maslenI'm trying to set up the aflize docker image (https://github.com/d33tah/aflize) , but when I run docker with "docker run -ti d33tah/afl-sid bash", I get an error: "System error: exec format error" . I'm on Ubuntu 16.04. This is my first time using docker, so I apologize for any noob mistakes.05:22
ngaioI'm seeing severe graphical corruption with Qt programs in xenial05:30
ngaiofor example, bring up the About window in VLC06:00
lordievaderGood morning.09:23
ngaiowould anyone like to assist me in possibly filing a bug about severe graphics corruption with Qt programs in Xenial (assuming no one did already, which would be surprising)?11:15
enycngaio: look up if its' already there in  https://bugs.launchpad.net/  ?? -- i'm not an expert on ubuntu bug reporting tbh12:04
BluesKajHey all12:26
ngaioBluesKaj, you're a KDE user right?12:26
BluesKajngaio, yes12:27
ngaioand/or packager12:27
BluesKajtester12:27
ngaiohave you seen or heard of severe graphical corruption with Qt programs in xenial?12:27
BluesKajno, just the odd freeze12:28
ngaioe.g. About screen in VLC12:28
ngaioI get only the title bar of the About window, which is the full screen width, and no content12:28
ngaiodo you see that?12:29
BluesKajno, I the about  popout12:31
BluesKajget12:31
BluesKajhttp://ibin.co/2WwBqlvq6MYH12:33
BluesKajthat's what I'm getting12:33
ngaiohmm okay. I wonder why I'm not. I'm running the standard Unity theme12:34
ngaiomy own PyQt program is severely corrupted and in fact doesn't even display12:35
BluesKajI'm on plasma 5.5.412:35
BluesKajngaio, got python3 ?12:40
lordievaderngaio: Qt4 or Qt5?12:40
ngaiopython 3.5, Qt 512:41
lordievaderDoes it throw errors in the terminal?12:42
ngaioyes, I don't recall exactly, but something about gtk widget12:42
ngaio(i'm dual booting, in 15.10 at the moment)12:43
ngaiothe gtk widget error is surprising considering they're Qt programs12:43
lordievaderYeah, that is quite odd.12:43
lordievaderIs it possible to pastebin your code?12:43
ngaioI did a search on the specific error, and found bugs from 2011 relating to Qt 412:43
ngaioit's not just my code though - VLC shows the same problem12:44
ngaioit gives the same error12:44
BluesKajhow about 15.10 are you on unity there too? ot kde?12:45
BluesKajor12:45
ngaioUnity & KDE on 15.10.... won't install KDE on 16.04 unless / until the bug with SSO is fixed12:45
ngaiothe telepathy bug12:45
BluesKajoh, telepathy, ,never use it12:46
lordievaderWait, you have the problem on both 15.10 and 16.04?12:48
ngaiolordievader, no, it only shows up in 16.0412:49
ngaioin 15.10 it works as expected12:50
ngaioI'll reboot into 16.04 now to get the exact error message on the terminal12:51
ngaioto answer your question about my code, it's on launchpad as lp:rapid. You can get it with bzr. Don't run the setup.py though, I'm still coding that and in any case some dependencies can only be installed with pip :-D12:53
ngaioscreenshot is here: http://damonlynch.net/rapid/screenshots/beta/20160128rpd.png12:53
ngaiobrb12:54
ngaiothis the the VLC about window I'm seeing: http://ibin.co/2WwJn8jsja8412:59
ngaiothat shows the error messages on the console too13:00
lordievaderHmm, at first I thought it was a problem with your application, specifically. But if more applications suffer the same fate it would make you think a library is the culprit.13:00
lordievader!info vlc xenial13:01
ngaiomany Qt applications are totally unusable13:01
ubottuvlc (source: vlc): multimedia player and streamer. In component universe, is optional. Version 2.2.2-3build1 (xenial), package size 1473 kB, installed size 4586 kB13:01
lordievaderHaven't run (Kubuntu) Xenial for a while myself, but last time I ran it I didn't notice any problems.13:02
ngaiowhat's odd is that VirtualBox seems to work okay13:02
ngaioat least the main windows and the preferences13:03
ngaioI dont' dare start an actual VM13:03
lordievaderWhy not?13:04
BluesKajone thing I did notice is thay 16.04 is much slower to load tje desktop after boot and packages than 14.04, and I'm dual booting both OSs on the same ssd13:06
* BluesKaj opens the blinds to get more light13:07
ngaiolordievader, because I don't want VirtualBox breaking at the moment when it tries to load another O/S.13:09
maslenDoes docker require an x64 host ?13:11
ngaioaha! when I run my app with Motif style, it works13:12
ngaioso it's a Qt theme problem13:12
lordievaderOehh, would you mind submitting a bug report for that?13:14
ngaioyes I'm just trying to figure out what the default theme is13:14
BluesKajmaslen, not to worry 16.04 is multiarch by default13:15
ngaiolordievader, do you know what package I should file it against?13:15
ngaioI have no idea what the default Qt theme under Unity is called13:15
BluesKajorange and purple :-)13:16
maslenBluesKaj: What does that mean?13:17
BluesKajoh and brown13:17
ngaiomaslen, we're talking about the default theme for Qt programs that are run under the Unity desktop13:18
lordievaderngaio: I think the theme is called breeze, but I am not sure if that is a seperate package and/or if Unity uses that by default.13:18
maslenngaio: And I was asking about docker :)13:18
BluesKajdocker can run on both 32 and 64bit13:18
BluesKajit's been around since kde313:19
BluesKajand gnome13:19
BluesKajmaslen, are you talking about the container app or the graphical panel ?...there seems to be a duplicate name for 2 differnt applications13:29
BluesKaj!docker13:31
maslenthe container app. docker.io13:31
k1lwho runs 32bit hosts anyway13:32
BluesKajbecause when I refernced docker in muon this what I got: "Docker is a docking application (WindowMaker dock app) which acts as a system tray for any desktop environment"13:33
BluesKajThink the packagers better come up with a new name for the docking app in the DE13:35
maslenk1l: I've been using x86 because of ASAN : https://github.com/mirrorer/afl/blob/master/docs/notes_for_asan.txt13:38
k1lmaslen: you are aware that this is not a real issue on todays ram sizes? 32bit is going to die slowly. faster than flash, but still slowly. chrome dropped 32bit support. first linux distributions dropping 32bit isos.13:40

TheOnlyBouncergood day16:12
TheOnlyBounceri have a Lenovo yoga 2-11 which is running the current alpha for 16.04 but i am getting occasional total system freezes. Since i can not do anything, is there a way to debug this to commit a bug report?16:12
TheOnlyBouncerits running a Intel Pentium N3520 processor16:12
TheOnlyBouncerand it seem to happen mostly during gpu access16:13
TheOnlyBounceri must admit that i did not try another distro or version of ubuntu yet (since i really wanted a 4.4 kernel or newer), but i rather figure out how to debug this :)16:16
penguin42TheOnlyBouncer: Do you have it connected to a network and can you log in when it fails?17:23
penguin42TheOnlyBouncer: Also, how dead is it - e.g. does the capslock key still change the state of the capslock LED ?17:25
TheOnlyBouncerpenguin42, nothing reacts anymore, at all, total system freeze (ie. keyboard not reacting etc)18:24
TheOnlyBouncerotherwise i would have switched to a terminal and did some debugging18:24
TheOnlyBouncerdid not try if i could ssh in it when crashed though18:25
penguin42TheOnlyBouncer: Worth a try, otherwise, file a bug anyway - probably   ubuntu-bug linux     just after you reboot18:27
TheOnlyBouncerpenguin42, are there any automated logs for crashes that get fetched this way?18:33
TheOnlyBouncerto be honest, i would rather find out what actually goes wrong so i can hotpatch it18:33
TheOnlyBounceri kind of need that system running18:33
penguin42TheOnlyBouncer: Yeh that can be tricky depending what broke18:34
penguin42TheOnlyBouncer: I'd start by seeing if you can ssh in, if you can then that makes it a LOT easier to see what's going on18:34
penguin42TheOnlyBouncer: But check /var/log/syslog and syslog.1 or kernel.log and kern.log.1  to  see if they have anything from the crash, but if it crashes hard it often can't write the logs18:35
TheOnlyBouncerhmm ok will try, thanks18:36
TheOnlyBounceri don't think it is a kernel panic, which makes me happy :P since that would definitely shown anything18:36
penguin42TheOnlyBouncer: There are some other tricks as well - e.g. if you can get it to fail while it's in text mode console then you might be able to see a crash message - but it's quite hard if it just stops18:37

alkisg_awayHas anyone experienced problems in xenial with services not starting on boot _some_ times?20:57
=== alkisg_away is now known as alkisg
alkisgE.g. network-manager, dnsmasq, even lightdm...20:58
alkisgMaybe one out of 20 boots or so20:58
* alkisg has seen that in 3 different installations so far20:58
lordievaderHaven't noticed it yet. Is this a recent trend?21:11
alkisgI'm not sure, I've been using xenial on one pc since months, but I only rebooted it once per month or so... the other 3 installations are recent, from 2 to 20 days old, and they all have the issue21:13
lordievaderHmm, haven't booted my Xenial install in a while. But I can't remember such as issue happening.21:13
alkisgThanks, I'll check more and file a bug report on that then :)21:15
