holsteinKiteHawk: ? kubuntu has the same kernel01:11
holsteinshould have sound.. make sure its not just you getting used to the KDE environment01:11
KiteHawkI think it actually was my graphics card01:15
holsteinyup.. the driver*01:16
KiteHawki thought i was using the onboard but i saw it was a funky card so i upgraded and loaded kubuntu and mixxx jumped right up01:16
KiteHawkmy bad01:16
KiteHawkbut yes now when i click on sound settings nothing happens01:17
holsteinsure.. but the kernel is the same01:17
KiteHawkat top of screen where sound volume control is01:17
holsteinopen a terminal, and run01:17
holsteinaplay -l01:17
holsteinyou'll see what devices are listed, if any01:17
holsteinalso, open in the terminal alsamixer, and trust none of the lables01:18
holsteinlabels*01:18
KiteHawkok its remote and xfce environment has no vnc or am i mistaken about that?01:18
holsteinKiteHawk: ?01:18
KiteHawkalsamixer i did that but i will up the volumes to verify01:19
holsteinXFCE is alternatice to KDE01:19
holsteinvnc is a way to share a desktop. you can do that with any environment01:19
holsteini use vino and vinagre usually from XFCE01:19
KiteHawkthe machine is another machine than the one im on so i usually operate it through vnc or ssh but neither are setup yet01:19
holsteinsure... use whatever software you want01:20
KiteHawkah c i didnt know the program vino allows sharing desktop'01:20
holsteinVNC, tight VNC.. vino... whatever01:20
holsteinteamviewer01:20
KiteHawkk01:20
holsteinalso, use those with whatever desktop you want01:20
holsteinthough, typically, we dont use vino with KDE01:21
KiteHawkubuntu 12.04 has it in the menu to start01:21
holsteinand whatever the native one to KDE... you might not want to use that in gnome or XFCE01:21
KiteHawkso xfce is preferred because its faster?01:21
holsteinKiteHawk: xfce is preferred only if you prefer it01:22
KiteHawknot sure exactly how to choose01:22
holsteini personally dont like KDE01:22
holsteinand im not useing XFCE right now either, though i like it better, and support it01:22
KiteHawkok for audio production purposes01:22
holsteinKiteHawk: for whatever01:22
holsteindoesnt matter01:22
holsteinif you are remoting into an audio server occasionally, you dont need much of a desktop01:22
holsteinmaybe LXDE would be enough01:22
KiteHawkhmmm so why the variety just for variety sake?01:23
holsteinKiteHawk: they are different01:23
holsteinis XFCE faster than KDE? by default id say sure01:23
holsteinbut, KDE is different, and answers a different user base01:23
holsteincan you have KDE and run ubuntustudio software? sure01:24
KiteHawkubuntu studio for example is a collection of media for install so it would be considered media centric?01:24
holsteinits all open, so the answer is always "yes".. its just how much of a pain01:24
holsteinKiteHawk: ubuntustudio is us01:24
holsteinits you and me01:24
holsteinits a pre-set up version of ubuntu with customizations01:25
holsteinwe have metapackages... groups of software for tasks01:25
holsteinyou dont need ubuntustudio or any of the metapackages01:25
KiteHawkyes i understand the flexability is there but how is the protocol developed?01:25
KiteHawkwhat is the strenght of ubuntu studio?01:26
holsteinits an out of the box solution01:26
holsteinfor audio and other things...01:26
KiteHawkstrength(s)01:26
holsteinif you want to have ubuntustudio, you install it, and have it01:26
KiteHawkyeah01:26
holsteinits really something that no other operating system has01:26
holsteinits like, if you bought OSX with protools and all the plugins preinstalled01:26
holsteinwith a differnt wallpaper01:26
holsteinand icons01:26
holsteinthat would be "appleOSX studio"01:27
holsteinthat cant exist though... but we can do whatever01:27
KiteHawki guess i get confused when so many things get loaded and it seams like one ubuntu is different from another01:27
holsteinKiteHawk: they are all different, sure.. but the same base01:27
holsteinubuntustudio *is* ubuntu... *is* kubuntu01:27
holsteinbut, kubuntu is quite different01:28
holsteinxubuntu and ubuntustudio look a lot alike now01:28
holsteinlike ubuntustudio and ubuntu did01:28
KiteHawkcorrect and keeping track is where i need know01:28
holsteinbut ehy are all the same01:28
holsteinKiteHawk: nah.. just try em live, and enjoy01:28
holsteinmost distros have live CD's01:28
holsteinand all of them have the linux kernel in some form of other01:29
KiteHawkyes i have been since version 6 but i'd like to be able to get to the task easily so as to appreciate ubuntu that much more01:29
KiteHawki luv ubuntu:)01:29
KiteHawk8)01:30
holsteinversion 6?01:30
holstein6.04?01:30
KiteHawkthanks also for your support01:30
holsteinsure.. anytime01:30
holsteinor was it 6.10?01:30
KiteHawkyes i started with a mac ppc ubuntu 6.0401:30
holsteini loaded that up for history's sake01:31
holsteinppc is a pain01:31
KiteHawkit was just before 8.04 came out01:31
KiteHawkit sucks i had to let them all go01:31
holsteinppc?.. i was glad to drop them off and the recyclers :)01:31
KiteHawkno more support for the most part and they were quality servers01:32
holsteini have a couple still i run headless01:32
KiteHawkrun forever01:32
KiteHawkyeah01:32
KiteHawkbus speed is horrible01:32
holsteinrunning a desktop on them is a pain01:32
holsteinok... gtg... enjoy!01:32
holsteinim going on vaction and might be on spotty network for a while01:32
KiteHawkcool have a great vacation  :D01:33
KiteHawkheadless i didn't catch that what is?01:34
acmeincwhat is the latest kernel version on U-S 12.04?02:47
acmeinci started using a custom kernel and realized i haven't been getting updates.   wanna check if mine is actually the latest02:48
acmeinchehe, timmy asks me every week to go to charlie murdochs now02:48
acmeincwrong message, lolz02:50
game2acmeinc: Yes, no kernel updates on u-s.  But that is irrelevant if you are using a "custom kernel" surely?03:04
acmeinci reverted back, but thx :)03:05
MishThere seems to be some problem in rendering text in Ubuntu studio. Black text doesn't appear totally black but appears to have purple and green colourations like in this screenshot.07:54

Unit193hypnocat: Hello, nice nick.16:20
hypnocathi16:20
hypnocatthanks :)16:20
hypnocati need a little help with ubuntu studio16:21
hypnocati'd like to install a synth app called "din", for which ubuntu packages exist here:  https://launchpad.net/~dinisnoise/+archive/din/+packages16:21
hypnocathow would i do that?16:21
holsteinhypnocat: i used the .deb16:21
hypnocathow do i use the deb?16:21
hypnocati'm new to ubuntu16:21
holsteinhttps://launchpad.net/~jagernot/+archive/din-is-noise16:22
holsteinthough, remember the information at the site being pretty easy16:22
hypnocatwhich of those debs do i download?16:22
hypnocatand how do i install them?16:22
holsteinyou can literally click them and run them, though i would read the site16:22
hypnocatah16:23
holsteinhttp://dinisnoise.org/download/16:23
holsteinhttps://launchpad.net/~dinisnoise/+archive/din/+packages is where the site sends you16:23
hypnocatalso, which ubuntu version does ubuntu-studio correspond to?  maverick?  lucid? karmic?16:24
holsteinhttps://launchpad.net/~dinisnoise/+archive/din/+files/din_3.5~precise~ppa1_i386.deb for example, if you are on 23bit 12.0416:24
holsteinhypnocat: depends on which version you have16:24
holstein12.04 is precise...16:24
holsteinlucis is 10.04...16:24
hypnocati'm definitely using 12.0416:24
hypnocati forget which version i burnt on this dvd, though.. 32 or 6416:25
holsteinhypnocat: in a terminal, run "uname -a"16:25
hypnocati'm on a 64 bit system, and "uname -a" reports:  Linux ubuntu-studio 3.2.0-23-lowlatency #31-Ubuntu SMP PREEMPT Wed Apr 11 02:24:03 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux16:25

hypnocatthanks16:25
holsteindin uses 3d acceleration, so when it wont start, you can start troubleshooting there16:26
holsteinif it wont start*.. i should be more optimistic :)16:26
hypnocatheh16:27
hypnocatit started16:28
holsteincool! enjoy!16:28
hypnocatnow i have to remember how to use it..16:28
hypnocattime to watch the tutorial videos again..16:29
hypnocatthanks for your help!16:29
holsteinsure... anytime16:29
vaevfew more questions about ubuntu studio pulse-jack solution so I understand it right (I'm doing research on the subject, so this is not strictly US support related)16:59
vaevfirstly, are you using the mixed jackd/jackdbus approach or plain jackdbus?16:59
vaev(as per http://trac.jackaudio.org/wiki/JackDbusPackaging )16:59
len-dtjackdbus17:02
len-dtThe bridging will not work without it.17:02
vaevsecondly, have you attempted using jack server as a boot time launched daemon? or simply letting users manually start it / programs autolaunch it, resulting in dynamic autonegotiation between pulse and jack if jack is running? and when it's stopped pulse would reacquire the alsa devices17:02
len-dtHowever the user is able to choose not touse dbus.17:03
vaevlen-dt: actually it will if you statically configure module-jack-sink in pulse to be the only option without alsa fallback (letting pulseaudio launch jackd or jackdbus if available)17:03
vaevokay17:04
len-dtOk I did not know that.17:04
len-dtWe only have so many people for testing... So we have not done the amount of testing you have even.17:05
vaevI can post my findings on the subject to your mailing list.. I'm attempting to compose a guide as generic as possible regarding this matter17:06
len-dtIf we were doing an Audio only distro it would just be jack.17:06
len-dtWe are trying to get the "normal" desktop experience to work as well.17:06
vaevI'm trying to find a decent solution with minimal user interaction with the daemons needed for complete desktop and proaudio usage17:07
len-dtI think things will change again as Firewire makes its way into ALSA.17:07
len-dtI also think there are new things coming in both pulse and jackd that will change things too.17:08
len-dtThe one thing I have noticed is that turning off PA-jack bridging seems to be jsut as effective as turning off pulse.17:09
len-dtThis is easy to do on the fly.17:09
vaevI'm trying to keep an eye on them both. going to post to jack-devel soonish if they could evaluate my findings and suggest where to start repairing certain issues that have arisen17:10
vaevjust hoping I don't fire up a powder keg of alsa-pulse-jack politics :)17:11
len-dtHowever, If I was doing "pro" audio. I personally would have the audio processing computer(s) with just jackd and no external net access.17:11
len-dtI am not suggesting it has to be that way, just my feeling17:12
vaevyep. in those use cases that is sensible17:12
len-dtI would want my audio computer to be as close to a one use box as I could.17:12
vaevsame here. I already have a perfectly working solution for my personal use case, I'm just trying to generalize it so others can benefit from it too17:13
len-dtThere are a lot of other things I would remove as well... including swap and most services.17:13
len-dtThe fun of developing a distro :-)17:13
* len-dt is saying all this while watching youtube on his audio computer...17:14
ailovaev: len-dt: I believe the jackd2 is mixed jackd and mixbus17:16
ailoYou can either run jackd or jackdbus17:17
len-dtYes, it can be run either way. But I am not sure pulse as we have it configured will bridge if jackd is run with out dbus.17:18
ailopulse will only bridge to jackdbus, not jackd17:18
ailoBut the jackd2 package is compiled with mixed jackd2 and jackdbus17:18
ailoSo, both are available17:19
vaevailo: pulse will bridge to jack in both cases, but not automatically if not jackdbus17:19
len-dtYa there are 3 modules involved, one that watches dbus for jack and then loads the sink/source modules as needed.17:21
vaevin case of only jackd it will remain completely oblivious as to it existing but it can be defaulted to load jack modules only, in which case it will start jack server through jackd or jackdbus if available17:21
vaevif it is not running already17:21
ailoAnother problem with jack is audio card selection17:22
len-dtailo, in muticard cases so does pulse.17:23
len-dts/muti.multi17:24
ailoThere's no good gui control for making simple audio card selections17:24
vaevyep. that's another thing I'm going to look into if I choose to go with the static pulse config..to try to automate the usage of alsa_in and alsa_out (from jack package) to use additional cards17:24
vaevfor desktop solutions it might also be enough to let jack reserve one card, and let pulseaudio sink to it..then let pulseaudio load the remaining cards through alsa directly17:25
vaevbut that eliminates the possibility of routing those cards through jack17:25
vaevbut that's something I have to discuss with jack-devel on how to approach best17:26
len-dtThe more I look at multi-track or multi-card uses, the more I am starting to feel, user has to have some understanding of their own system. Even (especially) windows or osx are not immune to this problem17:26
ailoIf jack is to be default, I'd like pulse not to auto-grab any cards. Just wait to connect to jack17:27
vaevailo: that's what I've done17:27
len-dtvaev, Have you done any testing with pulse-jack bridging and how a second card pulse is connected to effects the card jack is connected to?17:28
len-dtI have had problems this way.17:28
ailolen-dt: Was pulse using both the jack sinks, or was something also using the other card simultaniously?17:30
ailoI mean, did you also have pulse sink to the other card17:30
vaevI did some preliminary tests closely related. jack will remain completely oblivious of any cards that pulse grabs directly. I tested with letting jack take the hw:0 in my system and let pulse handle hw:1 (ati hdmi) and hw:3 (usb headset) through alsa17:30
len-dtvaev, That is not true.17:31
vaevoh?17:31
len-dtThey can both run, but the settings in jack will not be able to be any better than the card connected to pulse.17:31
vaevI base what I said on not encountering any problems letting pulse sink to jack and the hw:3 simultaneously17:31
ailolen-dt: You mean, when using the pulse bridge. This was not a case with the bridge, from what I read17:32
len-dtMy internal card on my netbook can get latency to -p128 and it has an issue with the wireless.17:32
len-dtAn external card that with pulse not seeing the internal card can get -p64 and no wireless issues has the same limits when pulse can see the internal card.17:33
len-dtThat is if pulse has the internal card turned on, jack can now only go to -p128 on my external card17:34
len-dtgoing to pavucontrol and turning the internal cards profile to off, lets me use my external card to it's full potential.17:35
len-dtWith bridging turned of this is not a problem.17:36
vaevoh now I see what you mean17:36
len-dtbridgin requires pa and jack to sync17:36
vaevyes, it could have a performance impact17:36
vaevsomething I haven't encountered or measured at this point17:37
len-dtMy internal sound card happens to be pretty bad ;-)17:37
len-dtWhile my netbook is not a great audio platform, with 1G ram and yucky (slow) hardware, it can make a surprisingly good remote recording platform or even guitar effect with an external USB audio IF17:42
len-dtI suppose pa-jack briding _could_ use resampling to get around this problem... but pa-jack bridging already uses twice the cpu time as jackd does. I'm not sure it would be worth it.17:46
len-dt(twice the cpu at -p 128 on my machine, worse at -p 64)17:47
vaevI'll consider this in respect of the static sinking approach17:48
vaevthans for pointing it out :)17:48
len-dtNo problem17:49
