* smartboyhw waves at scott-work12:59
scott-workgood morning smartboyhw 12:59
smartboyhwscott-work: If you are here: Who are the ops of #ubuntustudio and #ubuntustudio-devel?13:52
smartboyhwUh oh, FinalFreeze today14:04
scott-worksmartboyhw: i believe i have ops rights for both channels, astraljava as well, maybe holstein as well14:32
ailolen-dt: lowlatency on Quantal has tickless timer by default15:04
ailoAlso, -generic15:04
smartboyhwHey ailo15:04
smartboyhwHey len-dt15:04
len-dtailo, ok, I am just doing some midi testing now.15:04
ailosmartboyhw: How's your documentation work going?15:04
len-dthello smartboyhw 15:04
smartboyhwailo: I need to rewrite it after scott-work's instructions the day before yesterday15:05
ailolen-dt: what sort of testing?15:05
len-dtI think my through stuff is remaking the packets... looking for better hardware.15:05
ailosmartboyhw: Have you shown to anyone yet?15:05
len-dtI have a track on qtractor with 20 notes at the same time.15:06
smartboyhwnope15:06
smartboyhwAs I said I need to rewrite it15:06
len-dtthen I am going out and in and rerecording.15:06
ailolen-dt: rerecording audio, or midi?15:07
len-dtIt looks like the instrument I was using for through is not direct through but reques the notes to go out again.15:07
len-dtmidi.15:07
len-dtThere is an 1/8 note difference from note one to note 2015:08
ailosmartboyhw: Well, if you really think so. Otherwise, just show it, so we can give feedback. 15:09
smartboyhwailo: I have deleted the whole thing and rewrited it!15:10
smartboyhwrewriting, I should say, not rewrited15:11
smartboyhwlen-dt: How's your MIDI?:)15:17
scott-workhmmm, i'm not sure what i said that would cause you to delete and completely rewrite your documentation, smartboyhw :/15:19
smartboyhwIt did:):(15:20
smartboyhwThe original one was to just promote software15:21
smartboyhwThe new one was to create a scenario and be a fluid introduction to actually do it15:21
ailoscott-work: I think what you were talking about with him was a good starting point for documentation, namely writing up a workflow example of what he deos16:06
ailoI think that might be the best place to start16:06
ailoI'm also a bit concerned with the work load of writing workflows, at least if we want to have a complete set.16:08
ailoWhich is why I'm focusing on basic user guides to begin with16:09
ailoThat is really what I eas requesting from smartboyhw16:09
ailoI don't have a clear picture of how a basic user guide would look like for publishing though16:10
ailoOther than showing which applications to start16:11
ailofor audio, there's the obligatory introduction to linux audio16:11
ailoFor graphics, video, publishing and photography, I think at least for three of those there's things like monitor calibration16:11
ailolen-dt: Been using the -rt kernel on Debian now for a couple of days16:15
ailoCan't say I'm too impressed16:15
ailoBuilding kernels now, btw16:15
Len-nbailo, I am not seeing any timing problems with or without tweaks using a USB midi port and qtractor out to record at qtractor in.16:15
Len-nbAll I am seeing is the delay the midi IF is adding because of the serial speed16:16
Len-nbqtractor uses alsa midi, so I did everything there.16:16
ailook16:16
Len-nbNothing on using jackmidi16:17
ailoI was going to include alsa midi testing in the testing suite, but I will just focus on audio for now16:17
Len-nbI think I will have to do the same test with a higher system load.16:18
Len-nbAnd more irq activity16:19
holsteinstochastic: mikeh789 is me BTW... i expired from the testers group if you get a ping about that16:24
Len-nbailo, I have 4 softsynths, hydrogen, qtractor all going. cpu freq scaling just once in a while bumps up one step. jack shows dsp as 33-40%.. oh and firefox is running too... about 15 tabs.17:45
Len-nbmemory is heading for swap :P17:46
Len-nbAbout to reboot to stock no tweaks I'll see if it is enough. I may have to set cpu to lowest speed to see anything.17:47
ailolen-dt: Doesn't seem like all cpu freq uitilities set governor for all cores, only the first17:55
ailoMy tweak will set it manually to all cores17:56
Len-nbThe one that comes with ubuntu does. It looks though all cores and sets each.17:57
Len-nbWhat  I am saying though, is that it might be nice to set some thing other than full speed.17:58
Len-nbIn this case I seem to run out of memory before cpu anyway, so why not run one speed up from half?17:58
ailoMakes sense, as long as the governor is set to performance17:59
ailoI mean, set to a fixed frequency18:00
ailobut that's only for the sake of saving power18:00
ailothe RAM problem has more to due with the desktop configuration, and which applications you are using18:01
Len-nbOr how little ram I have18:01
ailoI'm thinking of what to include in -controls as far as cpu freq tweaking goes18:01
ailoCan't include more RAM anyway18:02
Len-nbBTW, ailo, I can't see any trouble with max-user-freq=3072. Cpu usage does not go up, or fan turn on or desktop slow down...18:03
ailolen-dt: Did it improve anything, though?18:04
ailolen-dt: I'm only now looking at userspace control for the cpu freq18:04
ailoAh, never mind18:04
Len-nbStill testing that... so far I haven't got it to break :P even with no tweaks.18:05
ailoseems like my builds are working.  i686 kernel builds should be ready by tomorrow18:06
ailoI'll share using ubuntuone or some other service like that18:06
ailolen-dt: So, it might be interesting to be able to change not only between cpu governors, but also choose a fixed freq?18:09
Len-nbI would say just choose freq. The top freq is the same a performance anyway.18:10
Len-nb*as18:10
ailolen-dt: Except, ondemand will change frequence no matter which to freq you use18:10
ailoAs I've concluded, it is the actual change between frequencies that may introduce xruns18:11
ailoNot the freq itself18:11
Len-nbto use a spec freq, you have to change the gov to user18:11
Len-nbThen set freq18:12
ailoSure? Not just change the top freq in /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq to one of the available frequencies?18:12
ailoMisprint18:15
ailoI meant scaling_max_freq18:15
ailoAnd, no. Doesn't seem like it18:15
Len-nbdownload/install cpufreq18:16
Len-nbuse cpufreq-set18:16
ailoI'd rather not have -controls depend on additional tools18:16
ailoSince it can be done manually18:16
Len-nbYes, but it is faster for testing and explains what things have to set first before others18:17
Len-nbOr with others18:17
Len-nbEven look at the man page online18:17
ailoI'm reading the linux man right now18:21
ailoDoesn't seem to be working on this system18:29
ailoNo errors, but the freq value doesn't stick18:29
ailousing userspace, editing /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed18:30
Len-nbI think the speed can't just be any speed, when I do a cpufreq-info it lists the available speeds: available frequency steps: 1.60 GHz, 1.33 GHz, 1.07 GHz, 800 MHz18:40
Len-nbWhen I set gov to userspace, the speed locks at full (1.6g)18:41
Len-nbI can then set the speed to 1.33g and it stays.18:45
Len-nbailo, there must be something that tells you which speeds your system supports.18:46
ailoLen-nb: How do you check that the cpu freq stayed?18:47
ailoI was using freq-set now, which was not able to do that18:47
Len-nbI have a cpu speed app running18:47
Len-nbalso cpufreq-info tells18:48
ailocpufreq-set*18:48
ailoI don't find anyneed for cpufreq-set in this case. It doesn't do anything other than what I do manually, both reading and writing. Don't know if it has to do with this system, or kernel18:49
scott-workastraljava: are you doing the -release email?18:50
scott-workailo: Len-nb: is there anything that should be mentioned for the -release meeting?18:51
Len-nbfor .1? Not really unless it is we did no changes.18:52
ailoLen-nb: Seems like Ubuntu does things differently. I was using debian, and apparently, the directories aren't the same18:52
Len-nb:)18:53
ailoIt's a little annoying. seems like the debian way is the standard way18:53
Len-nbIt seems i can set my speeds to .8G, 1.33G and 1.6G. Even though 1.07 is mentioned, setting manually to that gets 1.3G18:56
ailoAh, maybe it's because this is a virtual install18:56
astraljavascott-work: Yeah, I'll wrap it up in a few hours.18:56
Len-nbailo, it seems 1.07 is actually just a bit less than that. If I set 1.06g I get 1.07g18:58
Len-nbSetting cpu to half speed seems to take dsp load from 50% to about 60% as compared to ondemand19:10
Len-nb100% cpu load is 100% if the freq is fixed.19:14
Len-nbIn any case, qtractor does not show any improvement that I can see with setting group or freq on the rtc/hpt.19:15
ailoLen-nb: I guess we should think about disabling /etc/init.d/ondemand20:17
len-dtIt has some problems20:18
len-dtThe worst one is that it takes effect 60 seconds after login.20:18
len-dtSo anything done in rc.local is ineffective20:18
ailoSince we don't want it to control the governor, I vote for just removing it20:20
len-dtHow do we do that "correctly"?20:21
ailoDon't know20:21
len-dtProbably running the deal that changes the link to a K9920:22
len-dtI don't think it is just one package that can be blacklisted20:24
ailoI guess we can use -controls to disable it, as soon as someone wants something else than ondemand20:25
len-dtThat would be best. The one for jackdsp sensing seems to just turn preformance on at jack startup20:25
ailoThis should do it: update-rc.d ondemand disable20:26
ailolen-dt: Which one is that?20:27
ailoI mean, the jackdsp sensing thing20:27
len-dtYa that was one I was thinking about.... After you do that though... ondemand will still be there20:28
len-dtlet me check20:28
len-dthttp://rg42.org/oss/jackfreqd/start20:29
len-dtailo, read all the comments, they explain things a bit better.20:29
len-dtthe one " I intent 'jackfreqd' to do the same as you do: switch to20:30
len-dt“high CPU performance” when starting serious audio work and go back to low-power only at the end of the session."20:30
ailolen-dt: I'll see about adding it as a tweak too then20:34
len-dtYou have to set the gov to user.20:35
ailoI picture a toggle for enabling "fixed frequency when jack is running"20:37
ailoSomething like that20:37
ailoIt'll adjust other settings automatically20:37
ailoin -controls20:37
len-dtSo that would replace or at least be instead of jackfreqd20:38
ailoNo, I mean, when enabling jackfreqd, from -controls20:38
ailoIt means we would need to include it somehow in ubuntustudio-controls20:38
len-dtThat only does full speed not a set speed20:38
ailoWell, whatever. I'll see the manual once I have the chance20:39
ailoThe point is, the other settings will adjust automatically20:39
ailoWhen toggling it20:39
len-dtOK20:39
len-dtThere has been interest in using full speed for some graphics/video work as well20:40
ailoFor them, that toggle would not be interesting20:41
len-dtNo but some way of turning it on would be.20:41
ailoThey'd use 'performance', or 'fixed frequency'20:41
ailoI'm adding all of it20:41
len-dtThere are three files in /etc/init.d that deal with cpufreq setup: ondmand, loadcpufreq and cpufrequtils20:43
ailolen-dt: At least cpufrequtils depends on the package with the same name20:45
len-dtThe question is do we want it to run. We may need it to run and then set what we want.20:46
ailoBoth loadcpufreq and cpufrequtils20:47
ailoWe don't need it to set cpu settings20:47
len-dtIt loads the scalling module.20:47
len-dt*scaling20:47
ailoWe should be able to do everything manually20:48
ailoWhich I prefer20:48
len-dtI was goin to say we can replace it.20:48
ailoWe might need to add a "override cpufrequtils"20:51
ailo..toggle20:51
ailoAnd have -controls disable it20:51
len-dtailo, Are you having more than one profile? So the user can save various profiles for different uses.21:24
ailolen-dt: Haven't got that far yet21:26
ailolen-dt: I'm a bit late with this. Just preparing tests for now.21:27
ailoI won't be using jackfreqd for the tests, but I'm keeping it for the implementation of -controls21:27
Len-nbailo, I'm giving up with the MIDI tests for now. I need a controlled situation that shows problems. So far everything i have done shows no problems in timing beyond the limits of the MIDI stream itself.21:37
ailoYea, I will probably not touch that either for the time being21:40
Len-nbI think we should make the timers audio group and give the user the ability to set the maxfreq.21:41
Len-nbMaybe it makes a dif with rosegarden21:41
ailoI'll add the tweak21:44
ailoLen-nb: One aspect of -controls is to have users do testing themselves, and give feedback. After all, we can't test on every possible machine and device21:44
ailoIs what I realized..21:44
Len-nbYa, In any case, I have at least tested for no bad effects.21:46
Len-nbEverything is running happy at half speed.21:47
ttoinehi22:04
len-dtttoine, haven't seen you for a bit22:04
ttoineI was thinking I didn't had any news... and just realised that I may not be in the devel mailing list22:04
len-dtWe were talking about monitor calib22:05
len-dtColourwise22:05
ttoinelen-dt: yes, shoulder surgery and holidays22:06
len-dtOww22:06
len-dtsounds painful22:06
ttoineit was very modern surgery, so only two small points, but yes, it is painfull22:07
ttoinecan someone tell me how to get again de mailing list ??22:08
len-dtI remember years ago, I had a pin put in my knee... the sprained toe I had at the same time hurt more.22:09
len-dtThere is a link on the web page... I'll find it.22:09
len-dthttps://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel22:10
ttoineok, just applied22:11
ttoinethanks, len22:11
len-dtN P22:11
ttoineIt will be easier to follow and participate, I guess22:13
len-dtThere are some blue print things Scott says you asked for... replacing argyl for example.22:13
ttoineah yes, great. you know where I can find that on the wiki or something like that ? on it is only on the mailing list ?22:15
len-dtThe blue print is at https://blueprints.launchpad.net/ubuntu/+spec/ubuntustudio-q-misc22:15
len-dtWe have both argyll and gnome-colour-manager. The same thing as vanilla as far as I can tell.22:16
ttoineI think it is good to be like vanilla on this point22:18
ttoinebecause we don't have an expert on this point. and we don't need to invent the wheel again, as we say in french22:18
len-dtIt doesn't show up in the menu, but is supposed to start when the colour detector is plugged into the USB(?) port.22:19
ttoineyes22:19
ttoineargyll is used by gnome colour management gui22:20
len-dtOK, hopefully early next week all the stuff we have committed will hit the ISO. so we can see it.22:21
ttoineok22:21
len-dtWe based our workflow on two websites for photography. I don't have the one handy but the other is http://www.rileybrandt.com/2012/07/31/linux-photo-1/22:22
len-dtttoine, I also wanted to ask about this: color - explore making a package for adobe icc22:23
len-dtAre these ICCs for monitors?, printers?22:23
len-dtDo you have a URL for it?22:25
ttoineit could be a good thing22:28
ttoinethere will be mostly printer and standards icc22:28
ttoineI look for the link, wait a bit22:29
len-dtWe already have a package of iccs included. 22:29
len-dtI can wait... I leave something up on IRC almost all the time.22:29
ttoinehttp://www.adobe.com/support/downloads/iccprofiles/iccprofiles_win.html22:33
ttoinethere is only stuff for windows and mac22:33
ttoinebut it is possible to unzip it22:33
ttoineit would be great to add some other stuff in the package, not only adobe icc22:34
ttoinehttp://www.color.org/index.xalter22:35
ttoineyou will find all the icc profiles on this website22:35
ttoineand most of the screen and laptop vendors provide icc profiles for their hardware on their support website22:36
ttoinefor my thinkpad, there is a icc profile available at lenovo22:36
len-dtfrom what I have read it needs to be set up and measured about once a month.... but I would guess those profiles are still closer tahn none.22:37
ttoineyes22:39
len-dtWe ship a package called icc-profiles-free, but there is another package called icc-profiles too.22:40
len-dtDo you know if they are the same or what the difference is?22:40
ttoineI can look at it22:41
ttoinebut currently, most of what is package (for example fogra icc profiles) are for america printing industrie22:41
ttoinefor Europe, it miss the "Iso coated v2" icc profiles22:42
ttoineyou need it in order to create cmyk pdf in Scribus for press22:42
len-dtThe two packages are different. The one we don't ship is smaller and it recommends the one we do.22:42
ttoineok22:43
ttoinefor europe, all that should be available for the printing industry is on this page22:43
ttoinehttp://www.eci.org/en/downloads22:43
ttoinethere are a lot of pdf and a fex zip packages22:44
ttoinelook at the "ICC profiles from ECI" section22:45
ttoine-fex +few22:45
len-dtYa it looks that way. 22:45
len-dtAre they of a license we can package them?22:46
ttoineI am looking for ;-)22:48
knomei doubt.. but haven't checked really.22:48
len-dtThere is a disclaimer about not being responsible ... but lic stuff22:48
knomedefault ICC profiles would be nice to have, but then again, there are printer-specific profiles too, so rather than trying to include every standard anybody could ever need, rather just make adding the profiles easy22:50
len-dtIt sounds like maybe what we need first is documentation on colour management in general22:51
len-dtBoth with and without a meter.22:51
ttoineyes22:51
knomefirst broad support then docs ;)22:51
ttoinethink that a lot of thing can be done with a basinc screen22:51
ttoinebasic22:51
len-dtAt least these flat screens don't change as much as crts and will stay closer longer.22:52
ttoinewhat we miss the most imho is a way to generate cmyk pdf with cups22:53
ttoinecups pdf at the moment generate only rgb pdf22:53
len-dtttoine, is it worthwhile having something like lprof?22:53
len-dtIs there such a thing as a converter?22:54
knomettoine, yeah. not enough cmyk support is the thing keeping me on win+photoshop for print22:54
len-dtOr is the quality any good?22:54
knomei don't think professionals should rely on converters22:54
ttoinewe don't need lprof if we keep gnome colour gui and argyll22:54
len-dtok.22:55
ttoineat the moment the only "good" way is to import files in scribus and use it to generate a quadri pdf22:55
ttoinethere a is an old tool too, not packaged, wich can turn quadri to rgb, or rgb to quadri, using icc profiles22:56
ttoinebut it is not up to date22:56
ttoinelen-dt, knome: http://www.blackfiveimaging.co.uk/index.php?article=02Software%2F05CMYKTool22:59
ttoineI tried cmyktool and it works well with jpeg and tiff23:00
len-dtI had thought I had heard there was a way to save CMYK in GIMP too, but I can't find it.23:00
ttoinelen-dt: with the separate+ plugin but it is not available on Linux23:00
knomejpeg and tiff ain't pdf23:00
knome:)23:00
ttoineknome: maybe you should try cmyktool and tell us if it is good or bad ?23:01
ttoineknome: yes, there is still the problem of pdf23:01
knomei'll bookmark that, but i don't know when i'll have the time to check that out23:01
ttoinemaybe with a custom ppd file, cups-pdf could generate quadri pdf23:01
knomei don't know how much cmyk jpg and tiff would help the professional without cmyk pdf though23:02
ttoinelen-dt: do yo want me to try to contact the eci.org staff to get licence information  ?23:02
len-dtMost of this is over my head.23:02
len-dtSure, but the reality is that someone would have to package and maintain it.23:03
knomemaybe add to the same package that has the US standards, and ask its maintainer to maintain those too23:04
knomeif it looks like it's too much work or work nobody wants to take care of, just leave it23:04
len-dtAnd we are a small group. Some one has offered to package gimp-paint-studio for ubuntu repos, but I think at this point it may not make 12.10.23:04
knomejust make adding profiles trivial23:04
knomeor write a good tutorial23:05
len-dtThat was why I said docs...23:05
ttoineknome: sometimes you just need one or two profiles.23:05
knomepro's probably need to add custom profiles anyway23:05
ttoineso providing links could be a good start23:05
knomeyes, that's a start23:05
ttoineand the different places where to put the files23:06
knomeyes23:06
knomethat would be next to extremely helpful23:06
ttoine~/.color/icc23:06
ttoinefor gnome colour management23:07
ttoinebut for scribus, etc... it has to be done with sudo23:07
knomeother way to get moving is to make apps use standard places for profiles23:08
ttoineknome: the gnome colour management system is very young and some apps are still looking for xicc, or even older places23:09
knome.config/icc or sth like that would't sound bad23:10
ttoine.colour/icc23:10
len-dthow do I start gnome color manager?23:10
ttoinesystem preferences23:10
knomettoine, that works for me too, as long as every app uses it ;)23:10
ttoinethen click on the beautiful colour icon23:10
ttoineknome: ok ;-)23:10
knomethe situation probably isn't better on windows actually23:11
knomedoesn't mean we can't/couldn't do it better23:11
ttoine/usr/share/colour/icc23:12
knomemm23:12
ttoineknome: since windows 7, it seems to be well managed at kernell level23:12
len-dtttoine, that doesn't get it for me23:12
knomettoine, wouldn't know about that23:12
ttoineand of course it has always been there in Macos X23:13
ttoinefor it the macos X DE is writen in visual postscript or something like that23:13
ttoinelen-dt ?23:14
len-dtI can't find a way to start the color manager on US 12.0423:14
ttoinehttp://wiki.scribus.net/canvas/Getting_and_installing_ICC_profiles23:16
ttoinelen-dt: vanilla ubuntu ? xubuntu ?23:16
len-dtThey all start with GCM23:16
len-dtubuntustudio.23:16
len-dtObviously I need to add them to the menu.23:17
ttoinelen-dt: can you launch gnome-control-center ?23:18
ttoineI am mostly on vanilla ubuntu23:19
len-dtNo, we have the xfce one.23:19
len-dtI can get things from CLI and the *.desktop files are there... Not sure why they don't show in our menus... something to check.23:20
ttoineok23:20
len-dtSo we have had the color manager, but no menu item...23:22
ttoinein vanilla, it is integrated to the gnome-control-center... I can't even get the command name with Unity...23:23
ttoinewow, neat 1:30 am...23:24
ttoinesee you later23:25
len-dtOne of them is just a MIME box... Bye23:25
knome:)23:25
knomenight ttoine 23:25
len-dtknome, the desktop files are all "nodisplay"23:28
knomelen-dt, re: what? :)23:28
