[00:03] <virtu> hi
[03:46] <ajwill> hi all, I was wondering, is it possible to go from normal ubuntu 10.10 to ubuntu studio 10.4 or 10.10 without formatting and re-installing all programs and files and such?
[03:48] <holstein> ajwill: i dont know of a way to go back from 10.10 to 10.04
[03:48] <holstein> sudo undo ;0
[03:48] <holstein> ajwill: ubuntustudio = ubuntu
[03:48] <holstein> SO you can always just add whatever software you want to your current ubuntu install
[03:49] <holstein> i would suggest search where ever you install packages
[03:49] <holstein> synaptic, software center, apt-cache search...
[03:49] <ajwill> but one problem I'm having is Jack seems to refuse to work on my comp... I tried for like 4 hours today to get it to work and still got nothing
[03:49] <holstein> search for ubuntustudio
[03:49] <holstein> and read about the meta packages
[03:49] <holstein> ajwill: what is the error?
[03:49] <holstein> ajwill: actually
[03:49] <holstein> what hardware are we talking about
[03:50] <holstein> an internal sound card?
[03:50] <ajwill> yes, I have no external sound anything besides the fact that I want to record my GT-10 plugged via usb into my computer
[03:50] <holstein> OK
[03:50] <holstein> open a terminal
[03:50] <holstein> and typr
[03:51] <holstein> type*
[03:51] <holstein> sudo qjackctl
[03:51] <holstein> then
[03:51] <holstein> open 'setup'
[03:51] <holstein> and lets look at the settings
[03:51] <ajwill> can I just open qjackctl normally in user?
[03:51] <holstein> not yet
[03:51] <ajwill> okay
[03:51] <holstein> you can if you want
[03:51] <holstein> this will test for permissions errors though
[03:52] <holstein> then we will hopefully learn why it aint 'giving up the funk' ;)
[03:52] <ajwill> okay
[03:52] <ajwill> I have it open and I'm in the settings window
[03:52] <holstein> in the center
[03:52] <holstein> frames/period
[03:53] <holstein> set that to 512
[03:53] <ajwill> done
[03:53] <holstein> sample rate
[03:53] <holstein> 44100
[03:53] <ajwill> done
[03:53] <holstein> periods/buffer 3
[03:53] <ajwill> done
[03:53] <holstein> above that
[03:53] <holstein> 'driver'
[03:53] <holstein> what is that set to?
[03:53] <ajwill> alsa
[03:53] <holstein> alsa?
[03:53] <holstein> cool
[03:53] <ajwill> yes
[03:53] <holstein> say OK
[03:54] <holstein> and try hitting 'start'
[03:54] <ajwill> okay done
[03:54] <holstein> back out on the main panel
[03:55] <holstein> whats the good news?
[03:55] <ajwill> its working, but the latency is higher than most suggest having it
[03:55] <holstein> ajwill: COOL
[03:55] <holstein> progress :)
[03:55] <holstein> OK
[03:55] <holstein> stop it
[03:55] <holstein> and close it
[03:55] <holstein> and lets run
[03:55] <holstein> in a terminal
[03:56] <ajwill> okay
[03:56] <ajwill> terminal open..
[03:56] <holstein> sudo adduser ajwill audio
[03:56] <holstein> ASSUMING
[03:56] <holstein> the username on your box is ajwill
[03:56] <holstein> i would run...
[03:56] <ajwill> okay
[03:56] <holstein> sudo adduser holstein audio
[03:56] <holstein> this adds your user to the audio group
[03:56] <ajwill> done
[03:57] <holstein> OK
[03:57] <holstein> you might need to log out and back in for that to take effect
[03:57] <holstein> i forget :/
[03:57] <holstein> BUT try JACK
[03:57] <holstein> as normal user
[03:57] <holstein> if it doesnt start
[03:57] <ajwill> I did it earlier today from googling stuff andthat's already done
[03:57] <holstein> log out and back in
[03:57] <holstein> then try
[03:57] <holstein> and i that doesnt work... let me know
[03:58] <holstein> ajwill: so you were already in the audio group?
[03:58] <ajwill> yes
[03:58] <ajwill> its working
[03:58] <holstein> cool
[03:59] <holstein> SO
[03:59] <holstein> when jack is stopped
[03:59] <holstein> you can tweak the settings
[03:59] <holstein> the ones in the center are the ones we mess with
[03:59] <holstein> the...
[03:59] <holstein> frames/period
[03:59] <holstein> and periods/buffer
[03:59] <holstein> with an internal card
[03:59] <holstein> i feel like 20ms stable is pretty good
[04:00] <holstein> you might be able to push to under 10ms
[04:00] <holstein> ajwill: IF your not doing any realtime effects processing
[04:00] <holstein> OR running softsynths live
[04:00] <holstein> you really dont need lower latency
[04:00] <holstein> depends on what your needs are
[04:00] <ajwill> the current latency is 34.8 and just a note, whenever I start it, it says there's an error, but then it starts normally
[04:01] <holstein> ajwill: probably an older error in the window
[04:01] <holstein> its kind of a running log
[04:01] <holstein> sort of
[04:01] <ajwill> and I may want to eventually use synths and such to write my own other stuff but for now its fine
[04:01] <ajwill> yes but every time I start it
[04:01] <ajwill> it pops up again
[04:01] <holstein> yeah
[04:01] <ajwill> over in the tray icon
[04:01] <holstein> OH
[04:01] <holstein> an xrun?
[04:01] <ajwill> saying that it's not working
[04:01] <ajwill> but then it works
[04:01] <holstein> when you start?
[04:01] <ajwill> nope
[04:01] <holstein> hmmm
[04:02] <holstein> in the 'window'
[04:02] <holstein> 'messages' window
[04:02] <holstein> ?
[04:02] <holstein> try clicking on 'messages'
[04:02] <ajwill> it pops up saying that it could not connect to jack server as client in messages
[04:02] <ajwill> and then goes through a bunch of other stuff
[04:02] <ajwill> then works...
[04:02] <holstein> and see if that keeps the messages from popping up
[04:03] <holstein> when i click on 'messages' right now
[04:03] <holstein> i get a window that opens
[04:03] <holstein> with a log
[04:03] <holstein> from whenever i was running JACK on here last
[04:03] <holstein> ajwill: xruns are bad
[04:03] <holstein> other than that
[04:03] <holstein> i wouldnt worry
[04:03] <holstein> you can try different kernels if you want
[04:03] <holstein> -lowlatency and -realtime
[04:04] <ajwill> okay well there's no xruns and it does pop up with that error every time, but it still works fine so I wont worry about it
[04:04] <holstein> http://jackschnippes.freeunix.net/index.php/2010/11/04/lowlatency-kernel-and-realtime-kernel-for-ubuntu-10-10-maverick
[04:05] <holstein> ajwill: JACK will just remember that 'messages' window status
[04:05] <holstein> that it is open
[04:05] <holstein> ALSO
[04:05] <holstein> im not running 10.10
[04:05] <holstein> so it could be something funky in that JACK verion that im not aware of
[04:06] <ajwill> could be...
[04:06] <holstein> ajwill: if your running 10.10, check out that link later on if you want to run a realtime kernel
[04:06] <ajwill> oh haha I just tried running with a lower frames/period and it didnt work...
[04:06] <holstein> in 10.04, you can install linux-rt
[04:06] <holstein> ajwill: yeah, its a lot to ask of an onboard card
[04:06] <holstein> and a generic kernel
[04:07] <ajwill> how much does a non-on board card cost?
[04:07] <holstein> totally depends
[04:07] <holstein> the maudio delta 1010lt is resonable
[04:07] <holstein> has 2 mic preamps
[04:07] <holstein> 10 channels in total
[04:07] <holstein> not balanced though
[04:07] <holstein> and no phantom power
[04:07] <holstein> otherwise i would have got one :)
[04:08] <ajwill> ahhh haha
[04:08] <holstein> i think they are around a buck fifty US
[04:08] <holstein> really nice quality for the $$ and good support
[04:08] <ajwill> only a buck fifty? or as in $150?
[04:08] <holstein> yeah
[04:08] <holstein> $150
[04:08] <ajwill> oh haha
[04:08] <holstein> or so
[04:08] <ajwill> had me excited there :P
[04:09] <holstein> i like the idea of the zoom H4
[04:09] <holstein> 2 nice mics onboard
[04:09] <holstein> 2 other nice preamps
[04:09] <holstein> balanced phantom power
[04:09] <holstein> stand alone mode
[04:09] <holstein> works well in JACK
[04:09] <holstein> i think they are around $300
[04:09] <ajwill> okay new problem!
[04:10] <holstein> im not bit into USB devices though
[04:10] <holstein> i have a presonus firepod
[04:10] <holstein> you can get one under $400
[04:10] <holstein> 8 balanced mic pre's :)
[04:10] <holstein> ajwill: whats up?
[04:10] <ajwill> qjackctl wont rn
[04:10] <ajwill> *run
[04:10] <holstein> ajwill: what did you change?
[04:10] <holstein> try and set it back to
[04:10] <holstein> 512/3
[04:11] <holstein> or 1024/3 even
[04:11] <ajwill> I changed the frames/period and then it froze when I tried to start it, now I cant open it again
[04:11] <holstein> jack is one of those things you kinda have to live in for a bit
[04:12] <ajwill> oo success! I got it to run at an under 20ms latency...
[04:12] <holstein> ajwill: sweet :)
[04:12] <ajwill> one more attempt at lowering it to 256/2...
[04:13] <holstein> dont worry too much about latency
[04:13] <holstein> i say
[04:13] <holstein> i have a couple different JACK profiles
[04:13] <holstein> i have one thats around 2ms
[04:13] <holstein> 1.7 or so
[04:13] <holstein> i use that for live stuff
[04:13] <holstein> usually im tracking at around 11ms
[04:13] <ajwill> ah
[04:13] <holstein> and mixing at more like 40ms or more
[04:13] <ajwill> thats pretty good then I have.. 17.4ms working
[04:14] <holstein> ajwill: you'll really see when you start opening jack apps
[04:14] <holstein> and connecting things
[04:14] <holstein> how stable it is
[04:14] <holstein> i think 20ms would be ideal for you
[04:14] <holstein> with that kernel and card
[04:14] <holstein> for now
[04:15] <ajwill> okay, then I'll get it back down to 20ms so it doesnt crash when I open a program :P
[04:16] <ajwill> do you think 34ms is fine? because when I run it at 24 I get a couple messages saying something about xruns
[04:18] <ajwill> ??
[04:18] <ajwill> owait nvm I get a thing saying "xrun of at least 2.418msecs" even at 34.8ms...
[04:19] <holstein> ajwill: i think you can get under 30 with a different kernel later
[04:19] <holstein> BUT i think even 60ms wouldnt matter much right now
[04:19] <holstein> i would just get it stable
[04:19] <holstein> and play around with some things
[04:19] <ajwill> okay
[04:19] <holstein> to be honest
[04:19] <holstein> i find over 12ms to be a bit un-tolerable
[04:19] <holstein> with soft synths
[04:20] <holstein> so i wouldnt sweat it right now
[04:20] <ajwill> what's a good recording program? I've tried ardour and I dont like that you cant have it click in before you start
[04:20] <holstein> AH
[04:20] <holstein> you can
[04:20] <holstein> ajwill: ardour has a crazy learing curve
[04:20] <holstein> that what i use though
[04:21] <holstein> ajwill: check out #opensourcemusicians
[04:21] <holstein> lots of folk use different DAW's there
[04:21] <holstein> and talk about them
[04:21] <ajwill> hm okay
[04:21] <holstein> qtractor
[04:21] <holstein> renoise
[04:21] <ajwill> well one question I have
[04:21] <holstein> i dont think audacity is a good option
[04:21] <ajwill> is it possible to get a like 8 beat click in with ardour?
[04:21] <holstein> ajwill: sure
[04:21] <ajwill> and I totally agree with you on that one
[04:22] <ajwill> how? I need that and once I have that ardour will be fine
[04:22] <holstein> its possible to que hydrogen drum machine up
[04:22] <holstein> have it play 8 bars
[04:22] <holstein> before you track in ardour
[04:22] <holstein> 8 beats *
[04:22] <ajwill> would you suggest just starting with ardour and using it?
[04:23] <ajwill> or should I look for something more user friendly? like jokosher?
[04:23] <holstein> ajwill: i cant really say
[04:23] <holstein> i find its the best tool for me
[04:23] <ajwill> what kind of recording do you do?
[04:23] <holstein> and #ardour is *so* helpful
[04:23] <holstein> ajwill: mostly live stuff
[04:23] <holstein> not midi
[04:24] <holstein> http://holstein.shacknet.nu/rupert/
[04:24] <holstein> ^^ thats the most recent thing im mostly done with
[04:25] <ajwill> hm, thats rlly good!
[04:25] <holstein> thanks :)
[04:26] <holstein> turned out pretty well i think
[04:26] <ajwill> my limit atm is just doing home recording for youtube covers and such :P
[04:26] <holstein> cool
[04:27] <holstein> you might enjoy the community over at #opensourcemusicians
[04:27] <ajwill> I probably would haha, maybe I'll go there to get advice on a daw to use...
[04:28] <ajwill> so is opensourcemuscians an irc for linux musicians?
[04:28] <holstein> theres a guy that was doing 'pomplamoose' esque vids
[04:28] <holstein> really good ones :)
[04:29] <holstein> ajwill: yeah, its on freenode
[04:29] <holstein> just /j #opensourcemusicians
[04:29] <holstein> or /join
[04:29] <ajwill> joined
[04:29] <ajwill> hmm
[05:35] <_pg_> I just installed a slew of updates on my persistent usb install and now there is a login screen, the credentials "ubuntu" and "blank" seem to try to login but then it blanks back to the login screen. Any ideas?
[05:37] <holstein> _pg_: can you use an older kernel?
[05:37] <holstein> i think you push shift at some point
[05:37] <holstein> to see grub2's list
[05:37] <_pg_> holstein: hmm, ill try that
[05:37] <_pg_> holstein: thanx
[05:37] <holstein> worth a try :)
[10:40] <domjohnson> Hi
[10:41] <domjohnson> Has anyone got an Intuos4 working in 10.10?
[11:40] <hxod> Hello, I work in a kind of indepent project of art production in the brazilian amazon. Then, I wanna try ubuntustudio, but Gnome is "freezed" here. Does anyone have any clue, please?
[11:59] <hxod> Does anyone could help? The system boots normaly, I login, and then the background's screen appears (normaly), I can move the mouse, but there are no panel and nothing else (eventhough I can change to desktop 2, 3 and 4. :P
