| maslen | I'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 |

| ngaio | I'm seeing severe graphical corruption with Qt programs in xenial | 05:30 |
| ngaio | for example, bring up the About window in VLC | 06:00 |
| lordievader | Good morning. | 09:23 |
| ngaio | would 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 |
| enyc | ngaio: look up if its' already there in https://bugs.launchpad.net/ ?? -- i'm not an expert on ubuntu bug reporting tbh | 12:04 |
| BluesKaj | Hey all | 12:26 |
| ngaio | BluesKaj, you're a KDE user right? | 12:26 |
| BluesKaj | ngaio, yes | 12:27 |
| ngaio | and/or packager | 12:27 |
| BluesKaj | tester | 12:27 |
| ngaio | have you seen or heard of severe graphical corruption with Qt programs in xenial? | 12:27 |
| BluesKaj | no, just the odd freeze | 12:28 |
| ngaio | e.g. About screen in VLC | 12:28 |
| ngaio | I get only the title bar of the About window, which is the full screen width, and no content | 12:28 |
| ngaio | do you see that? | 12:29 |
| BluesKaj | no, I the about popout | 12:31 |
| BluesKaj | get | 12:31 |
| BluesKaj | http://ibin.co/2WwBqlvq6MYH | 12:33 |
| BluesKaj | that's what I'm getting | 12:33 |
| ngaio | hmm okay. I wonder why I'm not. I'm running the standard Unity theme | 12:34 |
| ngaio | my own PyQt program is severely corrupted and in fact doesn't even display | 12:35 |
| BluesKaj | I'm on plasma 5.5.4 | 12:35 |
| BluesKaj | ngaio, got python3 ? | 12:40 |
| lordievader | ngaio: Qt4 or Qt5? | 12:40 |
| ngaio | python 3.5, Qt 5 | 12:41 |
| lordievader | Does it throw errors in the terminal? | 12:42 |
| ngaio | yes, I don't recall exactly, but something about gtk widget | 12:42 |
| ngaio | (i'm dual booting, in 15.10 at the moment) | 12:43 |
| ngaio | the gtk widget error is surprising considering they're Qt programs | 12:43 |
| lordievader | Yeah, that is quite odd. | 12:43 |
| lordievader | Is it possible to pastebin your code? | 12:43 |
| ngaio | I did a search on the specific error, and found bugs from 2011 relating to Qt 4 | 12:43 |
| ngaio | it's not just my code though - VLC shows the same problem | 12:44 |
| ngaio | it gives the same error | 12:44 |
| BluesKaj | how about 15.10 are you on unity there too? ot kde? | 12:45 |
| BluesKaj | or | 12:45 |
| ngaio | Unity & KDE on 15.10.... won't install KDE on 16.04 unless / until the bug with SSO is fixed | 12:45 |
| ngaio | the telepathy bug | 12:45 |
| BluesKaj | oh, telepathy, ,never use it | 12:46 |
| lordievader | Wait, you have the problem on both 15.10 and 16.04? | 12:48 |
| ngaio | lordievader, no, it only shows up in 16.04 | 12:49 |
| ngaio | in 15.10 it works as expected | 12:50 |
| ngaio | I'll reboot into 16.04 now to get the exact error message on the terminal | 12:51 |
| ngaio | to 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 :-D | 12:53 |
| ngaio | screenshot is here: http://damonlynch.net/rapid/screenshots/beta/20160128rpd.png | 12:53 |
| ngaio | brb | 12:54 |
| ngaio | this the the VLC about window I'm seeing: http://ibin.co/2WwJn8jsja84 | 12:59 |
| ngaio | that shows the error messages on the console too | 13:00 |
| lordievader | Hmm, 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 xenial | 13:01 |
| ngaio | many Qt applications are totally unusable | 13:01 |
| ubottu | vlc (source: vlc): multimedia player and streamer. In component universe, is optional. Version 2.2.2-3build1 (xenial), package size 1473 kB, installed size 4586 kB | 13:01 |
| lordievader | Haven't run (Kubuntu) Xenial for a while myself, but last time I ran it I didn't notice any problems. | 13:02 |
| ngaio | what's odd is that VirtualBox seems to work okay | 13:02 |
| ngaio | at least the main windows and the preferences | 13:03 |
| ngaio | I dont' dare start an actual VM | 13:03 |
| lordievader | Why not? | 13:04 |
| BluesKaj | one 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 ssd | 13:06 |
| * BluesKaj opens the blinds to get more light | 13:07 | |
| ngaio | lordievader, because I don't want VirtualBox breaking at the moment when it tries to load another O/S. | 13:09 |
| maslen | Does docker require an x64 host ? | 13:11 |
| ngaio | aha! when I run my app with Motif style, it works | 13:12 |
| ngaio | so it's a Qt theme problem | 13:12 |
| lordievader | Oehh, would you mind submitting a bug report for that? | 13:14 |
| ngaio | yes I'm just trying to figure out what the default theme is | 13:14 |
| BluesKaj | maslen, not to worry 16.04 is multiarch by default | 13:15 |
| ngaio | lordievader, do you know what package I should file it against? | 13:15 |
| ngaio | I have no idea what the default Qt theme under Unity is called | 13:15 |
| BluesKaj | orange and purple :-) | 13:16 |
| maslen | BluesKaj: What does that mean? | 13:17 |
| BluesKaj | oh and brown | 13:17 |
| ngaio | maslen, we're talking about the default theme for Qt programs that are run under the Unity desktop | 13:18 |
| lordievader | ngaio: 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 |
| maslen | ngaio: And I was asking about docker :) | 13:18 |
| BluesKaj | docker can run on both 32 and 64bit | 13:18 |
| BluesKaj | it's been around since kde3 | 13:19 |
| BluesKaj | and gnome | 13:19 |
| BluesKaj | maslen, are you talking about the container app or the graphical panel ?...there seems to be a duplicate name for 2 differnt applications | 13:29 |
| BluesKaj | !docker | 13:31 |
| maslen | the container app. docker.io | 13:31 |
| k1l | who runs 32bit hosts anyway | 13:32 |
| BluesKaj | because 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 |
| BluesKaj | Think the packagers better come up with a new name for the docking app in the DE | 13:35 |
| maslen | k1l: I've been using x86 because of ASAN : https://github.com/mirrorer/afl/blob/master/docs/notes_for_asan.txt | 13:38 |
| k1l | maslen: 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 |

| TheOnlyBouncer | good day | 16:12 |
| TheOnlyBouncer | i 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 |
| TheOnlyBouncer | its running a Intel Pentium N3520 processor | 16:12 |
| TheOnlyBouncer | and it seem to happen mostly during gpu access | 16:13 |
| TheOnlyBouncer | i 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 |
| penguin42 | TheOnlyBouncer: Do you have it connected to a network and can you log in when it fails? | 17:23 |
| penguin42 | TheOnlyBouncer: Also, how dead is it - e.g. does the capslock key still change the state of the capslock LED ? | 17:25 |
| TheOnlyBouncer | penguin42, nothing reacts anymore, at all, total system freeze (ie. keyboard not reacting etc) | 18:24 |
| TheOnlyBouncer | otherwise i would have switched to a terminal and did some debugging | 18:24 |
| TheOnlyBouncer | did not try if i could ssh in it when crashed though | 18:25 |
| penguin42 | TheOnlyBouncer: Worth a try, otherwise, file a bug anyway - probably ubuntu-bug linux just after you reboot | 18:27 |
| TheOnlyBouncer | penguin42, are there any automated logs for crashes that get fetched this way? | 18:33 |
| TheOnlyBouncer | to be honest, i would rather find out what actually goes wrong so i can hotpatch it | 18:33 |
| TheOnlyBouncer | i kind of need that system running | 18:33 |
| penguin42 | TheOnlyBouncer: Yeh that can be tricky depending what broke | 18:34 |
| penguin42 | TheOnlyBouncer: 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 on | 18:34 |
| penguin42 | TheOnlyBouncer: 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 logs | 18:35 |
| TheOnlyBouncer | hmm ok will try, thanks | 18:36 |
| TheOnlyBouncer | i don't think it is a kernel panic, which makes me happy :P since that would definitely shown anything | 18:36 |
| penguin42 | TheOnlyBouncer: 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 stops | 18:37 |

| alkisg_away | Has anyone experienced problems in xenial with services not starting on boot _some_ times? | 20:57 |
| === alkisg_away is now known as alkisg | ||
| alkisg | E.g. network-manager, dnsmasq, even lightdm... | 20:58 |
| alkisg | Maybe one out of 20 boots or so | 20:58 |
| * alkisg has seen that in 3 different installations so far | 20:58 | |
| lordievader | Haven't noticed it yet. Is this a recent trend? | 21:11 |
| alkisg | I'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 issue | 21:13 |
| lordievader | Hmm, haven't booted my Xenial install in a while. But I can't remember such as issue happening. | 21:13 |
| alkisg | Thanks, I'll check more and file a bug report on that then :) | 21:15 |
