• How do I cancel a time-delayed screenshot?

  - by coversnail

  I'm using the default screenshot application that comes with Ubuntu gnome-screenshot When I was using it earlier to take screenshots of the lock screen I had set a long time delay, but forgot to change it back after I'd finished. When I next took a timed screenshot I had to wait a long time for it to take because the delay was still set so long. Clicking the icon to relaunch the screenshot application has no effect whilst the timer is in effect, I imagine there is probably a simple terminal command to shut down an application, but I don't know it! Is there a way to do this?

• file copy error from system to cifs mount

  - by dwpriest

  When coping a file greater than 64kB from an Ubuntu server to a CIFS mounted windows share, most of the data is copied, but it seems the last chunk doesn't get copied. The size doesn't match, and the md5 check sums don't match. I have plenty of file space, but then I use cp, I get the following... cp: closing `cloudBackup/asdf.txt': No space left on device Using rsync, I get the following... rsync: close failed on "/home/fluffy/cloudBackup/.asdf.txt.qrBWe6": No space left on device (28) rsync error: error in file IO (code 11) at receiver.c(752) [receiver=3.0.8] rsync: connection unexpectedly closed (29 bytes received so far) [sender] rsync error: error in rsync protocol data stream (code 12) at io.c(601) [sender=3.0.8] I have full read/write permissions on the mounted share. I can copy locally and between the mount and system via SSH just fine. Any ideas? Thank you

• Stream audio to mobile device

  - by blackn1ght

  I'd like to stream the audio from Ubuntu 10.10 to my HTC Desire HD (Android 2.2). I've seen solutions so far for streaming from audio players, but I'd like to stream any audio output from the PC to my phone. My use case is for watching TV/Films in VLC or online (BBC iPlayer) in bed, without having to use my surround sound system which is likely to wake up my house mates. I'm not just talking about music from Banshee, but any audio that the system makes. I was thinking that PulseAudio is pretty powerful, is it possible to route audio through that to a mobile device? Can it be done through bluetooth? Cheers in advance!

• Wireless connection shows up but can't connect to internet with an Intel WiFi Link 5100

  - by Eddy

  I'm using an Asus G50V and I'm completely new to ubuntu. I just installed it and can connect to the internet with a wired connection and through wireless from my windows vista that I installed wubi on, and I can connect to my wireless network, but I can't actually connect to the internet through my wireless network. Thanks in advance. Network controller is an Intel Corporation WiFi Link 5100 according to lspci if that helps Also, the connection somehow started working after I decided to unplug my ethernet cable for the third time and headed upstairs after giving up for the day.. not sure how it happened, but after restarting, the connection stopped working again.. Wifi works on 11.10, but stops working when I upgrade back to 12.04..

• Fails to boot after upgrade, stuck on winbind package

  - by Praetorian

  I started the upgrade from 11.04 to 11.10 last night. Once it got the installing packages part I left the computer unattended the rest of the night. When I checked it this morning the screen was blank and I couldn't get it to turn on. So I cycled power, and now I get the "Ubuntu 11.10" screen with the dots underneath, but then it gets to a blank screen and nothing more. I can get to the command line in recovery mode; here's a list of the things I've tried so far sudo apt-get update - the very first repository it checked sat at 0% for a long time (network cable is plugged in), so I cancelled with Ctrl+C Thought it might be a problem with display drivers, so I tried sudo apt-get install nvidia-glx - this gave me an error saying dpkg has been interrupted, manually run sudo dpkg --configure -a sudo dpkg --configure -a this installed / updated a bunch of stuff but got stuck at Starting Winbind daemon winbind Restarted and tried sudo dpkg --configure -a again but it gets stuck at same Windbind step What else can I do to fix this problem?

• How to change Shift + <Keypad Key> behavior ?

  - by LeGEC

  I am used to use the numeric keypad for navigation (e.g. : [KP7] - Start, [KP1] - End, [KP4] - Left, etc... ). I am also used to use it for selection (e.g. : Shift+[KP7] - Select from cursor position to beginning of line, Shift+[KP1] - Select from cursor position to end of line, etc...) With the keyboard configuration installed with Ubuntu, though, Shift+[KP7] prints the character "7", Shift+[KP1] prints "1", etc... How can I change this so that Shift+[KP-key] is not mapped to [key], but to Shift+[KP-key] ?

• Error trying to install the Java SDK

  - by Ray

  I need to install the Java 6 SDK, but after running this: sudo apt-get install sun-java6-jdk sun-java6-jre sun-java6-source I end up with this: Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: sun-java6-jdk : Depends: sun-java6-bin (>= 6.26-1lucid1) but it is not going to be installed sun-java6-jre : Depends: sun-java6-bin (>= 6.26-1lucid1) but it is not going to be installed or ia32-sun-java6-bin (>= 6.26-1lucid1) but it is not installable Recommends: gsfonts-x11 but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). I'm quite new to Ubuntu and need the packages for my course. I guess they've become corrupted but, how can I fix this?

• System Error Report /usr/bin/Xorg

  - by jimirings

  I have recently begun getting a System Error Report message when I start up my computer. I haven't installed anything recently other than the usual updates or done anything else out of the ordinary. The details for the report just say "/usr/bin/Xorg". It doesn't seem to be causing me any problems beyond the annoying error message. I saw these questions regarding this problem: System Error Report - Xorg How do I enable or disable Apport? That's all dandy for getting the message to go away, but I'd rather fix the problem. Any ideas how I can make that happen? I'm running Ubuntu 12.04 on a Toshiba NB505. I am, of course, happy to provide any other relevant information that may be needed. Thanks in advance.

• Claiming the provisioned storage

  I created a ubuntu server vm with 64GB provisioned storage. I remember that I specified 30GB to be used for the vm.

• How can I solve display glitches and poor performance with ATI fglrx driver on my ThinkPad X100e?

  - by rewbs

  I noticed that video performance on my Thinkpad X100e was very poor compared to Windows 7, so I installed the ATI fglrx proprietary drivers by using the "Additional Drivers" dialogue box. The system has an ATI Radeon Mobility HD 3200 chip. The result of installing the drivers is pretty devastatingly negative, with symptoms such as skewed content in windows, browser tabs and text boxes failing to refresh when their content changes. In fact, please excuse typos in this post, because I can't really see what I am typing. :) I also notice that HD video playback performance is no better - perhaps even worse - than prior to installing the drivers. Example of what I see: Here's the output of fglrxinfo: display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: ATI Radeon HD 3200 Graphics OpenGL version string: 3.3.10237 Compatibility Profile Context Output of lspci | grep -i vga: 01:05.0 VGA compatible controller: ATI Technologies Inc RS780M/RS780MN [Radeon HD 3200 Graphics] I'm on Ubuntu 10.10 with kernel 2.6.35-22-generic-pae. What can I try? Many thanks, -R

• Terminal line glitches

  - by foxy

  I installed Ubuntu 11.10 mini + LXDE and wanted to make my command line different in terminal (than just plain white), so I added blue color to path line (everything until $ sign) and it works fine but I have two strange glitches now: When i write a line which is longer than terminal window, instead of starting at next line it starts at the same one, overwriting everything which was in there. Sometimes while navigating over previous commands (up/down arrow keys) some part of command gets stuck and is treated as part of prompt (the blue text), but it is white and is non-deletable and is not taken as part of command when i press enter. What could I mess up? The bad thing is that I don't remember what exactly did I change, but i'm sure I changed only one line in bashrc

• Samsung Series 5 overheating

  - by Sean Brad

  I bought a Samsung Series 5 Ultra 2 weeks ago and installed Ubuntu 12.04 LTS. I am experiencing problems with overheating. When streaming, watching a movie or when having several programms/actions going on at the same time the CPU temperature rises to 95 degrees and the computer freezes. This happens sometimes when the computer is on battery and always when it is recharging. When I am using the computer on battery the CPU temperature is floating from around 75-95 degrees depending what it's doing. When the battery is recharging the CPU temperature is ranging from 88-95 degrees no matter what tasks it performs. Have anyone experienced this and how may the problem be solved? Best regards

• How to reinstall many removed packages at once?

  - by Logan

  I used sudo apt-get remove python command and accidently removed a bunch of packages that were required. I logged in via command line and installed ubuntu-desktop again but there are other packages that are missing, and I'm looking for a way to easily reinstall those removed packages. Since there's the log at software-center I wanted to ask what the easiest way might be to roll back changes or extract the removed packages list from the software center... note: I typed sudo apt-get install .... .... ... ... for about two dozen of those removed programs in that list, but when I pressed enter it didn't install any of them because some package names couldn't be found. The programs were removed at the same date.

• Folder missing in external hard drive

  - by Hans

  I have been backing up my folders, I am using Seagate Expansion portable Drive. I had created a folder called "|o|o" in the root folder of the portable drive... I copied my latest folders into "|o|o" folder to re-install ubuntu. When I open the portable drive the folder |o|o is not visible, when I ctrl+a and check properties the space used is 122GB, however when I click on the drive to view properties of the drive used space is 260GB. It looks as if the folder is there in the portable drive but I cannot access it... I have tried to view all the hidden files and "|o|o" is still not there. I am using 12.04.Can you please help me to retrieve this folder.

• Graphics system failure

  - by anonymous coward

  I just upgraded two versions of Ubuntu to Oneiric after a recent set of updates broke Audacious 2.4.something in Maverick for me. When it was all finished my Asus Eee 1215N with the 1366x768 screen and the notoriously unsupported Nvidia Ion2 Optimus chipset was working on minimum compatibility fallbacks at 1024x768 resolution. So I did a little bit of reading (not enough) and tried deleting a couple parts of the graphics system to see if I could force a retry on the autodetection. The result: No graphical shell works now. Attempted so far: -reinstalling xorg/nouveau, didn't work. -installing bumblebee/nvidia-current, didn't work. -sudo dpkg-reconfigure -phigh -a, didn't work. I'd like to stress that this is otherwise a perfectly functional installation that I had spent some time setting up already (including a successful compile of Audacious 3.21 that was working with all the plugins). Is there a way for me to rebuild the graphics system from scratch or should I just give up, cry a little, backup data, wipe partition and reinstall with a USB drive?

• OpenSSL installed, but Ruby unable to require it

  I'm trying to setup github-pages on my Ubuntu laptop, and following the guide provided by Github I have to install the bundler package; giving the command ~$ gem install bundler returns me this error. ERROR: While executing gem ... (Gem::Exception) Unable to require openssl, install OpenSSL and rebuild ruby (preferred) or use non-HTTPS sources Then I have installed OpenSSL, launched the command to update software and stuff and tried again to install bundler, but the error kept showing. How can I fix this? Is there any specific command to rebuild ruby making it aware about the fact that openSSL is now installed?

• Command 'setenv' not found upon installation of Crystal09 program

• iptables -L lags on non localhost or anywhere address

  - by DazSlayer

  I am trying to configure iptables for ubuntu 10.04 and I have a problem with iptables -L lagging on rows where the destination or source address is not localhost or anywhere. The following entries will cause lag on their row: iptables -A INPUT -p tcp --dport 111 -s 192.168.1.14 -j ACCEPT iptables -A INPUT -p tcp --dport 90 -d 192.168.1.14 -j ACCEPT while this does not: iptables -A INPUT -p tcp --dport localhost -s 192.168.1.14 -j ACCEPT iptables -A INPUT -p tcp --dport localhost -d 192.168.1.14 -j ACCEPT I feel like this might be due to iptables checking to see if the ip is reachable. If not, what is the cause, if it is how can I disable it?

• Video Freezes Every few seconds

  - by Chandan

  Hi, I have problems playing videos on my Ubuntu 10.10 machine. The video FREEZES every 20-25 seconds, while I could still hear the audio. I use Totem Movie Player (GStreamer) & have nVidia on-board graphics card & AMD DualCore processor. After some 5-10 seconds, the videos resumes skipping the hung portion. But, I can hear the audio of that part! I've tried it with SMPlayer (GUI), VLC & Kaffeine. But, the same problem... I recently uninstalled the nVidia drivers and since then, not even for a second, no video hung! So, I thought its the problem with the proprietary nVidia drivers. But, since its uninstalled, I'm not able to get the desired desktop resolution & effects. So, is there any way I can work it out?

• Disable plugin in Firefox (acroread)

  - by cboettig

  I installed acroread from the repositories, and it has decided it should be the default plugin in Firefox, such that when I click on a pdf, it opens in a Firefox window. Unfortunately, it does not display (at least when in dual head mode). This should be simple, but I cannot disable the plugin. Under Firefox Edit - Preferences- Applications - pdf is set to "always ask" so I don't know why it uses acroread in the first place. Under Tools - Manage Content Plugins I see acroread is selected for pdf content. I have the option in the dropdown to search for a new plugin, but not to simply download the file. Typing about:config into the Firefox toolbar gives me a list of configuration options, but does not mention plugin.disable or acroread anywhere. How do I disable the plugin? I have Firefox 11.0 on Ubuntu 11.10

• Lost the config of my monitor once I connected it to a KVM switch.

  - by jfmessier

  I used to have a monitor (Acer 20", AL2017) connected to the external video port of my laptop. Everything was great and I could get a rather high resolution available when setting it under Ubuntu (all versions). But since I connected it to a KVM, the monitor is no more recognized, and I cannot go beyond 1024x768. My video adapter is an Intel chipset 9xx from an older Pentium Core 2 Duo laptop. The same monitor, using another video chipset (Intel 82G33/G31 rev 02) is properly detected through the switch box. Looks to me like the video chipset is not the best, and I can live with this. I see that I have no xorg.conf, and I understand that I would need to generate one so I can then use it to force the available modes on the X system. How can I generate the xorg.conf file for my Intel video chip, so I can use it then ? Merci :-)

• Installing chrome gives an error: "dependency is not satisfiable"

  - by Sled

  I just installed ubuntu on my laptop, everything works fine, but I'd like to use chrome instead of firefox. I downloaded the .deb file from the chrome website, and when I open it, the install buton inside the software center is inactive (I can't click it) and it's telling me dependency is not satisfiable: libcurl3 I did a search for libcurl3 in the Software Center, the three results I'm getting are already installed. Any ideas how to fix this? I also tried installing chromium-browser, but that's not working out neither. I'm getting Package dependencies not resolved and this details block: The following packages have unmet dependencies: chromium-browser: Depends: libgcc1 (>= 1:4.1.1) but 1:4.5.2-8ubuntu4 is to be installed Depends: libxdamage1 (>= 1:1.1) but 1:1.1.3-1ubuntu1 is to be installed Depends: zlib1g (>= 1:1.2.3.3.dfsg) but 1:1.2.3.4.dfsg-3ubuntu3 is to be installed Depends: libnss3-1d (>= 3.12.3) but it is not going to be installed

• why would Remmina stop working?

  - by Chris Curvey

  Until sometime last night, I had remmina working fine. I could run RDP through an SSH tunnel and all was well. Then it stopped working. I can get as far as the password dialog for my work machine, but then it just says "Cannot connect to RDP server localhost". I can't even find any logs that look interesting. I've re-installed remmina, cleared my .remmina directory, restarted my machine, and even restarted my gateway. Just to make it really weird, my laptop (which has the same setup -- latest Ubuntu and Remmina) can make the connection just fine. It is even going through the same router, albeit wirelessly. Any thoughts?
