OvenWerkszequence: loading ubuntustudio metas to lubuntu pulls in a lot of libs.02:31
OvenWerkslubuntu does n't have PA by default... US metas add it though :)03:58
OvenWerksHowever I don't think it would run by default. The user would have to add it to the auto start list on their own03:59
OvenWerksWeird, when I installed lubuntu, I told it to put grub on /sdc, but when I installed the lowlatency kernel, it put grub somewhere else. (sda?)05:26
OvenWerkson reboot, pulse runs with session. So installing the US metas makes pulse the sound server if the user wants it or not :P05:27
OvenWerksAck. Pulse gets installed and runs... but no pavucontrol.05:32
OvenWerkszequence: with reguard to jerky and smooth video.06:01
OvenWerksI had mentioned that US seemed to be jerky and KDE was not.06:02
OvenWerksDid some further testing. Lubuntu is fine, a fresh install of US 13.10 is fine too. The one that is bad is the P install, updated to Q then to R. I don't know if upgrading to S would fix anything though.06:04
OvenWerksTomorrow I will try upgrading this to S and see if it gets any better.06:05
OvenWerksAll tests were with a 3.8.0 kernel, lowlatency, same video app, same video.06:08
OvenWerksHang on... this is weird. my 12.04 that was upgraded to 13.04 has 3.8.0-22 but all the 13.10 installs have 3.8.0-1906:13
OvenWerksThe generic kernel for 13.10 is 3.9.0-2 BTW06:14
OvenWerksSomething is strange with our kernels.06:14
OvenWerksWe seem to have gone back a few kernels for Saucy06:17
OvenWerksI guess I will also have to try a straight up Raring install as well.06:18
OvenWerksholstein: ^^^ it looks like the performance problems are upgrade related or one version of the kernel.06:22
zequenceOvenWerks: saucy doesn't have SRU updates for the kernel15:36
zequenceOvenWerks: Currently, no one is maintaining the development release of the kernel for saucy15:36
zequenceIt's updated a little now and then15:36
zequenceI'm overtaking maintanenace of it this cycle15:37
zequenceOvenWerks: And about jerky video - it makes little sense comparing different DEs on different releases, don't you think?15:37
zequenceAnd also, if one really wants to find out difference in performance, make a comprehensive test, perform it, gather data - then decide what is actually going on15:38
zequenceThings that happen on one machine is not saying much in any case15:38
zequencebesides, saucy should be using 3.9 by now15:53
madeinkobaiaHi all : )16:01
OvenWerkszequence: I thought it was the same kernel, but it is not. Most of my tests were same release. All of the 13.10 installs work fine (including ubuntustudio) which makes sense.19:49
OvenWerksI have heard other complaints about 3.8 as well.19:51
OvenWerksSo, I will try on the bad install, installing the older kernel that Saucy installs. I will try upgrading to 13.10. I will try a new raring install.19:53
OvenWerksIf I get the same thing just with R or just with that kernel, Fine. It is easy enough to avoid one kernel.... and Saucy seems to be fine.19:54
OvenWerksThe big thing I have learned is that DE makes not much difference. I think the KDE devs have done some work since I last used it. Good stuff.19:55
OvenWerksI really would like to try Gnome shell as well, if I can get it to run... even if I have to tweak it a bit before I can login.19:56
zequenceMy experience is the same. DE doesn't matter much for performance. Nothing does, except kernel and certain drivers. Like the graphic driver.19:57
zequenceBloated desktop, or minimal. Not much of a difference19:57
zequenceAnd that's a good thing19:57
zequenceCause, that means, there's not much you need to do in order to tune a system for low latency19:58
zequenceOf course, CPU usage might be worse on bloated desktos19:58
zequenceBut, it won't cause xruns, until you maximize CPU usage19:58
zequencert is rt19:58
OvenWerksRight19:58
zequenceFor someone who wants to install a system for a very specific use case, like a studio recording/mixing system, then there might be cause for wanting to customize it20:01
zequenceor a live processing system20:01
OvenWerksAre we expecting a 3.9 LL kernel for 13.10?20:01
zequenceI don't know what version will be final release. Maybe 3.10. I will be taking over maintenance soon though20:01
OvenWerks(generic is 3.9 just now.)20:01
OvenWerksAh, I had heard about some changes to how HW is handled as of 3.920:02
zequenceA new kernel version is released about every 3 months20:02
OvenWerksBut I have had no trouble.20:02
zequenceUsually, Ubuntu goes with whatever is the latest stable bversion20:02
zequence3.10 is RC right now20:03
zequenceOnce it's released, it'll end up in Ubuntu tooo20:03
zequenceSo, 13.10 might even be including 3.11 by final release20:03
OvenWerksOK20:04
zequenceThe vanilla 3.8 kernel has now reached EOLĂ–20:04
zequenceEOL*20:04
OvenWerksThat will make some people in the audio world happy.20:04
zequenceYou can see the current kernels here https://www.kernel.org/20:05
OvenWerksLooking at lubuntu, I think adding Studio to it will make it a lot less "light"/"Lite"20:06
OvenWerksLubuntu relies on having light applications as well as the desktop.20:07
OvenWerksI think that there may be some audio workflows where it will fit, but suspect some video workflows will not gain anything.20:08
zequenceI'm not aware of any other processes that would be added to Lubuntu, except pulseaudio20:09
zequencelibraries yes, but processes and services that would start when you boot the system20:11
OvenWerksI have found that when I start kdenlive it starts a number of KDE services. They do not stop when kdenlive stops.20:16
OvenWerksThis is true in xfce as well20:16
OvenWerksI don't know that this is a problem or not.20:17
OvenWerksI kind of expect that someone who likes kdenlive might also like the KDE desktop.20:18
zequenceI'm sure the number of processes could increase, if you start up a whole range of applications. But, there's no way around that. If you just use LXDE, and Kdenlive, then that's what will happen. 20:18
zequenceWhy?20:18
zequencekdenlive is one of the most popular video editors on Linux, and doesn't stop people from installing it, who have no interest in KDE20:19
OvenWerksMore a matter of recomending a good install for any given workflow20:19
zequenceOvenWerks: Are you about to rank applications now?20:19
OvenWerksNo :)20:19
zequenceAfter a set of rules you put up, on performance, usability, etc20:19
zequenceAdding the studio metas won't make any system less minimal. Aside from if you think PA is breaking that. This is at least my estimation so far. 20:20
zequenceWhat we could do however, is allow for the user to select metas during installation20:21
zequenceAnd for audio, we should have a core meta too20:21
OvenWerksI think people buy machines based on what they want to do with them. Someone who feels they "require" a light system is not likely to do video editing.20:21
zequenceOne which only includes linux-lowlatency and jack, basically20:21
OvenWerksHaving a meta that has lowlatency would be good.20:22
zequenceWe already have the meta linux-lowlatency20:22
OvenWerksIt would be nice if it adds a rule to grub to default to that kernel too.20:22
zequenceBut, I mean, for the core audio components20:22
OvenWerksYa, I don't know if there are any other of our workflows that need it.20:23
zequenceSo that when you install, you can decide not to install the whole range of applications, if you don't want them20:23
OvenWerksIf we are adding Studio to another install, that should be automatic.20:24
zequenceI'm not following..20:24
OvenWerksMaking it work with our iso and still allowing the live session to showcase all the workflows might be harder.20:24
OvenWerksIf someone installs Ubuntu desktop and then installs our metas, they will only install the metas they want. So that part sortself out.20:25
OvenWerks*sorts itself20:25
zequenceYeah, that's why we have them split20:26
zequenceOtherwise, we would just have had a meta called "ubuntustudio"20:26
OvenWerksRight.20:26
OvenWerksTo work with the live ISO, we have to tell the seeds to show everything in the live session but not install it all. Which we can do. But then to select a workflow to install there needs to be some way of changing the stuff that will install, or include extra packages for later instalation.20:29
zequenceYes, we need to do some ubiquity coding for that. python scripting20:29
zequenceIt's been a plan since last release, to add the meta options20:30
zequenceI'm going to have a look at that later on20:30
OvenWerksTalked about since the first live ISO20:30
zequencehttps://blueprints.launchpad.net/ubuntu/+spec/ubuntustudio-s-installer20:31
OvenWerksI have learned a little python... enough I can make something that works, but not enough to take something already made and understand what the other dev was doing and how I can change it.20:33
OvenWerksWhat they call "enough to be dangerous".20:34
OvenWerksAnyway, I am going to boot to 3.8.0-19 on this machine to see if that makes any difference.20:36
zequenceI like that saying. We should all know enough to be dangerous20:37
OvenWerksmoving back to the 3.8.0-19 kernel did not improve things.20:49
OvenWerksI am either seeing a raring problem or an upgrade problem.20:50
OvenWerksI will see if upgrading to saucy still adds a generic kernel while I am at it.20:54
OvenWerksYes it will.20:55
DarkErai removed those generic kernels but didn't have the time to check in again for updates20:56
OvenWerksFrom what I have seen, the generics kernel just shows up when upgrading.20:56
OvenWerksI have never had one show up on me when doing a fresh install20:57
DarkEraso a upgrade from raring to saucy causes it then20:57
OvenWerksyes.20:57
OvenWerksupgrade from precise to quantal does not20:57
OvenWerksupgrade from quantal to raring does20:58
OvenWerksand from raring to saucy does20:58
OvenWerksSomething has changed in the upgrade script or in one of the depends in a package we depend on.20:59
OvenWerksWe must have done something in our metas to stop it showing up on the ISO though.20:59
OvenWerksBut I don't see it black listed21:00
OvenWerkswe should be able to go through the changes made to the upgrade script/settings during quantal.21:04
zequencehttp://www.linux.com/news/featured-blogs/200-libby-clark/721494-linux-thermal-daemon-monitors-and-controls-temperature-in-tablets-laptops21:06
OvenWerkssounds great.21:10
OvenWerksover heated GPUs is supposedly the biggest kill in those.21:10
OvenWerksA popup notice: "vacuum out your machine dummy" might help too.21:11
zequencemanufacturers could make that a lot easier too21:12
OvenWerksmight sell less21:12
zequenceSome laptops, if you want to clean them from dust, you have to open the whole thing. And, it's not usually an easy thing to do21:12
zequenceI have one, where I just need to open a section21:13
zequenceOne could even create a module for just the dust. Open this, clean it, close it.21:13
DarkErai my case i need to open the bottom panel entirely21:13
zequenceIf you ask me, most engineers and designers are pretty mediocre, and lazy21:15
zequenceOr, their bosses are less than smart21:15
DarkErapossibly :D21:15
DarkErai hope this laptop continues to work for a few more years, i bought it somewhere in june 200821:18
OvenWerksmine is from 2010 or so. First install was 10.0421:19
DarkErafirst install on this machine was 8.0421:19
DarkEraon the packard bell i had i started with 7.0421:20
DarkErathat laptop died after 3 years21:20
DarkErabought it in 200521:20
OvenWerksI still have an NEC from pre2000, pentium 360mhz21:21
OvenWerksWorks as good as it ever did21:22
DarkEracool :)21:22
OvenWerksBattery is long gone of course.21:22
OvenWerksHas an opening on the side for a thing called a "floppy"21:22
DarkErai worked with floppies on school in the '90s21:23
OvenWerksI still remember installing an OS from a scack of floppies.21:24
OvenWerks*stack21:24
OvenWerks6 for DRdos21:24
OvenWerkszequence: my video problems seem to be upgrade related22:40
OvenWerksIf I install Saucy from ISO, video is fine.22:41
OvenWerksIf I upgrade there, no good22:41
