| mc888 | anybody here? | 02:54 |
|---|---|---|
| holstein | yes | 02:54 |
| mc888 | hi | 02:54 |
| mc888 | I may have something wrong with my kxstudio installation, not sure | 02:55 |
| holstein | well, you should have backups, regardless | 02:55 |
| mc888 | should I have ppas in software sources for both trusty and lucid at the same time? | 02:55 |
| holstein | could be, you have nothing wrong with the OS, but, the hard drive is failing, as all do/will | 02:56 |
| mc888 | right, well thats why I have a mirror :) | 02:56 |
| holstein | mc888: did you do a stock install? are you actually having issues? | 02:56 |
| mc888 | yeah I installed from iso last year | 02:56 |
| holstein | ok. so, if its a stock install, and you havent added any incorrect sources, and all is well, that seems normal | 02:57 |
| mc888 | not sure I should have the old lucid updates in my sources | 02:57 |
| holstein | mc888: cool | 02:57 |
| holstein | mc888: you can wait around, and ask, or email falk, if you like | 02:57 |
| holstein | mc888: or, you can disable them, and try | 02:58 |
| holstein | mc888: but, if you literally didnt add the sources, and its stock, that sounds "normal" to me | 02:58 |
| holstein | but, do what you like.. | 02:58 |
| mc888 | I did disable them, but apt-get doesnt remove any old versions | 02:58 |
| holstein | sure | 02:58 |
| holstein | its not meant to | 02:58 |
| holstein | but, you likely shouldnt have disabled them.. | 02:58 |
| mc888 | easy enough to re-enable | 02:58 |
| holstein | anyways, you would have to remove the packages manually.. or, use ppa-purge.. | 02:59 |
| mc888 | ah thats it | 02:59 |
| holstein | but, if nothing is wrong, i wouldnt try and fix anything | 02:59 |
| mc888 | heh | 02:59 |
| mc888 | alright thanks, Ill ask falk if lucid should be purged | 03:01 |
| holstein | well, if its stock, and he put them there, then, you dont need to | 03:01 |
| mc888 | right, but Im starting to think the older versions may be causing issues | 03:03 |
| holstein | cool | 03:03 |
| holstein | add newer ones, if you like | 03:03 |
| holstein | they literally should be quite static | 03:03 |
| holstein | you can have issues if you expect newer functionality from the older applications.. | 03:03 |
| mc888 | so it shouldnt matter if theyre both installed? | 03:03 |
| mc888 | this is a trusty build | 03:04 |
| holstein | they are custom sources | 03:04 |
| holstein | even the lucid ones.. still just falk maintaining them | 03:05 |
| holstein | they are standalone, from what i understand | 03:05 |
| holstein | i dont think he has a need to re-make them.. | 03:05 |
| mc888 | right, I understand that - but I have installed packages from both sources | 03:05 |
| holstein | sure. and is that a problem? | 03:05 |
| mc888 | well thats my question :) | 03:06 |
| holstein | mc888: friend, are you having a problem? | 03:06 |
| holstein | if not, then you are running the stock OS.. | 03:06 |
| holstein | i was told, the sources are stand alone.. self contained | 03:06 |

| halfbeing | i'm getting lots of xruns running reaper via wineasio and wine-rt on ubuntu vivid (with low latency kernel). i have heard that some kernels are more wine-friendly than others when it comes to audio. is there a better kernel i can use or a distribution with a kernel more suited to audio via wine? | 03:56 |
| holstein | i would start with the generic one.. then, since, you have tried the lowlatency, i would look for an RT one.. there is a deb for the avlinux one | 03:58 |
| holstein | i dont think there will be a "better" kernel at running windows code.. | 03:58 |

| audioterminal | Anyone using ardour? I installed a new hdd to keep ardour sessions there, but I get an error | 09:09 |

| audioterminal | Hi there is a lot I need to learn still about linux and I just got a second HDD to keep ardour sessions there. What format do you recomend I use on the new SATA HDD? | 09:25 |
| audioterminal | ext4? | 09:26 |

| *** dtcrshr has joined #kxstudio | 10:41 | |
| JackWinter | audioterminal: ext4 ought to be ok | 11:24 |
| JackWinter | optionally you might want to use the noatime when you mount it. | 11:25 |
| JackWinter | as to not being able to create sessions, does it have the right permissions so that your user can use it? | 11:25 |
| JackWinter | and it's a good idea to keep all your ardour sessions on a different disk, as keeping them on the same disk as /home might give you the occasional xrun | 11:27 |
| audioterminal | I just set the permisions to my username using dolphin with sudo | 11:29 |
| audioterminal | I will figure out what the noatime is but I will set it somehow | 11:30 |
| audioterminal | I will keep all my ardour sessions on the new Hard drive | 11:31 |
| audioterminal | Thank you JackWinter | 11:31 |
| audioterminal | Few days back you helped me with my firewire audio interface. It solved the xrun problems even without the new Hard drive | 11:32 |
| audioterminal | I got the new HDD just to make sure I do not get xruns later on | 11:33 |
| audioterminal | Thank you | 11:33 |
| JackWinter | yw. if you want to test xruns vs disk io, running bonnie++ on the disks while running an ardour prj will most likely show you the xruns | 11:35 |
| audioterminal | Is not enough cadence log to notice xruns? | 11:38 |
| *** distrozapper has quit IRC | 11:39 | |
| audioterminal | I will read about bonnie++ to see what you are talking about. Thank you again | 11:40 |
| JackWinter | audioterminal: bonnie++ is a disk benchmarking program, so it really hammers the disk io system. now you'll probably find that if you run it on the same disk that ardour is reading it's audio data from that you'll get the occasional xruns as ardour no longer can read data quickly enough. | 11:47 |
| JackWinter | seen like that it shows xruns much quickly than just running ardour and doing your normal computing. i had xruns a couple of times a day, until i figured out that it was due to me keeping the audio data on my /home disk. but bonnie++ allowed me to verify it much more quickly. | 11:48 |
| JackWinter | the problems with xruns is that there can be many different reasons for them, so sometimes hard to verify exactly the source of the problem | 11:49 |
| audioterminal | I am having problems understanding how to set the noatime mount option | 11:58 |
| audioterminal | my new hardrive does not show on /etc/fstab | 11:59 |

| audioterminal | I figured to set noatime It is not that dificult after all | 12:49 |
| audioterminal | I used the UUID instead of /dev/sdb1 | 12:50 |
| audioterminal | the setting I used was defaults,noatime I hope that part was ok | 12:52 |

| halfbeing | JackWinter: is it ok to use a non-ubuntu -rt kernel with ubuntu? will things break? | 15:58 |
| falktx | try it | 15:59 |
| HarryHaaren | halfbeing, yes should be fine. Will things break - hard to know, but they shouldn't ;) | 16:00 |
| falktx | well, they can | 16:05 |
| falktx | the iolinux kernel is broken | 16:05 |
| *** wolftune has quit IRC | 16:05 | |
| falktx | avlinux one works, sorta | 16:05 |

| *** rncbc has joined #kxstudio | 17:11 | |
| JackWinter | halfbeing: i think it ought to work, unless userland is relying on something in the kernel config which is missing from your rt kernel. note that out of tree modules like nvidia, vbox, etc might break.. | 17:12 |
| JackWinter | in any case just install it and try to boot it (while leaving the ubuntu kernel installed), if something breaks badly you are only a reboot away from the ubuntu kernel | 17:13 |
| *** orngjce223 has joined #kxstudio | 17:30 | |
| halfbeing | i've just noticed that in ubuntu vivid i no longer have a choice of frequency governor. i only have ondemand. would having a performance governor improve performance of reaper in wine? if so, could i enable it in grub, rather than having to build a custom kernel? | 17:41 |
| falktx | did you did an upgrade? | 17:48 |

| JackWinter | halfbeing: i think that might depend on the cpu. for instance my i7 runs perfectly fine with ondemand. it switches C and P states without any issues. suppose best would be to try. normally you can also change it at runtime, no need to set it on boot (unless you want to) | 21:22 |
| *** BitPuffin|osx has joined #kxstudio | 21:25 | |
| *** anonimoinc has quit IRC | 21:31 | |
| *** BitPuffin|osx has quit IRC | 21:48 | |
| halfbeing | JackWinter, the options to change governor are entirely missing. Ondemand is the only option available. | 21:51 |
| falktx | I had that error too, some old stuff on /etc/modules caused it | 21:51 |
| falktx | I needed some custom modules to make my i7 governors work on old kernels, which are not needed anymore | 21:51 |
| halfbeing | would that be another good reason to roll my own kernel? | 21:52 |
| JackWinter | don't think i've ever seen that. | 21:53 |
| *** designbybeck has quit IRC | 21:53 | |
| JackWinter | but then again i'm not running ubuntu :) | 21:53 |
| JackWinter | i know there was a problem for a while to change the cpu governor on linux-rt, but afaik it's been fixed in all rt versions. | 21:54 |
| halfbeing | i've got a question about rolling a kernel. i tried to apply the 3.18.13 rt patch to the 3.18.13 vanilla sources and it failed, detecting a previously applied patch. any idea how i can get round this? | 21:55 |
| JackWinter | also k8-powernow (or whatever it's called) is disabled on rt kernels | 21:55 |
| JackWinter | halfbeing: did you apply the right patch? https://www.kernel.org/pub/linux/kernel/projects/rt/3.18/patch-3.18.16-rt13.patch.xz | 21:56 |
| JackWinter | or possibly you had already patched it once? | 21:56 |
| JackWinter | sorry i mean: https://www.kernel.org/pub/linux/kernel/projects/rt/3.18/older/patch-3.18.13-rt10.patch.xz | 21:57 |
| halfbeing | i think i see where i may have gone wrong. i'll try again later on today. thanks everyone for your help once again. | 21:59 |
