  • Horible lag on Xubuntu media center setup

    - by William
    I am setting up a media center running Xubuntu 11.10 as a media center. It is using the XFCE desktop enviroment. I have the NVIDIA drivers installed from the Additional Drivers program, and uninstalled all but the esennitial software. The computer is a Dell Dimension 3000. You can view detailed technical specifications here. The graphics card installed is a Geforce 8400 GS. I have installed all updates through Update Manager. What can I do to fix the horrible lag? It makes watching TV impossible.I have uploaded two videos of the lag, here and here. The second one does not have sound because the sound stops playing on some channels that lag a lot. The TV card is a Hauppage 950q USB, and the TV recording program is Kaffiene. Please help me with this, I am trying to do this to show how great Ubuntu is to the rest of the family.

  • Parse git log by modified files

    - by MrUser
    I have been told to make git messages for each modified file all one line so I can use grep to find all changes to that file. For instance: $git commit -a modified: path/to/file.cpp/.h - 1) change1 , 2) change2, etc...... $git log | grep path/to/file.cpp/.h modified: path/to/file.cpp/.h - 1) change1 , 2) change2, etc...... modified: path/to/file.cpp/.h - 1) change1 , 2) change2, etc...... modified: path/to/file.cpp/.h - 1) change1 , 2) change2, etc...... That's great, but then the actual line is harder to read because it either runs off the screen or wraps and wraps and wraps. If I want to make messages like this: $git commit -a modified: path/to/file.cpp/.h 1) change1 2) change2 etc...... is there a good way to then use grep or cut or some other tool to get a readout like $git log | grep path/to/file.cpp/.h modified: path/to/file.cpp/.h 1) change1 2) change2 etc...... modified: path/to/file.cpp/.h 1) change1 2) change2 etc...... modified: path/to/file.cpp/.h 1) change1 2) change2 etc......

  • How can I calibrate my printer using the LaTeX test page?

    - by Chris
    I am trying to print a LaTeX compiled document but my printer doesn't print the top part. It seems that the top part is outside of the printing range. To debug this problem I have printed the LaTeX test page (/usr/share/texmf-texlive/tex/latex/base/testpage.tex) and it turns out that my printer is placing the content about 4.5mm closer to the top of the page than it should. How can I calibrate my printer/driver so that it will place the content where it is supposed to go? I am using an HP OfficetJet 7300 printer with hplip.

  • How do I stop Ubuntu Precise freezing/hanging

    - by artfulrobot
    At least once a day I lose work on my (2 different) Intel i5 machines running Ubuntu 12.04. The entire system will freeze/lock-up/hang, and never return. At this point nothing works; even the caps lock key doesn't toggle the light on the keyboard; Ctrl-Alt-F1 won't do anything either. askubuntu.com is apparently where I'm directed for support. I suspect this is a kernel bug. But I simply can't keep losing work like this, so I'm anxious to try whatever it takes to get the thing reliably working. Can you suggest something I can try to fix the problem an existing bug I can follow progress on and contribute to (from users/tester's POV) the most constructive way I can contribute to helping fix the problem, keeping in mind that I do need the computer (so can't do things that might "brick" it!)

  • How do I source a shell script for Node Version Manager?

    - by Matthew Patrick Cashatt
    Hi and thanks for looking! I am new to Linux/Ubuntu, but I have set up an Ubuntu box on which to run Node.js. I have had moderate success, but now I need to be able to easily upgrade my version of Node. Many folks recommend using Node Version Manager. I followed the directions, but when I try to do something like this: nvm ls I get a messaging stating that No command NVM found I have gone back to check the steps I followed to install NVM, but there is one part that is tricky for may and I think to be the culprit: sourcing the file for bash. From the instructions: To activate nvm, you need to source it from your bash shell . ~/nvm/nvm.sh I always add this line to my ~/.bashrc or ~/.profile file to have it automatically sources upon login. Often I also put in a line to use a specific version of node. So which file should I add this to? I am guessing profile since it's ubuntu?? Also, where in the file do I add this line? After I have added this line, do I need to reboot or anything? Any help would be deeply appreciated--especially if you can show me an example profile file with . ~/nvm/nvm.sh integrated so that I can see usage. Thanks, Matt

  • Ubuntu scrollbars don't render on Cygwin X server

    - by David M. Karr
    I have an ubuntu 12.0.4 desktop. I have a Win7 laptop running Cygwin. I can display windows from the Ubuntu box on the Win7 laptop using the Cygwin X server, but the window is somewhat "degraded". Specifically, scrollbars are not rendering properly. I've used Ubuntu before, but this is the first time I've seen these odd scrollbar popups that are used in 12.04. I'm guessing the Cygwin X server is having trouble rendering that for some reason. In the Cygwin view, I see the slightly thicker vertical bar, but when I hover the mouse over it, nothing happens. I'd really prefer to get conventional scrollbars. Can I configure Ubuntu 12.0.4 to do this, which might result in Cygwin being able to display them?

    To whoever can help, I want to update the ubuntu on my laptop to 12.10 from the current version 11.10, when i click on the update manager i get a partial update gui, if i click cancel on that i get the gui for update which has three buttons check, install updates and upgrade.

  • Using shortkeys to search the internet for a term selected in a text editor/viewer

    - by cipricus
    It seems possible (as I learned from a comment to this question made by user55822) to use a command in order to search a term on the web by using "keybinding" the way Aretha is used. What the aforementioned user says is that "you could search mouse selection anywhere by using an app like Artha, or by keybinding sh -c 'firefox "http://translate.google.com/#en/fr/$(xclip -o)"' (example given translate english into french)" A lot of things are obscure for me here. I could use Artha or keybinding (as alternative), or both? How to do that in each case? and "The command I gave you will open google translate in Firefox with your mouse selection (text highlighted) as a query. Use sh -c 'firefox "https://www.google.com/search?q=$(xclip -o)"' if you want regular Google over Google translate. And obviously, that would work everywhere" I do not know what to do with that formula. What should I do exactly? How to use it? In what application?

  • Ubuntu 12.10 desktop/interface not showing on VirtualBox VM after login screen

    - by Jake
    I'm having some trouble with getting my Ubuntu to work on a VirtualBox VM. I made a clean installation of Ubuntu 12.10 on a VM without any errors. I arrive at the login screen, as soon as I press enter it does it's little loading thingy and then screen goes black, then this is all I get: http://i.imgur.com/zULUI.jpg I can access the terminal and pretty much all the other features through it, but I would like to have the GUI properly working. I've been looking around the web and looking at various fixes to similar problems, but can't seem to get it to work. I'm thinking this problem might have to do with the graphics? I'm running Windows 8 Pro as host, if that helps, might be some compatibility issues with VirtualBox in W8... Thanks in advance!

  • Need help with xorg.conf for dual Radeon HD6450 video cards with 4 monitors

    - by Eriks Goodwin-Pfister
    I am running 64-bit Ubuntu 13.10 with Unity and have dual (2) Radeon HD6450 video cards and 4 Hanns-G HL273 monitors. Each Radeon card is driving one monitor via DVI and the other via VGA. I am running the proprietary video drivers from AMD's web site: "amd-catalyst-13.11-beta V9.4-linux-x86.x86_64.run" I tried to use "amd-catalyst-13.12-linux-x86.x86_64.run" but could not get that newer version to install. What I need help with is how to "correct" my xorg.conf file and any other needed instructions to get all four of my monitors to work as a continuous desktop that allows me to drag things from one monitor to the next, etc. When I tried to use the default open source drivers that came in Ubuntu 13.10, only three of the monitors would work. Now that I am running the proprietary ones, all four monitors come on and I can move my mouse from one end to the other--but only the right-most monitor displays my desktop and allows me to "do anything". Any time I move my mouse to any of the other three monitors (which display all-white), it turns into an "X" and does not do anything else but move. Enabling xinerama makes all four displays go all-black after login. I do have amdcccle installed, but it does not seem to have the ability to handle my particular configuration. My Current xorg.conf: Section "ServerLayout" Identifier "Basic Layout" Screen 0 "Screen1" 5760 0 Screen 1 "Screen0" 0 0 Screen 2 "Screen2" 3840 0 Screen 3 "Screen3" 1920 0 EndSection Section "Module" EndSection Section "Monitor" Identifier "0-DFP2" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "PreferredMode" "1920x1080" Option "TargetRefresh" "60" Option "Position" "0 0" Option "Rotate" "normal" Option "Disable" "false" EndSection Section "Monitor" Identifier "0-CRT1" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "PreferredMode" "1920x1080" Option "TargetRefresh" "60" Option "Position" "0 0" Option "Rotate" "normal" Option "Disable" "false" EndSection Section "Monitor" Identifier "1-DFP2" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "PreferredMode" "1920x1080" Option "TargetRefresh" "60" Option "Position" "0 0" Option "Rotate" "normal" Option "Disable" "false" EndSection Section "Monitor" Identifier "1-CRT1" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "PreferredMode" "1920x1080" Option "TargetRefresh" "60" Option "Position" "0 0" Option "Rotate" "normal" Option "Disable" "false" EndSection Section "Device" Identifier "Device0" Driver "fglrx" Option "Monitor-CRT1" "1-CRT1" BusID "PCI:1:0:0" EndSection Section "Device" Identifier "Device1" Driver "fglrx" Option "Monitor-DFP2" "0-DFP2" BusID "PCI:4:0:0" EndSection Section "Device" Identifier "Device2" Driver "fglrx" Option "Monitor-DFP2" "1-DFP2" BusID "PCI:1:0:0" Screen 1 EndSection Section "Device" Identifier "Device3" Driver "fglrx" Option "Monitor-CRT1" "0-CRT1" BusID "PCI:4:0:0" Screen 1 EndSection Section "Screen" Identifier "Screen0" Device "Device0" DefaultDepth 24 SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "Device1" DefaultDepth 24 SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" Identifier "Screen2" Device "Device2" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection Section "Screen" Identifier "Screen3" Device "Device3" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection

  • USB device is recognized but has no address

    - by SeanMG
    Good day folks, I'm trying to use a USRP1 with GNURadio if anyone knows what any of that is. I am running Ubuntu on a Windows 7 machine via VMware player. When I connect this USRP1 via USB 2.0 drive to Windows 7 it is recognized as Ettus Research LLC USRP1... When I connect the device to Ubuntu through VMware, it shows: usb device fffe:0002 on my removable devices. When I run lsusb I receive the following: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID 0e0f:0003 VMware, Inc. Virtual Mouse Bus 002 Device 003: ID 0e0f:0002 VMware, Inc. Virtual USB Hub Bus 001 Device 004: ID fffe:0002 When I run this program that comes with the USRP driver... uhd_find_devices I receive: -------------------------------------------------- -- UHD Device 0 -------------------------------------------------- Device Address: type: usrp1 name: serial: 00000000 So when I run this program, it does recognize the fact that this device is connected. However, the device has no address, no name, and has a null serial. I need to know the device address so I can run more programs in GNURadio. Does anyone know what the problem is here? Thanks!

  • Resize Partition with gparted

    - by arian
    I wanted to create more space for Ubuntu on my hard disk in favor of my windows partition. I booted the livecd and resized the ntfs partition to 100gb. Then I wanted to resize my ubuntu (ext4) partition to fill up the created unallocated space. A screenshot of my current disk. (With the livecd there's no 'key' icon after sda6) My first thought was just right click on sda6 ? move/resize ? done. Unfortunately I cannot resize or move the partition. However I can resize the ntfs partition. I guess it is because the extended sda4 partition is locked. I couldn't see an unlock possibility though… So how do I resize the ext4 partition anyway, probably by unlocking the extended partition, but how? Thanks in advance.

  • Games installed from repos won't start

    - by Shauna
    I'm running Natty (upgraded from Maverick) with Gnome 3 (from the Gnome 3 PPA, Unity removed), and have recently found that some of my games from the repos no longer work. When I go to start them, I get the message Failed to launch [app name]. Failed to execute child process [app name] (no such file or directory). I've so far found this on Gweled and PyScrabble. Other games (Mines, Sudoku, Mahjongg), as well as other applications have opened just fine. Gweled used to open fine until recently. Any ideas on how to fix this?

  • How to associate all file types within Wine with its corresponding native application?

    - by MestreLion
    This is easily done for a single file type, as answered in How to associate a file type within Wine with a native application?, by creating a .reg for the desired filetype. But this is for AVI only. I use some wine apps (uTorrent, Soulseek, Eudora, to name a few) that can launch a wide range of files. Email attachments, for example, can be JPG, DOC, PDF, PPS... its impossible (and not desirable) to track down all possible file types that one may receive in an email or download in a torrent. So I neeed a solution to be more generic and broad. I need the file association to honor whatever native app is currently configured. And I want this to be done for all file types configured in my system. I've already figured out how to make the solution generic. Simply replacing the launched app in .reg for winebrowser, like this: [HKEY_CLASSES_ROOT\.pdf] @="PDFfile" "Content Type"="application/pdf" [HKEY_CLASSES_ROOT\PDFfile\Shell\Open\command] @="C:\\windows\\system32\\winebrowser.exe \"%1\"" Ive tested this and it works correctly. Since winebrowser uses xdg-open as a backend, and converts my windows path to a Unix one, the correct (Linux) app is launched. So I need a "batch" updater to wine's registry, sort of a wine-update-associations script that I can run whenever a new app is installed. Maybe a tool that can: List all Mime Types types in my system that have a default, installed app associated Extract all the needed info (glob, mime type, etc) Generate the .REG file in the above format The tricky part is: i've searched a LOT to find info about how association is done in Ubuntu 10.10 onwards, and documentation is scarce and confusing, to say the least. Freedesktop.org has no complete spec, and even Gnome docs are obsolete. So far I've gathered 4 files that contain association info, but im clueless on which (or why) to use, or how to use them to generate the .reg file: ~/.local/share/applications/mimeapps.list ~/.local/share/applications/miminfo.cache /usr/share/applications/miminfo.cache /etc/gnome/defaults.list Any help, script or explanation would be greatly appreciated! Thanks!

  • How do I get wireless and video working on a Sony Vaio vpc-z21x9r

    - by Alex
    OS: Ubuntu 11.10 Kernel: 2.6.37.6 Laptop: sony vaio vpc-z21x9r The problem: I can't change level of screen backlight; also can't enable wi-fi. While using 3.0 kernel everything is ok, but the laptop discharges too quickly. Results for lspci 02:00.0 Network controller: Intel Corporation Centrino Wireless-N + WiMAX 6150 (rev 5f) VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) there is no wlan0 in ifconfig -a too. I've fount that kernel should already have drivers for this graphics controller, but when i load up in restore mode, it writes "fall" while trying to load up some video drivers. To change the level of backlight i've alrady tried: xbacklight -set XX , smartdimmer -s XX and got this init_ nvclock() failed! also sudo setpci -s 00:02.0 F4.B=XX with no results. As for wi-fi, i've found driver but i don't understand how to install it. Here it is How can I fix these problems? Thank you for your help and time! Also tried to fix problems with backlight writing GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset acpi_backlight=vendor Still no results. Is there any sense in recompiling kernel, I mean 2.6.37.6. Can it make any improvements in the situation?

  • How can I figure out why Suspend sometimes fails?

    - by Isaac
    Something is causing suspend crash occasionally. When it does crash, the system freezes with a black screen and stays on, not suspending. This makes me have to hold the power button until the system shuts down. One setting difference I have from most people is, I don't use the option that lets you suspend when the laptop lid is closed. So opening and closing the laptop lid has no actions. I like to press suspend manually. Could this preference change be the cause? How can I start looking for what's causing the crash, since the crash doesn't display errors?

  • Is the wireless driver from Live USB different from the standard install?

    - by Rafael Magalhães
    Linux newbie here. I've been trying to use Ubuntu (x64) as my main OS since 11.10, but my wireless connection on it has been very unstable, droping every other 5-10 mins. For this reason I see myself forced to use Windows 7 (dual booting), where connection works flawlessly -- which really bothers me. My card is an Atheros 9k, which claims a reasonable amount of wireless complaints on Ubuntu forums. I've tried every suggestion given on past questions to this site but to no avail. However, while running Ubuntu Live USB for some of the tests, I noticed that my wireless connection never failed on it and wondered if its network configuration differs from the one on the default Ubuntu install. If this is the case, how could I reproduce the Live USB network environment on my hard drive install?

  • Why must I restart for HDMI audio?

    - by David Shochat
    I have a System76 Lemur Ultra laptop, which has an HDMI port. When I plug in the HDMI cable, it is recognized immediately for video, but not for audio, i.e., it does not show up in the Output tab of the Sound Settings dialog. However, if I do a full restart with the cable plugged in, then it does show up and can be selected. I've also discovered that manually killing and restarting pulseaudio with the HDMI plugged in will force it to be recognized as an available audio output. So my question is, what is broken here? I've thought about writing a bug in launchpad, but I don't know which component is malfunctioning. Is it the kernel? ALSA? Pulse Audio? Something else? By the way, the same bug seems to exist in reverse, namely if I disconnect the HDMI, it is still listed in the Output tab until I again restart the OS. This is 12.04 LTS.

This Windows software here solves the problem. Anything comparable available for me on Ubuntu? PS: at first I thought it was a file creation date problem askubuntu question. But although I figured out the answer to that question, it didn't solve the problem like I thought it would.

  • Internet Timeouts with TP-Link TL-WN821N wireless usb stick - existing solutions dont work

    - by Sheena
    I'm running Ubuntu12.04 and I'm trying to get a TP-Link TL-WN821N to work. The solution from Internet Timeouts with TP-Link TL-WN821N v2 wireless usb stick didn't work for me. Neither has anything else... I've installed rtl8192cu as per instructions I found elsewhere to no avail. The symptoms I am experiencing are: When I plug in the device the PC can see and connect to wireless networks fine. The network I'm using has internet access and the signal strength is pretty strong. I can't ping and I can't browse the internet (timeout). Any ideas? I'm not sure what the next step would be or what information would be useful at this point.
