  • help bonding streaming rtp 3g

    - by enrique
    first sorry for contact me here. Recuro to you after reading all the material I found about it and so it does not get set. My question is: I can configure load balancing in any way out? I have a hub with 3 USB 3G modems, I got the 3 simultaneously connect with an upload speed of about 500kb in each approx. and a dynamic ip each. I do a unicast streaming with vlc rtp with a bandwidth of 1.5mb. Bone the sum of the three modems. I was searching on ifenslave, iproute. Then I found a draft vlc MultiCat. I understood that this could end, but configure it only moves a card. If I can help extend the information willingly. From now eternally grateful.

  • How do I get the Netgear N150 USB wifi adapter working on 12.04?

    - by Jon
    Just installed latest version of ubuntu. I'm using a Netgear N150 Wireless USB Micro Adapter WNA1000M which keeps asking for network password over and over. I read elsewhere that I needed to install the latest driver for my chipset (RTL8188CUS) which I have and still no joy. If I run the steps listed in this thread while connected through ethernet, the wireless will connect just fine. If I disconnect the ethernet, the wifi will even continue to work, but after a restart or two I will lose connection. If I repeat the steps listed in the aforementioned thread, it will not re-connect wifi unless I run those steps while connected to ethernet.......so strange...

  • Confused about what makes up the Ubuntu GUI

    - by RafLance
    I am now getting more into customizing my Ubuntu experience and want to understand better what all these different things I keep running into are. What is Gnome3 and Gnome2 in relation to GTK3 or GTK2? Are they related at all? Is Gnome3 another version of Unity? What is Unity? What is compiz? To make this all VERY basic, the core question is: How is the Ubuntu GUI built? What are the elements from the bottom-up that make up the desktop environment? Trying to understand this better so I know what I need/want in order to have my desktop the way I would like it. If this question is better suited for a forum of some sort, please let me know and I will understand completely. Thanks in advance!

  • glx not working, optirun works, gnome in fallback mode

    - by user26766
    It all started when I installed nvidia's own driver. Uninstalling it and reverting back to nvidia-current didn't solve the problem, so I have been playing with this for a while. Now nvidia-current seems to be functional. It seems glx support is missing, and my intel graphics is not responding. gnome loads only in fallback mode. Here are some outputs: glxinfo name of display: :0.0 Error: couldn't find RGB GLX visual or fbconfig glxgears Error: couldn't get an RGB, Double-buffered visual optirun glxgears works fine lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M] (rev ff) how can I fix this? thanks,

  • Why does Compiz keeps crashing?

    - by odeh86
    I am running Ubunutu 14.04 x86_64. Compiz keep crashing frequently and I can't work on my laptop. If I have media running or so I can still hear the audio and its just Compiz that is crashing as I see in some crash logs. I tried to reset both Compiz and Unity but still it is not working. Is there a solution or should I jump back to Gnome? Here are the commands that i tried:- dconf reset -f /org/compiz/ unity-reset setsid unity

  • Windows Repairs Itself After Ubuntu Boot

    - by pjtatlow
    I have a custom built computer in my home which was running Windows 7 primarily. After I installed Ubuntu 12.04 and upgraded to 12.10, Windows 7 has to perform startup repair after every Ubuntu boot up. For example, I am using Ubuntu for my everyday work, but when I switch to Windows to play one of my steam games, windows fails to boot, and it switches to the recovery partition to "repair windows" then boots windows. The whole process takes about 20 minutes, which is quite annoying. Anyone know why this is happening or what I can do? Thanks in advance!

  • Ubuntu12.10 not installing on new computer?

    - by Joshua
    I'm trying to Install the latest 12.10 Desktop. I have burned the iso file onto a DVD using an ISO burner. I then reboot my computer, and use the boot menu, I choose the DVD and it asks me if I want to try it, install it, or check for defects. Whichever one I choose my screen goes blank and for a bit you can hear my DVD burner, but then it stops and the screen goes completely blank and doesn't so anything. I am using a new HP Pavilion model P7-1455 running windows 8. What is wrong? How can I fix this?

  • How do I create a new usergroup?

    - by Sergiu
    I want to do this because I'm trying to fix user permissions from Ubuntu on my Mac OS X partition and Ubuntu doesn't have the "wheel" group that I so desperately need! Please don't trash me for this but I set my whole Mac OS X partition to give read and write access to everyone so I could access and modify everything on it from my dual-booting Ubuntu OS, and now everything is screwed... I don't have the original Mac OS X installation DVD and booting a Mac OS X 10.5.6 DVD gives me kernel panics... The OS installed on that Mac partition is 10.4.11. Is there any hope for me to ever fix it? I don't have money to buy utilities, and I can't use AppleJack either because my permissions are so messed up... None of the posted answers are what I wanted to do. I wanted to add fields to a user that was on my Mac partition, not a user part of the Ubuntu groups. Is that possible?

  • How would I batch rename a lot of files using command-line?

    - by Whisperity
    I have a problem which I am unable to solve: I need to rename a great dump of files using patterns. I tried using this, but I always get an error. I have a folder, inside with a lot of files. Running ls -1 | wc -l, it returns that I have like 160000 files inside. The problem is, that I wish to move these files to a Windows system, but most of them have characters like : and ? in them, which makes the file unaccessible on said Windows-based systems. (As a "do not solve but deal with" method, I tried booting up a LiveCD on the Windows system and moving the files using the live OS. Under that Ubuntu, the files were readable and writable on the mounted NTFS partition, but when I booted back on Windows, it showed that the file is there but Windows was unable to access it in any fashion: rename, delete or open.) I tried running rename 's/\:/_' * inside the folder, but I got Argument list too long error. Some search revealed that it happens because I have so many files, and then I arrived here. The problem is that I don't know how to alter the command to suit my needs, as I always end up having various errors like Trying find -name '*:*' | xargs rename : _, it gives xargs: unmatched single quote; by default quotes are special to xargs unless you use the -0 option [\n] syntax error at (eval 1) line 1, near ":" [\n] xargs: rename: exited with status 255; aborting Adding the -0 after xargs turns the error message to xargs: argument line too long These files are archive files generated by various PHP scripts. The best solution would be having a chance to rename them before they are moved to Windows, but if there is no way to do it, we might have a way to rename the files while they are moved to Windows. I use samba and proftpd to move the files. Unfortunately, graphical software are out of the question as the server containing the files is what it is, a server, with only command-line interface.

  • Application specific environment variable settings

    - by SuperElectric
    I'm trying to work around a known bug in Ubuntu 9.10, where using the scrollbar in emacs causes text to be highlighted, and the cursor to move. This page here shows that you can fix this by setting an environment variable before launching emacs: $ GDK_NATIVE_WINDOWS=1 emacs So a lazy fix would be to alias "emacs" in my .bashrc: alias emacs="GDK_NATIVE_WINDOWS=1 emacs" This, however, has the drawback of setting this environment variable for all subsequent commands run from that shell. Is there any way to set GDK_NATIVE_WINDOWS=1 for just emacs, whenever I run emacs?

  • Clicking links in pdfs opened with Okular opens Abiword (instead of the default browser)

    - by Marius Hofert
    I work with Xubuntu 12.04 and use Okular (version 0.14.3) to view pdf files. If I click a link in a pdf file (created with pdflatex using the hyperref package), Abiword is opened instead of my default browser google-chrome. How can I change this behavior? The settings in Okular do not seem to provide a solution. (Note that I set google-chrome as the preferred application for web browsing under Settings - Preferred Applications, so that's not the problem).

  • Memory limiting solutions for greedy applications that can crash OS?

    - by Hooked
    I use my computer for scientific programming. It has a healthy 8GB of RAM and 12GB of swap space. Often, as my problems have gotten larger, I exceed all of the available RAM. Rather than crashing (which would be preferred), it seems Ubuntu starts loading everything into swap, including Unity and any open terminals. If I don't catch a run-away program in time, there is nothing I can do but wait - it takes 4-5 minutes to switch to a command prompt eg. Ctrl-Alt-F2 where I can kill the offending process. Since my own stupidity is out of scope of this forum, how can I prevent Ubuntu from crashing via thrashing when I use up all of the available memory from a single offending program? At-home experiment*! Open a terminal, launch python and if you have numpy installed try this: >>> import numpy >>> [numpy.zeros((10**4, 10**4)) for _ in xrange(50)] * Warning: may have adverse effects, monitor the process via iotop or top to kill it in time. If not, I'll see you after your reboot.

  • How can I determine whether a shellscript runs as root or not?

    - by EvilPhoenix
    This is something I've been curious about. I make a lot of small bash scripts (.sh files) to do tasks that I routinely do. Some of those tasks require everything to be ran as superuser. I've been curious: Is it possible to, within the BASH script prior to everything being run, check if the script is being run as superuser, and if not, print a message saying You must be superuser to use this script, then subsequently terminate the script itself. The other side of that is I'd like to have the script run when the user is superuser, and not generate the error. Any ideas on coding (if statements, etc.) on how to execute the aforementioned?

  • Locate a user's bashrc file

    - by Starkers
    Really confused. Upon running cat etc/passwd I have found this: postgres:x:117:126:PostgreSQL administrator,,,:/var/lib/postgresql:/bin/bash meaning I have a postgres user, right? I want to change the bashrc environment file of this user to make commands available to it. /var/lib/postgresql doesn't contain a bashrc file, and /bin/bash doesn't contain it either, so I don't really know what's going on. All I know is a created postgres using the useradd command, so why do I have some weird user with no home directory? So confused :(

  • Shutdown/logoff script in Ubuntu 13.10

    - by TNT
    Which would be the best way to run a script upon GUI logoff, shutdown, hibernate, sleep modes? In 12.04 I think I did this in /etc/lightdm/lightdm.config, but on 13.10, the folder structure changed and when I create this script, The display manager wont even start upon boot. I am looking to implement a simple automatic truecrypt unmount command truecrypt -d but of course this would go for any script.

  • Problem with Ubuntu and UEFI (Problem with any linux OS)

    - by K.T.Sumant
    I have purchased a new Sony Vaio laptop and it is said that the Windows in the recent laptops is installed in the UEFI mode. But all the Linux OS are installed in default in Legacy mode. When I reboot my laptop, Ubuntu is not being detected on boot. Only Windows is detected. To access Ubuntu, whenever I boot the system, I need to: (1) enter the boot menu, (2) change the mode to legacy, and (3) type a bit of scary commands in grub then Ubuntu successfully opens. This is a bit of problem for me. So I wanted to know the solution for this problem. So please kindly look over my problem as soon as possible.

  • virtual box upgrade

    - by Husni
    I did upgrade virtualbox from 4.1 to 4.2 wheneverver I want to load my win xp vdi, it gives me the following error: "Kernel driver not installed (rc=-1908) The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing '/etc/init.d/vboxdrv setup' as root. If it is available in your distribution, you should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary." I ran the suggested step to reinstall the kernel module, and the log file files is as follow: Makefile:181: * Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR= and run Make again. Stop. Makefile:181: * Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR= and run Make again. Stop.

  • Trying to compile from source newest apache with newest openssl

    - by AlexMA
    I need to install apache 2.4.10 using openssl 1.0.1i. I compiled openssl from source with: $ ./config \ --prefix=/opt/openssl-1.0.1i \ --openssldir=/opt/openssl-1.0.1i $ make $ sudo make install and Apache with: ./configure --prefix=/etc/apache2 \ --enable-access_compat=shared \ --enable-actions=shared \ --enable-alias=shared \ --enable-allowmethods=shared \ --enable-auth_basic=shared \ --enable-authn_core=shared \ --enable-authn_file=shared \ --enable-authz_core=shared \ --enable-authz_groupfile=shared \ --enable-authz_host=shared \ --enable-authz_user=shared \ --enable-autoindex=shared \ --enable-dir=shared \ --enable-env=shared \ --enable-headers=shared \ --enable-include=shared \ --enable-log_config=shared \ --enable-mime=shared \ --enable-negotiation=shared \ --enable-proxy=shared \ --enable-proxy_http=shared \ --enable-rewrite=shared \ --enable-setenvif=shared \ --enable-ssl=shared \ --enable-unixd=shared \ --enable-ssl \ --with-ssl=/opt/openssl-1.0.1i \ --enable-ssl-staticlib-deps \ --enable-mods-static=ssl make (would run sudo make install next but I get an error) I'm essentially following the guide here except with newer slightly newer versions. My problem is I get a linker error when I run make for apache: Making all in support make[1]: Entering directory `/home/developer/downloads/httpd-2.4.10/support' make[2]: Entering directory `/home/developer/downloads/httpd-2.4.10/support' /usr/share/apr-1.0/build/libtool --silent --mode=link x86_64-linux-gnu-gcc -std=gnu99 -pthread -L/opt/openssl-1.0.1i/lib -lssl -lcrypto \ -o ab ab.lo /usr/lib/x86_64-linux-gnu/libaprutil-1.la /usr/lib/x86_64-linux-gnu/libapr-1.la -lm /usr/bin/ld: /opt/openssl-1.0.1i/lib/libcrypto.a(dso_dlfcn.o): undefined reference to symbol 'dlclose@@GLIBC_2.2.5' I tried the answer here, but no luck. I would prefer to just use aptitude, but unfortunately the versions I need aren't available yet. If anyone knows how to fix the linker problem (or what I think is a linker problem), or knows of a better way to tell apache to use a newer openssl, it would be greatly appreciated; I've got apache 1.0.1i working otherwise.

  • What does /dev/null mean in the shell?

    - by rishiag
    I've started learning bash scripting by using this guide: http://www.tldp.org/LDP/abs/abs-guide.pdf However I got stuck at the first script: cd /var/log cat /dev/null > messages cat /dev/null > wtmp echo "Log files cleaned up." What do lines 2 and 3 do in Ubuntu (I understand cat)? Is it only for other Linux distributions? After running this script as root, the output I get is Log files cleaned up. But /var/log still contains all the files.

  • Ubuntu 13.10 not playing DVD videos

    - by John Hill
    I installed Ubuntu Gnome 13.10 on my computer yesterday, and everything seems to be working fine so far, except that it isn't reading video or audio CD's and DVD's. At first, I inserted a DVD video, and it played normally for maybe 30-45 seconds before coming up with a "internal read error" or something like that. I was using the Totem player when the problem occurred, so I tried installing the VLC media player. It wouldn't read the disc at all, so I uninstalled the player. Now, the Totem player won't even begin playing the DVD. The player sometimes doesn't even open up when I insert the DVD, and other times it will but says it can't read it. I've tried several different DVD's and CD's with similar results. The computer is recognizing the optical drive, because when I open "Files", it shows the drive and the disc, but can't play it. Previously, I ran Ubuntu 13.04 with the Gnome desktop installed from the software center, and I had no issues. Any help is appreciated!

  • Modal popup showing on the wrong monitor

    - by Chase Seibert
    On Ubuntu 11.10, I'm seeing modals from many applications show up on a different monitor from their parent application. In this example, Firefox, the application on the right most monitor, has popped up a modal dialog in the center monitor. You'll notice that it is not just on the wrong monitor, it's also positioned horizntally against the left edge of that monitor. Vertically, it's centered. This happens for at least Firefox, Eclipse and gedit modals. It seems like it's all applications. It doesn't matter which monitor the parent application is on, the modals are always on the left edge of the center monitor.

  • Alsa doesn't work in vlc

    - by freebird
    Alsa Audio Output works fine from terminal, e.g. aplay /usr/share/sounds/alsa/Noise.wav. But I got to change from default to Alsa Audio Output in vlc. I found it in Tools Perfernces Audio Outputs. The issue is that when I change it to Alsa, I Loose all sound. When I leave the default I get an annoying Audio delay of about 200ms or 500ms. From what I have found you have to use Alsa Audio Outpu to fix that issue. Updated 6-26-2011 10:28pm To fix the Alsa Audio Output: sudo add-apt-repository ppa:ferramroberto/vlc sudo apt-get update sudo apt-get install vlc mozilla-plugin-vlc then, opened Update Manager, there were 2 updates for vlc there, I installed them and rebooted. Now alsa works fine and audio is in sync with video.
