• Laptop not syncing with Ubuntu One

  - by Lolwhites

  I have a desktop running Maverick, and a laptop running Lucid. Both are supposed to be linked to my Ubuntu One account. The desktop syncs fine, but when I started the laptop for the first time in a couple of months, it wouldn't sync any more. The Ubuntu One Preferences window either reports "Synchronisation complete" even though no recent files have been downloaded nor have any test files created in the relevant synced folder been uploaded, or it says "Synchronisation in progress", which does not appear to be happening as it stays like this for ages and the lights on my router suggest no traffic is going through. Have repeatedly tried disconnecting and reconnecting, and removing the device from the account then reattaching it, all to no avail.

• Alt-Tab looses focus and have to hit Alt-Grave Accent to get focus

  - by John Hamill

  Alt-Tab looses focus and have to hit Alt-Grave Accent to get focus I have ubuntu 12.4 with Unity window manager. I have a gvim window and a firefox window open. I hit Alt-Tab to switch between the two. Sometimes the gvim window doesn't have focus and I have to hit Alt-GraveAccent (Alt-`) to get the gvim window to have focus (ie: have the cursor a solid white square instead of a outline of a square) I do this to move between firefox where I highlight some text and do a copy, then Alt-Tab to gvim and do a paste. Sometimes the focus isn't in gvim and the paste doesn't work. I then have to do an Alt-graveAccent to get the focus into gvim or click the gvim window. These extra steps slow my process down and it makes it difficult to get into a smooth rythum. I saw this: ALT+TAB loses focus Maybe the Alt-GraveAccent may help someone. It's a unity bug: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1035628 Your best bet is to wait until an update comes through fixing it.

• How can I allow unprivileged users to shutdown from the panel? (no sudo)

  - by potofcoffee

  I set up an old PC with Edubuntu 12.04 for my girls, with an admin account for myself and normal user accounts for both of them. Unfortunately, they are not able to shut down the computer by themselves with this configuration. Choosing shutdown from the (Unity) panel menu will log them out, but that's it. How do I give them shutdown privileges? Please note that they are 5 and 7 years old and just starting to find their way around a computer. Solutions that would require them to open a terminal and sudo whatever are not helpful -- and I don't want them to be able to sudo anything, anyway. I need the panel menu entry "Shutdown" to work for them.

• screen DPI - is there and equivalent command/action to Windows 150% Display

  - by Yekhezkel Yovel

  I have a wide screen of high resolution and I see everything small on it. So In windows I set the display to 150%, I would like to do something similar in Ubuntu. Simply changing screen resolution to lower resolution doesn't help because Ubuntu is in a virtual machine and it simply changes the VM window to the actual resolution. Is there a command or a simple hack that can do the trick? EDIT: I am running Ubuntu as a VirtualBox VM on Windows 7 host.

• How can I get a java extension in LibreOffice to use the GTK+ theme?

  - by Roland Taylor

  I'm using LibreOffice with the LanguageTool extension, and it is kinda out of place (the options dialog at least) because it uses the open solaris default theme instead of my gtk+ theme. Is there a way to get it to use my gtk theme? Screenshot: Edited my question - it's not the default theme it uses, my apologies Additional details - it appears to be a webstart application or something, but I'm not a java expert so I don't know for sure :P

• Permission denied on /dev/xvdf despite sudo?

  - by Sid

  I'm trying to get a stream off port 9999 and write to /dev/xvdf. I'm using Amazon EC2 with the Ubuntu 11.10 server image. By default I log in as 'ubuntu' which has sudo privileges. However, when I run the following netcat command, I get this error ubuntu@ip-10-252-35-122:~$ ls -al /dev/xv* brw-rw---- 1 root disk 202, 1 2011-11-30 22:22 /dev/xvda1 brw-rw---- 1 root disk 202, 80 2011-11-30 22:27 /dev/xvdf ubuntu@ip-10-252-35-122:~$ sudo netcat -p 9999 -l > /dev/xvdf bash: /dev/xvdf: Permission denied ubuntu@ip-10-252-35-122:~$ Any idea why I get the permission denied error and how I can work around it?

  AZUS Sabertooth Motherboard, Intel I5 2500 CPU, Windows 7 installed I'm trying to install linux. I first attempted to install pin guy. I burned the ISO; booted from it; got the initial menu; attempting either run the live version from DVD, or install to system; the process stops at a blank screen with the blinking cursor in left corner. So I downloaded Ubuntu and got the same results. Then tried wubi, and ended up in the same position; blinking cursor in left corner.

• Totem streams only certain video from iphone

  - by Hans Schmidt

  I recently installed a plug-in for Totem movie player. This allows the app to receive and play AirPlay-streamed video from iphone to totem player: http://www.omgubuntu.co.uk/2011/01/airplay-video-playback-comes-to-totem Actually this works fine with youtube videos. But when it comes to other apps in iPhone (such as Digital TV App) the streaming does not work. In the app I can choose Totem Player, but Totem Player itself stays empty, i.e. nothing will be streamed. As mentioned choosing Totem Player for youtube video works fine. Do you guys have any idea what makes the difference that it works only for youtube?

• chromium-browser --proxy-server debugging

  Many places online have pointed out to configure chromium proxy via command can be achieve with the following line chromium-browser --proxy-server=[username]:[password]@[host]:[port] but I got this result on every request.

• Graphic Card Installation Failure (NV 9600M GT)

  - by Georg

  I wanted to switch from 7 to Ubuntu. Now, the first thing that holds me back is the installation of the driver for my Nvidia 9600M GT. Ubuntu recommends me 4 drivers from the "Additional Driver" Section. Now, whatever driver I install, there are four things happening RANDOMLY after rebooting: The pc freezes before seeing bootup splash The pc freezes while seeing bootup splash image (ubuntu logo with the 5 dots) The pc gets into login screen and freezes instantly (Thought the unity-bar is transparent now) The pc freezes right after beeing able to login. (While this is happening the unity-bar changes from transparent to ugly-flat-style) I also tried to install the official Nvidia .run file but after exiting the X-Server, it says the driver is not compatible with the kernel and exits installation. Can somebody help me? I really wanna get rid of Windows :( But Ubuntu drives me perfectly insane. Please answer as noobish as possible. I'm an expert Windows user, but Linux is absolutely new to me. My Specs: Ubuntu 11.10 installed from USB Stick (like 100 times now :/ because I dont know how to remove the driver in recovery mode) 9600M GT 4GB Ram Intel Centrino 2 Dual Core 2.26GHz Win 7 and Ubuntu running along side. Thank you in advance, regards.

• How can I force X to start in a computer without a monitor?

  - by Javier Rivera

  I have I computer that have no monitor attached. When I boot it X fails to start because there is no monitor detected. If I boot it with a monitor attached and after X is started I remove the monitor everything works fine. Details and Background: This computer is a kind of hardware consolidation server. It's only purpose is to run two Virtual Box VM's that run Windows XP and some important but seldom used (once or twice a month) programs. For a couple of time it has been lying in a corner with an old monitor attached to it and working great. But space in the office was getting scarce and I moved the computer to the server room. There is no monitor attached to it there (no space), and sometimes the computer is rebooted. When it boots without monitor X is not started, the vms don't start and I get called to solve the problem.

• 10.10 - No wired connection (cable plugged)

  - by Roland Burda

  So, my problem is that I have a recently bought laptop (Dell Inspiron M5040) with Ubuntu 10.10 installed on it, and the wired connection isn't working. The wireless connection is ok, it works.

• How to install gluezilla-dev?

  - by Petr

  gluezilla was removed from latest Ubuntu repository for some silly reason. This library is necessary for mono web libraries to work properly (without gluezilla the web browser component doesn't work). How do I install it on Ubuntu? It has an incredible dependency tree of packages that were in older Ubuntu versions but for some reason aren't in current Ubuntu. Is there any way to install it other than downgrading to older Ubuntu?

• Confused about application submission

  - by snowflake

  I finished my app but I'm totally confused about how to submit it to launchpad and the software center. I'm also new to launchpad. 1) I created a project at launchpad and synchronized an OpenPGP key via the password tool. This was about 30 minutes ago but launchpad still shows "No OpenPGP keys registered." Is this normal? 2) What I have to do next with the PPA? 3) How do I submit my app? Do I have to adjust files with the PPA? The showdown blog shows that quickly submitubuntu is enough but here in the forum I read about quickly release or quickly share. So which one is correct? 4) Do I have to add this file to launchpad as well? 5) Do I get a confirmation that my app was correctly submitted and take part of the contest? Since I do it for first time I want to be sure that everything is ok. I'm sorry for all my questions and I know that there are many topics about it but everywhere something different is written and I'm confused how to proceed. Thanks in advance!

• Problems building application for Ubuntu App Showdown

  I have managed to submit my source application to the Ubuntu build servers, however it's not building. This is the build output: https://launchpadlibrarian.net/109592385/buildlog_ubuntu-precise-i386.liberedit_12.07.20_FAILEDTOBUILD.txt.gz I know that there is a dependency on lxml for my application but I don't know how to correct that, but I can also see that it's failing to find my own python modules. I am not sure what is going on in it's entirety here, but I would greatly appreciate getting this to build so I can submit it to the Ubuntu App Showdown. Thanks, Neil

• Ubuntu won't boot after initializing the Build Environment for Android

  - by EntryLevelDev

  My laptop worked perfectly util I initialized the build environment for Android. The GUI won't start. It looks like some kinds of graphics card problems. I tried to fix it but after trying a lot of solutions on the internet nothing worked. (I only know basic linux stuffs.) I've already reinstalled the OS. However, I still want to build the Android from source. Any idea what might cause the problem? any workaround? Here is the command that I used to initialize the build environment: $ sudo apt-get install git gnupg flex bison gperf build-essential \ zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \ libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \ libgl1-mesa-dev g++-multilib mingw32 tofrodos \ python-markdown libxml2-utils xsltproc zlib1g-dev:i386 $ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so My laptop model is asus u36sd.

• Volume range is narrow in 12.04

  - by Alejandro

  I have upgraded to Ubuntu 12.04 and I have a problem with the volume. The problem is that the volume is 0 when the volume bar is between 0% and 66% more or less, so the actual volume range is only between 66% and 100%. If I open the sound configuration menu, the position in the volume bar that makes the sound begin sounding (66% more or less) is placed where it says "no amplification". Can anyone help me? Thank you.

• Fix Nautilus URIs in a Python script

  - by Pablo

  I have a very basic Python script I wrote mostly for learning purposes. It opens a terminal in the current folder. However, I can't get it to work in folders with accented characters in the URI (e.g.: /home/pablo/Vídeos or /home/pablo/Área de Trabalho), because it looks like Nautilus URIs are encoded to those %{number} values. Is there a way to convert these URIs to normalized URIs without having to translate every possible accented value by hand? Thanks in advance!

• Resetting network adapter?

  - by Quixo

  I'm running Ubuntu 12.04. I get a strong wireless signal throughout my house, and the wireless symbol in the upper-right-hand corner shows that it's connected. The problem is, occasionally I am unable to access the internet (still having a strong symbol). This happened with Windows 7, too, but running the network troubleshooter fixed it each time. It claimed to be "resetting the network adapter". So, what I need to know is: How do I replicate that process on Ubuntu? Thanks for your help!
