[05:22] 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. [05:30] I'm seeing severe graphical corruption with Qt programs in xenial [06:00] for example, bring up the About window in VLC [09:23] Good morning. [11:15] 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)? [12:04] ngaio: look up if its' already there in https://bugs.launchpad.net/ ?? -- i'm not an expert on ubuntu bug reporting tbh [12:26] Hey all [12:26] BluesKaj, you're a KDE user right? [12:27] ngaio, yes [12:27] and/or packager [12:27] tester [12:27] have you seen or heard of severe graphical corruption with Qt programs in xenial? [12:28] no, just the odd freeze [12:28] e.g. About screen in VLC [12:28] I get only the title bar of the About window, which is the full screen width, and no content [12:29] do you see that? [12:31] no, I the about popout [12:31] get [12:33] http://ibin.co/2WwBqlvq6MYH [12:33] that's what I'm getting [12:34] hmm okay. I wonder why I'm not. I'm running the standard Unity theme [12:35] my own PyQt program is severely corrupted and in fact doesn't even display [12:35] I'm on plasma 5.5.4 [12:40] ngaio, got python3 ? [12:40] ngaio: Qt4 or Qt5? [12:41] python 3.5, Qt 5 [12:42] Does it throw errors in the terminal? [12:42] yes, I don't recall exactly, but something about gtk widget [12:43] (i'm dual booting, in 15.10 at the moment) [12:43] the gtk widget error is surprising considering they're Qt programs [12:43] Yeah, that is quite odd. [12:43] Is it possible to pastebin your code? [12:43] I did a search on the specific error, and found bugs from 2011 relating to Qt 4 [12:44] it's not just my code though - VLC shows the same problem [12:44] it gives the same error [12:45] how about 15.10 are you on unity there too? ot kde? [12:45] or [12:45] Unity & KDE on 15.10.... won't install KDE on 16.04 unless / until the bug with SSO is fixed [12:45] the telepathy bug [12:46] oh, telepathy, ,never use it [12:48] Wait, you have the problem on both 15.10 and 16.04? [12:49] lordievader, no, it only shows up in 16.04 [12:50] in 15.10 it works as expected [12:51] I'll reboot into 16.04 now to get the exact error message on the terminal [12:53] 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] screenshot is here: http://damonlynch.net/rapid/screenshots/beta/20160128rpd.png [12:54] brb [12:59] this the the VLC about window I'm seeing: http://ibin.co/2WwJn8jsja84 [13:00] that shows the error messages on the console too [13:00] 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. [13:01] !info vlc xenial [13:01] many Qt applications are totally unusable [13:01] 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 [13:02] Haven't run (Kubuntu) Xenial for a while myself, but last time I ran it I didn't notice any problems. [13:02] what's odd is that VirtualBox seems to work okay [13:03] at least the main windows and the preferences [13:03] I dont' dare start an actual VM [13:04] Why not? [13:06] 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 [13:07] * BluesKaj opens the blinds to get more light [13:09] lordievader, because I don't want VirtualBox breaking at the moment when it tries to load another O/S. [13:11] Does docker require an x64 host ? [13:12] aha! when I run my app with Motif style, it works [13:12] so it's a Qt theme problem [13:14] Oehh, would you mind submitting a bug report for that? [13:14] yes I'm just trying to figure out what the default theme is [13:15] maslen, not to worry 16.04 is multiarch by default [13:15] lordievader, do you know what package I should file it against? [13:15] I have no idea what the default Qt theme under Unity is called [13:16] orange and purple :-) [13:17] BluesKaj: What does that mean? [13:17] oh and brown [13:18] maslen, we're talking about the default theme for Qt programs that are run under the Unity desktop [13:18] 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] ngaio: And I was asking about docker :) [13:18] docker can run on both 32 and 64bit [13:19] it's been around since kde3 [13:19] and gnome [13:29] maslen, are you talking about the container app or the graphical panel ?...there seems to be a duplicate name for 2 differnt applications [13:31] !docker [13:31] the container app. docker.io [13:32] who runs 32bit hosts anyway [13:33] 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" [13:35] Think the packagers better come up with a new name for the docking app in the DE [13:38] k1l: I've been using x86 because of ASAN : https://github.com/mirrorer/afl/blob/master/docs/notes_for_asan.txt [13:40] 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] bug #1545450 is filed [13:40] bug 1545450 in unity (Ubuntu) "Severe Qt visual corruption with default Qt theme under Unity" [Undecided,New] https://launchpad.net/bugs/1545450 === not_phunyguy is now known as phunyguy [13:47] k1l: I can only allocate so much RAM to my VMs [14:13] https://wiki.ubuntu.com/XenialXerus/ReleaseSchedule doesnt have the schedule for the pointreleases so far [16:12] good day [16:12] 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] its running a Intel Pentium N3520 processor [16:13] and it seem to happen mostly during gpu access [16:16] 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 :) [17:23] TheOnlyBouncer: Do you have it connected to a network and can you log in when it fails? [17:25] TheOnlyBouncer: Also, how dead is it - e.g. does the capslock key still change the state of the capslock LED ? [18:24] penguin42, nothing reacts anymore, at all, total system freeze (ie. keyboard not reacting etc) [18:24] otherwise i would have switched to a terminal and did some debugging [18:25] did not try if i could ssh in it when crashed though [18:27] TheOnlyBouncer: Worth a try, otherwise, file a bug anyway - probably ubuntu-bug linux just after you reboot [18:33] penguin42, are there any automated logs for crashes that get fetched this way? [18:33] to be honest, i would rather find out what actually goes wrong so i can hotpatch it [18:33] i kind of need that system running [18:34] TheOnlyBouncer: Yeh that can be tricky depending what broke [18:34] 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 [18:35] 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 [18:36] hmm ok will try, thanks [18:36] i don't think it is a kernel panic, which makes me happy :P since that would definitely shown anything [18:37] 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 === rww is now known as dax [20:57] Has anyone experienced problems in xenial with services not starting on boot _some_ times? === alkisg_away is now known as alkisg [20:58] E.g. network-manager, dnsmasq, even lightdm... [20:58] Maybe one out of 20 boots or so [20:58] * alkisg has seen that in 3 different installations so far [21:11] Haven't noticed it yet. Is this a recent trend? [21:13] 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] Hmm, haven't booted my Xenial install in a while. But I can't remember such as issue happening. [21:15] Thanks, I'll check more and file a bug report on that then :)
