  • All video players display black screen.

    - by Dennis
    I'm working in 10.04 Lucid. All my video players (Movie Player and VLC) and the preview windows in editors (OpenShot and Pitivi) will only display a black screen when playing a video. The sound is fine and the videos work fine on other computers. I have tried multiple formats from varying sources .MOV taken from old ffmpeg projects, .AVI straight from a camera, .MP4 using h.264 from OpenShot on another system, .OGV from a gtk-recordmydesktop session on this very computer. I even get a pure black screen in the viewer when starting a remote session in VNC. This box has a GeForce 8400 GS using the Nvidia drivers in case it may be a card problem or setting.

  • print jobs are held until the VirtualBox guest OS is reboot

    - by broiyan
    Here is the setup: VirtualBox 4.1.20 (which the Help window describes as 4.1.12_Ubuntu) Extension Pack 4.1.20 (for USB support) Windows 7 Home Premium as a guest operating system on VirtualBox Ubuntu 12.04 with dist-upgrade's to September 2012 as the host operating system. Fuji Xerox DocuPrint P205b, which I believe is a GDI printer, connected via USB. The problem is that often print jobs will sit in the print queue and nothing comes out of the printer. The printer status for the first item in the queue will be Printing even though nothing happens. Then upon rebooting Windows, the print jobs get printed, seemingly simultaneous to the rebooting process; that is as Windows reloads. One way to avoid this problem is to reboot Windows with the printer cable attached, and then submit the print jobs. The print jobs get printed in a timely manner. Perhaps VirtualBox has a problem with USB being plug-n-play and hot pluggable. It's not convenient to have the printer plugged in when Windows boots because: One, this is a laptop, and Two, I may be boot Windows for a purpose other than printing and not anticipate needing to print. Are there any recommendable fixes for this problem?

  • OpenVPN is installed but it is not an avaliable option in the network manager

    - by Relik
    I have installed and used openVPN once before in a previous install of Ubuntu 12.04. I have since reformatted, and now after reinstalling openVPN it will not show up in the network manager. I am trying to setup my VPN connection and the only option I have to choose from is PPTP. EDIT: I have Gnome Shell and KDE installed as well, Gnome being my primary. I cannot find OpenVPN in either Gnome or Unity, however I can add it without an issue in KDE. Not really an acceptable workaround, but it works for now. I would still like to be able to do it in GTK based desktops as well.

  • Cannot set Chrome as default browser

    - by user1951615
    This has been asked before but there is no answer that works for me. The last answer I saw said to use System Settings. If I look there (Details, Default applications, Web), it says that Chrome IS my default browser. But every time I launch Chrome, it asks me again. If I look within Chrome under Settings, Default Browser, it says that it is not the default browser. There is a large button marked "Make Google Chrome the default browser" but, as someone else as already reported, this button has no effect. I am on the stable channel for Chrome. I tried making a comment to the existing thread but was unable to. That is why I am asking as a new question.

  • How to enable mnemonics in 12.04 and/or 14.04 GTK3?

    - by jmunsch
    Word on the street is that "gtk-enable-mnemonics" has been deprecated since version 3.10, and I am not at all sure how to get my application to display mnemonics. They will only display if I press the alt key. Please see here: http://stackoverflow.com/questions/23049406/wxpython-button-shortcut-accelerator-how-to-spam I have tried everything suggested in this article in regards to settings.ini, switching the bool to the opposite: How do I disable mnemonics in GTK3?

  • What's up with all the updates? [closed]

    - by Bob Babb
    I use Ubuntu exclusively for my job, especially for the fact that everything works and I get the most out of my processor and memory, but you are killing me with updates! I just lost a very good opportunity from a client that installed Ubuntu but got tired of all the updates. I really can't argue the fact. In a matter of a day I had two software updates. Quote from customer: "It's sad that I come in at 6:00 in the morning to install updates from a LTS version, and then before I leave at the end of the day I have 19 new updates to install. At least Microsoft bundles them in controllable groups." Sadly I have to agree, guys you have to do something about this. Please!

  • USB Audio Device Loopback Through Speakers

    - by matto1990
    I have a USB turntable which when plugged in to my ubuntu 10.10 machine appears in the audio settings as an input device (USB PnP Audio Device Analog Stereo) like a microphone. What I'd like to be able to do it to have the sound for that audio device played back through the audio output (speaker or whatever). I'm not too worried if there's a slight delay between the audio coming in and it being played out through the speakers. As far as I'm aware this is refereed to as software loopback. I can achieve exactly what I want if I open Audacity, enable software loopback and press record. Obvious this isn't ideal as I don't really want it recording what I'm playing all the time. I know this is possible because of the Audacity example however I'd like to know if there's a way to do it without it recording. I've search around for a while for a piece of software that does this, however I couldn't get anything even close. Any help would be greatly appreciated.

  • Getting vga_switcheroo with ATI Mobility Radeon 5650 HD to work

    - by stevejb
    Hello! I have a new HP dv7 laptop with ATI Mobility Radeon HD 5650 graphics card, and also Intel graphics (switchable). I have done the following and want to understand what is going on with my graphics driver Resized windows 7 and did fresh install of 10.10 Booted into 10.10 and things seemed to be working okay Enabled ATI graphics, and was clearly working on the ATI rather than Intel GPU (desktop cube worked) Rebooted, got an error that modprobe could not load modules.dep, and also something about i915 symbols Rebooted into recovery mode, modified xorg.conf to remove the mention of fglrx Rebooted, and the errors show, but then x starts but clearly in intel graphics I would ideally like to be able to switch between the ATI and Intel graphics, a la vga_switcheroo. My first problem seems to be that the folder /sys/kernel/debug/vgaswitcheroo does not exist, hinting at some kind of kernel issue. What can I do to get this available? Thanks!

  • Very High CPU usage (100%) from just browsing the Web

    - by cole
    I tested on Firefox and Chromioum. Im at 100% while loading pages which causes them to load slow and when I dont have a application running Im at 40% CPU (At least) Everything is slow basically. Im also already on Ubuntu Classic so im not using Unity. Should I go to 10.04? is that more stable? On windows this wasnt an issue. I have a Dual Boot with XP and a 2.4Ghz Intel Celeron with 768MB RAM and an Nvidia 6200 Graphics card. I heard 10.04 was the most stable. any suggestions?

  • Setup CRON weekly backup

    - by sadmicrowave
    I want to make a backup of my /var/lib/mysql and /var/www folders and save them as tar.gz files to my mounted network file server (uslons001). Here is my bash file located in: /etc/cron.weekly/mysqlbackup.sh #!/bin/bash mkdir ~/uslons001/`date +%d%m%y` tar -czf ~/uslons001/`date +%d%m%y`/mysql.tar.gz /var/lib/mysql tar -czf ~/uslons001/`date +%d%m%y`/www.tar.gz /var/www tar -czf ~/uslons001/`date +%d%m%y`.tar.gz ~/uslons001/`date +%d%m%y` echo Backup Completed `date` >> ~/backuplog Which works PERFECTLY fine when I execute it in a cmd shell but when I setup the cron job it never runs, so I'm not setting the cron job up properly. My cron job looks like this. 30 7 * * fri /etc/cron.weekly/mysqlbackup.sh Which should execute at 7:30AM every Friday... What am I doing wrong? UPDATE1 - change the cron job line to the following: 44 8 * * 5 /etc/cron.weekly/mysqlbackup.sh with still no luck...is there a cron error log file that I can read to help pin point where the problem is?

  • Configuration server problem after changing /tmp mountpoint: how to solve?

    - by Aron Rotteveel
    I created a new partition on my hard drive because my /tmp partition was too small. I changed the mountpoint in /etc/fstab and rebooted. Every time I reboot, I get the following error message at the login screen: There is a problem with the configuration server. (/usr/lib/libgconf2-4/gconf-sanity-check-2 exited with status 256) When I log in, /tmp is mounted correctly and everything seems to work fine. When I reboot, the error shows again. When I change the /tmp mountpoint back to the old partition, the error message disappears. What could be causing this and how can I solve this issue?

  • Does Unity support disabling the global application menu?

    - by Michael E
    I'm fairly excited for Unity, as it looks like a promising new direction for Ubuntu. However, I do have a concern - will it be possible to use Unity without the global menu? I have my window manager set to focus-follows-mouse/sloppy focus, and find the productivity gains to be immense. Sloppy focus is incompatible, however, with global menus, as it is possible for the focus to change while you move from window to menu. Will Unity support an option to use window menus while still using Unity?

How in Launchpad i can find from my bugs: Motherboard HDD Somthing else that can help identify it Maybe how to recover or find some overwritten files (couse now there is windows) I found in Launchpad one my bugs has LSPCI autogenerated from bug 682846 https://launchpadlibrarian.net/70611231/Lspci.txt but i dont see any id that can be used to identify specificly my comp.

  • Are any Zotac Zboxs suitable as HTPC / media centres?

    - by Jakub
    Are any Zotac Zboxes suitable as HTPC / media centres? I'm after a fanless HTPC client in the living room to work with my MythTV server in my home office. I like the small compact form factor of the Zbox but what little I could find by Googling didn't clearly recommend any particular models for Ubuntu / MythTV / XBMC. Can anyone recommend any models that work with little hassle? Or, if there aren't any, are there other more Linux-friendly small format fanless PCs I should be looking at instead?

  • Installed LibreOffice 4 with ppa, how do I remove it and go back to LibreOffice 3?

    - by MMA
    EDIT This question is not at all a duplicate of How to downgrade from LibreOffice 4.0 to 3.6? The above mentioned question talks about downgrading from a specific version of LibreOffice, namely from 4.0 to 3.6. The solutions mentioned are not the ones I am looking for. They will work but I wanted a general solution without using PPA or downloading .deb files for from a higher version to a lower version. The above solutions suggest either downloading .deb files for LibreOffice 3.6 or adding repository for it. Furthermore, some of the answers put out-of-proportion~(applicable for the solution, however) stress on use of synaptic, not general command-line-solution. That made me wonder, at this very moment, if I take a fresh computer, and install Ubuntu 12.04, LibreOffice installation will work without a hitch. Then why I can not install LibreOffice in my 12.04 machine today from simple command line? This answer to my question, clarified everything. I need to use ppa-purge so that this resets all packages from a PPA to the standard versions released for my distribution. Basically it is like a way to restore my system back to the way it was before my installed packages from a PPA. This article further elaborates the idea. The above mentioned answer worked perfectly for me. Actually, this was an education for me since it taught me how do downgrade a package that was added via PPA. I had upgraded from LibreOffice 3 to LibreOffice 4 using the PPA. Now since I found that LibreOffice 4 has some issues, including handling my native language, I want to move back to LibreOffice 3. In order to accomplish this, I removed the LibreOffice config directory from my home and then purged LibreOffice from my machine. sudo apt-get purge libreoffice-* Then I removed the relevant PPA's using the sudo apt-add-repository --remove command. And then ran sudo apt-get update. Now, when I try to install LibreOffice using the command sudo apt-get install libreoffice I get an avalanche of output about unmet dependencies, something like, The following packages have unmet dependencies: libreoffice : Depends: libreoffice-core (= 1:3.5.7-0ubuntu4) but it is not going to be installed (snipped) If I dig the issue further, by using the command, sudo apt-get install libreoffice-core I get The following packages have unmet dependencies: libreoffice-core : Depends: libreoffice-common (> 1:3.5.7) but it is not going to be installed Depends: libexttextcat0 (>= 2.2-8) but it is not going to be installed Depends: ure (>= 3.5.7~) but it is not going to be installed E: Unable to correct problems, you have held broken packages. Could you please tell me how do I install LibreOffice 3 in my machine? I am using Ubuntu 12.04 LTS.

There was a point when i was prompted for the "encryption password" but i don't remember it, so i just entered one. I never got any error if the password i entered was not accepted.

  • Problems with Maverick upgrade

    - by altenuta
    I upgraded to Maverick 10.10 from Lucid. I have an old Toshiba Satellite with a 1.1 MHz and 256MB RAM. Initially I couldn't get my wireless to work. That solved itself after installing various updates and programs. The problems that remain are: I have to authorize at least 2 times at start-up. This machine is Ubuntu only. No boot load screen. I have a ton of programs and system directories that are in my home folder. Is this normal? It is difficult to wake the computer from sleep. Usually I just shut it down and restart. Tonight I waited and got a message about corrupt memory. The computer takes forever to do just about everything. Slow to start programs or doing things on the web. I am a longtime Mac user (since 1986). I also manage a network of several windoze machines. I am definitely a GUI guy and do very little in the terminal so I really need to know where to begin to get things straightened out. Can I rescue this machine without wiping it and doing a fresh install? This is basically a hobby machine. Aside from all the programs and upgrades I've installed, I have almost no files or documents to worry about saving. Anyone have any ideas about the problems I'm having and the best way to proceed? Thanks, Al

  • Fix Windows MBR using Ubuntu Live CD

  • MathType and LibreOffice Math comparison

    - by Agmenor
    In my office my team and I are going to type texts in the future which will include mathematical signs. Two programs are being proposed: LibreOffice Writer + Math or Microsoft Office + MathType. I would like to advocate for the first solution, but I need to know what technical advantages and disadvantages each program has. Compatibility with Ubuntu is an evident and important characteristic for LibreOffice, but could you give some other aspects? As a side question, do you advice any other program, even if not WYSIWYG and thus not my preference in this case?

Later I tried installing it from USB using UNetbootin and also Universal USB installer but both in vain. Can someone please tell me what wrong am I doing or what else needs to be done. I am using a Toshiba pen drive 4Gb. I tried booting from the rescue mode but again had the same problem. Would be great if someone helps me out ASAP. Thank you( for reading as well as for helping).

  • How do I re-enable the backlight?

    - by Scott Severance
    Since Oneiric, if I leave my machine (HP Mini 110 netbook) unattended and it goes into power-save mode, the backlight gets disabled. How can I turn it back on? Note that the keyboard backlight controls (Fn+F4 and Fn+F3) don't have any effect in this situation. I've already filed a bug, but filing a bug doesn't fix my problem. I tried this workaround posted in this bug report dealing with Acer laptops: sudo setpci -s 00:02.0 F4.B=0 However, if anything, that command makes things worse. In the general case, I can see a little bit if I'm in a dark room with a flashlight aimed just so. But after running setpci I can't see anything. And I find the setpci documentation to be utterly incomprehensible, so I don't know whether I need to tweak my command somehow or whether I'm completely barking up the wrong tree. Update: I've found a workaround: I'm now booting with the kernel parameter acpi=off. This disables power management, which prevents the machine from going into power saving mode and thus failing to come back up correctly. Of course, not having power management means that I can't use suspend or do anything to manage power other than powering it off (even then, I have to manually use the power switch). Also, it prevents me from using Unity 3D or Gnome Shell, forcing me into Unity 2C or Gnome Classic. So, I'd really like to be able to stop using this hack.

  • Connect to bluetooth device from command line

    - by Ilari Kajaste
    Background: I'm using my bluetooth headset as audio output. I managed to get it working by the long list of instructions on BluetoothHeadset community documentation, and I have automated the process of activating the headset as default audio output into a script, thanks to another question. However, since I use the bluetooth headset with both my phone and computer (and the headset doesn't support two input connections) in order for the phone not to "steal" the connection when handset is turned on, I force the headset into a discovery mode when connecting to the computer (phone gets to connect to it automatically). So even though the headset is paired ok and would in "normal" scenario autoconnect, I have to always use the little bluetooth icon in the notification area to actually connect to my device (see screenshot). What I want to avoid: This GUI for connecting to a known and paired bluetooth device: What I want instead: I'd want to make the bluetooth do exactly what the clicking the connect item in the GUI does, only by using command line. I want to use command line so I can make a single keypress shortcut for the action, and would't need to navigate the GUI every time I want to establish a connection to the device. The question: How can I attempt to connect to a specific, known and paired bluetooth device from command line? Further question: How do I tell if the connection was successful or not?
