[03:26] <sirriffsalot> I'm quickscanning jack to see why I'm getting surprisingly many xruns.. One of the "not good" results say that I have a kernel without real-time capabilities.. I have a lowlatency kernel:-S
[03:26] <sirriffsalot> When playing songs with vlc, audacious or just regions in ardour, every now and then there is a stream of unbearable xruns.. None whatsoever when jack is not running.. Any ideas on that?
[08:42] <smartboyhw> Hi!
[08:54] <cfhowlett> smartboyhw: greetings
[08:56] <smartboyhw> cfhowlett: Hi
[08:56] <smartboyhw> It's me who should say greeting.
[08:57] <smartboyhw> I'm a Ubuntu Studio team member, after all.
[09:02] <cfhowlett> smartboyhw: either way ... hello.  And may I say US Team Member I am QUITE pleased with the new web site and recent resurgence of US activity.
[09:06] <smartboyhw> OK, I'm new, actually
[09:06] <smartboyhw> I'm for support and testing
[09:06] <smartboyhw> So I need to always be here.
[09:07] <cfhowlett> smartboyhw: hey, maybe you can help.  got a xubuntu user in main channel who needs to force a hardware reset of his wifi...
[09:09] <smartboyhw> cfhowlett: I am not responsible for Xubuntu, only Ubuntu Studio. Sorry
[09:09] <smartboyhw> !support
[09:11] <cfhowlett> smartboyhw: fair enough.  thanks anywayz

[10:59] <_MOSMarauder> hi smartboyhw_away
[12:38] <smartboyhw> HI!
[13:42] <Joao> hello, I heard that the kernel liquorix works better than low-latency kernel. and saw that it is only for debian, but it is possible to install it on ubuntu. If I install the kernel liquorix will have a performance gain in ubuntu studio?
[13:43] <smartboyhw> Joao: Hi
[13:43] <smartboyhw> Joao: I don't think so
[13:44] <Joao> why?
[13:52] <smartboyhw> Well, seriously, we don't recommend so
[14:04] <Unit193> Joao: There are some issues if you select another kernel than the main ones, but it does technically work as I do use it on a computer.
[14:04] <smartboyhw> Unit193: Hi!
[14:04] <Unit193> Check the disclaimer on thius page for example //help.ubuntu.com/community/Kernel/Compile
[14:05] <Unit193> smartboyhw: Something I can help you with?
[14:05] <smartboyhw> Unit193: NO thanks, I'm a member of the Ubuntu Studio Team!

[15:58] <sirriffsalot> Hey, I'm having these frequent streams of xruns, and yesterday I think I've narrowed things down to needing a realtime kernel.. Any comments on that?
[16:22] <holstein> sirriffsalot: you can also relax your JACK settings
[16:22] <holstein> sirriffsalot: sometimes, you can get a kernel, and you can lower your latency and have better performance,and less xruns
[16:22] <sirriffsalot> holstein, not really..  I need pretty low latency:)
[16:22] <holstein> i have a peice of hardware that actually works *much* better with a generic kernel
[16:22] <sirriffsalot> Getting other hardware is not an option for the month to be, so:)
[16:23] <holstein> i can get 2ms latency, where, with the realtime one, it xruns, and crashes at all settings
[16:23] <holstein> sirriffsalot: im not suggesting either
[16:23] <sirriffsalot> On a laptop in mexico, so gonna have to try the realtime one
[16:23] <holstein> sirriffsalot: what im saying is... a kernel is not going to magically make your machine "better"
[16:23] <holstein> you try the realtime kernel.. its a quick and easy download.. and have realistic expectations
[16:24] <sirriffsalot> Ok, wanna tell me where I download it from? Having some trouble getting it:)
[16:24] <sirriffsalot> About to get the KXStudio PPA..
[16:24] <holstein> sirriffsalot: yup.. thats what i would suggest.. its easy and quick
[16:24] <holstein> the kernel PPA
[16:24] <sirriffsalot> KXStudio?
[16:24] <sirriffsalot> Or what ppa in particular?
[16:25] <holstein> sirriffsalot: the kxstudio kernel PPA.. or any with the kernel you'd like to try
[16:25] <sirriffsalot> holstein, can you recommend any relatime kernel?:):)
[16:25] <holstein> sirriffsalot: i know, my first time, i didnt add the PPA, i just goet the .deb's out of the PPA, and installed
[16:26] <sirriffsalot> How do you do that? Haha:)
[16:26] <holstein> sirriffsalot: sure.. the realtime kernel we are discussing currently.. the one falk has packaged.. the one in the kxstudio kernel ppa we are talking about, that you can optionally not use is the one i suggest
[16:26] <holstein> sirriffsalot: you go to the link, and download the .deb's
[16:26] <sirriffsalot> I'm https://launchpad.net/~kxstudio-team/+archive/kernel at the moment
[16:27] <sirriffsalot> I see no way of getting the .deb file
[16:27] <holstein> sirriffsalot: you can right click on the one's you find and want from here
[16:27] <holstein> http://ppa.launchpad.net/kxstudio-team/kernel/ubuntu/pool/main/l/
[16:27] <holstein> from here http://ppa.launchpad.net/kxstudio-team/kernel/ubuntu/pool/main/l/linux-meta-realtime/
[16:28] <holstein> for example...
[16:28] <holstein> wget http://ppa.launchpad.net/kxstudio-team/kernel/ubuntu/pool/main/l/linux-meta-realtime/linux-realtime_3.2.0.23.25~precise1_i386.deb
[16:28] <holstein> for a 32bit machine
[16:29] <holstein> http://ppa.launchpad.net/kxstudio-team/kernel/ubuntu/pool/main/l/linux-meta-realtime/linux-headers-realtime_3.2.0.23.25~precise1_i386.deb
[16:29] <holstein> http://ppa.launchpad.net/kxstudio-team/kernel/ubuntu/pool/main/l/linux-meta-realtime/linux-image-realtime_3.2.0.23.25~precise1_i386.deb
[16:29] <sirriffsalot> You make it seem so easy..
[16:29] <holstein> sirriffsalot: it should take a few minutes
[16:29] <sirriffsalot> Why are you linking this many??:D
[16:29] <holstein> sirriffsalot: you need all 3 AFAIK.. seems like you can have 2
[16:29] <holstein> i try one, when it says "this depends on X".. i install X
[16:30] <holstein> sirriffsalot: you'll need 2 of them IIRC
[16:30] <holstein> sirriffsalot: download all 3 for the version you want/need... install them in one big sweep if you want like..
[16:31] <sirriffsalot> Ah right, hang on
[16:31] <holstein> sudo dpkg -i /path/to/file1.deb /path/to/file2.deb ...so on
[16:31] <holstein> you can then search "linux" in any package manager and easily "undo" what you are doing.. though, you arent going to break anything... you dont remove the other kernel
[16:32] <sirriffsalot> Can't I just open the deb files in synaptic?:S
[16:32] <holstein> i have machines that the realtime kernel breaks wifi on
[16:32] <holstein> i have machines that the realtime kernel wont work in a way i am comfortable compromising with the grahpics cards
[16:33] <holstein> if it "just worked", we would use it, and ship with it... but the lowlatency is a good compromise
[16:33] <holstein> sirriffsalot: you can literally install those howeer you are comfortable
[16:33] <holstein> however*
[16:33] <sirriffsalot> Synaptic it is then(A)
[16:34] <holstein> if you add the ppa, you can just install the meta package.. the linux-realtime or whatever it is falk called it
[16:34] <sirriffsalot> Yeah, I'll try the hard way first
[16:35] <sirriffsalot> Uhm
[16:35] <sirriffsalot> If I try to do it with the terminal
[16:35] <holstein> just depends on what you want... all ways are "easy" or "hard" and you are capable of breaking your system
[16:35] <sirriffsalot> As you showed me: "sudo dpkg -i /home/sirriffsalot/(one of the three packages) I get an error message for every one..
[16:35] <holstein> sirriffsalot: feel free and share any helpful error messages.. i would "auto complete" the path with tab
[16:37] <sirriffsalot> Basically whatever package I attempt installing results in terminal telling me it depends on the other two being configured/installed..
[16:38] <holstein> sirriffsalot: all i can say is, it worked for me... pastebin it if you like... or click on them and make gdebi or whatever its called kick off and maybe help you more than the terminal output is
[16:38] <sirriffsalot> Pastebinning
[16:39] <sirriffsalot> http://pastebin.com/4397RKGw
[16:40] <holstein> sirriffsalot: im suggesting that you do all of them at once
[16:40] <holstein> sudo dpkg -i /file/one.deb /file/two.deb
[16:41] <holstein> you can see how they depend on each other, and wont go by themselves
[16:41] <holstein> sudo dpkg -i /file/one.deb /file/two.deb /file/three.deb
[16:41] <sirriffsalot> Hmm ok
[16:42] <sirriffsalot> This order did not work sudo dpkg -i /home/sirriffsalot/linux-image-realtime_3.2.0.23.25~precise1_i386.deb linux-headers-realtime_3.2.0.23.25~precise1_i386.deb linux-realtime_3.2.0.23.25~precise1_i386.deb
[16:43] <holstein> sirriffsalot: its not the order.. its the command
[16:43] <sirriffsalot> Oh:S
[16:43] <holstein> you only have the path once
[16:43] <sirriffsalot> Haha
[16:43] <holstein> the path needs to be for each one
[16:43] <sirriffsalot> Ok
[16:44] <sirriffsalot> sudo dpkg -i /home/sirriffsalot/linux-image-realtime_3.2.0.23.25~precise1_i386.deb /home/sirriffsalot/linux-headers-realtime_3.2.0.23.25~precise1_i386.deb /home/sirriffsalot/linux-realtime_3.2.0.23.25~precise1_i386.deb
[16:44] <sirriffsalot> Still error message
[16:44] <sirriffsalot> Ah nvm, haha
[16:45] <sirriffsalot> The files are in /home/sirriffsalot already, no need for that path
[16:45] <holstein> sirriffsalot: depends...i typically just tab complete
[16:45] <sirriffsalot> I do too, apparently I'm an expert in getting the order wrong
[16:46] <holstein> ive been doing that since something that should have taken me about 4 mintues took me a half hour because i had similar errors to troubleshoot
[16:47] <holstein> i used to drag them over from nautilus and let them get "completed" automatically... im no hacker, i just need to get things done and move on
[16:47] <holstein> like is suggest for you.. this kernel is *not* magic
[16:47] <sirriffsalot> Well let's see:)
[16:47] <sirriffsalot> I've done it in every possible order, still get error messages of the same nature:(
[16:47] <holstein> i wouldnt waste a long time chasing rainbows... i fought and fought and wasted time, now i can get 2ms latency
[16:47] <holstein> but, i usually dont
[16:47] <holstein> sirriffsalot: add the ppa
[16:48] <sirriffsalot> Aww
[16:48] <sirriffsalot> Hehe, ah well
[16:48] <holstein> sudo apt-add-repository ppa:kxstudio-team/kernel
[16:48] <holstein> sudo apt-get update
[16:48] <holstein> sudo apt-get install linux-realtime
[16:48] <holstein> reboot, tap shift.. select the kernel.. test.. debate.. decide.. enjoy
[16:49] <sirriffsalot> Yeah, doing that
[16:49] <sirriffsalot> But I need more than just linux-realtime no?
[16:50] <holstein> sirriffsalot: thats the meta-package.. it'll pull in what it needs.. so, yes and no
[16:50] <sirriffsalot> Ok, sec
[16:53] <sirriffsalot> Wtf, linux-realtime, according to synaptic, is already installed, but not the headers hand image
[16:53] <sirriffsalot> Haha
[16:53] <holstein> sirriffsalot: you probably installed something earlier trying to get it without the PPA
[16:54] <sirriffsalot> E: Unable to correct problems, you have held broken packages.
[16:54] <sirriffsalot> E: Unable to lock the download directory
[16:54] <sirriffsalot> Great..
[16:55] <holstein> sirriffsalot: yup.. you really shouldnt do anything like this without knowing about pacakge management.. you can really break things, like i said
[16:55] <sirriffsalot> From synaptic, is it not easier to go for linux-realtime-pae?
[16:55] <sirriffsalot> Hehe
[16:55] <holstein> sirriffsalot: open a terminal... close *everyting* else
[16:55] <holstein> run..
[16:55] <holstein> sudo apt-get update
[16:55] <holstein> report errors
[16:56] <sirriffsalot> Ok:)
[16:56] <sirriffsalot> I really appreciate your time
[16:56] <sirriffsalot> Including vlc and xchat?:P
[16:57] <holstein> sirriffsalot: no worries.. im here for a bit more
[16:57] <sirriffsalot> http://pastebin.com/J6CHf8WQ
[16:58] <holstein> sirriffsalot: sudo apt-get install linux-realtime
[16:58] <holstein> report errors again
[16:59] <sirriffsalot> Ah, that error message earlier was when messing around in synaptic^^
[17:01] <sirriffsalot> On a slow wireless network, this is taking a minute or two
[17:02] <sirriffsalot> Well, I'l getting the restart suggestion here.. I suppose it worked :-S Shall I hold shift to enter the grub menu to select the realtime kernel or?
[17:02] <holstein> tap shift... boot the kernel you choose
[17:04] <sirriffsalot> Fingers crossed:)
[17:04] <sirriffsalot> Cheers! Rebooting
