apwdiwic, hey ... i seem to have lost sound on my main "desktop" with 3.15, and i wondered how i could figure that out11:23
diwicapw, are all outputs affected?11:24
apwdiwic, all internal ones, i have external USB connected speakers which work11:25
diwicapw, if you run "ubuntu-bug audio" and go through the sound test, is any of the sound tests working?11:25
apwis it complaining about mixer settings11:27
apwthough the command it asks me to run is wrong11:28
diwicapw, okay...could you be more precise?11:30
apwok found the card by hand and the mixer setting it whines about (speaker volume) was 0% and fixing that has fixed sound11:30
apwthe command was "alsamixer -D hw:intel" which didnt work11:31
diwicapw, it's usually big "I" in "Intel"11:31
diwicapw, but send me your alsa-info and I'll have a look11:31
apwyeah big I finds it, perhaps i missread the prompt, yep missread, it is in a stupid font which looks like a little i, sigh11:32
apwok, anyhow, i assume this is lost alsa settings on upgrade thing?11:32
apwdo you still want my alsa-info ?11:32
diwicapw, well the question is more like, why didn't pulseaudio change the speaker setting to something reasonable. Or, if you don't have any internal speakers, why do you have such a mixer setting at all11:33
diwic(you said it was a desktop rather than a laptop)11:34
apwdiwic, ahh this is a laptop in a desktop environment, monitors attached etc, so its not mobile ever, but it is a lappy, hense the "desktop"11:35
apwit has something plugged in each and every possible port :)11:35
diwicapw, what port is selected in PulseAudio ( what line is selected in sound settings -> output )11:36
apwdiwic, when i am testing the speakers it is on "Speakers"11:37
diwicapw, well, then just changing the volume in pulseaudio would also change the speaker volume11:38
apwas that is the setting it has to be on to use the headphone sockets, i switch it there to the USB speakers for the rest of the time11:38
apwdiwic, ok so the speaker volume was set to a normal value and was working on the USB ones11:38
apwwhen i switched internal it was silent, until i used alsa mixer to fix the volume11:39
apw"speaker volume" meaning pulse's one on the top bar11:39
apwand switching from one to the other swaps the volume to the per channel volume in pulse too11:40
apwvery odd11:40
apwvery odd that it could be out of sync until i did the adjustment11:40
diwicapw, yeah, switching to internal should update alsa's speaker volume to something reasonable11:41
apwdiwic, ok, if i watch alsamixer and change pulses volume when on internal11:42
apwthen pulse is changing "master" and not "speaker"11:42
diwicapw, sure, but if you set alsa's speaker to something and then move pulse's slider, alsa's speaker is moved to maximum11:42
apwdiwic, yes it does, hmmm, oh of course i may not have changed volume, on internal ever11:43
apwsince the issue appeared, presumably in a kernel update lose of settings11:43
apwas i would switch to USB, find volume works, move to internal, find it broke, whine11:44
* apw notes that the order of his audio devices in alsa-mixer seems different today, in that the internal is not card 011:44
diwicapw, anyway - if you find a way to reproduce the error let me know. Otherwise I'll just let it slip.11:44
apwdiwic, yep, as i am running a devel kernel i think that is most appropriate :)  thanks for the help, i have more tools to work it out next time11:45
diwicapw, btw, while I have you around - I'm seeing some bluetooth headset errors and most of them seem to be a userspace bug I'm currently trying to track down,11:45
diwicapw, but at least one or two had some weird dmesg errors, let me find them 11:46
diwicapw, in bug 1283003, "Bluetooth: re-auth of legacy device is not possible." "Protocol not supported (93)"11:47
ubot5bug 1283003 in gnome-bluetooth (Ubuntu) "[Bluetooth + 14.04] Bluetooth headsets are not working after last couple of updates" [Undecided,Confirmed] https://launchpad.net/bugs/128300311:47
diwicapw, the latter one is from userspace, the first one from kernel11:48
apwthere is only one bug number there11:50
diwicapw, yeah, it's the "we report all people in one big bug" story11:51
diwicapw, but for the "re-auth of legacy device is not possible" part, is there anything we should/could do about that? 11:52
apwdiwic, well that code seems similar in 13.10 as it does in 14.04, so it is not clear it is that which is at fault11:54
diwicapw, okau11:54
apwVoyager bluetoothd[716]: Protocol not supported (93)11:55
apwhow does bluetoothd think that is a reasonable error11:55
apwwhat the hell was it doing when it got errno = 9311:55
diwicapw, okay, let's fix blueman first and see how far that gets us w r t resolving the bugs. 11:57
apwdiwic, so it seems we have limited ways that bluetooth can say that, and may imply we have a module missing, will check11:59
apwdiwic, ok everything i would expect is enabled so, hard to be sure, we really need to get bluetoothd to tell us what i was doing if it still fails12:03
diwicapw, okay. Thanks for the look12:03
apwdiwic, as for the errors and their order, i suspect they try and auth the device, the device is of a type which cannot, so bluetoothd closes and reopens it some differnt way and that fails12:04
apwbut ... what ... harder to say12:04
apwdiwic, it is generally good at reporting what caused the error, though there are one or two places12:09
apwdiwic, then again it uses the saem internal errors ... so for example if a device says HCI_UNSUPPORTED_REMOTE_FEATURE then it switches that to errno 9312:11
apwwhich ... could mean it is not kernel at all ... ugle12:11
diwicapw, hmm, okay...the reason I thought it was kernel was mostly because the kernel dmesg was first12:11
apwdiwic, yeah, it is not clear that that is a fatal thing, as it it might be a normal process connecting and reconnecting in dumber modes12:12
apwand we had the same basic code before, though if they can down grade just the kerenl and it changes then there is a kernel component12:13
apwdiwic, ok that "error" is informational only and says that we failed to encrypt the link, but the link remains12:14
diwicbtw, is the hwe backport stuff going to work (in general) like it did for 12.04? I e 14.04.2 will ship with utopic kernel and x stack12:18
bjfdiwic, i can't really speak for anything other than the kernel but yes, there will be a series of lts-<series> kernels for trusty which will also be the defaults for the future point releases12:22
diwicbjf, ok, good to know12:24

vmlintuHi, I'm trying to understand the 3.13 kernel maintenance process. How the patches end up there? The tree here has seen no activity for some time: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;h=refs/heads/linux-3.13.y;a=shortlog  Am I looking at the right place?14:30
vmlintuWhat I'm trying to figure out if this patch marked for stable is on its way to Ubuntu's kernel or if something needs to be done for it to end up there: http://www.spinics.net/lists/netdev/msg282079.html14:31
rtgvmlintu, git://kernel.ubuntu.com/ubuntu/ubuntu-trusty.git14:32
vmlinturtg: ok, I'm cloning that.. is that the Ubuntu flavoured kernel?14:35
vmlintuIs git://kernel.ubuntu.com/ubuntu/linux.git going to get updates or should I follow only the ubuntu-trusty.git repo on updates?14:38
rtgvmlintu, linux.git is where updates for the stable kernels that we maintain are kept. ubuntu-trusty.git is where those updates go before the kernel is built and published.14:40
vmlintuok, it looks like the patch is not there in master-next14:45
vmlintuIs something needed for the stable patches to be merged? The breaking patch was introduced in 3.13 and the fix went in stable kernel 3.14.5. Should I send mail to the kernel-team mailing list?15:00
rtgvmlintu, you should send an email to stable@vger.kernel.org requesting that the patch be included in 3.13 stable.15:02
vmlinturtg: thanks, I'll do that. I haven't really gotten myself familiar with the 3.13 stable process after Ubuntu kernel team took over it.15:06
rtgvmlintu, it is largely the same, just different maintainers15:06
vmlinturtg: ok, that's good to know. Thanks for help!15:08

dsmythiesHi, I wonder if anyone can help me. I am investigating an issue where (it appears as though) deferrable timers are being15:51
dsmythiesdeferred for to long (sometimes much too long) and to often.15:51
dsmythiesWhat I have done is compiled with CONFIG_DEBUG_OBJECTS_TIMERS and I vaquely read somewhere that I also need my grub line15:51
dsmythiesto include ignore_loglevel, which I have. However, I am not seeing any additional information anywhere, including dmesg.15:51
dsmythiesWhere would I find the additional information, if it is being generated? Or, what am I missing to generate it?15:51

shadeslayerhi \o16:49
jsalisburyshadeslayer, o/16:49
shadeslayerjsalisbury: re https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1310402 , would it be possible to change the scheduler to cfq?16:51
ubot5Ubuntu bug 1310402 in linux (Ubuntu) "Userland depends on ionice idle but default scheduler is "deadline". " [Wishlist,Triaged]16:51
shadeslayeror maybe even change it for Kubuntu? ( in which case, what kind of issues could we be facing )16:51
jsalisburyshadeslayer, there is allot of testing and discussion to decide on which scheduler to use by default.  You do have the ability to change the scheduler for your particular system.16:54
shadeslayerI understand that, but deadline doesn't work out for the needs of Kubuntu/KDE since the file indexer uses features such as io niceness which are not available via deadline16:55
vHandajsalisbury: do you any data to backup why the change was made for the deskop?16:58
jsalisburyshadeslayer, we can request that the default scheduler be changed for the current or next development release, but I'm not so sure we could have it changed for any stable releases.16:58
jsalisburyvHanda, it was discussed at a prior UDS and should be in the minutes/notes from UDS.  17:00
shadeslayerjsalisbury: right, and any ideas on whether changing it specifically for Kubuntu would mess up anything else in foundations?17:01
shadeslayeri.e. is there stuff in foundations that expects the scheduler to be deadline17:01
jsalisburyshadeslayer, that's a good question.  I really don't know the answer off hand.  apw or cking do you happen to know ^^^  If not, it's something that would have to be researched.17:02
vHandaI had only found this - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1008400/comments/1617:03
ubot5Ubuntu bug 1008400 in linux (Ubuntu) "Ubuntu server uses CFQ scheduler instead of deadline" [Medium,In progress]17:03
apwshadeslayer, so that was performance related, that cfq was not performing well and got switched to deadline generally17:04
ckingbut it is useful to know the corner cases where deadline may suck17:04
apwcking, sunds like it is not feature compatible with cfq17:04
apwshadeslayer, as this can be changed on the fly, i assume we can just change it at boot time17:04
vHandaapw: cfq was not performing well for desktop use or server?17:04
apwdesktop, never has for server according to the server folk17:05
apwit was a key contributer to the going unresponsive for a long time issues we were seeing back at the change17:05
ckinglike all "defaults", it tries to do the best for most classes of use cases17:06
vHandaCould you please point me to some documentation regarding these "use cases" and data showing it was not performing well.17:07
apwvHanda, it was a fair time ago, iirc the graphs etc were sent to the kernel-team@ list and should be in the archives17:08
vHandaI have users complaining about the file indexer using a decent amount of IO and without niceness it renders there system quite slugish.17:08
apwvHanda, so change the default at boot time on kubuntu ?17:08
apwand be happy17:08
apwit is runtime configurable after all17:09
shadeslayerapw: right, for that, do you know if kubuntu can switch out deadline for cfq and things won't break apart ?17:09
vHandaI see this - https://lists.ubuntu.com/archives/kernel-team/2013-July/030360.html17:10
apwshadeslayer, you can change it at any time even under load and it should just work17:10
vHandawhich is completely right but disregards mechanical rotational medium17:10
vHandaanyway, I'll look more17:10
ckingvHanda, it's older than that, that was for a phone config17:10
shadeslayerapw: ack17:11
shadeslayerI'll have a look and try it get changed for 14.1017:12
shadeslayerfor Kubuntu17:12
shadeslayerapw: btw is there a way to set the default scheduler as a config file ( as opposed to passing it at boot time )17:15
* cking wonders if a udev rule will suffice, as mentioned in http://askubuntu.com/questions/78682/how-do-i-change-to-the-noop-scheduler17:19
