu 13.10 this functionality is available from the repositories without the PPA I tried this but failed to make it work. Trying the PPA in Ubuntu 13.10 does not yield results either, as it complains about missing the fuse-utils package. This package seems to have been removed (https://launchpad.net/ubuntu/saucy/amd64/fuse-utils). So my question is, did the process of using ExFat change since the jump from Ubuntu 13.04 to 13.10 and how do I enable it? Old Way sudo apt-add-repository ppa:relan/exfat sudo apt-get update sudo apt-get install exfat-fuse exfat-utils Tried now via Ubuntu Software Center sudo apt-get install exfat-utils exfat-fuse

  • How to add a "Show desktop" icon to the launcher?

    I recently upgraded from 10.04 to 12.04, and there is no show desktop in the launcher. I know I can use Ctrl+Super+D, but is there a way to get it in the launcher? Edit: I just installed the "show desktop" icon on the launcher with MyUnity (see below) and it worked fine. It did not install the icon above Dash launcher, but well below it. That bug has apparently been fixed. This is as of 2012.9.30.

  • How to Use Windows 8's Storage Spaces to Mirror & Combine Drives

    - by Chris Hoffman
    “Storage Spaces” is a new feature in Windows 8 that can combine multiple hard drives into a single virtual drive. It can mirror data across multiple drives for redundancy or combine multiple physical drives into a single pool of storage. You can even create pools of storage larger than the amount of physical storage space you have available. When the physical storage fills up, you can plug in another drive and take advantage of it with no additional configuration required. Storage Spaces is similar to RAID or LVM on Linux.

  • Ubuntu 11.10 won't boot on Dell XPS 8300

    - by Phil Gorman
    I have a brand new Dell Studio XPS 8300 desktop with 17-2600 cpu, H67 chipset, 8GB DDR3, 2 1TB HDDs in mirrored RAID, and AMD Radeon 6770. Dell doesn't support Ubuntu here in Australia so it came with Windows 7 and Windows software. Yes I had to pay for an O.S. and software I didn't want to get hardware I did want, all at a greatly inflated price. It's not all beer and skittles in the land of Oz. I changed boot priorities in the BIOS to DVD and ran Ubuntu 11.10 64bit from the ISO with NOMODESET. The installation reformatted all partitions to rid me of the dreaded Windows. All was well until until reboot. The BIOS does its thing, then its "The Black Screen of Death" with a blinking cursor; no boot screen, no Grub, no keyboard, no mouse. I've searched Dell and Ubuntu forums in vain. Can you help? I would be really grateful for any advice which can help turn my big expensive paperweight into a really useful machine. Thank you in anticipation kind people. Phil
