• Bluetooth refuses to connect since update to Ubuntu Gnome 13.10

  - by Niklas Berg

  I can no longer connect to my bluetooth speakers since since upgrading to Ubuntu Gnome 13.10 and then Gnome shell to 3.10, which never were a problem with Ubuntu Gnome 13.04. My bluetooth-dongle seems to working fine and I can even detect and add the speakers (Creative D100) but when I try to slide the button from off to on in the bluetooth settings it just slides back to off. The "bluetooth-B" in the upper right corner is also gone. I actually managed to connect after I added "Enable=Socket" under "[general]" /etc/bluetooth/audio.conf and the indicator on the speakers confirms the connection, but I cannot find the speakers in the audio settings even then. I've tried to solve this for several days, reading tons of other possibly related questions here on ask ubuntu and elsewhere but am unable to find a solution. Any ideas?

• xkb for simple remap

  - by Den Rimus

  I've faced some issues after remapping keyboard with xmodmap: settings get reset randomly after 2-20 minutes after applying. Googled it but no help: something resets them, but all mentions apply to xfce, while I'm under usual 14.04 Ubuntu with unity. I saw phrases like 'use xkb, forget xmodmap', but still have no idea how to do that. It's either classified or very complicated, because amount of info on that is significantly smaller than for xmodmap way. Here's my list of customisations: xmodmap -e "keycode 84 = Down" xmodmap -e "keycode 79 = Home" xmodmap -e "keycode 80 = Up" xmodmap -e "keycode 83 = Left" xmodmap -e "keycode 85 = Right" xmodmap -e "keycode 87 = End" xmodmap -e "keycode 90 = Insert" xmodmap -e "keycode 91 = Delete" xmodmap -e "keycode 89 = Next" xmodmap -e "keycode 81 = Prior" where keycodes are corresponding keys on numpad, with numlock = off (basically, I'm replacing KP_Del with Delete, KP_Home with Home etc - don't ask why)) Can someone help to find a way to do that using xkb - at least one of the lines? And where to find the "names" of keys for other so I could do the rest by example?

• Can't add more than eight keyboard layouts

  - by Woofi Alakhi

  I read this article where is a workaround to add maximum eight keyboard layouts. But my questions are: I would like to try this, but I see they've written there something with "gnome" in the script. In my Ubuntu, 13.04, I have Unity. What do I do? I would have to do this for four x four keyboard layouts (to have 13 keyboard layouts). This script, however, is designed for two x four keyboard layouts. How do I get the four x four? I would really appreciate your tips and hints on this. And I would kindly ask you to keep it simple, if possible, because I'm really no expert in both Ubuntu and computers in general.

• How to zoom in&zoom out

  - by stanimir

  While using 10.04 and the previous versions I used to put ctrl+F6 to zoom in and subsequently ctrl+F7 to zoom out. Now I can't even find the options to zoom in and zoom out in the "keyboard shortcuts". I tried "the Magnifier" in the Compiz but really can't understand what is going on right there. There is simple question I would like to ask: What to do so as to be able to zoom in with ctrl+F6 and zoom out with ctrl+F7? Thanks a lot.

• How to mount an ISO (or NRG) image and rip it as if it were a physical CD?

  - by Michael Robinson

  I have an ISO (created from an NRG with nrg2iso) backup of a beloved game from my youth: Dark Reign: Rise of the Shadowhand (1998). I with to relive those better times by listening to game's soundtrack. Is there a way for me to mount said ISO in such a way that I can rip the audio tracks into mp3 files? I ask because although I can successfully mount the ISO, ripit / abcde report no cd inserted. How I mounted the ISO: sudo mount -t iso9660 -o loop iso.iso /media/ISO Alternatively is there another way to recover audio from ISO / NRG images? Update: I was able to mount the NRG version of my backup in a way that ripit recognized using gCDEmu. ripit failed to rip, however, barfing on the first track - which is most definitely a data track. Is there a way to make ripit ignore the first track?

  - by Kaushal Singh

  I am stuck with a very annoying problem which does not allow me to even install Ubuntu on my laptop (Dell Vostro 1510). In a simple walk through of the problematic scenario...

Then the option come where a.) try from the live cd b.) install ubuntu c.) etc etc Is needed to be selected. For which I press enter. Once I press enter... In any of the next steps of installing Ubuntu, my keypad and touch pad does not work. P.S.: My Batteries are completely dried Up... Can't use batteries. Does this problem has anything to do with batteries?

• Unable to get screen signal after purge FGLRX

  - by Boris

  I thought that my ATI driver was not running well so I wanted to re-instal it completely. I did: sudo apt-get remove --purge fglrx* sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon and after a boot I wanted to intal the ATI driver BUT at the boot no more signal to my screen. Since, every time I turn on my PC it gets to purple screen and then screen shuts down ! Note that: Even if the screen is off, PC seems to be running almost well: I m still able to use my network to access data shared with NFS. Using live USB I have no screen problem. I tried to plug my screen on an alternative output but it did not work. I tried CTRL+ALT+F1 while being on purple screen but it does not do anything, screen shut down anyway. I m going to try the SHIFT thing and learn from blackscreen wiki...

• Permission denied after creating home partition

  - by Magnus

  I have recently created a separate home partition following this tutorial https://help.ubuntu.com/community/Partitioning/Home/Moving. Since I’m still a newbie in the Linux (struggling to learn) I felt happy when every thing seemed to work smooth. How ever, I realised after a while that I had lost all permission to my subfolders in the my home folder. I still can read/write the files placed directly in /home/magnus but I'm denied access to any of the subfolders. I just realised one more disturbing thing, probably related to home-partition story above: When I try cd ~/Music/ I get the message bash: cd: /home/magnus/Music/: Permission denied When I try: sudo cd ~/Music/ I get the result sudo: cd: command not found Seems strange that the cd command have been lost? What have I done wrong and is there a way to fix this? btw: I use Ubuntu 12.04 LTS Thanks for all the help! Magnus

• Unable to install any packages due to unrecoverable fatal error /var/lib/dpkg/diversions

  - by gforces

  I am currently unable to install any packages. I receive the following error: dpkg: unrecoverable fatal error, aborting: too-long line or missing newline in `/var/lib/dpkg/diversions I have tried various approaches: sudo dpkg --configure -a sudo apt-get clean sudo dpkg-divert --list sudo apt-get check sudo apt-get install -f etc. but all to no avail. Either the output was apparently normal or the error above was thrown. I'm stumped as to how to proceed and would appreciate any assistance. If any further info is required just ask. Thanks for the reply. I followed the suggestions and am now getting a different error: (Reading database ... 50%dpkg: unrecoverable fatal error, aborting: files list file for package 'libksane0' is missing final newline E: Sub-process /usr/bin/dpkg returned an error code (2) Here is the link for the current diversions: http://paste.ubuntu.com/823500/ and the old broken one: http://paste.ubuntu.com/823502/ I tried to reinstall libksane0 but the same error occurred.

Wouldn't ask if I knew! :) I'll be glad to post more info if someone needs it!

• Can Ubuntu launcher damage my LCD screen pixels?

  - by DUKE

  There appears something like a scar (damaged or dead pixels) on my LCD screen, where Ubuntu launcher positions. The scar exactly fitting Ubuntu launcher edges and icons.

• Adobe flash plug-in crashed/needs permission in Chromium

  - by sally

  A couple of days ago I started to get these messages when trying to watch videos on Youtube and a couple of other sites. (Using Chromium browser) Normally starts by just seeing a black screen with Missing Plug-in faintly visible, but will also ask me to give permission to run both at top (yellow bar), and if I tell it to 'allow' it follows up with the white puzzle piece on black background requesting permission. Occasionally I have seen the message telling me the flash-player has crashed, too. Giving permission does not fix the problem. Have also navigated to 'about:plugins' and checked that Adobe flash is enabled and permitted. I have just done a fresh installation of Lubuntu 11.10 as a last resort but problem still not fixed.

• How do the environments of a standard Terminal command-line and a bash script differ?

  - by fred.bear

  I know there is something different about the environment of the Terminal command-line and the environment in a bash script, but I don't know what that difference is... Here is the example which finally led me to ask this quesiton; it may flush out some of the differences. I am trying to strip leading '0's from a number, with this command. var="000123"; var="${var##+(0)}" ; echo $var When I run this command from the Terminal's command-line, I get: 123 However, when I run it from within a script, it doesn't work; I get: 000123 I'm using Ubuntu 10.04, and tried all the following with the sam results: GNOME Terminal 2.30.2 Konsole 2.4.5 #!/bin/bash #!/bin/sh What is causing this difference? Even if some upgrade will make it work in scripts... I am trying to find out the what and why, so in future, I'll know what to look out for .

• Use a proxy which connects to the school proxy

  - by denNorske

  How to get my computer use a proxy ON my computer, which connects to the school proxy ? The reason I ask this, is because I need all programs on my computer, absolutely the whole system to go through the network, without having to use proxy authentication? Then I was thinking of a possibility to use a local proxy without authentication, to connect to the school proxy (with all authentication details), and then be able to make the system go through it? Is that possible? I've heard some stories about using IP-tables to make a transparent proxy, but I have no idea how to do that, as i am pretty new at all this. So, details, explanations and suggestions about this are very welcome! If you need more details, I'll provide them!

• Video Training Courses for Linux/Ubuntu?

  - by Anil

  I'm a software developer with more than 15 years of experience on Windows platform, focused on C#/.NET/SQL Server stack. Recently I decided to explore Linux and learn a new development technology stack which is completely unrelated to Microsoft. After a bit of (re)search/reading I picked Ubuntu as my starting point. As I'm really a Pluralsight addict, preferring video courses as a starting point for learning new stuff, I wanted to ask if there are any decent video courses for Linux generally or Ubuntu focused ones? Basically I'm searching for general explanation of OS structure, a bit of system administration, and maybe some considerations for development on Linux system.

• Building small Ubuntu server - What hardware is recommended?

  - by 10robinho

  There are many of us who need to build small Ubuntu server. Problem is that in some countries it is hard to find and quite expensive to buy server motherboards and processors. And when one is building small server with limited budget, buying some Xenons is not really an option. So, are there any general recommendations for hardware (I think that motherboards are the main issue) that is stable and fast under Linux? I read that Intel should be the best choice for cpu + mbo combo. So, I was looking around for some Intel motherboards + i7 Ivy Bridge (like Intel DZ77BH-55K with Z77 chipset and Intel i7 3770K) but I've read that they have some issues with kernel, booting and USB ports. That is why I ask community if you have any experience with this. Maybe Intel is not the best choice here? Maybe ASUS or Gigabyte or _other company_ are more stable with Linux? I hope that this Q&As can help people in building stable Ubuntu server.

• Do I need an Ubuntu certification to teach Ubuntu

  - by Luis Alvarado

  I have several students that want a course of Ubuntu. I would like to know the following very important points: Do I need an Ubuntu certification to certified my students afterwards that they know Ubuntu. Can I use the Ubuntu logo, an Ubuntu symbol for the certificate that I would give out? Do I need permissions? Where should I ask for permission? Is this possible? Is there an Ubuntu certificate format available that I could use? Is there a site where I could sign to teach and promote Ubuntu to new users (Become an Ubuntu teacher)? What information and permissions might I need from Ubuntu or Canonical if I wanted to give courses about Ubuntu?

• How to revoke gnupg public key without private key?

  - by danijelc

  Long story short I have an key generated with seahorse and mistakenly deleted it from my system. I do remember passphrase but I don't have this key anywhere on my system. Scanned trough Ask Ubuntu but couldn't find any aplicabile solution on similar issue. However public key is still updated on keyring servers and I would like to revoke it. Since I have no revocation certificate and I can't get hold of private key (only public key is available from keyservers which I imported to seahorse) I have no idea how to accomplish it. Spent some time searching for solution acros net, various manuals and so on, but so far no luck. gpg --list-secret-keys - returns no output at all. gpg --list-keys - returns public key info gpg --gen-revoke *user-id* - returns - gpg: secret key *user-id* not found: eof gpg (GnuPG) version 1.4.11. Anyone able to suggest a solution?

• How can I open an .xps file in Evince?

  - by Jakob

  On projects.gnome.org I read that evince/Document Viewer supports xps-files. But when I try to open an xps-file I get the error message Unable to open documentFile type Zip archive (application/zip) is not supported Reading "the full list of supported document formats" on live.gnome.org I can't find xps there. Now I ask myself (and you): Isn't Document Viewer able to open xps-files, or is there something wrong with that xps-file I try to open? I specifically want to do this with Ubuntu 11.10 Oneiric. The PPA ppa:medigeek/evince-xps has no solution for 11.10, and the xpstopdf utility mixes up the letters from my xps file totally - the new pdf then isn't usable. I want to see a solution for Evince or Gnome in general, not get a recommendation for a KDE application like here.
