• How do I change the volume control icon?

  - by Richard Oren Pincook

  I recently switched to gnome 3 (love it!), but the default icon theme was a little dreary and gray, so I switched that back to ubuntu-mono-dark. But now whenever I change my volume, I get this ugly pixelated icon show up. The forum says I don't have enough reputation to post an screenshot, but it's pixelated and ugly with these fuzzy straight blue lines that turn on as the volume goes up. I found identical images in the Humanity and Humanity-Dark icon themes (one example: /usr/share/icons/Humanity/status/24/audio-volume-high.png). I tinkered with the images by changing their names, temporarily deleting them, etc. But it had no effect on the ugly icon. What file is responsible for violating the beauty of my desktop?! Once I find it, I can replace it.

  - by Gorog Imre

  I have a Dell 5720 laptop with ubuntu 11.10. I can't connect to my Samsung LCD TV (over Marantz nr 1601 AV). Audio is ok but the pictures are displayed in two colours: green and lila ! Please send me a massage how can I fix this problem ! Thanks a lot. I am very confused because I do not do anything however it comes(seldom) to the right colouring but only for a while(5minutes) and returns to the green-lila picture again when I do something else for example surfing with firefox or starting other programs ! The settings : resolutions of laptopscreenplay and TV are the same and I did not change the colour profile as well . My laptop screen is HD+ truebright (1600x900) and my TV SAmsung 1280x720 I have no idea what to do my HDMI connection to make right with the colours! How can I fix this situation to gain a stable colouring ?

• USB sound device not recognized

  - by David E. Anderson

  I have a USB sound device that used to work back when I ran other versions of Ubuntu. Now I can only partially see the device. I have tried many things I saw in Google searches, but none solve my problem. cat /proc/asound/cards sees the device as card 0 aplay -l shows C-Media USB Audio as card 0 alsamixer sees the device asoundconf list does not show the device sound preferences shows no hardware asoundconf-gtk set the device to pulseaudio, but fails with python errors ending in ValueError: too many values to unpack in the function set_default_card. I think this is the cause of my problem. The device is a Sony virtual phones wireless headphone amplifier.

• Video Did Not Kill the Podcast Star

  Who says video killed the podcast star? We're seeing more favorites out there than ever before. For example, the OTN team is proud to be supporters of the Java Spotlight Podcasts, straight from the official Java Evangelist Team at Oracle (lots of great insider info); the OurSQL: The MySQL Database Podcasts, produced by MySQL maven (and Oracle ACE Director) Sheeri Cabral; and The GlassFish Podcast, always a reliable source. And we'd add The Java Posse and The Basement Coders to our personal playlist. And although we're on a video kick ourselves at the moment, you can still get the audio of our TechCast Live shows, if you think we have "faces for radio."

• How to close lid without triggering standby one time only

  - by Ian Mackinnon

  Related: How can I tell Ubuntu to do nothing when I close my laptop lid? I have my laptop set to activate standby when I close the lid. I want to keep this as the default for both battery and AC power. But occasionally I want to close the lid without triggering standby (eg. while just listening to audio). Is there someway I can tell Ubuntu, "I'm going to close the lid now. Don't stand by this time", without altering the defaults (because I almost always forget to change them back).

• MPD to play music to single channel of my multi-channel card?

  - by hany tawfik

  I installed an Ubuntu 12-04 LTS server for a special background music application of mine, where I am using the server with an Asus Xonar DS sound card. The installation is successful, the MPD is working, the sound card is working with Alsa and its libraries installed accept for Alsa-oss. Alsamixer is working fine with left/right sides of each channel volume control through Q/Z letters shortcut when alsamixer is open in terminal . using the command " speaker-test -Dplug:surround71 -c8 -l1 -twav " I can hear every voice message coming out from the card at the right connector, so "front right/ front left" voice message are coming from first output in the card back, while the other outputs are silent..so on. The problem is that MPD is playing on all outputs simultaneously the same audio. I have been trying various configurations for the last 12 days with out any success, including trying to put mappings in the /etc/asound.conf Can any body help me achieve the above, or direct me to the right configuration of MPD or asound.conf

• How can I force the (re)discovery of PulseAudio network sound devices?

  - by Christian

  I'm using the PulseAudio feature of network sound devices (not Multicast/RTP) to play sound from my netbook on the audio equipment connected to the HTPC when at home. This creates a virtual sound device that I can then use instead of the physical built-in one. Most of the time this works just fine. Sometimes however, the virtual sound device just doesn't appear. Disconnecting from and reconnecting to the network helps sometimes but not always and it's annoying and potentially bad for existing TCP connections. So my question basically is: Is there some way to tell PulseAudio "Hey, just look again if you really can't find a network sound device."? Edit: Unloading and reloading the module-zeroconf-discover with pacmd does not help either and it doesn't appear to be an avahi problem per se since avahi-browse -t --all | grep PulseAudio shows lots of right-looking stuff, even when the devices aren't listed in pavucontrol or pacmd list-sinks. Edit 2: I'm using Ubuntu 12.04 on both boxes for all the difference it might make.

• Atheros AR2413 wireless not working after shutdown

  - by Chandrasekhar

  I am using a Ubuntu 11.04 on an Acer aspire 3680 laptop and my wifi is not working. I followed the below commands to install the madwifi driver: sudo su apt-get install subversion cd /usr/src svn checkout http://madwifi-project.org/svn/madwifi/trunk madwifi tar cfvz madwifi.tgz cd madwifi make && make install echo "blacklist ath5k" /etc/modprobe.d/blacklist.conf echo "ath_pci" /etc/modules modprobe ath_pci sudo reboot After installation I am facing the same problem. My wifi wont work after I shutdown. Infact it didn't work after suspend but I rectified that problem by the following commands: Command 1: sudo rmmod -f ath_pci sudo rfkill unblock all sudo modprobe ath_pci along with the command SUSPEND_MODULES=ath_pci added to the /etc/pm/config.d/madwifi directory. So if I suspend and then on my laptop the wifi loads well and doesn't create a problem. But if I shutdown my laptop the wifi never loads again and eachtime I have to run a Ubuntu 9.04 live CD to load it. I did try adding the Command 1 to the /etc/rc.local directory but still it doesn't work. So my question is: What should I do in order to make my wireless work without having to run a live CD of ubuntu 9.04 everytime after shutdown? Thanks.

• How can I determine which GPU card is running at PCI Express 2.0 x16 & which is using x8?

  - by M. Tibbits

  Is there a way to determine the speed of the PCI Express connection to a specific card? I have three cards plugged in: two Nvidia GTX 480's (one at x16 & and one at x8) one Nvidia GTX 460 running at x8 Is there some way, either by a function call in C or an option to lspci that I can determine the bus speed of the graphics cards? When I only use one of the cards for my CUDA program, I'd like to use the one which is running at x16. Thanks! Note: lspci -vvv dumps out For the two GTX 480s.

• Alsa version numbers not consistent

  - by user69245

  I've recently moved from 10.04 to 12.04 and have problems with crackles on audio when the screen changes (especially obvious in a Skype conversation with video). !!Kernel Information !!------------------ Kernel release: 3.2.0-26-generic-pae Operating System: GNU/Linux Architecture: i686 Processor: i686 SMP Enabled: Yes !!ALSA Version !!------------ Driver version: 1.0.24 Library version: 1.0.25 Utilities version: 1.0.25 Running through the SoundTroubleShooting procedures I got the above details at Step 3. Is the mismatch between the Driver version (1.0.24) and the Library and Utilities versions (1.0.25) the cause of my problem, or should I be looking elsewhere? In answers to the question "Will ALSA 1.0.25 version have time to enter 12.04?" I read that 1.0.25 would be part of the new kernel, but my kernel version appears to be newer than the original release.

• Skype no sound on Kubuntu 13.10

  - by Michael Aquilina

  I just performed a fresh install of Kubuntu 13.10 on my machine. Everything is working great except for Skype. I cannot get any form of audio playback in Skype. In the sound settings panel I get a bunch of different sound sources, none of which work! At the moment I have set it to "sysdefault (unknown)" I installed it using the deb package found on the official website. My phonon backend is using phonon-gstreamer. When running skype from the terminal I get the following error messages: ALSA lib control.c:953:(snd_ctl_open_noupdate) Invalid CTL plughw:CARD=PCH ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave Is this a known problem or has anyone experienced the problem and managed to solve it?

• Advice on developing a social network [on hold]

  - by Siraj Mansour

  I am doing research on assembling a team, using the right tools, and the cost to develop a highly responsive social network that is capable of dealing with a lot of users. Similar to the Facebook concept but using the basics package for now. Profile, friends, posts, updates, media upload/download, streaming, chat and Inbox messaging are all in the package. We certainly do not expect it to be as popular as Facebook or handle the same number of users and requests, but in its own game it has to be a monster, and expandable for later on. Neglecting the hosting, and servers part, i am looking for technical advise and opinions, on what kind of team i need ? how many developers ? their expertise ? What are the right tools ? languages ? frameworks ? environments ? Any random ideas about the infrastructure ? Quick thoughts on the development process ? Please use references, if you have any to support your ideas. Development cost mere estimation ? NEGLECTING THE COST OF SERVERS I know my question is too broad but my knowledge is very limited and i need detailed help, for any help you can offer i thank you in advance.

• Live programming help

  - by frazras

  This idea has been floating around my head for a few years. I started some work on it but I just want to know if it is feasible, sensible, or if there is something else like it out there. Dont want to know I was wasting time on a solved issue. Whenever I have a programming issue, this is my sequence: Google it!: That usually brings up a lot of things: blogs, forums, stackoverflow, stackexchange, and even the official docs of the language/framework/cms. Ask on IRC: I format my question and try to get people on IRC to help me. Make a post: I create a post on forums/stackoverflow/stackexchange or shout on twitter with hashtags. Now a lot of the time I am in the middle of a project with a deadline. So I want answers NOW!!! Sometimes just 5-15 minutes worth of attention. Usually by the time I am failing at getting answers at #2, I am imagining how many people are ONLINE NOW with the skill and my exact answer but playing video games, watching youtube or idling online. However, if they were motivated, they would invest the 15 mintes helping me, that would make a world of a difference. I am even in positions where I would PAY for that 15 minutes of instant help. If your rate is as much as $100/hour (relatively good programmer) that is $25 that might save me 3 hours. This help would be live, text chat/skype/phone/screenshare. Should I continue developing this idea or is there a better alternative out there? Or is this even an unfeasible idea?

• What are the requirements to test a website using jquery.get() ? [migrated]

  - by Frankie

  I am working on a simple website. It has to search quite a few text files in different sub-folders. The rest of the page uses jquery, so I would like to use it for this also. The function I am looking at is .get() for downloading the files. So my main question is, can I test this on my local computer (Ubuntu Linux) or do I have to have it uploaded to a server? Also, if there's a better way to go about this, that would be nice to know. However, I'm more worried about getting it working. Thanks, Frankie PS: Heres the JS/jQuery code for downloading the files to an array. g_lists = new Array(); $(":checkbox").each(function(i){ if ($(this).attr("name") != "0") { var path = "../" + $(this).attr("name") + ".txt"; $("#bot").append("<br />" + path); // debug $.get(path, function(data){ g_lists[i] = data; $("#bot").html(data); }); } else { g_lists[i] = ""; } }); Edit: Just a note about the path variable. I think it's correct, but I'm not 100% sure. I'm new to web development. Here's some examples it produces and the directory tree of the site. Maybe it will help, can't hurt. . +-- include ¦   +-- jquery.js ¦   +-- load.js +-- index.xhtml +-- style.css +-- txt    +-- Scripting_Tools    +-- Editors.txt    +-- Other.txt Examples of path: ../txt/Scripting_Tools/Editors.txt ../txt/Scripting_Tools/Other.txt Well I'm a new user, so I can't "answer" my own question, so I'll just post it here: After asking for help on a IRC chat channel specific to jQuery, I was told I could use this on a local host. To do this I installed Apache web server, and copied my site into it's directory. More information on setting it up can be found here: http://www.howtoforge.com/ubuntu_debian_lamp_server Then to run the site I navigated my browser to "localhost" and everything works.

• Why does running this program on 11.10 give a 'GLIBC_2.15 not found' error?

  - by RafLance

  I am trying to install Absinthe 2.0.4 on Ubuntu 11.10 on a netbook. When I try to run the install file, this keeps on happening: rafael@RafLaptop:~/Desktop/absinthe-linux-2.0.4$ ./absinthe.x86 ./absinthe.x86: /lib/i386-linux-gnu/libc.so.6: version `GLIBC_2.15' not found (required by ./absinthe.x86) Do I need to upgrade GLIBC? If so, how do I do that? Since I'm on a netbook I can't use a LiveCD so I wanted to know if there was a way I could fix this issue without reinstalling my whole OS. Any explanations about what GLIBC is exactly would be great too since this is a learning experience for me. I know that GLIBC is a part of libc.so.6 and so I tried to run sudo apt-get install libc.so.6 but was told that it was up to date. But GLIBC isn't? I hope this articulates my problem well, if there are any pieces of missing info or questions to clarity my question, please let me know! ~-~ EDIT/UPDATE: So after some help on the AskUbuntu chat room from user izx, I have gathered the following information/understanding: -I need to run this program with Ubuntu 12.04 or recompile it from source -Upgrading libc on Oneiric to 2.15 while possible, is not an easy task and is not officially supported.

• How do I make my volume indicator operate in decibels instead of percentage?

  - by ethana2

  When I want to adjust the volume of anything I'm doing, I find that using the volume controls built into Ubuntu is little but confusion. When the volume is around 100%, dropping it several increments has almost no effect on apparent volume, but when it's around 0%, the effect of one click of my mouse wheel is probably a good 3 decibels. I have observed this behavior on tens of different UC's, since I convert about one Ubuntu user a month (NE team contact). This has proven so frustrating to me that I tend to use the volume knob on my guitar amp ( mono audio :| ) instead of the volume indicator. What can I do to make my volume indicator behave properly until this is fixed? I want each volume increment to be one half or one third decibel. Is there a different piece of software I should use for system volume configuration perhaps?
