AngelofThunderhi everybody02:45
AngelofThunderi have a problem with the mbr and grub...02:46
orngjce223You may want #ubuntu02:49
orngjce223There are less people in here and we don't do stuff with the boot process02:50
AngelofThunderi have severall linux versions installed, and after installing the last one, the ubuntustudio wasnt mentioned anymore in the grub bootloader, so i tried to reinstall grub with the ubuntulivedvd, but theres no list anymore, with fatal error showing no such directory, an than loading automaticly ubuntustudio, without the choice for the others!!! Can anyone help me please?02:50
AngelofThunderaha? who can help me than instead if nobody here can? :-(((02:51
AngelofThunderhey orngjce those people from ubuntu reffered my to here as they found the problem was one of ubuntustudio?02:53
holsteinAngelofThunder: whats going on?02:55
orngjce223?02:55
AngelofThundersearching for solution to my problem holstein?02:55
orngjce223We don't do anything with the mbr or grub02:55
orngjce223:c02:56
AngelofThunderis there a specialised channel for grub mbr or mutlitboot problems?02:56
holsteinAngelofThunder: well, what orngjce223 is trying to say is, that grub is generic02:57
holsteinyou can go to any #ubuntu channels02:58
holsteinBUT, whats going on?02:58
* holstein reading02:58
AngelofThunderwhat do you mean with whats going on holstein, cant follow?02:58
holsteinAngelofThunder: what ubuntu live DVD did you try and use to recover grub?02:59
holsteinAFAIK, there is no ubuntu live DVD02:59
holsteinonly CD"s02:59
AngelofThunderthink the latest02:59
AngelofThunderor almost02:59
holsteinAngelofThunder: right, it shouldnt be a DVD02:59
AngelofThunder10,1002:59
holsteinAngelofThunder: go and check02:59
holsteinyou'll need a *normal* ubuntu live CD02:59
holsteinand you can recover grub02:59
AngelofThunderhmmm i was burning the image to a dvd but ok lol03:00
holsteinAngelofThunder: you can burn to whatever you want03:00
holsteinbut the size matters03:00
AngelofThundereven after the reinstall of it?03:00
holsteinif you say 'i downloaded a 1.2 gb iso03:00
holsteini say, you didnt get the ubuntu live CD image03:00
holsteinthats why im asking you to reiterate what you downloaded03:00
holsteinAngelofThunder: how about this... let me tell you what iso to get...03:01
holsteinhttp://releases.ubuntu.com/lucid/ubuntu-10.04.2-desktop-i386.iso03:02
holsteinburn that to DVD or CD or whatever, and refer to...03:02
AngelofThunderubuntustudio flavor of ubuntu from the official ubuntustudio.org site version 10.1003:02
AngelofThunderwhat does this iso have what my other versions dont have?03:03
holsteinhttps://help.ubuntu.com/community/Grub2#Reinstalling GRUB203:03
holsteinAngelofThunder: ubuntustudio is not live03:03
holsteinyou cant easily recover grub with it03:03
holsteinyou cant easily do that with any of the alternate installers, such as the server installs03:04
holsteinAngelofThunder: what does your hard drive look like?03:04
AngelofThunderok i see03:04
holsteindoes it look like all the installations are there?03:04
holsteinand nothing is out of place?03:04
holsteinget that live cd, and run in a terminal03:04
holsteinsudo fdisk -l03:05
holsteinmake sure that looks like what you expect it to03:05
holsteinthen, use a live CD (like the one i linked) and use that link for grub203:05
holsteinAngelofThunder: actually, what is happening now?03:05
holsteinwhen you boot?03:05
holsteinAngelofThunder: what installation installed grub?03:06
AngelofThunderwhat i meant was after the ubuntustudioline in the bootloader had disappeared, i was reexecuting the ubuntustudio install in rescue mode, and from there reinstalled grub, so that it might have been overwritten!?03:06
holsteinAngelofThunder: either way, if the partitions are still in place, you *can* recover it03:06
AngelofThunderok03:07
AngelofThunderso the fdisk thing i could try with my live gparted, as well? and try recover it...03:07
holsteinAngelofThunder: fdisk -l is literally going to list your partitions03:08
holsteinits not going to do anything else03:08
holsteinif i were you, i would want to see each linux partition03:08
holsteinconfirm that its where i think its supposed to be03:09
holsteinthen, i would know that grub can be made to see them03:09
holsteinotherwise, you've done something more destructive to the disk than what you are aware of03:09
AngelofThunderok the partitions are still as follows03:10
AngelofThundertheres one harddisk on sda03:11
AngelofThunderfollowing partitions03:11
holsteinwell, it wont do any good to list them to me03:12
holsteinunless you tell me what is supposed to be there03:12
holsteini know what my disks look and are supposed to look like03:12
holsteinand i can help you figure that out if you'd like03:12
holsteinAngelofThunder: you can just copy and paste that output to http://paste.ubuntu.com/03:13
holsteinand tell me what is installed where and why03:13
AngelofThundersda1 as generall swap partition, sda2 with ubuntustudio, sda3 with mythbuntu and on extended but same disk, sda5 ubuntu easypeasy and finally sda6 as data as empty fat32!? all for testing purposes, but after the last distro on sda5 installed, grub didnt list ubuntustudio on sda2 anymore, thats why i reinstalled grub with the ubuntustio installation cd hopping that it will rewrite the lost...03:19
AngelofThunder...entry with ubuntustudio to the grub bootloader but the result was a fatal error of modprep couldnt find no such filedirectory and after few seconds automatically loading ubuntustio!!! Hoping that was what you wanted to know holstein!??03:19
holsteinAngelofThunder: also, for the futute03:20
holsteinfor the most part, all of the buntu's are the same03:20
holsteinfor example, you have mythbuntu installed03:21
holsteinyou want the audio stuff from ubuntustudio, you run03:21
holsteinsudo apt-get install ubuntustudio-audio03:21
holsteinOR, you just install the packages you want03:21
holsteinlike sudo apt-get install jack ardour, whatever03:21
holsteinif i want the myth frontend, i dont *have* to install mythbuntu and dual boot03:22
holsteini can just install that in my ubuntustudio install, or a normal ubuntu install03:22
holstein!vanilla03:23
ubottuTo install Ubuntu Studio on top of a vanilla Ubuntu install, read https://help.ubuntu.com/community/UbuntuStudio/Installation03:23
holsteinanyways.. im not sure whats going on AngelofThunder03:23
holsteini can tell you the way i do it03:23
holsteini have a testing laptop03:23
holsteini have 10.04 on there03:23
holsteini shrank the partition and put 10.1003:23
holsteini did *not* install grub from that 10.10 install03:23
holsteini then booted back into 10.04, ran sudo update-grub , and all is well03:24
holsteini did that same procedure when i installed 11.0403:24
holsteinif i ever want to get rid of 10.10 and 11.04, i'll just remove the partitions, and resize over them, and run sudo update-grub from 10.04 again03:24
holsteinAngelofThunder: for you, im not sure what you did to break grub, but i assure you, if those linux partitions are intact03:25
holsteinyou can recover them03:25
holsteinand this says how https://help.ubuntu.com/community/Grub2#Reinstalling03:26
AngelofThunderok thank you very much holstein, will try all that and see if it works maybe this command of sudo update-grub will also solve the problem... thank you anyway03:28
holsteinAngelofThunder: if you can get into *any* of those installs, it should03:29
AngelofThunderyeah i can get into ubuntustudio so may i try this first before reading the grub link lol ;-)03:30
holsteinAngelofThunder: theres also other bootloaders03:31
holsteinplop03:31
holsteinGAG03:31
AngelofThunderbut by the way an other question why is there still no livedvd of ubuntustudio, thougt i was trying before this to install the iso simply by unetbootin on the usbdrive with no success at booting, lol!?03:33
AngelofThunderthis was by the way the reason why i installed it to test and to finally see if ubuntustudio, artistx or puredyne would be the best choice!? :-)03:34
holsteinAngelofThunder: well, there are lots of live ubuntu based distros03:38
holsteinhopefully, by 12.04 we will have a live installer03:39
holsteinif you are interested03:39

holsteinalso, AVlinux is debian based and live03:40
holsteinits all the same stuff though pretty much... JACK and ardour and the usual suspects03:41
AngelofThunderyeah your right thank you but this is just one of the major problems of linux theres a very large choice of distros instead of one which does it all, and finally always lets open the big question of which is best, even that there are just details, but those details of package contents make it very hard to take the best decision! :-)03:44
holstein?03:44
holsteinits linux03:44
holsteinyou can make the one that you want for yourself03:44
holsteinas soon as you make that perfect distro that does it all, someone else will complain to you about what you got wrong ;)03:45
holsteinyou cant please everyone03:45
holsteinlike i said, its linux... the best you can do is just learn the tools, i suggest starting with JACK03:45
holsteinand go from there in the analog or MIDI direction03:45
AngelofThunderyeah thats right03:46
AngelofThunderby the way is there anywhere a list with all avaibale commands such as update grub sudo and so on, which i could look up in case i would be in trouble again, and finding a fast solution?03:53
holsteinthat wiki link is great..03:54
holstein!grub203:54
ubottuGRUB2 is the default Ubuntu boot manager since 9.10 (Karmic). Lost GRUB after installing Windows? See https://help.ubuntu.com/community/RestoreGrub - For more information and troubleshooting for GRUB2 please refer to https://help.ubuntu.com/community/Grub2 - See !grub1 for releases before Karmic (9.10)03:54
AngelofThunderno i meant in generall for linux not specifique as for grub lol03:56
AngelofThunderby the way your command sudo update-grub worked great, everything works now as it should, thank you very much again, holstein! :-)03:58
holsteinAngelofThunder: :)03:59
holsteini forget about that sometimes03:59
holsteinthats the easy first step thing that sometimes i assume folks have already tried03:59
holsteinAngelofThunder: for commands, i think its a good idea to get in mind a task, and then just google, or come in here and ask04:00
holsteini have a sever machine04:00
holsteinheadless04:00
holsteinthat was the purpose of it, to teach me the CLI04:00
holsteinforce me to use it04:00
AngelofThunderlol you see its always those neat little thinks to find to make something work04:00
holsteinwell, it *should* have worked after the install04:01
holsteinnot sure what happened there04:01
AngelofThunderlol i was thinking it would be eassier to have a list with all the commands thought only reading this one, most people should figure out just by the logic of the command name which one should solve there problems! :-)04:02
orngjce223Here's a cool command04:03
orngjce223"apropos"04:03
orngjce223You can use it to search for what command you should actually use04:03
orngjce223like "apropos font" or "apropos rss"04:04
* holstein high-fives orngjce223 04:04
holsteini didnt know about that one04:04
orngjce223Awesome04:04
holsteinorngjce223: is that only installed apps?04:05
holsteinor does it suggest things from the repo?04:05
orngjce223Last I checked it includes the repositories04:05
holsteinhandy04:05
orngjce223I guess you could do the same thing with apt-cache search too if you wanted04:05
orngjce223"apt-cache search internets"04:05
holsteini use apt-cache search a lot04:05
orngjce223Mmhm04:05
orngjce223I think apropos specifically returns commands instead of package names though04:06
orngjce223So it's useful in some circumstances04:06
AngelofThundersomeone suggested simply tap twice tab and than ym lol:-)04:07
orngjce223hahaha04:08
AngelofThunderok thanks a lot for the help guys, wish you a nice day and maybe read ya soon again! bb04:09
holsteinAngelofThunder: laterx04:09
=== rojo_ is now known as sikil
sikilhola raza... greetings from mexico.04:40
orngjce223Hello04:40
sikili'm new to ubuntustudio and i just tought to come and say hi and see how many people where over here...04:42
fladdhi there21:33
holsteino/21:33
fladdquick question: what is the current rt/realtime/lowlatency kernel situation? Which one to use and where to get it from?21:33
holsteinfladd: depends21:34
fladdon what?21:34
holsteinfirst... do you need it21:34
holsteinthen, i say, try them in order21:34
holsteintry the -generic21:34
holsteinif you get xruns, or want lower latency21:34
fladdyes, I want my audio latency to go below 10 ms21:34
holsteintry -lowlantency21:34
holsteinif you get xruns, or want lower latency21:34
holsteintry -realtime21:34
holsteinfladd: why do you want sub 10ms?21:34
holsteinrealtime effects processing?21:35
orngjce223I believe the one in the ubuntustudio repositories is called the -preempt kernel21:35
orngjce223it's only in the ppa that they're called -lowlatency21:35
holsteinorngjce223: we actually dont have one in the repos21:35
orngjce223Oh?21:35
orngjce223I think I installed it before21:36
holsteintheres an -rt kernel in the 10.04 repos21:36
orngjce223I may be wrong21:36
orngjce223Hm21:36
holsteinbut, yeah, you'll need a PPA for -lowlantecy or -realtime21:36
holsteini actually get better performance with the -generic kernel with one of my USB interfaces21:36
holsteinanyways.. heres what the debian team says about it fladd21:36
holsteinhttp://wiki.debian.org/DebianMultimedia#Realtime_kernel21:36
holsteinso eventually, we wont need a different kernel21:37
holsteinhere are the 2 ppa's i suggest21:37
holsteinhttp://wiki.debian.org/DebianMultimedia#Realtime_kernel21:37
holsteinoops21:37
orngjce223Hehe21:37
holsteinhttps://launchpad.net/~abogani/+archive/ppa21:37
fladdwell, if the generic can do what I want, even better. let me try it right now, hang on a sec...21:37
holsteinhttps://launchpad.net/~kxstudio-team/+archive/kernel21:38
orngjce223Mm21:38
fladdthink I can get it down to 8.7ms21:44
fladdnot bad for the generic kernel on a netbook with intel hda audio...21:44
holsteinyeah, if you are sweating audio performance with that rig, i say get a proper interface21:46
holsteinthe signal path upgrade alone is worth more effort than whatever you do software-wise21:46
fladdproper interface is another sad story on linux unfortunately!21:47
fladdI have an emu tracker pre, which can only do 16bit on linux...21:47
holsteinnah, theres plenty of great interfaces21:47
holsteinpresonus firepod21:48
fladdalso recent ones? usb?21:48
holsteinforcusrite21:48
fladdI looked for one lately and could not find a single one!21:48
holsteinfladd: i dont like USB21:48
holsteini dont think USB is designed for audio21:48
fladdmaybe not, but my netbook is not designed for firewire :-)21:48
holsteinyeah, i got an early HPmini with an express card slot21:49
holsteinBUT, i think its arguable that a netbook is appropriate for audio anyways21:49
holsteini dont edit on mine21:49
holsteinbut tracking works quite well21:49
holsteinanyways... there are nice USB options too21:49
holsteinzoom H421:49
fladdI mean, when I am at home at my desktop PC and want to make music only I can boot into XP for that. But on my netbook, just for some quick recordings on the run in decent quality, man, that would be sweet!21:49
fladdthe h4 is a handheld recorder...?21:50
holsteinthe zoom H4 has nice pres and can be used stand alone or as an interface21:50
holsteinhas 2 nice pres and 2 decent on board mics21:50
fladdas an interface? really ,didn't know that...21:50
fladdso it is class compliant?21:50
holsteinyou should ask in #opensourcemusicians21:51
holsteincouple guys over there actually have them21:51
fladdand can I use the built in mics when in interface mode to record with those to my  computer?21:51
holsteinive just heard the pre's and liked them21:51
holsteinand its a lot of kit for the $$21:51
fladdokay, cool. have heard some not so good things about zoom lately...sound quality wise I mean,...21:51
holsteinfladd: AFAIK, its a 4 channel interface21:51
fladdwow, that thing is freakin expensive!21:53
holsteinyeah?21:53
holsteinprice some decent preamps21:53
holsteini have a presonus eureka, it was about $50021:53
fladd330 euro (480 dollars), I think that is too much21:53
holsteinthats just one channel21:53
holsteinno interface21:53
holsteinjust a nice pre21:53
holsteinnice preamps cost $$21:53
fladdmy emu tracker pre was 150 euro and the pres are probably way better21:53
holsteinmaybe you dont need nice pres21:54
fladdas I said, the pres of the emu are extremely good compared to even more expensive stuff21:54
fladdcheck the reviews21:54
holsteinid have to hear them21:54
fladdprobablu21:54
fladdy21:55
holsteini generally consider USB sub-par21:55
fladd?21:55
holsteinsubpar? like not good21:55
holsteini have a few USB interfaces21:56
holsteini use them for stereo recording or whatever when im too lazy to haul the big rig21:56
fladdI see21:57
holsteinmaybe thats all you are interested in though21:57
holstein1 or 2 channels at a time21:57
holsteinline level inputs21:57
fladdyeah, the emu is pretty cool, unfortunately the windows drivers are the worst peace of software I have seen in a while21:57
holsteinyou can get some nice clean kit for that purpose for cheap21:57
fladdand under linux only 16bit, which is a shame as well21:57
holsteinnah21:58
holsteinwhats wrong with 16bit?21:58
holsteini bet you cant hear the difference21:58
holsteini cant21:58
holsteinbetween 16 and 2421:58
fladdclean? probably not, no, but it sure makes a (at least mathematical) difference when appying effects21:58
holsteinand, after it makes it down to mp3 for todays standard market, who would notice?21:58
holsteinfladd: nah21:59
holsteinits just 16bit21:59
fladdI am certainly not one of these "96khz/24 bit is best, I can hear it" guys :-)21:59
holsteintrack it, dither it up21:59
holsteinand do the effects21:59
holsteinfladd: i argue no one can A/B 16 and 24bit21:59
fladdI settled for 44khgz lately, after realizing that my mic cant go over 20khz anyway :-)21:59
holsteini track 24 44.121:59
holsteinno good reason though21:59
fladdyes, I do the same21:59
holsteini'll be dammed if i can hear a difference22:00
holsteinif my rig was locked at 16bit, i wouldnt be losing any sleep22:00
fladdinteresting...22:00
holsteinand like i said, the target is usually mp3 these days anyways22:00
fladdI somehow have this weird feeling that it does matter when recording a lot of channels (one after the other, though) and mixing them with effects22:01
holsteinwell, it matters if you can hear it22:01
holsteinotherwise, who cares22:01
holsteinand22:01
holsteinif you're worried about it at that stage22:01
holsteindither it up22:01
holsteintrack at 16bit22:01
holsteinup convert them to 24/9622:01
holsteinmix and add effects22:01
fladdBut this should not be an argument. I mean, if you go this route, then probably 22khz and 12bit is enough for those ipod kiddies...22:01
holsteinthen, dither it back down again22:01
holsteinnah, theres a point where you can hear it22:02
holsteinwhere the effected frequencies are audible22:02
fladdover integrated speakers of a mobile phone (kids where I come from seem to have forgotten about headphones these days)?22:02
holsteinBUT, we could argue about how many people would actuall noitce the difference22:02
holsteinanyways, 16bit is what we all settled on22:03
holsteinthats still the industry standard22:03
holsteinCD's are arguably the highest quality media we would be targeting22:03
fladdprobably. I think a lot of the music I like went through old akai samplers (12 bit) anyway. So if this is what I compare my own music to, I shall be fine :-)22:03
holsteinmaybe you do an HD DVD or something22:04
fladdon the other hand, CDs are of course tracked way better, only dithered down in the end!22:04
holsteinmaybe now22:04
fladdexcept the akai sampler stuff of course, but vocals or instruments for instance22:04
holsteinbut, it wasnt long ago that wasnt true22:04
fladdbefore it was analogue up to the master!22:04
holsteinlots of studios just go right to CD too for the master22:05
holsteinwell, maybe not lots of them, but i know of one locally and im aware of others22:05
holsteinALSO, in my scenario, you get to make music22:06
fladd:-)22:06
holsteinin yours, you get to set around waiting, or spend money, or wait on some other excues22:06
holsteinexcuse*22:06
holsteini say, go for it... use what you got22:07
holsteinhave fun with the equipment at hand22:07
holsteintheres lots of great albums made with some funky gear22:07
fladdthat actually is a very good point! I am definitely suffering from this! no question about this. Last time I made some real music was at least 1 year ago.22:07
fladdSince then I am mainly thinking about if my equipment is what I want it to be.22:08
holsteinwell, i want some gear too, but i got nice signal path with the firepod22:08
holsteinim working on getting an anolog console22:09
holsteinsome nice RME adat cards22:09
holsteinand some nice A/D converters with balanced line ins and outs22:09
holsteinwe'll see how long that takes22:09
fladd:-)22:09
holsteinbut, in the meantime, the firepod is more than exceptable22:09
fladdsounds good22:09
holsteinyeah, i have a 2 or 3 stage purchase in mind22:11
holsteinget the RME card22:12
holsteinthen, get a berringer A/D22:12
fladdbehringer???22:12
holsteinand save up for the RME thats 10x's the price22:12
holsteinthe behringer will give be 8 channels22:12
holsteinthen the really nice one will give me 8 proper channels22:12
holsteinand the beringer can be for channels 9-16 :)22:13
fladdbehringer has a reputation for bad quality, though22:13
holsteinwhich, in my space, probably wont come up that often22:13
holsteinfladd: yeah, but i cant get the whole thing in one go22:13
holsteinits too much22:13
holsteinill have to go in stages22:13
fladdthat makes sense, sure22:13
holsteinand, i think it'll still be a step up from what i got22:14
holsteinanyways, thats for later... assuming i get the console22:14
fladdI am thinking about getting a nice little mini mixer (like the soundcraft notepad) as a central hub for my mini-studio :-)22:14
holsteinsure, i had a cheapy behringer22:15
holsteini used it as pre's back in the day22:15
holsteinit got stepped down to monitoring22:15
holsteinnow, its a travel PA rig22:15
fladdyeah, I want to route all my inputs for recording to it too. I have two mics, some v-drums, a turntable and so on. right now I am switching inputson the interface all the time, this sucks22:16
holsteinsounds like a nice decent upgrade for you22:17
holsteinand cheap-ish too :)22:17
fladdexactly! This will also give me some very rudimenary monitoring solution, all in one little box22:18
fladdyes, will be less than 250 euro22:18
fladdI just have to decide between the soundcraft, the yamaha and the allen and heath now :-)22:19
fladdand we all know how difficult choices can be22:19
fladdby the way, I just read that changing the max_user_freq under linux can improve latency. is anyone doing this?22:24
fladdall I did is to put rtprio to 99...22:24
holsteinyou can try22:24
holsteinthose tweaks are supposed to be depricated though22:24
holsteinthose guys in #opensourcemusicians know more about that than me22:25
fladdokay, thanks22:25

MrPopinjayIs ubuntu studio switching to xfce with the next release?23:29
ScottLMrPopinjay, that would be the plan23:30

MrPopinjayMarvellous!23:31
MrPopinjayThanks23:31
ScottLi think moving to xfce is a good move, a really fundamentally good move23:31
MrPopinjayHow so?23:32
ScottLMrPopinjay, i think xfce will use less resources than gnome2 or (obviously) KDE23:40
ScottLMrPopinjay, i think also keep within the same desktop metaphor (i.e. panels, hierarchical menus) will serve our users better than gnome3 or unity at this time23:42
MrPopinjayI agree23:44
MrPopinjay+ it suits me fine. I rather like xfce and a distro designed for multimedia nonsense could be good for my DJing nonsense23:45
